Intel’s next flagship processor should have no problem breaking the 5 GHz barrier a little beyond what’s already been demonstrated in the Alder Lake series, according to new leaks shared by Lordzzz, a member of the Chiphell forums who has posted not only a clear photo of an early 13th Gen Intel Core i9-13900K chip, but also some CPU-Z screenshots that tease the SKU’s configuration, including some claims regarding the performance of a more recent, better engineering sample. Intel’s Raptor Lake flagship will purportedly be able to boost up to at least 5.3 GHz through all of its Performance cores, a slight but welcome improvement over the Core i9-12900KS, which lists 5.2 GHz (P-cores) and 4 GHz (E-cores) under its max turbo frequency specifications. The Core i9-13900K engineering sample can also boost to 5.5 GHz under a single core, matching the Core i9-12900KS. Intel is expected to launch its first Raptor Lake processors by October.

The first version of the CPU that is now available on Chinese black market, is relatively old and has some limitations. Contrary to what the seller had said in the description for the processor that went on sale yesterday, the ES1 silicon has limited overclocking capability. This is not the case with ES3 silicon though, to which Lordzzz has now access to.

A screenshot was provided featuring ES1 silicon in action. The built-in benchmark into CPU-Z software shows 611 and 13015 points in single and multi-threaded tests. The sample supposedly boosts up to 4.5 GHz. One can notice that the sample has 125W TDP (so it’s the K-series variant) and no AVX-512 support.
