I don't think that AMD is looking for high overclocks with this chip. They are using high density libraries for this chip.
Their primary target is the Broadwell-D and that if you look, clocks and memory configuration will be similar. There is another thread which talks about power consumption at...
There are 3 variables going on here:
1) Ryzen has half the FMA mathematical operations compared to Intel.
2) Ryzen has 2 AGUs but Intel has 3 (it has an extra store port)
3) Ryzen cpus have dual channel memory and Intel has quad channel.
Your examples mostly point out to the last 2 points...
Many times the FLOP/cycle count of a particular chip gets overstated due to the presence of FMA. The real FLOP count if only using mul or add is half of that rate.
People need to realise that there are other operations too like division and square root and they run at half width (128-bit) on...
If people consider the financial side of things most of the money comes from selling servers.
So I think they are targeting Broadwell-D and hence they made their choices by comparing Broadwell class chips like 6900K.
There is also EX series and the Naples platform is probably designed to target...
