Only the part that does not care about extra memory, massive IO (3X as many usable CPU IO lanes as AM4), or a 12C24T+ AM4 CPU potentially being heavily bottlenecked by dual-channel DDR4 in anything beyond workloads with modest memory traffic. From what few TR memory performance scaling benchmarks I could find, it looks like TR 1950X suffers 20-50% performance penalties between 2x3200MT/s and 4x3200MT/s. Unless AMD pulled memory bandwidth miracles with Zen 2 (no doubt UMA will be of huge help in some TR1/2 worst cases), we'll need DDR5-4000 and up to get decent all-around performance out of dual-channel 16C32T.
IMO, for most people and workloads TR4 is really intended for, AM4 is a non-starter.
