Continuing the tradition of Qualification Sample benchmarks, today, we have a yet another new video from “Extreme Player“, over on Bilibili, who has tested both the Core i7-13700Kand Core i5-13600K QS across a variety of different games and benchmarks. As always, the CPUs were pitted against their current-gen counterparts and the video itself was discovered by renowned leaker HXL (@9550pro).
This time, the test bench is a little different than before. It consists of two ASRock Z690 Steel Legend motherboards (DDR4 and DDR5 version). On the motherboards, we see 32GB of DDR5-5200 and 32GB of DDR4-3600 memory from Team Group. The power supply in question is the CoolerMaster Silent Pro M2 1500W across both systems. Same is the case with the GPU, which is a MSI GeForce RTX 3090 Ti.
Before we move to the benchmarks, it’s important to keep in mind that these are Qualification Samples (QS), which means the final retail products might slightly differ in terms of performance and thermal output. Still, the discrepancy is close enough to base our expectations off of these SKUs.
In terms of synthetic performance, both the i5-13600K and i7-13700K comfortably beat their predecessors: the Core i5-12600K and Core i7-12700K(F). Extreme Player did separate tests for DDR4 and DDR5 memory, which makes the charts very complicated to evaluate. Take a look for yourself:
Essentially, the inclusion of DDR5 memory barely makes a difference in synthetic benchmarks for the Core i7-13700K against the i7-12700KF. We only see a noticeable bump in performance in FireStrike Extreme Physics and Time Spy Extreme CPU. In FireStrike Physics, the DDR4 test bench actually takes the edge, which further tells us that the need for DDR5 memory is fully-developed yet.
This notion is reinstated with the Core i5-13600K benchmarks even more. The Raptor Lake SKU performs almost identically with DDR5 and DDR4 memory, with only TimeSpy CPU and FireStrike being the outliers. So, just for the sake of relevancy, we are going to take the DDR5 scores in consideration to make the comparisons easier.
All in all, against the i5-12600K, the i5-13600K performs about 11.4% faster in the 3DMark benchmark suite. As for the Core i7-13700K, it is roughly 8.5% faster than the Core i5-12700KF across the same benchmarks. The increase in core-counts across both CPUs is likely to be blamed for this improvement in performance.
For the gaming benchmarks, we’re going to be using @haruzake5719‘s redone charts as Extreme Player’s own charts are extremely detailed and focusing on purely one type of memory is far more readable. Haruzake took the DDR4 results from all four CPUs and put them inside two charts, taking the total game average at each resolution into account.
Here’s how both Core i7s perform against each other:
As you can see, the largest difference is seen at 1080p resolution, where the game is most CPU-bound. Moving up the ladder, in 4K the gap closes down significantly. Taking the average frame-rate analysis into consideration, the Core i7-13700K produces 7.4% more FPS than its predecessor at 1080p. In comparison, at 4K resolution, the same CPU is only 2.68% faster.
The biggest difference in gaming performance for both SKUs is actually experienced in the minimum FPS produced at 1080p, where the 13700K is a remarkable 13.67% faster than its current-gen counterpart. Likewise, 1440p is where we see the least noticeable difference of about only 5.1%, which is still impressive nonetheless.
Moving on the Core i5-13600K, taking a look at the chart below, we can see a similar picture being painted here. However, the most sizable gap in this comparison is at 1440p resolution where the maximum FPS of the 13600K is about 12.9% higher than the Core i5-12600K.
On average, the CPU is about 10% faster at 1080p, but only a shocking 1.5% faster at 4K resolution. Interestingly enough, if you look at the 4K minimum frame rates, the 13600K pulls ahead by 11.27% which means this chip is far more stable than the 12600K. At 1440p resolution, the chip performs 3.7% better than the former.
Taking everything into account, the Core i5-13700K is about 8% faster than the Core i5-12700KF. Whereas, the Core i5-13600K is about 7.4% faster than the Core i5-12600K. So, the performance uplift is surprisingly similar, but keep in mind that this average was calculated using DDR4 scores; DDR5 memory will likely widen the gap further.
Update: Haruzake has provided charts for gaming performance compiled with DDR5 results, as you can see below. Across all resolutions, Core i5-13600K is 6.16% faster on average, compared to the i5-12600K. On the other hand, the Core i7-13700K is 5.33% faster than the i7-12700K(F) on average.

Coming back to my initial comment about increase core counts on these CPUs, let’s take a quick look at the main specifications of both SKUs. But before that, here’s the recap on how the 13th Gen chips compare to their 12th Gen counterparts in terms of their gaming chops, across all resolutions:
- Core i7-13700K vs. Core i7-12700K Average: 5.33% Faster
- Core i7-13700K vs. Core i7-12700K Minimum FPS: 11.82% Faster
- Core i7-13700K vs. Core i7-12700K Maximum FPS: 8.06% Faster
- Core i5-13600K vs. Core i5-12600K Average: 6.16% Faster
- Core i5-13600K vs. Core i5-12600K Minimum FPS: 12.40% Faster
- Core i5-13600K vs. Core i5-12600K Maximum FPS: 7.78% Faster
The Core i7-13700K is a 16-core CPU with 8 Performance Cores and 8 Efficiency Cores. Those P-Cores can boost up to 5.4GHz with a maximum reported power consumption of 244W which was observed in a previous leaked benchmark. It’s currently being speculated that the 13700K will have a 50W higher power limit than the 12700K. It’s also important to note that the 12700K(F) is a 12-core (8P+4E) CPU, not a 16-core one.
As for the Core i5-13600K, this CPU also gets treated to a 4-core bump in its configuration, going from 10-cores on the 12600K to 14-cores on the 13600K. Out of those 14, there are 6 Performance Cores and 8 Efficiency Cores. This chip has a maximum boost clock of 5.2GHz and could have a 180W power limit, which is around 30W higher than its predecessor.
Both Raptor Lake SKUs also have higher cache counts, which certainly helped in the gaming department. Compared to the i5-12600K’s measly 20MB of total “Game” cache, the 13600K offers 44MB. Whereas, the i7-13700K’s 54MB cache trumps i7-12700K(F)’s 25MB cache.
Higher core counts lead to better performance and more heat, that’s a foregone conclusion. What’s interesting is how these new Raptor Lake processors will stack up against AMD‘s highly-anticipated Ryzen 7000 series based on the new Zen4 architecture. AMD is also bringing forth a new platform, Socket AM5, which is said to take a massive leap over the current AM4 platform.
If Intel can price its new CPUs just right and release them close to AMD’s own launch, which is rumored to be in September, there is a real chance for some fierce head-to-head competition here. This is the first time in many years where both companies have been so ferocious in their approach to delivering the best silicon possible, and only time will tell who truly prevails in the end.
