AMD's SMT implementation is likely very similar to Intel's. Given the degree of cross-licencing AMD and Intel have as well as AMD's past ties to IBM (who have been using SMT in their POWER processors for quite a long time), it would not have been difficult for AMD.

SMT has been a pretty big factor in performance for almost every part that possessed it.

In well threaded tasks, there is a 20-30% difference, on average, in favor of the part with HT, all other things being equal.

I dont think there is any public figure except we saw it can run a game for like a minute but may be with four titan x and not much cpu.

Frankly I could care less about how much power it consumes, If it gets Double the single threaded performance at the same clock speeds as my 8320 then I don't care if it has a TDP of 250w as long as it comes with a cooling solution that can handle the heat.

People really need to stop tying Zen's potential performance to anything prior from AMD in terms of hardware. The only commonality between Zen and AMD's past is Jim Keller himself being back.

Jim never designed a fast desktop cpu before.

I don't think you understand how small the changes in x86 designs really are over the years.
