Intel's microcode update 0x129 dropped in an attempt to correct the unmitigated disaster that has become of Intel's 13th- and 14th-gen CPUs. While Intel initially claimed that the microcode update wouldn't affect performance at all, some multithreaded benchmark scores show as much as a 22% performance loss. Fortunately, gaming is unaffected by the update…..
In Cinebench, the unlocked Core i9's score dropped a whopping 9,123 points from 39,783 to 30,660 points — or 22.9%…..
