Intel’s Core i9-13900K 5.5GHz Raptor Lake Desktop CPU has been benchmarked at Geekbench 5 and supersedes the Core i9-12900K & Ryzen 9 5950X.
Intel Core i9-13900K 5.5GHz Raptor Lake CPU up to 48% faster than Ryzen 9 5950X in multi-threaded, 7% faster than Core i9-12900K in single-core tests
The Intel Core i9-13900K CPU is still an early sample with 24 cores and 32 threads in an 8 P-Core and 16 E-Core configuration. From earlier rumors, we can expect up to 68MB of total “game” cache on this chip. The sample tested here has a base clock of 3.0 GHz and a boost clock of 5.5 GHz. It was stated that ES3 samples go up to 5.5GHz while final CPU samples will reach speeds of up to 5.8GHz (single core). The Geekbench data log shows that the chip was already running at single-core speeds of up to 5.7GHz as shown below:
CPU tested on ASUS ROG Maximus Z690 Extreme motherboard with 32GB DDR5-6400 memory. This is a really fast DRAM configuration that was used in the tests and Raptor Lake will officially support native speeds of up to DDR5-5600.
In terms of performance, the Intel Core i9-13900K Raptor Lake CPU sample scored 2,133 points in the single-core and 23,701 points in the multi-threaded tests. For comparison, in the same benchmark, the Intel Core i9-12900K (Alder Lake) scored 1987 single-core and 17,272 points in the multi-core while the AMD Ryzen 9 5950X scored 1686 points in the single-core and 16,508 points in the multi-core tests.

This means that the new flagship is up to 48% faster than the Ryzen 9 5950X and 37% faster than the Core i9-12900K in multi-threaded tests, which is a huge leap. The addition of 8 additional electronic cores certainly helps the chip to outperform its predecessor by a large margin. When getting to single-core performance, since the Raptor Cove and Gracemont cores aren’t a big architecture lever, most of the performance improvement comes from clock speeds on single-threaded tasks. The i9-13900K still maintained a good 7% gain over the 12900K and 27% over the 5950X on single-threaded tasks.
Again, these are not the final clock speeds, so the final performance is expected to be higher from this leak. At 5.8GHz, we can expect a 10% single-core improvement and a 40% multi-core improvement over the Core i9-12900K processor. It should also mean a 50% increase in multi-threaded CPU performance over the 5950X. AMD on the other hand said that Zen 4 increases multi-threaded performance by 35% over Zen 3 so it will be an exciting battle for sure.
