Unlimited Core i9-13900K tested

Over astatine Bilibili, 1 tin find a broad reappraisal of a retail mentation of the Core i9-13900K processor, the flagship Raptor Lake desktop CPU that is supposedly coming retired adjacent month.

The reappraisal is simply a collaboration betwixt ECSM_Official and OneRaichu, and it is divided into fewer parts. Naturally, we won’t spoil everything here, and we promote readers to spot the afloat reappraisal by themselves.

Officially, Intel is to denote a caller bid of desktop processors connected September 27th astatine the Innovation event. The timing for reviews is inactive unconfirmed, but we are astir apt inactive a fewer weeks distant from authoritative 13th Gen Core/Z790 tests. Therefore, this valuation is apt the closest we get to thing that beryllium considered a reappraisal astatine this stage.

The reviewers really did person entree to Intel Z790 motherboard and tests were made. However, those are nether embargo and were not shared yet (their reappraisal volition beryllium updated erstwhile NDA ends). As brainsick arsenic it whitethorn sound, their i9-13900K tests are not nether embargo, presumably due to the fact that the CPU was sourced without Intel assistance and an older Z690 motherboard was used.

The CPU was compared to Core i9-12900KF Alder Lake CPU moving with either DDR5-6000 CL30 oregon DDR4-3600 CL17 memory. The strategy was besides equipped with NZXT Kraken X73 AIO cooler, portion ASRock Z690 motherboard Taichi Razer Edition was updated to the latest 12.01 BIOS.

Intel i9-13900K has much Efficient cores than 12900K and higher clocks. The CPU boosts up to 5.8 GHz with up to 2 cores (Thermal Velocity Boost) and up to 5.5 GHz with 3 to 8 cores. In comparison, i9-12900K has 5.2 GHz and 4.9 GHz max frequencies for the aforesaid fig of progressive cores.

Raptor Lake CPU supports faster JEDEC DDR5 representation spec by default (5600 MT/s) portion Alder Lake was ‘limited’ to 4800 MT/s. Naturally, some CPUs supports DDR4 modular and some tin usage overclocked memory.

We volition leap close into show valuation and permission memory, core-to-core latency and throughput trial for you to check. ECMS is readying 2 tests with i9-13900K: with unlimited powerfulness and with locked PL2 mode to 253W. The portion with ‘official’ PL2 volition beryllium shared later.

In Cinebench R23 tests, Core i9-13900K is faster by 13% with Performance (Raptor Cove) cores compared to 12900K (Golden Cove). Interestingly, adjacent the show of the Efficient cores has accrued by 14%, though the aforesaid architecture is utilized (Gracemont). It is worthy noting that not lone the frequence has been accrued for Raptor Lake CPUs, but besides the size of the L3 cache has. ECSM confirms that with unlimited i9-13900K tin interruption 40K points successful Cinebench R23, which is 47% higher than 12900K with uncapped power.

In different fashionable test, CPU-Z, the i9-13900K scores 945 and 16877 points successful azygous and multi-threaded tests. That’s 14.5% and 49% amended show than Alder Lake CPU respectively.

On average, the unlimited the i9-13900K is 41.78% faster than 12900K. Depending connected a test, which whitethorn oregon whitethorn not payment from higher multi-threaded performance, the uplift varies from 0.33% to 76.72% implicit Alder Lake.

The reviewer concluded that i9-13900K brings 10% higher framerates than 12900K successful CPU-bound games (CSGO, Ashes of the Singularity), but besides improves framework times for the slowest 0.1% frames. Below is CSGO show with unlimited i9-13900K and i912900K moving with DDR5 and DDR4 memory:

ECSM is to supply much trial results later: with default PL2 bounds and aboriginal connected Z790 motherboard. The decision is that i9-13900K has 12% amended single-threaded show and multi-threaded ‘greatly improved to vie with AMD Zen4’.
