Clock Speeds

Starting with the clock speeds, we can see that both CPUs have the same base clock speeds for both the P-cores and E-cores. However, they differ slightly in terms of boost clock speeds.

Specifically, the Core i9-12900KS supports a boost frequency of 5.2 GHz for the P-cores, while the i7-13700K betters that with 5.3 GHz. Similarly, for the E-cores, the Core i9-12900KS has a boost clock frequency of 4.0 GHz, and the Core i7-13700K pushes that up to 4.20 GHz

L2 Cache

The Raptor Lake Core i7s get an upgrade to 4MB of L2 cache per E-core cluster. With each cluster having 4 cores and 2 clusters in total, we get 8MB of L2 cache from the E cores. The Core i9-12900KS contains 2MB of L2 cache for every 4 E cores. Thus, the Core i7-13700K features 30MB of L2 cache, compared to 24MB of the Core i9-12900KS.

Memory Support

Both CPUs support DDR4 and DDR5 memory. However, the Core i7-13700K supports DDR5 memory with transfer rates as high as 5400 MT/s. The Core i9-12900KS only supports up to 4800 MT/s of transfer speeds. 

This also means that the Core i7-13700KS supports faster memory bandwidth, at 89.6 GB/s, compared to 76.8 GB/s of the Core i9-12900KS.

Thermal Performance

The i7-13700K was the more power-efficient CPU, but is it also more thermally efficient? Let’s see. 

A graph comparing the thermal performance of the Core i9-12900KS vs the Core i7-13700K across 7 benchmarks.
Thermal Performance – Image Credits (Tech4Gamers)
  • So in terms of temperatures, the i9-12900KS averaged 65.1°C across the 6 benchmarked games. In comparison, the i7-13700K ran slightly cooler, at 64.5°C
  • The Core i7-13700K is, therefore, not even 1% better than the Core i9-12900KS in terms of thermal performance when it comes to 1080P gaming. 

Pricing 

Since the Core i9-12900KS costs almost half of its launch MSRP now (around $419), it’s evenly matched with the i7-13700K (~$417) in terms of CPU prices. Furthermore, both CPUs support the same chipsets, so the question of platform costs does not come into consideration. 

The two CPUs also share very similar power draw ratings. However, the Core i7-13700K is the more efficient CPU at a base frequency and could be slightly more economical if you’re running your CPU at stock settings.

In our 1080P gaming performance analysis, we found that the Core i7-13700K was 7.1% more power-efficient than the i9-12900KS. But, since the i7-13700K has a slightly higher boost TDP rating, it could cost more if your focus is on 4K gaming or productivity tasks.
