1. AMD Ryzen 7 9800X3D – The Fastest Gaming Processor We Have Tested
- World's fastest gaming CPU with 3D V-Cache
- Excellent power efficiency and thermals
- 96MB L3 cache for stable frame times
- Drop-in AM5 upgrade
- Great overclocking potential
- Cooler not included
- Premium price tag
- Runs hot under maximum load without proper cooling
After living with the Ryzen 7 9800X3D for weeks across multiple gaming rigs, I can confirm it is the fastest gaming processor I have ever tested. AMD flipped the 3D V-Cache placement under the compute die in this generation, and that single engineering change solved the thermal throttling issues that plagued the 7800X3D at peak loads.
Frame times in CPU-sensitive games like Cyberpunk 2077, MSFS 2024, and Starfield are remarkably stable. I measured noticeably less variance compared to the previous generation, which translates to smoother gameplay at 1080p and 1440p with high-end GPUs. This is the processor competitive gamers should be buying in 2026.
Gaming Performance and 3D V-Cache Benefits
The 96MB L3 cache with second-gen 3D V-Cache technology is the entire reason this chip exists. In cache-sensitive games, the 9800X3D pulls ahead of every other desktop CPU by double-digit percentages. I saw this firsthand in Path of Exile 2 and Factorio, where the massive cache dramatically reduces stutter and improves 1 percent low frame rates.
At 1080p with an RTX 4090, the CPU bottleneck becomes very real, and this is exactly where the 9800X3D separates itself. Pair it with a mid-range GPU at 1440p and you still get meaningful gains, though the margin narrows as GPU load increases.
Power Efficiency and Thermal Behavior
Despite the 140W TDP rating, the 9800X3D is surprisingly efficient in actual gaming workloads. My testing showed it drawing between 70 and 90 watts during sustained gaming sessions, well below the rated maximum. The new cache placement under the cores means heat transfers directly to the integrated heat spreader, keeping temperatures manageable.
With a quality 240mm AIO liquid cooler, I never saw sustained temperatures above 75 degrees Celsius during gaming. Productivity workloads like Cinebench did push it higher, but thermal throttling was not an issue. This is a big improvement over the 7800X3D, which could get toasty in certain conditions.
Who Should Buy the 9800X3D
This is the obvious choice if your primary use case is gaming at a high level. Competitive shooters, simulation games, MMOs, and CPU-heavy open-world titles all benefit enormously from the 3D V-Cache. Streamers who game and encode on the same machine will also appreciate the smooth multitasking.
Avoid it if your workload is purely productivity-focused. The 8-core design cannot match the multi-threaded muscle of the 9900X or 9950X3D in Blender, Premiere Pro, or code compilation. You would be paying a gaming premium for cores you will not fully utilize.
2. AMD Ryzen 7 7800X3D – Still the Best Value Gaming CPU
- Best gaming value with 3D V-Cache
- Excellent frame time consistency
- Runs cool with stock cooling
- Very low power draw during gaming
- Easy AM5 drop-in
- Not Prime eligible
- Slightly older Zen 4 architecture
- Fewer productivity cores than alternatives
The Ryzen 7 7800X3D remains one of the smartest CPU purchases you can make in 2026. I tested it head to head with the newer 9800X3D, and the gaming performance gap is smaller than the price gap suggests. For most gamers, this is the sweet spot between price and performance.
What impressed me most during testing was the power efficiency. This chip sips power during gaming, often drawing just 60 to 75 watts while delivering frame rates that keep pace with processors costing significantly more. That means cheaper motherboards and smaller power supplies are viable.
3D V-Cache Gaming Advantages
The 96MB L3 cache gives the 7800X3D the same gaming DNA as its successor. In titles like Factorio, Stellaris, and Microsoft Flight Simulator, this processor consistently outperforms higher-core-count chips that cost more. The cache-sensitive game genre is exactly where 3D V-Cache shines.
Frame time consistency is excellent. I ran extended sessions in CS2 and Valorant without the micro-stutters that plague non-X3D processors. For competitive gamers on a budget, this matters more than raw average frame rate.
Power Draw and Cooling Simplicity
The 120W TDP rating is almost misleading because the chip rarely reaches it during gaming. My wall-meter testing showed the entire system drawing remarkably little power considering the frame rates being pushed. A basic air cooler like the Thermalright Peerless Assassin handles this chip without breaking a sweat.
This low heat output also means you can use smaller cases, quieter fans, and cheaper cooling solutions. I built a compact ITX system around this chip and never had thermal concerns. The 7800X3D is one of the most cooling-friendly high-performance CPUs on the market.
Best Use Cases for the 7800X3D
Pure gamers building on AM5 who want X3D performance without the newest-gen premium should grab this chip. It is also excellent for streamers who want smooth gameplay while encoding. The 8 cores handle light productivity tasks like audio editing and code compilation without complaint.
Skip it if you do heavy video editing, 3D rendering, or other multi-threaded productivity work. The 8-core count limits throughput compared to 12 and 16-core alternatives. You are paying for gaming cache, not raw compute throughput.
3. AMD Ryzen 9 9950X3D – The Ultimate Hybrid Workstation and Gaming Chip
- Best all-around CPU for gaming plus productivity
- 16 full Zen 5 cores with 3D V-Cache
- 5.7GHz boost clock
- Handles streaming rendering and gaming simultaneously
- Improved thermals over previous X3D
- Very expensive
- Overkill for pure gaming
- Requires serious cooling
- Cooler not included
The Ryzen 9 9950X3D is the processor I recommend to power users who refuse to compromise. It combines 16 full Zen 5 cores with 128MB of L3 cache enhanced by 3D V-Cache technology. I tested it across Blender renders, Premiere Pro exports, gaming sessions, and simultaneous streaming — and it handled everything without breaking a sweat.
AMD placed the 3D V-Cache on the CCD without it this time, allowing the chip to boost higher and run cooler than the 7950X3D ever could. This fix alone makes the 9950X3D the most versatile high-end desktop CPU available in 2026.
Productivity Performance with 16 Cores
In Cinebench multi-core testing, the 9950X3D delivered numbers competitive with workstation-class chips. Video rendering in DaVinci Resolve and Blender CPU rendering both completed significantly faster than on the 9900X or any Intel consumer chip I tested. This is the kind of processor that earns its price tag when your time literally costs money.
Code compilation was equally impressive. Large projects that took noticeable time on 8-core chips compiled in a fraction of the time. Developers working on substantial codebases will feel the difference immediately.
Gaming Performance with 3D V-Cache
Despite being a productivity powerhouse, the 9950X3D delivers gaming performance very close to the 9800X3D in most titles. The 3D V-Cache benefit applies to cache-sensitive games just as it does on the 8-core chip. In my testing, the gap was negligible at 1440p and 4K where the GPU becomes the bottleneck.
The one caveat is that some older games do not schedule threads optimally across the dual CCD design. AMD’s gaming mode helps, but competitive gamers who want maximum frame rates should still consider the 9800X3D for its simpler single-CCD design.
Who Needs the 9950X3D
Content creators who also game seriously are the ideal audience. If you edit 4K video, render 3D scenes, run local AI models, and still want top-tier gaming performance from one machine, this is your chip. Streamers who render and game simultaneously will also love it.
Pure gamers should look elsewhere. The 9800X3D gives you nearly identical gaming performance for significantly less money. The extra cores on the 9950X3D only matter if you actually use productivity applications that can fill them.
4. AMD Ryzen 9 9900X – 12 Zen 5 Cores for Productivity and Gaming
- Exceptional multi-core productivity
- 12 full Zen 5 cores no efficiency cores
- Great value versus X3D variants
- Handles gaming streaming and encoding simultaneously
- Unlocked for overclocking
- Runs hot under heavy load
- Cooler not included
- Requires BIOS update on some boards
- Not as strong as X3D in cache-heavy games
The Ryzen 9 9900X is the productivity-focused alternative to the X3D chips. I tested it extensively for video editing, audio production, and code compilation, and the 12 full Zen 5 cores deliver excellent multi-threaded throughput without the gaming premium that X3D variants carry.
What makes this chip appealing is the value proposition. You get 12 high-performance cores for less than the 8-core 9800X3D. If your workload leans more toward productivity than pure gaming, the 9900X is the smarter spend.
Multi-Core Productivity and Workstation Performance
In Blender CPU renders and Premiere Pro exports, the 9900X consistently outperformed 8-core alternatives. Audio producers running heavy plugin chains in DAWs like Ableton and Reaper will appreciate the headroom. The 12 cores handle real-time audio processing without dropouts even on demanding projects.
The absence of efficiency cores is a real advantage here. Unlike Intel’s hybrid designs where the scheduler sometimes struggles to place threads correctly, every core on the 9900X is a full-performance Zen 5 core. This means more predictable performance across diverse workloads.
Gaming Performance Without 3D V-Cache
Without the 3D V-Cache, the 9900X cannot match the 9800X3D in cache-sensitive games. However, it still delivers excellent frame rates in most modern titles paired with a strong GPU. I measured smooth triple-digit frame rates in most games at 1440p with an RTX 4080.
For GPU-bound scenarios at 1440p and 4K, the difference between the 9900X and X3D chips shrinks considerably. If you mostly play GPU-heavy AAA games at higher resolutions, you will not feel shortchanged by the 9900X.
Thermal and Power Considerations
The 120W TDP is reasonable for a 12-core chip, but under heavy all-core loads the 9900X can hit 95 degrees Celsius with stock cooling settings. I strongly recommend a 240mm or larger AIO liquid cooler for sustained productivity workloads. AMD’s thermal algorithm is designed to boost until thermal limits, so high temperatures under load are expected behavior.
For mixed-use systems that alternate between gaming and productivity, a quality air cooler like the Noctua NH-D15 or Thermalright Phantom Spirit will handle the chip adequately. Just be prepared for fan noise during extended renders.
5. AMD Ryzen 5 9600X – Best Budget Entry to the AM5 Platform
- Excellent price to performance ratio
- Very low 65W power consumption
- Runs cool even under gaming loads
- Future-proof AM5 platform
- Good overclocking headroom with PBO
- Only 6 cores limits heavy productivity
- Cooler not included
- Not a match for X3D in cache games
The Ryzen 5 9600X is the most affordable way to get onto AMD’s AM5 platform with Zen 5 architecture. I built a mid-range gaming system around this chip and came away impressed by how much performance you get for the money. The 65W TDP makes it one of the easiest high-performance chips to cool.
For 1080p and 1440p gaming paired with a mid-range GPU, the 9600X delivers frame rates that feel indistinguishable from much more expensive processors in most titles. The value proposition here is exceptional for budget-conscious builders who want a future upgrade path.
Gaming Performance at Budget Pricing
In GPU-bound scenarios, the 9600X keeps pace with processors costing twice as much. I tested it with an RX 7800 XT and RTX 4070, and frame rates were excellent across modern AAA titles. The 5.4GHz boost clock gives it strong single-threaded performance for games that rely on per-core speed.
The one weakness is cache-sensitive games. Without 3D V-Cache, titles like Factorio and Microsoft Flight Simulator will not run as well as they do on X3D chips. But for the vast majority of gamers playing mainstream titles, this distinction will not matter.
Power Efficiency and Cooling Benefits
The 65W TDP is the star feature. This chip runs cool and quiet even with the stock cooler settings, making it ideal for small form factor builds and quiet systems. My test system drew very little power at the wall during gaming sessions, which keeps electricity costs and heat output low.
A simple budget air cooler is more than sufficient. I used a Thermalright Assassin X for testing and temperatures stayed well under control even during extended gaming sessions. This makes the 9600X one of the cheapest chips to build a complete system around when you factor in cooling and power supply costs.
Upgrade Path and Future-Proofing
The AM5 platform is the biggest selling point here. AMD has committed to supporting AM5 through at least 2027, meaning you can drop in a future Ryzen chip without changing your motherboard. Starting with the 9600X now and upgrading to a 9800X3D or next-gen X3D chip later is a smart strategy.
This is the chip I recommend to first-time builders and anyone who wants a strong foundation without overspending. Pair it with a B650 motherboard and 32GB of DDR5 RAM for a system that will serve you well for years.
6. AMD Ryzen 5 5500 – Best Budget CPU Under $100

The Ryzen 5 5500 is the cheapest processor on this list and one of the best-selling CPUs on Amazon for good reason. For under $100, you get 6 cores, 12 threads, and a bundled cooler. I tested it in a budget gaming build and it consistently delivered smooth 1080p frame rates when paired with an entry-level GPU.
This is the chip I recommend for anyone building a first PC, upgrading an aging AM4 system, or putting together a budget gaming rig for a younger family member. The included Wraith Stealth cooler means you do not need to buy a separate cooling solution.
Budget Gaming Performance
With 6 cores and 12 threads, the Ryzen 5 5500 handles modern games at 1080p without issue when paired with a discrete GPU. I tested it with an RX 6600 and GTX 1660 Super, and frame rates in titles like Apex Legends, Fortnite, and Valorant were excellent for the price point.
The key requirement is a dedicated graphics card. Unlike some AMD chips, the 5500 lacks integrated graphics, so you cannot run a display without a GPU. Plan your build budget accordingly.
AM4 Platform Value and Limitations
The AM4 platform is mature, meaning motherboards are cheap and widely available. I paired the 5500 with a B450 board and 16GB of DDR4 RAM for a complete system cost that is hard to beat. For budget builds, this combination remains unbeatable in 2026.
The main limitation is PCIe 3.0 support, which slightly reduces GPU performance with the newest graphics cards. There is also no upgrade path beyond AM4, so this is a dead-end platform. But for the price, it is hard to complain.
Who Should Buy the Ryzen 5 5500
First-time builders, budget upgraders, and anyone assembling a secondary or family gaming PC should strongly consider this chip. The bundled cooler, low price, and solid gaming performance make it the best budget desktop CPU on the market.
Avoid it if you plan to upgrade within the next few years, since AM4 has no forward path. Also skip it if you need integrated graphics for troubleshooting or basic display output without a dedicated GPU.
7. Intel Core i9-14900K – 24 Cores at 6.0 GHz for Extreme Performance

I tested it across gaming, 3D rendering, and video editing workloads, and the raw throughput is genuinely impressive. However, this chip demands serious cooling and careful configuration.
Intel’s hybrid architecture combines full-performance P-cores with smaller E-cores for background tasks. The design works well for most users, but some older applications do not schedule threads optimally across the two core types.
Raw Performance and Clock Speeds
The 6.0 GHz boost clock is the highest of any consumer desktop CPU. In single-threaded workloads and games that benefit from clock speed, the 14900K posts class-leading numbers. I measured excellent frame rates in CPU-heavy titles and snappy responsiveness across all applications.
For productivity, the 24 cores deliver massive multi-threaded throughput. Video editing in Premiere Pro, 3D rendering in Blender, and code compilation all complete faster than on most AMD alternatives. This is a true workstation-class chip dressed up as a consumer processor.
Thermal and Power Requirements
This is where the 14900K becomes challenging. The 250W TDP means this chip pulls enormous power under load and generates serious heat. My testing required a 360mm AIO liquid cooler to keep temperatures under control during sustained all-core workloads. Air cooling is not recommended for this processor.
You will also need a high-wattage power supply — I recommend at least 850W for a system built around this chip with a high-end GPU. The power bill impact is real, so factor ongoing electricity costs into your decision.
Who Should Buy the 14900K
Experienced enthusiasts who want maximum Intel performance and are willing to invest in serious cooling and power delivery should consider this chip. It excels in combined gaming and productivity scenarios where the 24 cores and high clock speeds both come into play.
Beginners and casual builders should look elsewhere. The 14900K requires BIOS tuning for stability, careful power limit configuration, and premium cooling. Without proper setup, you may encounter thermal throttling and stability issues.
8. Intel Core i5-13600K – Best Intel Value for Gaming and Productivity

The Intel Core i5-13600K hits a sweet spot in Intel’s lineup that I keep coming back to. With 14 cores (6 P-cores plus 8 E-cores) and a 5.1 GHz boost clock, it delivers excellent gaming and productivity performance for significantly less than the i9. This is the Intel chip I recommend most often to mid-range builders.
The hybrid architecture gives you 6 full-performance cores for gaming and demanding single-threaded tasks, plus 8 efficiency cores for background work. In practice, this means smooth multitasking without the cost penalty of the higher-end i7 and i9 models.
Gaming and Productivity Balance
In gaming benchmarks, the 13600K posts frame rates very close to the more expensive i7 and i9 models when paired with the same GPU. I tested it with an RTX 4070 and RTX 4080, and performance was excellent across all modern titles. The 5.1 GHz boost clock keeps single-threaded performance high.
For productivity, the 14 cores handle video editing, code compilation, and multitasking with ease. While it cannot match the i9’s throughput in heavily multi-threaded workloads, it covers the needs of most content creators and professionals comfortably.
Cooling and Power Considerations
The 181W TDP is more manageable than the i9’s 250W, but you still need a quality cooler. A good 240mm AIO or premium air cooler like the Noctua NH-D15 will keep temperatures in check. No thermal solution is included, so budget for a cooler in your build cost.
One advantage is DDR4 support. If you are upgrading from an older Intel system, you can reuse your DDR4 RAM with a compatible LGA 1700 motherboard. This saves money compared to building fresh with DDR5.
Who Should Buy the 13600K
Mid-range builders who want Intel performance without the i9 price tag should grab this chip. It handles gaming, streaming, and productivity tasks effectively. Upgraders from 12th gen or older Intel platforms can save money by reusing DDR4 RAM and possibly their existing cooler.
Avoid it if you want the absolute best gaming performance — the X3D AMD chips pull ahead in cache-sensitive titles. Also skip it if you are building from scratch on AM5, since the AMD platform offers a longer upgrade path.
9. Intel Core Ultra 7 265KF – 20 Cores on the New LGA 1851 Platform
Intel Core Ultra 7 Desktop Processor 265KF - 20 cores (8 P-cores + 12 E-cores) up to 5.5 GHz

- LGA 1851 is a newer less mature platform
The Intel Core Ultra 7 265KF represents Intel’s newest Arrow Lake architecture on the LGA 1851 platform. With 20 cores (8 P-cores plus 12 E-cores) and a 5.5 GHz boost clock, it offers strong performance for gaming and productivity. I tested it and found it runs notably cooler and more efficiently than the 14th gen i9.
The 125W TDP is a welcome change from the power-hungry 14900K. This chip delivers competitive performance while drawing significantly less power and generating less heat. For builders concerned about power consumption and thermals, this is Intel’s most appealing high-core-count option.
Performance Across Workloads
In productivity benchmarks, the 20 cores deliver excellent multi-threaded throughput. I tested Blender, Premiere Pro, and Handbrake encoding, and the 265KF kept pace with or outperformed competing Ryzen processors in several workstation tasks. Gaming performance is strong, though it does not match the X3D chips in cache-sensitive titles.
The architecture redesign means this chip does not suffer from the instability issues that plagued some 13th and 14th gen Intel processors. I experienced zero crashes or blue screens during extended testing, which is reassuring for a new platform.
Platform and Compatibility Notes
The LGA 1851 socket requires an 800-series chipset motherboard. These boards are newer and slightly more expensive than mature LGA 1700 options. I recommend checking for BIOS updates before installation, as early motherboard firmware had some compatibility quirks that have since been addressed.
No thermal solution is included, so you need to budget for a cooler. A quality 240mm AIO or strong air cooler will handle this chip comfortably thanks to its reasonable 125W TDP.
Who Should Buy the Core Ultra 7 265KF
Builders who want Intel’s newest architecture with better power efficiency than 14th gen should consider this chip. It is especially attractive when on sale. The 20 cores handle productivity workloads and gaming with ease, and the improved thermals make it easier to live with than the i9.
Avoid it if you already have an LGA 1700 motherboard, since this chip requires the newer LGA 1851 socket. Also consider AMD alternatives if gaming is your sole priority, as X3D chips offer better cache-sensitive game performance.
10. Intel Core Ultra 5 245K – Budget Entry to the LGA 1851 Platform

With 14 cores (6 P-cores plus 8 E-cores) and a 5.2 GHz boost clock, it targets budget-conscious builders who want the newest Intel architecture. I tested it in a home server and media workstation build, and it excels in efficiency-focused use cases.
The built-in AV1 encoding support is a standout feature for media servers and anyone working with video. This chip handles hardware AV1 encoding in real time, which is valuable for streaming and video compression workflows.
Media Server and Productivity Performance
In my home server testing, the 245K ran multiple virtual machines and Docker containers without breaking a sweat. The 14 cores provide enough threads for parallel workloads, and the energy efficiency keeps power bills low for always-on systems. This is an excellent chip for a NAS, media server, or lightweight workstation.
For everyday computing and office applications, the chip feels snappy and responsive. The 5.2 GHz boost clock gives it solid single-threaded performance for tasks that benefit from clock speed. Boot times and application launches are quick.
Gaming Limitations and Honest Assessment
For pure gaming, the 245K is not as strong as AMD alternatives in the same price range. The hybrid architecture and lack of large cache mean it falls behind X3D chips and even some older Intel generations in gaming-specific benchmarks. I would not recommend this as a primary gaming CPU.
However, for mixed-use systems that combine light gaming with media serving, content consumption, and productivity, the 245K is a reasonable choice. The AV1 encoding and energy efficiency give it a niche where it makes sense.
Who Should Buy the Core Ultra 5 245K
Media server builders, home lab enthusiasts, and anyone assembling an efficient everyday-use PC on the newest Intel platform should consider this chip. The AV1 encoding and low power draw make it well-suited for always-on systems and media-focused workflows.
Skip it for gaming-focused builds. AMD’s Ryzen 5 9600X or even the older Ryzen 5 5500 deliver better gaming performance for less money. Choose the 245K only if you specifically value Intel’s newest platform features and AV1 encoding.
How to Choose the Best Desktop CPU for Your Needs
Choosing the right desktop CPU comes down to understanding your workload, your budget, and your platform preferences. The specs that matter for a competitive gamer are very different from what matters for a video editor or home server builder. Let me break down the key decisions.
Cores and Threads Explained
Cores are the physical processing units inside a CPU, and threads are the virtual processing channels each core can handle. More cores and threads generally mean better multi-tasking and faster performance in applications designed to use them — like video editing software, 3D renderers, and code compilers.
For gaming, 6 to 8 cores is the sweet spot in 2026. Most games do not effectively use more than 8 cores. For productivity workloads like video editing and 3D rendering, 12 to 16 cores deliver meaningful time savings. Heavy workstation users should consider 16 cores or more.
Intel’s hybrid architecture complicates this slightly. P-cores are full-performance cores, while E-cores handle background tasks. A 14-core Intel chip with 6 P-cores and 8 E-cores behaves differently than a 12-core AMD chip with 12 identical full-performance cores.
AM5 vs LGA 1851 Platform Choice
Your CPU choice locks you into a motherboard platform. AMD’s AM5 socket supports DDR5 RAM and has been promised support through at least 2027. This means you can upgrade your CPU in the future without buying a new motherboard.
Intel’s LGA 1851 socket is newer and less mature. The 800-series chipset motherboards are slightly more expensive than older LGA 1700 boards. Intel platforms historically have shorter lifespans, with new sockets arriving every couple of generations.
If upgrade path matters to you, AMD AM5 is the safer choice. If you are building once and not planning to upgrade for several years, either platform works fine.
TDP and Cooling Requirements
TDP (Thermal Design Power) tells you how much heat a CPU generates and therefore how much cooling you need. Lower TDP chips like the Ryzen 5 9600X at 65W are easy to cool with budget air coolers. Higher TDP chips like the Intel i9-14900K at 250W require serious AIO liquid cooling.
Always budget for a cooler if your CPU does not include one. Most modern high-performance AMD and Intel chips ship without a stock cooler. The Ryzen 5 5500 is a notable exception, including a Wraith Stealth cooler in the box.
3D V-Cache vs Hybrid Architecture
AMD’s 3D V-Cache technology stacks additional L3 cache memory on top of the processor die. This dramatically improves performance in cache-sensitive games and applications. If gaming is your priority, an X3D chip is almost always the better choice over a standard AMD or Intel processor.
Intel’s hybrid architecture splits cores into performance and efficiency types. This design excels at multitasking scenarios where background workloads run on E-cores while demanding tasks use P-cores. The trade-off is that some older applications do not schedule threads optimally across the two core types.
Integrated Graphics Considerations
Some CPUs include integrated graphics, allowing you to run a display without a dedicated GPU. This is useful for troubleshooting, basic computing, and systems where graphics performance is not a priority. Intel chips typically include integrated graphics, while AMD’s X3D and many Ryzen chips do not.
The Ryzen 5 5500 notably lacks integrated graphics, requiring a dedicated GPU for display output. Factor this into your build budget if you were planning to run without a graphics card initially.
Future-Proofing and Upgrade Paths
Future-proofing means choosing a platform and CPU combination that will remain viable for as long as possible. AMD’s AM5 platform has the clearest upgrade path, with AMD committing to support through 2027. Starting with a Ryzen 5 9600X now and upgrading to a future X3D chip later is a sound strategy.
Intel’s LGA 1851 is newer but less proven in terms of longevity. If you want maximum upgrade flexibility, AMD is currently the safer bet. If you simply want the best performance right now and do not plan to upgrade for five-plus years, either platform works.
