Just like some Intel processors this year, some people have been sold online before the official release. According to VideoCardz reports, the Core i5-12400 processor has appeared on eBay recently. Most of the S-Spec code used is QXDY, which is an engineering sample (ES), but it is not consistent with the QYHX version tested by the French website Comptoir Hardware.
Unreleased Intel Core i5-12400 samples have been sold on eBay
Normally, consumers will not be able to buy the Core i5-12400 processor until Intel is officially released early next year. It is positioned in the mid-range market and only contains 6 Performance Cores based on the Golden Cove architecture, and is not equipped with Efficient Cores based on the Gracemont architecture.
There are also differences between the turbo frequency and the set display. The QXDY version has a turbo frequency of 4.4 GHz and the iGPU is UHD770, but the QYHX version has a turbo frequency of 4.0 GHz and the iGPU is UHD730. It is speculated that the version coded as QYHX may also be a Core i5-12600 processor or be modified on its basis.
Intel has shipped tens of thousands of engineering samples to its partners for testing. The goal is to find out the chip’s problems and continue to repair them. At present, many Z690 motherboards in the retail market do not support early engineering samples, because different codes are required, and generally only support the ARC version (QS) and the retail version. If the user buys these leaked engineering samples, it is likely to be unusable.
