So we are going from :
"9.2TF???Sony is skimping! This is unnacaptable"
...to
"2.0GHz?? Are they mad? 36CU Navi at that clock will burn your console, should have gone nice wide and slow"
1. There are rules to chip design. Navi CUs are much larger then GCN, therefore they are not straight comparison vs PS4Pro
2. 2.0GHZ Navi, that was product of many years of work and big budget, will almost certainly be better chip then first Navi's that AMD released 1.5yrs before this one is released
3. I assume console manufacturers will use N7P node, as this does not require chip redesign but will give them round about ~10% better TDP at same clocks
4. Wide and slow vs narrower and high clocks is not clear cut. Bigger die sizes are getting more and more expensive. Chips with high transistor counts cost much more then the ones back in 2004, there is a reason why Nvidia and AMD are pushing frequency. Its BETTER.
Really, up until 12TF mini PC premium SKU that MS shown, everyone would have LOVED ~13TF Vega with RT and VRS in next gen console so I don't really understand what is the fuss? Only way Sony will ever match MS is if they go with 2 SKU strat or say "Fuck lower end, Lockhart can eat bottom end, we will only release premium SKU" which, IMO, would be suicidal.
So yea, bottom line. 36CU at 2.0GHz is achievable in 2020, especially on N7P node. It will still result in very advanced console and 399$ is NOT guaranteed. Fact that they went narrow and fast does not mean going wide and slow, like 56CUs at 1500MHz would result in better performance. Only if wide and slow means, 56CUs at 1700Mhz+, which I imagine was never a plan for Sony as this is very much as premium as it gets (and, will have to be unorthodox large compared to every other console released ever).
