WTF? A 325mm2 chip is a 325mm^2 chip. No matter what. Roughly same number of chips/waver than a 350mm^2 chip. The 7nm node currently is considerably more expensive than the 28nm node, hence a 325mm^2 7nm PS5 SoC is considerably more expensive than a 350mm^2 28nm PS4 SoC. |
I don't see what the issue is.
On 28nm, sony made a 350mm2 APU that ost them around $100. With the PS4pro, they made a 325mm2 APU on a 16nm process. Smaller chip,bt way more powerful.Sae with the PS5, I am expecting it to be another 30 - 325mm2 APU on the 7nm process. And yes, while 7nm fab is more expensive than 28nm, what makes it more expensive is the technology and not the wafer itself. Hence the "tech tax". But sony putting in orders for the PS5 APu (just as was the case with the PS4) isn' like most other companies. While the likes of AMD/ NVIDIA would putting orders for only like 4-10M chips on any give fab process per year, sony would be putting in an order of around 30-40M chips.
Trust me, that changes the cost conversation a great deal.
But what really feeds this estimate here is actually with me looking at the $499 Nvidia RTX3070. That's a 390mm2+ chip on a Samsung 8nm process, and its cooling system, board, RAM...etc and being priced at $499. And with things like GPUs, be rest assured that there is a very hefty mark up on that MSRP. Case in point, Nvidia is known to sell stuff for as much as 2-2.5x times more than what it actually cost them to make it.
