Intel's 13th Gen Core i5 "Raptor Lake" desktop processor lineup could see the top Core i5-13600K and i5-13600KF feature a 6P+8E core-configuration (that's six performance cores and eight efficiency cores). Each of the six P-cores has HyperThreading enabled, making this a 14-core/20-thread processor. Each of the six "Raptor Cove" P-cores has 2 MB of dedicated L2 cache. The eight "Gracemont" E-cores are spread across two E-core clusters with four cores, each. Each cluster shares 4 MB of L2 cache among the four E-cores (increased from 2 MB per cluster on "Alder Lake"). The P-cores and E-cores share 24 MB of L3 cache, increased from 20 MB on the i5-12600K.

A qualification sample (QS) of the Core i5-13600K made its way to social media, where it was put through a bunch of synthetic tests. In CPU-Z Bench, the i5-13600K QS scores 830 points in single-thread, compared to 648 points of the Ryzen 9 5950X "Zen 3," and trails it in the multi-threaded tests, with 10031.8 points, compared to 11906 points for the Ryzen. The QS comes with a Processor Base Power (PBP) value of 125 W, same as that of the i5-12600K. "Raptor Lake" is backwards compatible with Intel 600-series chipset motherboards, although it launches alongside the Intel 700-series chipset. It shares the LGA1700 socket with 12th Gen "Alder Lake," and is built on the same Intel 7 node (10 nm Enhanced SuperFin) as its predecessor.
