THE SOURCE FOR TECH BUYING ADVICE
Core i5-13600K offers an impressive multi-core showing in leaked benchmarks. Another leak of test data for Intel’s Raptor Lake has recently surfaced, but unlike previous leaks, this one concerns a mid-range model from the company’s next lineup of next-generation CPUs rather than the flagship 13th-gen processor.
To be more explicit, what we’re seeing here is allegedly benchmarking data for the Intel Core i5-13600K, a CPU that many purchasers would pick since it’s less expensive than Core i7 or i9 CPUs.
The leak was spotted by VideoCardz and is another affair which has been shared via Bilibili in China, this time courtesy of Enthusiastic Citizen. The claim is that the 13600K processor in question is an ES3 or Engineering Sample 3, meaning it’s a later stage pre-release chip.
Enthusiastic Citizen asserts, however, that because the ES3 CPU is operating at the same clock speeds as a QS or Qualification Sample – or, to put it another way, the pre-release models, which are essentially the finished version, sent out to Intel’s partners for testing – it should provide a good indication of final performance (arm yourself with a very distinct sense of skepticism when considering all this, of course).
This implies that although the engineering sample’s performance cores did run at 4.9GHz to 5.1GHz boost, Enthusiastic Citizen increased it to 5.1GHz across all cores to simulate the final product (efficiency cores were also boosted from 3.9GHz to 4GHz, too).
In case you’d forgotten, the Core i5-13600K is thought to have six performance cores and eight efficiency ones, meaning it’s a 14-core chip in total (with 20-threads, as only the performance cores have hyper-threading).
The benchmarking was carried out in CPU-Z and Cinebench, and in the former, the 13600K hit 830 points for single-core and 10,031 points in multi-core, which is respectively 8% and 79% faster than its predecessor, the current 12600K.
Regarding Cinebench R23, the 13600K scores 1,387 single-core points and 24,420 multi-core points. This is shockingly 40 percent faster for multi-core than the 12600K, but the single-core figure is horribly off because the Raptor Lake chip is actually 26 percent slower.
Analysis: A lot of caveats, but nonetheless looking promising for Intel
The first Cinebench result is plainly strange; a next-generation CPU should not be 26 percent slower than the processor it is replacing. This serves as a warning that benchmarking pre-release silicon is fraught with dangers, particularly when an engineering chip has been enhanced to match the frequency of a qualifying sample.
However, the other findings presented here do align somewhat with our expectations. Seeing a 40% increase in multi-core performance is really astounding, and it perfectly matches another leak where the Core i9-13900K flagship also attained this same 40% generational leap, which gives the information offered here a little more weight.
It’s a good sign to see such predicted performance gains for a mid-range Raptor Lake CPU, and we can certainly expect better multi-core performance from 13th-gen chips given that Intel is purportedly really ramping up the overall core count by doubling up on efficiency cores in the 13600K (and 13900K).
However, these early leaks are also pointing to power usage being bumped up with Raptor Lake, and Enthusiastic Citizen theorizes that the 13600K could run with a 160W TDP (not a world of difference to the 150W of the 12600K, but a bit of a step up nonetheless).
The dramatic spike in leakage surrounding Raptor Lake sample CPUs, which is what is frequently observed in the lead-up to the debut of a new generation of silicon, is one of the most interesting things to see right now. Theoretically after a launch ceremony in late September, Intel’s 13th-gen processors are expected to arrive early in October. The constant stream of Raptor Lake leakage now flowing hints that this will be the case.
The key question is therefore whether AMD will be able to launch Ryzen 7000 before Intel does, since current speculation has it that both next-generation CPU lines will be on sale in September at around the same time. If this leak is accurate, AMD may be in for a tough battle in the mid-range market, therefore Team Red can’t really afford to release Zen 4 late.
