Will there be a TURIN with V-cache?
Do you prioritize manufacturing resources on the packaging of cDNA GPUs?

I wonder how much of this is due to real silicon differences and how much due to BIOS, I think when he tested HX370 he had a lot of issues keeping the Asus he had from throttling, he eventually succeeded but I don't remember if that was thanks to replacing the machine with other Asus model. Anyway what I wonder about is did he had a chance to test other laptop SKUs with HX370, or does he base his investigation on the early samples he had access to.

I asked him about it:

He had two samples, his STX v/f curve is based on the retail ZenBook S16.

I suspect that there was some tailoring of the lithography process between STX and KRK. As has been said multiple times before, both AMD and TSMC have other customizations that can be implemented in a given chip within a lithography node. While both of them may be manufactured on N4P, KRK is very likely going to be optimized for use in laptops that have less cooling and lower power limits as compared to STX. It will be interesting to see if the STX refresh will have any further process optimizations using lessons learned from KRK.

It's sad Well, it can't be helped because the packaging is given priority to cDNA GPUs...

AMD needs to wider. Intel and Apple are already 6 and 8 wide respectively.
