Rocket Lake Redux: 0x34 Microcode Offers Small Performance Gains on Core i7-11700K One of the leading questions as to our original Core i7-11700K review was the validity of those results given that, as usual with launches, motherboard vendors push BIOS updates as we move closer to the official launch. At the time, we were testing on Intel’s microcode 0x2C, the latest version available to the motherboard vendor. Intel has since released microcode 0x34, and we have retested our results on this new update.
