True, is there any of those TR and EPYCs based on Zen 2? Any chance of trying to perform a usage test based on same clocks? EPYCs having so much lanes will have them consume more power than TRWhile I have 7 threadrippers, and 5 EPYC chips, there is no way I am going to even attempt to delid any one of them.
I would say that for the same reason that Ryzen 3000 I/O chip is built on 12nm, Higher memory clock(cant recall from where I read that) thus higher performanceReally it doesn't make sense for TR to have a different IO chip. Part of what made TR work is the fact that it was a low cost solution to enter the HDET market for AMD. Its using the exact same configuration as EPYC and while it is using less PCIe and memory controllers there is no way that AMD is making enough of these to offset the design costs for a more limited IO chip. TR also gives AMD a place to put defective IO dies where memory channels or PCIe controllers are bad.
