Your point doesn't make much sense since foundries determine what is and isn't viable for mass production ... And it's NOT too early to move to 7nm since console APUs will be the size of a smartphone SoCs at that point so cost concerns are mitigated with smaller dies. You also misunderstood the article too, it only argued that you should transition to FD SOI from FinFET to reap more benefits. All home console manufacturers still saw reasons to use 14/16nm even though it's permanently more expensive per gate either way ... Sony still has to redesign the APU to use 7nm cell libraries ... (you can't reuse the physical design from older process applied to a new process since they don't have the same design constraints) |
1. Nope, it's not the foundries, but their clients who decide if it's viable or not for mass-producing their chips.
2. Yes, it is too early. Or why do you think AMD, Intel, NVidia and IBM (I singled out those because they are the only ones who produce chips with more than 100W TDP, which a 4K console APU will consume for sure) still don't have any 7nm chips out, announcing them for 2019-2020? Simply because the 7nm processes are not ready yet for mass production - especially not any 7nm HPP (High Power Plus, which is a general term used for the production quality of the chips for Computer and Server CPUs)
3. FD-SOI is a better bulk process. High performance chips wouldn't make the change to FD-SOI anyway because they couldn't reach the same performance as they do with more performant processes, which need FinFETs. The article says otherwise but that's not how it went in real life. It also hinted at IoT, or Internet of Things, as it's main use. Those only need a couple of Milliwatt in power consumption and are about as powerful as your cellphone 12 years ago, no comparision with a console APU. For those chips, FinFETs would be a huge waste, so there FD-SOI would make much sense.
4.Learn how chip manufacturing works before you see a price on 14/16nm over 20/22nm and 28/32nm and think it's more expensive to produce chips in that size. Because it isn't.
5. Again, it's not Sony who designs any of these things, they just state what the chips must perform. It's completely up to the manufacturer as on how to get there.
