First Review of Intel Core i9-13900K Retail Processor “Raptor Lake” Arrives

Unlimited Core i9-13900K tested

On Bilibili, you can find an extensive review of the retail version of the Core i9-13900K processor, Raptor Lake’s flagship desktop processor, which is rumored to be out next month.

The review was created thanks to the cooperation of ECSM_Official and One Raichuand is divided into several parts. Of course, we won’t spoil everything here, and we encourage readers to read the full review for themselves.

Intel officially unveils the new series of desktop processors on September 27 at the Innovation event. The time for reviews is still unconfirmed, but we are probably still weeks away from the official 13th-gen Core / Z790 testing. Therefore, this rating is probably the closest to what could be considered a review at this stage.

The reviewers actually had access to the Intel Z790 motherboard and tests were done. However, they are embargoed and not yet released (their review will be updated when the NDA expires). As crazy as it may sound, their i9-13900K testing is not embargoed, possibly because the CPU was purchased without Intel’s help and an older Z690 motherboard was used.

The processor was compared to a Core i9-12900KF Alder Lake processor with DDR5-6000 CL30 or DDR4-3600 CL17 memory. The system was also equipped with an NZXT Kraken X73 AIO cooling, and the ASRock Z690 Taichi Razer Edition motherboard was updated to the latest BIOS 12.01.

The Intel i9-13900K has more efficient cores than 12900K and higher clocks. The processor accelerates to 5.8 GHz with up to 2 cores (Thermal Velocity Boost) and up to 5.5 GHz with 3 to 8 cores. By comparison, the i9-12900K has maximum frequencies of 5.2 GHz and 4.9 GHz for the same number of active cores.

The Raptor Lake processor supports the faster JEDEC DDR5 memory specification (5600 MT / s) by default, while Alder Lake was “limited” to 4800 MT / s. Of course, both processors support the DDR4 standard, and both can benefit from an overclocked memory.

We’ll go straight to the performance evaluation and leave the memory, inter-core latency, and bandwidth test to check. ECMS plans two tests with the i9-13900K: unlimited power and blocked PL2 mode up to 253W. The part with the “official” PL2 will be available later.

In tests, the Cinebench R23 Core i9-13900K is 13% faster with Performance Cores (Raptor Cove) compared to 12900K (Golden Cove). Interestingly, even the efficiency of the Efficient cores increased by 14%, although the same architecture (Gracemont) was used. It is worth noting that not only the frequency has been increased for Raptor Lake CPUs, but also the size of the L3 cache. The ECSM confirms that with the i9-13900K unlimited it can break 40K points in the Cinebench R23, which is 47% more than 12900K with unlimited power.

In another popular test, CPU-Z, the i9-13900K scored 945 and 16,877 on single and multi-threaded tests. That’s 14.5% and 49% better than Alder Lake processors, respectively.

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

The reviewer concluded that the i9-13900K delivers 10% higher FPS than 12900K in CPU-based games (CSGO, Ashes of the Singularity), but also improves the slowest frame rate by 0.1%. Below is CSGO performance with unlimited i9-13900K and i912900K processors with DDR5 and DDR4 memory:

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