Cost: What do guys think HBM3 will cost? It will be new tech. New tech tends to be priced higher as OEM's look to recoup development fees before passing benefits to consumers. Traditionally, consoles have never gone with the best RAM setup available, nor targeted the highest speed chips. Costs matter. This is why I was of the opinion that even Microsoft will not go bat shit crazy ages ago........you want to build a mass market product at a cost that you can sell it at.
And with the volumes that Microsoft and Sony more so will be dealing with, those (costs) can ramp up pretty fast.
And yes, I know that the main reason you need SSD is for faster streaming. But the question still is, why would anyone need 20gb HBM3 at 700gb/s? A $1200 nvidia card has 11GB GDDR6 RAM at 616gb/s. I doubt that these consoles are competing with that card in terms of performance.
