Unlimited Core i9-13900K examined
Over at Bilibili, one can discover a complete review of a retail model of the Core i9-13900K processor, the flagship Raptor Lake desktop CPU that’s supposedly popping out subsequent month.
The review is a collaboration between ECSM_Official and OneRaichu, and it’s divided into a number of components. Naturally, we cannot spoil every little thing right here, and we encourage readers to see the total review for themselves.
Officially, Intel is to announce a brand new collection of desktop processors on September twenty seventh on the Innovation occasion. The timing for critiques remains to be unconfirmed, however we’re in all probability nonetheless a number of weeks away from official thirteenth Gen Core/Z790 exams. Therefore, this analysis might be the closest we get to one thing that’s thought-about a review at this stage.
The reviewers really did have entry to the Intel Z790 motherboard and exams had been made. However, these are below embargo and weren’t shared but (their review will likely be up to date as soon as NDA ends). As loopy as it could sound, their i9-13900K exams usually are not below embargo, presumably as a result of the CPU was sourced with out Intel’s assist and an older Z690 motherboard was used.
The CPU was in comparison with Core i9-12900KF Alder Lake CPU working with both DDR5-6000 CL30 or DDR4-3600 CL17 reminiscence. The system was additionally geared up with NZXT Kraken X73 AIO cooler, whereas ASRock Z690 motherboard Taichi Razer Edition was up to date to the most recent 12.01 BIOS.
Intel i9-13900K has extra environment friendly cores than 12900K and better clocks. The CPU boosts as much as 5.8 GHz with as much as 2 cores (Thermal Velocity Boost) and as much as 5.5 GHz with 3 to eight cores. By comparability, i9-12900K has 5.2 GHz and 4.9 GHz max frequencies for a similar quantity of energetic cores.
Raptor Lake CPU helps sooner JEDEC DDR5 reminiscence spec by default (5600 MT/s) whereas Alder Lake was ‘restricted’ to 4800 MT/s. Naturally, each CPUs assist DDR4 requirements and each can use overclocked reminiscence.
We will soar proper into efficiency analysis and go away reminiscence, core-to-core latency and throughput check so that you can verify. ECMS is planning two exams with i9-13900K: with limitless energy and with locked PL2 mode to 253W. The half with ‘official’ PL2 will likely be shared later.
In Cinebench R23 exams, Core i9-13900K is quicker by 13% with Performance (Raptor Cove) cores in comparison with 12900K (Golden Cove). Interestingly, even the efficiency of the Efficient cores has elevated by 14%, though the identical structure is used (Gracemont). It is value noting that not solely has the frequency elevated for Raptor Lake CPUs but additionally the scale of the L3 cache. ECSM confirms that with limitless energy i9-13900K can break 40K factors in Cinebench R23, which is 47% larger than 12900K with uncapped energy.
In one other widespread check, CPU-Z, the i9-13900K scores 945 and 16877 factors in single and multi-threaded exams. That’s 14.5% and 49% higher efficiency than Alder Lake CPU respectively.
On common, the limitless i9-13900K is 41.78% sooner than 12900K. Depending on the check, which can or might not profit from larger multi-threaded efficiency, the uplift varies from 0.33% to 76.72% over Alder Lake.
The reviewer concluded that i9-13900K brings 10% larger framerates than 12900K in CPU-bound video games (CSGO, Ashes of the Singularity), but additionally improves body instances for the slowest 0.1% frames. Below is CSGO efficiency with limitless i9-13900K and i9-12900K working with DDR5 and DDR4 reminiscence:
ECSM is to offer extra check outcomes later: with default PL2 restrict and afterward Z790 motherboard. The conclusion is that i9-13900K has 12% higher single-threaded efficiency and multi-threaded ‘enormously improved to compete with AMD Zen4’.
Many because of Alienxzy for the tip!
