First Intel Core i9-13900K ‘Raptor Lake’ CPU review appears for retail

Tested Unlimited Core i9-13900K

in more than BilibiliOne can find a comprehensive review of the retail version of the Core i9-13900K processor, the flagship Raptor Lake desktop CPU which is supposed to release next month.

The review is a collaboration between ECSM_Official And the Raichu one, which is divided into a few parts. Of course, we won’t spoil everything here, and encourage readers to see the full review for themselves.

Officially, Intel will announce a new series of desktop processors on September 27 at the Innovation event. The timing of the reviews is still uncertain, but we are probably still a few weeks away from the official 13th generation / Z790 tests. Therefore, this rating is probably the closest thing to something that can be considered a review at this point.

Reviewers already had access to the Intel Z790 motherboard and the tests were done. However, these are subject to blocking and have not yet been shared (their review will be updated once the non-disclosure agreement expires). It may sound crazy, but their i9-13900K tests aren’t subject to blocking, presumably because the CPU was obtained without Intel’s help and using an older Z690 motherboard.

The CPU was compared to a Core i9-12900KF Alder Lake CPU running either DDR5-6000 CL30 or DDR4-3600 CL17. The system is also equipped with an NZXT Kraken X73 AIO cooler, while the ASRock Z690 Taichi Razer Edition motherboard has been updated to the latest 12.01 BIOS.

The Intel i9-13900K has more efficient cores than the 12900K and higher clocks. The CPU boosts up to 5.8GHz with up to 2 cores (Thermal Overclocker) and up to 5.5GHz with 3 to 8 cores. In contrast, the i9-12900K has frequencies of 5.2 GHz and a maximum of 4.9 GHz for the same number of active cores.

The Raptor Lake CPU supports the faster JEDEC DDR5 memory specification by default (5600 MB/s) while Alder Lake was “limited” to 4800 MB/s. Naturally, both CPUs support the DDR4 standard and both can use overclocked memory.

We’ll go straight to performance evaluation and leave memory and response time from kernel to kernel and throughput testing for you to check. ECMS plans to run two tests with the i9-13900K: with unlimited power and locked PL2 mode up to 253W. The part containing PL2 “official” will be shared later.

In our Cinebench R23 tests, the Core i9-13900K is 13% faster with Performance cores (Raptor Cove) than the 12900K (Golden Cove). Interestingly, even the performance of effective cores increased by 14%, despite using the same architecture (Gracemont). It is worth noting that not only the frequency of the Raptor Lake CPUs has been increased, but the L3 cache size has also been increased. ECSM confirms that with the Unlimited i9-13900K, it can break 40,000 points in the Cinebench R23, which is 47% higher than the 12,900K with Unlimited Power.

In another popular test, CPU-Z, the i9-13900K scored 945 and 16,877 points in both the single and multi-threaded tests. This is 14.5% and 49% better performance than the Alder Lake CPU, respectively.

On average, the unlimited i9-13900K is 41.78% faster than the 12900K. Depending on the test, which may or may not benefit from higher multi-threaded performance, the elevation ranges from 0.33% to 76.72% over Lake Alder.

The reviewer concluded that the i9-13900K fetches 10% higher frames than 12900K in CPU-bound games (CSGO, Ashes of the Singularity), but also improves frame times for the slowest 0.1% frames. Below is the CSGO performance with the i9-13900K and i912900K unlimited running with DDR5 and DDR4 memory:

ECSM will provide more test results later: with the default PL2 limit and the Z790 motherboard later. The conclusion is that the i9-13900K has 12% better single-threaded performance and multi-threaded “significantly improved to compete with AMD Zen4”.
