The Comet Lake-S series isn’t a radical rethinking of Intel’s desktop lineup. Intel is offering sizable gains from Coffee Lake, but the CPUs are still fabricated on a 14nm node and aren’t as efficient as what AMD is offering in this category.

That said, the best desktop PCs all feature Intel’s CPUs, and that’s mainly because Intel has a clear edge when it comes to gaming. Intel is betting on gaming prowess as the key differentiator for the Comet Lake-S series, and we’ve already seen how well the flagship Core i9-10900K and Core i7-10700K fare in this regard.

With the Core i5-10600K, Intel is setting its sights on the $300 segment. The Core i5-10600K features a 6-core 12-thread design with a 125W TDP, and while the mid-range CPU doesn’t have the Core i9-10900K’s Thermal Velocity Boost or Turbo Boost 3.0, you get Hyper-Threading enabled this time, a big deal considering the feature was exclusive to Intel’s high-end designs.

Intel has a clear progression across the Comet Lake-S series, with the Core i9-10900K offering a 10-core 20-thread design and the Core i7-10700K switching to an 8-core 16-thread option. The Core i5-10600K sits one tier below the Core i7, and as such, it gets six cores and 12 threads.

The Core i5-10600K has a base frequency of 4.10GHz — higher than the Core i9 and i7 models — but it doesn’t quite manage to hit 5GHz in turbo. That’s understandable given Intel wants to limit that particular feature to the Core i9 and i7 variants, but seen as a whole, the Core i5-10600K ticks all the right boxes:

Category Intel Core i5-10600K
Cores/Threads 6/12
Base Frequency 4.10GHz
Turbo Boost 2.0 4.50GHz (all cores)
Turbo Boost 2.0 4.80GHz (two cores)
Integrated Graphics Intel UHD Graphics 630

Intel has eight distinct CPUs in the Comet Lake Core series and five variants across the Pentium and Celeron lines. But because Intel offers several versions of its CPUs, including unlocked designs aimed at gamers, models without integrated graphics, and low-power options, we end up with 32 unique SKUs in the Comet Lake-S launch lineup.

As a refresher, here’s what each suffix translates to:

  • K: Unlocked design with integrated graphics
  • KF: Unlocked design without integrated graphics
  • No suffix: Regular model with integrated graphics — no overclocking here
  • F: Regular model without integrated graphics
  • T: Low-power option

From the naming convention, we can make out that the Core i5-10600K is an unlocked part that includes integrated graphics — the Intel UHD Graphics 630. A significant change with Comet Lake-S is the switch to the LGA1200 socket, requiring the use of the new Z490 series motherboards. That means that if you’re using an LGA1151-based Z270 or Z390 board, you won’t be able to slot in the Core i5-10600K.

Intel is using higher frequencies to increase performance, leading to power-hungry CPUs.

Intel’s failure to switch to the 10nm node is what led to the new socket. The LGA1200 essentially has 49 additional pins to be able to deliver more power to the chipset. That’s because with Intel still retaining the 14nm node for Comet Lake-S, the only way to deliver better performance figures is by increasing the frequencies. That’s why you’ll find a noticeable uptick in base frequencies across the board with Comet Lake-S.

For instance, the Core i5-10600K has a base frequency of 4.1GHz, while last year’s i5-9600K had a more modest 3.70GHz. The
TDP has also been increased from 95W to 125W, leading to decreased energy efficiency figures from the previous generation. Intel is effectively using a 14nm++++ node with Comet Lake-S, and the one advantage here is that it is a mature process.

That said, Intel is making a few tweaks: Comet Lake-S designs use a thinner die, a thicker heat spreader, and a solder thermal interface material to improve thermal performance. You won’t find IPC gains with Comet Lake-S, with Intel focusing its attention instead on getting the maximum out of the 14nm node. By increasing the frequencies and better thermal management, it has achieved just that.

With gaming being the key differentiator for the 10th Gen Comet Lake-S series, it’s no wonder that the Core i5-10600K holds up incredibly well in this area. The Core i5-10600K goes up against the Ryzen 5 3600X and the Ryzen 7 3700X, and it manages to outmatch AMD by a significant margin when it comes to gaming.

The Core i5-10600K is the most powerful $300 CPU for gaming.

The Core i5-10600K delivers 15 to 18% better performance over the Ryzen 5 3600X for 1080p games and a 12% uptick over the Ryzen 7 3700X. What makes things that much more interesting is that the Core i5-10600K also carves out a healthy lead over the 12-core/24-thread Ryzen 9 3900X to the tune of 9%, making it the standout winner. Of course, you’ll start seeing diminishing returns as you increase the resolution to 1440p and 4K as the GPU starts playing a significant role.

It’s clear that Intel’s focus on gaming has allowed Comet Lake-S designs to eke out a lead over their AMD counterparts, and the Core i5-10600K is a fantastic choice in this category. It is on part with the Core i7-9700K and even outmatches the Core i9-9900K in a few scenarios, and the fact that you’re getting this level of performance on a $300 CPU is spectacular.

The Core i5-10600K is almost on par with the Core i9-10900K in terms of gaming performance, and there’s a minute 3% difference between the two in this area. That makes the Core i5-10600K a particularly great choice for gamers as it is available for around half the price of Intel’s flagship Core i9-10900K. If you’re primarily interested in gaming, then the Core i5-10600K is a better choice over the Core i7 or i9 designs.

Of course, the Core i5-10600K doesn’t measure up to the Ryzen 7 3700X or the Ryzen 9 3900X when it comes to multi-threaded use cases, but it is on par with the Ryzen 5 3600X in this regard. That said, it holds its own for single-threaded workloads, so for most Windows applications, you shouldn’t see a lot of difference.

But the one area where the Core i5-10600K falls short is power consumption. With Intel effectively relying on higher frequencies to deliver better performance, the CPU is power-hungry. The 7nm Ryzen alternatives fare much better in this regard, but having said that, the Core i5-10600K has plenty of headroom for overclocking down the road.

AMD made huge inroads into the value segment over the last two years with its Ryzen designs, and the $208 Ryzen 5 3600X is a standout in this segment. The Ryzen 5 3600X debuted for $250 but is now selling for $208. The CPU has six cores and 12 threads — just like the Core i5-10600K — and it delivers better energy efficiency and slots into AMD’s existing AM4 platform. You also get a cooler in the box, and while the Ryzen doesn’t come close to the Core i5-10600K when it comes to gaming, it is a great value.

Then there’s the $300 Ryzen 7 3700X. AMD’s 8-core/16-thread CPU is an excellent option in this category, and it is particularly great for multi-threaded workloads. Like the Ryzen 5 3600X, it loses out to the Core i5-10600K in terms of gaming performance, but overall you’re getting pretty stellar value here.
