We always review multiple CPUs at once to compare data, using consistent components for fair testing where possible.

We use a mix of both synthetic and in-game benchmarks to gauge performance, while also considering additional features and pricing.

We also measure the likes of power consumption and peak temperature under stress to get an idea of performance efficiency.

Intel Core i9-14900K

Most powerful Intel processor


  • Impressive gaming performance
  • Versatile across multiple fields
  • APO could be a game changer
  • No price increase compared to last gen


  • Insane temperatures & power draw
  • Far better value CPUs available
  • Little difference compared to last gen

The Intel Core i9-14900K is the most powerful consumer desktop processor you can currently buy, from Intel or any other processor manufacturer. This should come as no surprise to anyone looking at the specs sheet, with the chip packing 24 cores, 32 threads and 6GHz peak clock speeds. 

Our benchmark scores back up these impressive performance claims, with the Intel Core i9-14900K posting higher scores than all of the competition. This was the case for both synthetic benchmarks and in-game tests, showcasing that this desktop chip excels at pretty much everything. 

That said, the performance jump isn’t significant compared to the last-gen Intel Core i9-13900K, but that’s not really an issue considering both chips are priced the same. 

What’s more, the Intel Core i9-14900K will play nice with the latest RAM and SSDs thanks to support for DDR5 and PCIe 5.0. So if you’re looking to build the most powerful PC possible, then the Intel Core i9-14900K is undoubtedly the best pick.

Intel Core i5-14600K

Best value Intel processor


  • Strong performance in game
  • Best value processor right now
  • Reasonable temps and power draw
  • Price remains the same as last gen


  • No major hardware advancement
  • Better professional picks elsewhere
  • Lacks Intel’s APO tech

The Intel Core i5-14600K may not be quite as powerful as its i9 sibling, but it’s not far behind in terms of performance considering its more affordable price. The chip features 14 cores, 20 threads and is capable of up to a 5.3GHz boosted clock speed. 

Despite its modest specs, it offers outstanding gaming performance, easily outperforming the AMD Ryzen 7 7700X and AMD Ryzen 5 7600X in every single game on test. In fact, we’d wager that you’ll struggle to find a better gaming performance from a desktop CPU for less than the £300/$300 price point. 

Of course, the constrained core count does limit the multi-core performance compared to the i9, but it’s certainly no slouch for the likes of content creation, making it a fantastic all-rounder chip. 

Lastly, the Intel Core i5-14600K offers support for both PCIe 5.0 and DDR5, which means you can build a PC with all of the latest and greatest components. So if you want to build (or upgrade) a cutting-edge PC without breaking the bank, this is our top recommendation.

Intel Core i5-12600K

Best value for gamers 


  • Excellent gaming performance
  • Huge improvements to multi-core performance
  • Future-proofed with PCIe 5.0 and DDR5
  • Great power efficiency


  • Teething issues for game compatibility
  • Requirement of Z690 motherboard drives up cost

We’re jumping back a couple of generations for this one, but we think the Intel Core i5-12600K still represents outstanding value if gaming is your top priority for your next PC build. 

With just 10 cores and 16 threads, it’s seriously lagging behind its newer siblings in terms of multi-core performance, which means it’s probably not the best option for creatives that deal with 4K video edits and complex 3D animations. 

But if you’re sticking to gaming, the Intel Core i5-12600K proves to be a more affordable alternative to the Intel Core i5-14600K. Not only were the gaming results excellent, but it also proved to be highly efficient in our benchmark tests, so won’t send your energy bills spiralling out of control. 

Best of all, the Intel Core i5-12600K supports DDR5 and PCIe 5.0, allowing you to build a cutting-edge gaming PC. And with the Intel Core i5-12600K being so cheap, you’ll be able to spend more money on the likes of a graphics card to give gaming performance a serious push.

Intel Core i5-11600K

Best budget Intel processor 


  • Excellent gaming performance
  • Support for PCIe 4.0
  • Good value for money
  • Runs at comparatively low temperatures


  • Poor multi-threaded performance
  • Marginal performance gains from 10th generation

The Intel Core i5-11600K launched back in 2021, making it one of the oldest CPU options in this best Intel processor list. But it still packs a powerful performance for gamers thanks to its 4.9GHz max clock speed, especially when you consider the bargain-friedly price.  

It aced our gaming benchmark tests, punching above its weight by remaining competitive with the Intel Core i9-11900K and AMD Ryzen 7 5800X. It runs impressively cool under stress too, ensuring a consistent performance that doesn’t need an ultra-expensive cooling system. 

There are some caveats by going this cheap, with the 6-core and 12-thread counts highlighting its limitations for multi-threaded workloads – creators may want to stay clear as a result. Support is limited to DDR4 memory and PCIe SSDs too, lowering the ceiling of potential upgrades for your gaming PC.

But if you simply want a cheap-as-chips gaming PC, the Intel Core i5-11600K remains an excellent option with a surprisingly strong performance given its age and low cost.

What is PCIe?

PCIe (peripheral component interconnect express) is an interface standard used for connecting high-speed components such as GPUs and SSDs. The PCIe generation will determine the performance handicap for connected components. The latest standard, PCIe 5.0, currently doesn’t have a big impact on GPU performance, but can enable far faster SSD speeds with compatible hardware.

What is the best CPU type for gaming?

The best thing to look out for when buying a gaming CPU is single-core performance. However, it’s also worth considering other aspects such as supported features, power consumption and temperature.
