Great twitter link, but I don't see how these patents point to 4x FMAC of Zen2 at all.I saw this on another forum. This guy on twitter apparently is listing new AMD patents that belong to Zen 3/RDNA2.
The guy that posted this on the other forum said that Zen 3 will be able to do based on this patent dump:
4x FP Mul+Add
Compared to Zen 2:
2xFP Mul+Add + 2x FPadd
If they band together cores (BD style) in order to go SMT4 on the FPU side (while remaining SMT2 on integer side) then a maximum rate of 2x FMAC is possible in single thread.
