Intel Core i5-12400 Engineering Samples Surface on eBay, Riddled with Compatibility Issues

A rather big chunk of Intel Core i5-12400 "Alder Lake" engineering samples (ES) hit eBay. The i5-12400 is an upcoming mid-range processor Intel is planning to release in Q1-2022. The 6-core/12-thread processor only features 6 "Golden Cove" performance cores, and lacks Efficiency cores (which is probably a good thing for gamers). Each of the six cores has 1.25 MB of L2 cache, while they share an 18 MB L3 cache.

VideoCardz warns that the ES chips out in the wild could be riddled with compatibility issues with Z690 motherboards that are in the market. Apparently, there are two revisions of i5-12400 unreleased doing rounds, C0 and B0, with the former being a QS or qualification sample, and the latter an ES or engineering sample. The two differ in maximum boost frequency4.40 GHz vs. 4.00 GHz. They also differ with S-SPEC codes of QXDY and QYHX. Even with production versions of firmware and Intel ME, retail Z690 motherboards don't seem to guarantee compatibility with these samples. You are probably better off waiting for retail versions of these chips.
