Samsung cannot meet what nvidia need for supply, so how are they going to manage with amd as well
What makes you think that? Nvidia not being able to meet demand does not mean Samsung are at max capacity for the node. Large ICs like GPUs have lead times extending into several months, and then you have to factor PCB manufacturing, assembly and transport on top of that.Quote:

LETS NOT FORGET AMD has GlobalFoudries who can use TSMC licence (speculation), maybe its GF who want to use 8nm Samsung licence- they did that with 14nmLPP.
I presume they're talking about 5nm, since that's what apple etc. are on.
Winner takes all, I am guessing Nvidia will have the buying potential to short out AMD for a while. Good on AMD for trying.Quote:

AMD's woes mostly come from limited TSMC 7nm production, but they are also having some issues with GDDR6 memory being supply limited.
GloFlo are not progressing to EUV so therefore they're bust for next generation lithographies.Quote:

EUV becomes PUV. And it's going to be awesome.
Actually.... I wonder what happens if I take a potato and expose it to lots of UV....
First, we had Bananaman, now meet, Potatoman!Quote:

That's assuming 8nm, but as kalniel says it could be more a case of planning for future products, particularly as the source mentions pushing against Apple for capacity (which could imply 5nm). And this wouldn't be an overnight switch anyway, even a backport of 7nm to 8nm for a complex product like CPU/GPU would take many months, by which time we might be seeing early ramp of 5nm anyway.Quote:

I remember CD from Semi-Accurate many years ago wrote an article about AMD Jaguar,and how AMD had designed it to be more easily ported to different fabs and process nodes. I suspect it might have been one reason why the console APUs used AMD Jaguar(and also its smaller size in MM2 compared to the bigger cores).
Yeah the Jaguar core was used across GloFo and TSMC. I think even some of their PC processors based on Jaguar were made across foundries depending on which SKUs you bought.
I forgot to add to my previous post. Regarding GloFo being a licensee or adding capacity for AMD; I don't think it's the most likely scenario. Part of the reason they abandoned their own 7nm was ostensibly down to floor space - they were already close to utilising what they had available and a shift to 7nm would have meant more new build (so more capital and waiting years) or converting existing floor space, reducing existing capacity in the interim and losing money.
Amusing to read this after those rumours that Ampere launching on Samsung's 8nm was only a stopgap and the plan was to move to TSMC in 2021.
Which could of course be part of the reason there's pressure on the AMD share.Quote:
