The three new processors, the AMD EPYC 7F32 (8 cores), EPYC 7F52 (16 cores) and EPYC 7F72 (24 cores), expand 2nd Gen AMD EPYC performance leadership into workloads that can leverage up to 500 MHz of additional base frequency, and large amounts of cache, making AMD EPYC the world's highest per core performance x86 server CPU.
So, I don't know much about this stuff, but I've heard that there's a tradeoff between power, performance, and area.
This leads me to wonder -- if AMD (or anybody else) really wanted to focus on single thread performance, what if they held area constant at, say, Sandybridge density and then put the pedal to the metal in terms of power and performance. What frequency could be achieved?
furthermore... suppose one were to design a heterogenous CPU with one or two cores running hot, fast, and low-density with another 16 or so cores running slow, cool, and high density? Is there a reason nobody is trying that?
