Limitless Core i9-13900K examined
Over at Bilibili, one can discover a complete evaluation of a retail model of the Core i9-13900K processor, the flagship Raptor Lake desktop CPU this is supposedly popping out subsequent month.
The evaluation is a collaboration between ECSM_Official and OneRaichu, and it’s divided into a couple of portions. Naturally, we received’t destroy the whole lot right here, and we inspire readers to peer the whole evaluation for themselves.
Formally, Intel is to announce a brand new collection of desktop processors on September twenty seventh on the Innovation tournament. The timing for critiques continues to be unconfirmed, however we’re most definitely nonetheless a couple of weeks clear of legitimate thirteenth Gen Core/Z790 checks. Subsequently, this analysis is most probably the nearest we get to one thing that is regarded as a evaluation at this degree.
The reviewers if truth be told did have get admission to to Intel Z790 motherboard and checks have been made. Then again, the ones are beneath embargo and weren’t shared but (their evaluation shall be up to date as soon as NDA ends). As loopy as it’s going to sound, their i9-13900K checks don’t seem to be beneath embargo, possibly for the reason that CPU was once sourced with out Intel’s lend a hand and an older Z690 motherboard was once used.
The CPU was once in comparison to Core i9-12900KF Alder Lake CPU operating with both DDR5-6000 CL30 or DDR4-3600 CL17 reminiscence. The machine was once additionally provided with NZXT Kraken X73 AIO cooler, whilst ASRock Z690 motherboard Taichi Razer Version was once up to date to the newest 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 Speed Spice up) and as much as 5.5 GHz with 3 to 8 cores. Via comparability, i9-12900K has 5.2 GHz and 4.9 GHz max frequencies for a similar choice of lively cores.
Raptor Lake CPU helps sooner JEDEC DDR5 reminiscence spec via default (5600 MT/s) whilst Alder Lake was once ‘restricted’ to 4800 MT/s. Naturally, each CPUs reinforce DDR4 requirements and each can use overclocked reminiscence.
We can soar proper into efficiency analysis and go away reminiscence, core-to-core latency and throughput take a look at so that you can test. ECMS is making plans two checks with i9-13900K: with limitless energy and with locked PL2 mode to 253W. The section with ‘legitimate’ PL2 shall be shared later.
In Cinebench R23 checks, Core i9-13900K is quicker via 13% with Efficiency (Raptor Cove) cores in comparison to 12900K (Golden Cove). Curiously, even the efficiency of the Environment friendly cores has higher via 14%, even if the similar structure is used (Gracemont). It’s value noting that now not simplest has the frequency higher for Raptor Lake CPUs but additionally the dimensions of the L3 cache. ECSM confirms that with limitless energy i9-13900K can wreck 40K issues in Cinebench R23, which is 47% upper than 12900K with uncapped energy.
In some other fashionable take a look at, CPU-Z, the i9-13900K rankings 945 and 16877 issues in unmarried and multi-threaded checks. That’s 14.5% and 49% higher efficiency than Alder Lake CPU respectively.
On reasonable, the limitless i9-13900K is 41.78% sooner than 12900K. Relying at the take a look at, which would possibly or would possibly not get pleasure from upper multi-threaded efficiency, the uplift varies from 0.33% to 76.72% over Alder Lake.
The reviewer concluded that i9-13900K brings 10% upper framerates than 12900K in CPU-bound video games (CSGO, Ashes of the Singularity), but additionally improves body occasions for the slowest 0.1% frames. Under is CSGO efficiency with limitless i9-13900K and i9-12900K operating with DDR5 and DDR4 reminiscence:
ECSM is to offer extra take a look at effects later: with default PL2 restrict and in a while Z790 motherboard. The realization is that i9-13900K has 12% higher single-threaded efficiency and multi-threaded ‘very much progressed to compete with AMD Zen4’.
Many due to Alienxzy for the end!
