    Great review.
    The problem that amd has to raise frequencies, what is it due to?
    Architecture, silicon, tsmc ...

    It's likely 99% TSMC. We see that usually there is only 1-2 cores in each 8-core chiplet that can hit higher clocks. Those good cores are hitting decently high clocks. This is all pointing at TSMC's process which is very immature in the grand scheme of things. I would expect the 7nm+ process to help raise clocks by around 15% partly because the new process is 15% more efficient but also because TSMC should be applying lessons learned to its new tweaked 7nm node which is similar to what Intel has done with 14nm+.

    15% sounds really good, hopefully.
    4100 mhz * 15% = 615mhz
    4715mhz for 6/8 cores would be great but who knows where they can improve.

    Increase in clocks doesnt necessarily translate into equivalent increase in performance. Look at the benchmarks. About 10% higher base clock over 3700x, yet only about 2-3% performance gain in most benches.
