In Renoir the power saved on the I/O die and IF links goes to graphics, so that's always gonna be a stretch either way. Couple of weeks and we'll see Here's hoping Vega won't be too much of a drag.What about 35W and 45W?
Because the uncore eats up too much power leaving almost nothing to the cpu cores. Even 8 core Epycs uses lot's of power.
I wonder why amd never released some Epyc 5000 series (TR platform based) and Epyc 3000/Opteron 3000 series (am4 platform based). It seams they have a large gap (read market) to fill in servers.
