Intel Core i9-13900K Raptor Lake CPU Gaming and synthetic performance benchmarks leaked, 5% faster on average than Core i9-12900K

The first gaming and synthetic performance benchmarks of Intel’s Core i9-13900K Raptor Lake 5.5GHz CPU have been leaked by Extreme Player on Bilibili (via HXL).

Intel’s Core i9-13900K Raptor Lake averages 5% faster than Core i9-12900K Alder Lake in leaked gaming benchmarks

The Intel Core i9-13900K Raptor Lake CPU tested in the leaked benchmarks is a QS sample with 24 cores and 32 threads in an 8 P-Core and 16 E-Core configuration. The CPU has a total of 36 MB L3 cache and 32 MB L2 cache for a combined 68 MB ‘Smart Cache’. It also comes with a base (PL1) TDP of 125W and an MTP of about 250W.

This chip runs around the same 3.0GHz base and 5.5GHz boost clocks that we saw in previous benchmarks from the same leaker. The latter chip is expected to hit single-core boost clocks up to 5.7-5.8GHz, but that remains to be seen until the latest variant hits the market.

In terms of performance, we have more detailed gaming and synthetic benchmarks with the Intel Core i9-13900K (5.5 GHz) and Core i9-12900K (4.9 GHz) running at their native frequencies on a Z690 platform with 32 GB DDR5-6400 memory and a GeForce RTX 3090 Ti graphics card. The Core i9-13900K already has a 12.2% clock speed advantage over the Core i9-12900K, so it should be faster by default, even if the architecture is the same. The additional improvement comes from the increased cache as it bumps more than 50% (68MB vs 44MB).

Intel Raptor Lake Core i9-13900K vs Alder Lake Core i9-12900K synthetic benchmarks (via Extreme Player):

Game performance has been tested in several titles with resolutions of 2160p, 1440p and 1080p. The average performance boost appears to be about 5-10% across all three resolutions for the Intel Core i9-13900K Raptor Lake CPU versus its Core i9-12900K Alder Lake predecessors. There are only a few instances where the chip showed huge gains. The cache and higher clocks really seem to benefit from the minimum frame rate with about 25-30% jumps in a few titles like PUBG, Forza Horizon 5 and up to 70-80% gains in Red Dead Redemption 2.

The same was the case with the AMD Ryzen 7 5800X3D, which not only saw average performance increase with its additional 3D V-Cache, but minimum FPS numbers also went up quite a bit thanks to the increased cache. Notably, the Ryzen 7 5800X3D offered a much larger cache size compared to the Raptor Lake cache bump (versus Alder Lake CPUs).

  • Intel Core i9-13900K vs Core i9-12900K All Res Avg – 4.83% faster

As for the minimum FPS, the breakdown at each resolution is as follows:

  • Intel Core i9-13900K vs Core i9-12900K at 1080p: 27.93% faster minimum FPS
  • Intel Core i9-13900K vs Core i9-12900K at 1440p: 21.83% faster minimum FPS
  • Intel Core i9-13900K vs Core i9-12900K at 2160p: 12.82% faster minimum FPS
  • Intel Core i9-13900K vs Core i9-12900K All Res Min Avg: 20.86% faster

And finally, we have the maximum FPS breakdown for each resolution as listed below:

  • Intel Core i9-13900K vs Core i9-12900K at 1080p: 6.29% faster maximum FPS
  • Intel Core i9-13900K vs Core i9-12900K at 1440p: 4.42% faster maximum FPS
  • Intel Core i9-13900K vs Core i9-12900K at 2160p: 2.58% faster maximum FPS
  • Intel Core i9-13900K vs Core i9-12900K All Res Max Avg: 4.43% faster

Following are all these results as compiled by @Harukaze5719:

Breaking down the power consumption figures for each resolution tested, we get the following results for the Intel Core i9-13900K vs. Core i9-12900K:

  • Intel Core i9-13900K vs Core i9-12900K at 1080p: 19.1% higher power consumption

The Intel Core i9-13900K delivered on average about 10% faster single-threaded and 35% faster multi-threaded performance compared to the Core i9-12900K in the previously leaked benchmarks. Overall, it looks like the CPU will be faster than the Ryzen 9 7950X in workload-specific tasks, while on par with gaming benchmarks. But with AMD releasing its Ryzen 7000 3D V-Cache chips based on the same Zen 4 core architecture later this year, Intel’s gaming crown, if they manage to grab it from Zen 4, will be short-lived.

The Intel 13th Gen Raptor Lake desktop CPUs, including the flagship Core i9-13900K, are expected to launch in October on the Z790 platform. The CPUs will be up against AMD’s Ryzen 7000 CPU lineup, which will also launch in Fall 2022.
