Regular HotHardware readers and common {hardware} fanatics most likely already know this, however SiSoftware is the creator and maintainer of the SANDRA utility for Windows PCs. Originally created as a software to easily seize and show system info (as Windows’ personal capabilities in that regard have been fairly primitive when SANDRA was new), SANDRA is now primarily used as a benchmark suite.

Usually, checks carried out utilizing SANDRA get uploaded to SiSoftware’s database where of us can peruse the outcomes and evaluate them towards different checks. What this finally means is that the developer has entry to an incredible database of benchmark outcomes for {hardware} outdated and new. Sometimes, these outcomes embody checks carried out on pre-release {hardware}, as you have little question seen reported many instances on this very web site.

Well, SiSoft put up an article this morning doing a little evaluation of the specs and efficiency of pre-release Intel Raptor Lake CPUs, particularly the mannequin most probably to finish up being known as “Core i9-13900.” This chip is the flagship “non-K” mannequin of the Raptor Lake household, having the complete core configuration, however working at a way more conservative energy restrict than the unlocked “K” sequence CPUs.

Most of the leaked specs match the specs we have seen in prior leaks. The preliminary CPUs have eight Raptor Cove P-cores with 2MB of L2 cache, in addition to 4 clusters of “Gracemont” E-cores that share 4MB of L2 cache per cluster. That’s a major improve in L2 cache (230%) in comparison with Alder Lake.

SiSoftware marks down a peak clock price of three.7 GHz for the P-cores on the purported Core i9-13900, whereas the E-cores prime out at 2.76 GHz. The former is probably going down to those being pre-release processors, however the latter lower-clocked E-cores could be meant to enhance the little cores’ effectivity.

As we talked about, SANDRA is essentially used for benchmarking as of late. When testing CPUs, it performs a sequence of tightly-optimized arithmetic operations and gauges their efficiency at these duties. While artificial benchmarks like these aren’t essentially indicative of real-world efficiency, they nonetheless give us an attention-grabbing peek into the potential capabilities of those processors.

The “Arithmetic Native” chart right here measures integer and floating level math efficiency with particular knowledge varieties. These check do not make use of SIMD, so there is no SSE or AVX magic happening right here; these are as primary because it will get. You could be shocked to study that lots of purposes nonetheless use these sorts of directions, so this efficiency is not irrelevant in any respect.

Notably, these checks are extraordinarily multi-threaded, and that is why we see the Ryzen 9 5900X and its 12 large cores competing with the faster-on-a-single-thread Intel chips. The Core i9-11900K additionally will get to flex its high-TDP muscle, however not one of the challengers can stand as much as Raptor Lake. Even with what’s presumably diminished clock charges as a consequence of being an early pattern, the unreleased CPU dominates in each class, beating the 65W Core i9-12900 by double within the Whetstone double-precision check.

This chart is basically the identical check, however utilizing every chip’s quickest SIMD directions. That means AVX2 on all the things apart from the Core i9-11900K, which might make the most of unlocked AVX-512 assist to permit it to hold with the twelve-, sixteen-, and 24-core chips within the comparability.

Unsurprisingly, AMD’s chip wins a lot of the benchmarks right here with its twelve full-power cores. RPL typically beats Alder Lake by a handful of proportion factors, though it loses to the Twelfth-gen chip in INT32, and each thirteenth and Twelfth-gen components fall behind Rocket Lake in INT32 and INT128 testing. Of course, the truth that RPL is usually profitable towards previous-generation components regardless of a major clock price benefit bodes properly for the efficiency of ultimate silicon.
SiSoftware has since taken down the article. You can nonetheless discover it over right here on the WayBack Machine for now, although.
