The first gaming and synthetic benchmarks of the 5.5GHz Intel Core i9-13900K Raptor Lake processor have been posted by Extreme Player at Bilibili (via HXL).

Intel Core i9-13900K Raptor Lake is 5% faster than Core i9-12900K Alder Lake on average in leaked gaming benchmarks

The Intel Core i9-13900K Raptor Lake processor tested in the leaked benchmarks is a QS sample that has 24 cores and 32 threads in a configuration of 8 P cores and 16 E cores. The CPU contains a total of 36 MB of L3 cache and 32 MB of L2 cache, for a total of 68 MB of “smart cache”. It also comes with a base (PL1) TDP of 125W and an MTP of around 250W.

This chip runs at the same 3.0GHz and 5.5GHz clock speeds we saw in previous tests from the same source. The latest chip is expected to run at single-core clock speeds up to 5.7-5.8GHz, though that remains to be seen until the final variant hits the market.

In terms of performance, we have more detailed gaming and synthetic tests with Intel Core i9-13900K (5.5GHz) and Core i9-12900K (4.9GHz) running at their stock frequencies on a Z690 platform with 32GB of DDR5 memory -6400. 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 though the architecture is the same. The additional gain is due to the increase in cache as it exceeds 50% (68 MB vs 44 MB).

Synthetic tests of Intel Raptor Lake Core i9-13900K and Alder Lake Core i9-12900K (via Extreme Player):

Gaming performance has been tested in various games at 2160p, 1440p and 1080p. The average performance improvement of the Intel Core i9-13900K Raptor Lake processor seems to be around 5-10% at all three resolutions compared to its Core i9-12900K Alder Lake predecessors. There are only a few cases where the chip showed huge winnings. Cache and higher clock speeds seem to really benefit from minimum frame rates, with jumps of around 25-30% in a few games like PUBG, Forza Horizon 5, and up to 70-80% in Red Dead Redemption 2.

The same was the case with the AMD Ryzen 7 5800X3D, which not only saw an increase in average performance thanks to the additional 3D V-Cache, but the minimum FPS also increased slightly thanks to the increased cache. Notably, the Ryzen 7 5800X3D offers a much larger cache size compared to Raptor Lake cache (compared to Alder Lake processors).

Performance comparison of Intel Core i9-13900K and Core i9-12900K in full gaming test:

One interesting comparison that has been made is in power consumption figures, where the Intel Core i9-13900K consumes up to 52% more power in games than the Core i9-12900K and averages 20% higher power consumption across all three resolutions tested. This means that the next generation Raptor Lake processor lineup will be more power hungry than Alder Lake, even in games. The breakdown of the average FPS for each resolution is as follows:

  • Intel Core i9-13900K vs. Core i9-12900K at 1080p: 4.22% higher performance on average
  • Intel Core i9-13900K vs. Core i9-12900K at 1440p: 6.97% higher performance on average
  • Intel Core i9-13900K vs. Core i9-12900K at 2160p: 3.30% higher performance on average
  • Intel Core i9-13900K vs Core i9-12900K All Res Avg – 4.83% faster

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

  • Intel Core i9-13900K vs. Core i9-12900K at 1080p: Minimum FPS 27.93% faster
  • Intel Core i9-13900K vs. Core i9-12900K at 1440p: Minimum FPS 21.83% faster
  • Intel Core i9-13900K vs. Core i9-12900K at 2160p: 12.82% faster minimum FPS
  • Intel Core i9-13900K vs. Core i9-12900K for all resolutions, min. mean: 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: Max FPS 6.29% faster
  • Intel Core i9-13900K vs. Core i9-12900K at 1440p: Max FPS 4.42% faster
  • Intel Core i9-13900K vs. Core i9-12900K at 2160p: Max FPS 2.58% faster
  • Intel Core i9-13900K vs Core i9-12900K All Res Max Avg: 4.43% faster

Below are all these results compiled by @Harukase5719:

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

  • Intel Core i9-13900K vs. Core i9-12900K at 1080p: 19.1% higher power consumption
  • Intel Core i9-13900K vs. Core i9-12900K at 1440p: 19.8% higher power consumption
  • Intel Core i9-13900K vs. Core i9-12900K at 1440p: 26.2% higher power consumption

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

Intel’s 13th Gen Raptor Lake desktop processors, including the flagship Core i9-13900K, are expected to launch in October on the Z790 platform. The processors will compete with AMD’s Ryzen 7000 line of processors, which will also launch in Fall 2022.
