PS5 GDC Reveal and PS5 specs/performance Digital Foundry Video analysis : 3.5 Ghz 8 core Zen 2 CPU along with 10.3 TF RDNA 2 RT capable and 16GB GDDR6 RAM and also super crazy fast 5.5 GB/Second S

Sure. Keep in mind that the 2060 Super can match the RTX 2070 though and in some cases even beat it by a tiny margin.

And Sony has provided a "best case scenario" with it's clocks, there is the potential that a developer will prioritize CPU tasks at the expense of the GPU, you can't peg both chunks of the silicon and maintain the full 3.5Ghz+2.23Ghz.

There is the potential we could see the GPU limited to something like 2ghz or about 9.2 Teraflops for what it's worth.

It actually sounds more complicated than that. 

1.) GPU and CPU both had to be capped because they would otherwise run faster.  

2.) Cerny said that both would usually run at the max speeds.  

It was mentioned later that they tested higher speeds but to ensure optimal  stability so the PS5 could run at those speeds long term they pegged it at those speeds that's why they said it was the maximum and also the base who knows those pegged speeds might even be under the optimal to give some head room. Cerny also mentioned throttling if it occured would be minor with a 10% power decrease only need a  ~ 2 % frequency adjustment.
