Which I already pointed out in another comment. IIRC all 3 foundries AMD works with. Tsmc, gloflo, And Samsung developed “10nm” nodes. And had issues with them AMD opted to skip them and design around the 7nm process currently in the works. So those fabs are making “10nm” products they’re just not being used for standard processors and GPUs.
While Intel’s nodes tend to be closer to what they’re named for. They’ve basically redefined the metric so they can claim their numbers are “real”. So the whole thing gets pretty confused in comparing them both. Because you’ve got processes that are equivalent in size. But then you’ve got nodes that are equivalent in the order of stepping.
Intel’s 10nm is an intermediate node because it’s in between the industry standard 14mm and 7nm steps, whatever they call them and whatever the actual sizes are. All the other foundries effectively skipped that step (they’re using it but not as their main thing) . The tsmc/gloflo 7nm is smaller than 10nm but bigger than 7nm. And will be smaller than Intel’s 10nm. So it’s weird the 7nm we’re hearing about is closest in size to Intel’s 10. But it’s one step further in the order of operations.
The situation has lead me to believe there’s something off about that particular intermediate stepping. Regardless of relative size they aren’t the only ones to have issues with that step. Why goes a bit beyond my interest. Just been trying to get up on hardware again so I can rebuild my box next year.
