Intel Core i9-13900K Raptor Lake CPU Gaming & Synthetic Performance Benchmarks Leaked, 5% Faster Than Core i9-12900K On Average

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 5% Faster Than Core i9-12900K Alder Lake on Average In Leaked Gaming Benchmarks

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

This chip is running around the same 3.0 GHz base and 5.5 GHz boost clocks that we saw in the previous benchmarks by the same leaker. The final chip is expected to hit single-core boost clocks of up to 5.7-5.8 GHz though that remains to be seen till the final variant makes it to 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 stock frequencies on a Z690 platform with 32 GB of 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 extra uplift comes from the increased cache as it gets over a 50% bump (68 MB vs 44 MB).

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

The gaming performance was tested in various titles at 2160p, 1440p, and 1080p resolutions. The average performance improvement seems to be around 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 cases where the chip showed huge gains. The cache and higher clocks really seem to be benefitting the minimum frame rate with around 25-30% jumps in a few titles such as 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 go up with its extra 3D V-Cache but the minimum FPS numbers also went up quite a bit thanks to the increased cache. Notably, the Ryzen 7 5800X3D offered a much bigger cache size compared to the Raptor Lake cache bump (vs Alder Lake CPUs).

The Intel Core i9-13900K delivered around 10% faster single-threaded and 35% faster multi-thread performance on average versus 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 being on par in 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 is expected to launch in October on the Z790 platform. The CPUs will be going up against AMD's Ryzen 7000 CPU lineup which also launches in Fall 2022.
