Some puzzling screenshots were posted online by a Chinese netizen who claimed they were from a computer running an Intel Core i5-13600K processor. This allegedly mid-range overclocker-friendly CPU may offer enthusiasts an unbeatable price/performance combo, according to an enthusiastic Citizen’s Bilibili article.
In CPU-Z (1T and nT tests), the chip outperforms AMD’s Ryzen 9 5950X, and Cinebench R23 multi-core benchmarks show it to be only 7 or 8% slower.
The Raptor Lake chip under consideration, according to the post, is an ES3 (engineering sample, third version), but it is set up with QS (qualifying sample) clocks. Enthusiastic Citizen claims to have a real QS chip as well but says it is “too early” to publish benchmark results since he needs to wait for Intel and its board partners to make additional improvements.
The Intel Core i5-13600K is said to have 20 processing threads distributed between 6 Performance and 8 Efficiency cores, an all-core turbo frequency of 5.1 GHz, and 24MB of L3 cache. Unfortunately, the tester found that this processor consumed up to 173W at 1.31V, with “room for optimization.”
An enthusiastic Citizen hypothesizes that the Intel Core i5-13600K may be hindered by a BIOS problem.
No screenshots of the motherboard are shown, however it is suggested that the “early Z790” motherboard may be to blame for the surprisingly low Cinebench R23 single-threaded score. Perhaps an efficiency core was exploited by the software as a basic mistake on unidentified silicon for this test.
Even after excluding the Cinebench 23 single-threaded results, the multi-threaded results are still highly impressive and roughly 30% quicker than the previous version. Additionally, the AMD Ryzen 9 5950X and it have performance disparities in the single-digit percentage range.
Since there doesn’t appear to be a “BIOS issue” present, CPU-Z ratings may be easier to understand. In this synthetic test, the Raptor Lake chip has the highest single-thread scores, while its multi-threaded test result is competitive with the original Alder Lake flagship (i9-12900K).
