So he thinks there will be 3640 Navi cores... Meaning 1539mhz core clock to achieve the FP numbers.
Being Navi based would suck though.
In short... Expect around Vega 56/Vega 64/Geforce 1070 Ti/Geforce 1080/Geforce 2070 levels of performance... Which should be mid-range levels of performance by the time 2019 rolls around.

16GB of GDDR6 memory... With 14GB available to developers. - Either Sony has managed to significantly optimize their software stack, making it less memory intensive than the Playstation 4... Or. They are including a secondary large pool of DRAM for OS/Background tasks just like the Playstation 4.

As for the specs, with a late 2019 25th anniversary launch, I'd say they probably wouldn't be all that far off at 6 Ryzen cores and Navi around 10TF, on 10nm-7nm, but I have a hard time believing it's Zen 2.  Ryzen, or maybe Ryzen+, but not Ryzen 2. That line of CPU's won't launch until early to mid 2019, so that would be way to new to go into a PS5 6 months or a year later. Also too many ports. Maybe for dev kits, but not for retail. 2TB should be the absolute min for the base console since Pro is already getting 2TB models. I'd also assume a $499 price unless PS eats $100 per unit.

AMD has confirmed that the Zen 2 design is completed. - There will be some sampling of chips in 2018 with a full launch in 2019.
Remember... CPU designs take years, many years. - Sony and Microsoft can leverage that.

If there isn't Zen 2 in next gen... I honestly would be surprised.

1550MHz seems too high, unless Navi has some voodoo magic or the PS5 is an XB1 at launch. XB1X is only 1175MHz, and that's with a vapor chamber heatsink.

The memory does seem off. Either a 20GB pool, or 16GB with separate OS RAM like you said.

I'm not worried about Zen 2 in terms of design or being ready, I'm worried about price. How much is a 6 core Ryzen 2 going to cost on 10nm or 7nm by late 2019, and hot much cheaper will PS get it for? While it should be semi custom and not a full blown Ryzen 2, I see the price potentially being an issue, unless they scale back elsewhere, up the launch price, or eat some more cost. If they had a long enough lead over Scarlet, they could just go with $499 for the first 6 months to a year, especially with the 25th anni hype.
