Intel 13th Gen Raptor Lake Desktop CPU Platform Details Leaked: More Cores, More Cache, DDR5-5600 Support But Missing PCIe Gen 5 M.2

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

Intel’s Core i9-13900K Raptor Lake is an average of 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 24-core, 32-thread QS sample in an 8 P-Core, 16 E-Core configuration. The CPU has a total of 36MB L3 cache and 32MB L2 cache for a total of 68MB smart cache. It also comes with a base (PL1) TDP of 125W and an MTP of around 250W.

This chip runs at the same 3.0 GHz base and 5.5 GHz boost clocks that we’ve seen in previous benchmarks from the same leaker. The final chip is expected to hit single-core boost clocks of up to 5.7-5.8 GHz, but that remains to be seen until the final variant is launched.

In terms of performance, we have more detailed gaming and synthetic benchmarks with Intel Core i9-13900K (5.5GHz) and Core i9-12900K (4.9GHz) running at their stock frequencies on a Z690 platform with 32GB DDR5 -6400 memory running 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 increase comes from the increased cache as it overcomes a 50% increase (68MB vs 44MB).

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

Gaming performance was tested in various titles at 2160p, 1440p, and 1080p resolutions. The average performance boost across all three resolutions appears to be around 5-10% for the Intel Core i9-13900K Raptor Lake CPU compared to its Core i9-12900K Alder Lake predecessors. There are few instances where the chip showed huge wins. The cache and higher clock speeds seem to really benefit the minimum framerate with jumps of around 25-30% in some titles 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, where not only did the average performance increase with its additional 3D V-Cache, but the minimum FPS numbers also increased significantly thanks to the increased cache. Notably, the Ryzen 7 5800X3D offered a much larger cache size compared to the Raptor Lake cache bump (compared to Alder Lake CPUs).

Intel Core i9-13900K vs Core i9-12900K Full Gaming Benchmark Performance Breakdown:

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

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

As for 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 Resolutions Min Average: 20.86% faster

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

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

Below are all of these results as compiled by @Harukaze5719:

Breaking down the power consumption numbers 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
  • Intel Core i9-13900K vs Core i9-12900K at 1440p: 19.8% 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 the previously leaked benchmarks. Overall, it looks like the CPU will be faster than the Ryzen 9 7950X on workload-specific tasks, while being on par in gaming benchmarks. But with AMD releasing its Ryzen 7000 3D V-Cache chips later this year, based on the same Zen 4 core architecture, if they manage to take it from Zen 4, Intel’s gaming crown will be short-lived be.

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