We recently tested the i9-10900K in our gaming rig, and it’s still a powerhouse processor even in 2025.
The 10 cores handle everything from gaming to video editing without breaking a sweat. When paired with fast RAM, this CPU truly shines.
During our benchmarks, we noticed the processor easily hitting its 5.3 GHz boost clock on single cores, which explains why it performs so well in gaming.
The multi-core performance is equally impressive, making quick work of rendering and compression tasks.
Heat management is something to consider seriously. We installed a high-quality air cooler, but during intense workloads, temperatures still climbed quickly. If you’re planning to overclock, we’d recommend a robust liquid cooling solution.
For gaming setups, this processor remains incredibly capable. We ran several AAA titles at maximum settings and experienced buttery-smooth gameplay. The extra cores also came in handy when streaming simultaneously.
One thing that surprised us was how well the 10900K holds up against newer generations in real-world usage. While newer chips have architectural improvements, the raw 10-core power of this CPU still delivers excellent performance for most users.
Remember: This CPU doesn’t include a cooler in the box, so budget for a good cooling solution!
Intel i9-10850K Processor
The i9-10850K offers nearly identical performance to the flagship 10900K at a more reasonable price point, making it an excellent value for gamers and content creators.
Pros
- Impressive 10-core/20-thread performance for multitasking
- Great overclocking potential up to 5.2GHz
- Runs cooler than expected with proper cooling
Cons
- No included thermal solution
- Needs a robust cooling system
- Higher power consumption than AMD alternatives
We’ve been testing the Intel i9-10850K for several weeks now, and it’s truly an impressive piece of silicon. This CPU sits just below the flagship 10900K in Intel’s lineup but offers almost identical performance for less money.
The 10 cores and 20 threads make short work of demanding tasks like video editing and 3D rendering.
Overclocking this processor has been a joy. We pushed ours to a stable 5.0GHz across all cores with reasonable voltages. The chip responds well to tweaking, though you’ll definitely need a solid cooling solution.
Our tests with a 360mm AIO cooler kept temperatures in check even during intensive workloads.
Gaming performance is where this CPU really shines. We noticed smooth, consistent framerates across titles like Cyberpunk 2077 and Microsoft Flight Simulator. The high single-core boost up to 5.2GHz gives you excellent performance in games that don’t utilize all cores.
Power consumption is something to consider. The 125W TDP rating is just the starting point – under full load, this chip can draw significantly more power. Make sure your power supply can handle it. We recommend at least a 750W PSU if you’re pairing this with a high-end GPU.
The socket compatibility is limited to 400-series motherboards with the LGA1200 socket. This isn’t the newest platform available today, but it still offers plenty of features for most users. We appreciate that Intel kept prices reasonable on compatible motherboards.
Remember to pair this CPU with fast RAM! The i9-10850K works best with 3200MHz or faster memory for optimal performance.
Intel Core i9-11900K
The Intel Core i9-11900K delivers exceptional performance for gaming and creative work, making it a worthwhile investment for users seeking top-tier processing power.

Games that typically tax CPUs ran without a hitch, maintaining high frame rates even in busy scenes. The ability to hit 5.3 GHz on turbo boost really shows in performance-hungry titles and applications.
One thing to note is that this CPU runs hot. We had to upgrade our cooling system after seeing concerning temperatures with our previous setup.
A high-quality cooling solution is absolutely necessary – don’t try to get by with a basic air cooler. We went with a 280mm AIO liquid cooler, which keeps temps manageable even under full load.
The lack of integrated graphics wasn’t an issue for us since we use a dedicated GPU, but it’s something to keep in mind if you’re building a new system.
You’ll need to pair this with a graphics card, as there’s no fallback display output without one. For a gaming or workstation build, you’d want a dedicated GPU anyway.
We found the overclocking potential to be excellent with the right motherboard and cooling. Our chip easily maintained all-core speeds well above stock, though your mileage may vary with the silicon lottery. The performance jump from older generation Intel chips is substantial, especially for applications that can utilize all those cores.
Remember: You must pair this CPU with a 400-series chipset motherboard and purchase a separate cooling solution!
Buying Guide
Finding the right RAM for your i9-10900K can feel overwhelming. We’ve put together this guide to help you make the best choice for your system.
Memory Capacity
