"The M8 is clocked to 5GHz, topping the M7's 4.13GHz. The latest generation processor has a 32KB L1 instruction cache, where the M7 has 16KB. The M8 has a 128KB L2 data cache per core, whereas the M7 has 256KB per core pair. Clearly, Oracle has figured its CPU needs a larger fast code cache near the execution engines and a rejig of the room at the back for stuff like program variables. The M8 can also issue up to four instructions at a time, compared to the dual-issue M7. This is about what you'd expect from a server-grade chip in 2017. […] Both are 20nm parts fabricated by TSMC"
Both TSMC and AMD have 5 GHz experience. So expect no less. Intel will have fierce competition from here — even if they manage to salvage 10nm and reach high frequencies matching 14nm++.
