So, our friends from Semaccurate wanted to get back into the spotlight. And are using unsupported claims they were the first to leak XOne and Switch specs.

The PS5 might exists and might be launch this Hollyday season. However, there is zero chance of it´s supporting a Navi GPU and may be close to zero to use Zen CPU cores.
First, there has never been a console with a Radeon GPU architecture that was the top tear of the year. And we even have to suppose those Navi cards are coming this year.
Second, there is no new mass market node production below 14nm that PS4-Pro and XoX use. The Scorpio chip is the biggest one could get at a $500 machine. And Zen cores are far bigger than Jaguar, supposing Navi CU are also bigger than Polaris and we simply don´t have enough "size budget" to create the SoC.
Third, even if the PS5 GPU is bigger, how the hell will it leverage bandwidth speed? GDDR5X? That would be a minuscule increase for an extra price. And the PS5 will need to have at least 12GB to reach full 4K most of the time. That is more $$$ over more $$$.
Conclusion.
There is no reason Sony would bet on new architecture at this point of the generation. If they feel the need to leapfrog the XoX, Sony can easily do that with more polished and overclocked Polaris+Jaguar pairs and 12GB of GDDR5. And may be they could get it at no more than $450.
Thoughts?

Semiaccurate has never said how fast things will be (afaik), thats always others that are speculating.
Semiaccurate basically said something like 8 custum Zen cores + Navi GPU architecture where confirmed by them.
"There is no reason Sony would bet on new architecture at this point of the generation."
I dont know what to say..... why wouldnt you make use of better technology?
If AMD keeps makeing new CPU & GPUs, and they get better (stronger & more effecient), why would you not want to use that?
Also I doubt even with 8 Zen cores + Navi GPU that it ll be more than 450$.
"Third, even if the PS5 GPU is bigger, how the hell will it leverage bandwidth speed? GDDR5X? That would be a minuscule increase for an extra price"
You know that GDDR5X allow potentially double the data moved at same time, as GDDR5 right?
Right now they dont run at same clock speeds, but this allows them to overall still be much faster.
Nvidia 1080's use this and have Memory Bandwidth of 480+ GB/s.
GDDR5X or GDDR6 should be more than plenty for a home console.
