They might also be more energy efficient which I think is the most relevant advantage Intel has against their competitors. So I don't really get the impression that the new chips don't perform well.
Spectre probably knocked of Intels performance advantage, but is CPU performance really our current bottleneck?
Still the topic that would interest me most compared to CPU performance.
Intel keeps doing these paper launches and early announcements meant to keep them a little in the spotlight. They're not having a good time for a while now. Some websites take it with a gran of salt, some still don't, even after being repeatedly used to tout a nonexistent horn.
this is what my computers have to say about that :
Also, most ram here is not taken by the build process but by firefox tabs & a windows VM.
Because transistors have a capacitance that one has to drive, higher frequency requires more voltage and more voltage means bigger leakage currents which means more heat and power consumption.
