IC: Speaking to that process node, TSMC’s 7nm as you said: we’ve specifically been told that it is this sort of minor process update that was used for Ryzen 3000XT. Are there any additional benefits that Ryzen 5000 is getting through the manufacturing process that perhaps we are not aware of?
MP: It is in fact the core is in the same 7nm node, meaning that the process design kit [the PDK] is the same. So if you look at the transistors, they have the same design guidelines from the fab. What happens of course in any semiconductor fabrication node is that they are able to make adjustments in the manufacturing process so that of course is what they’ve done, for yield improvements and such. For every quarter, the process variation is reduced over time. When you hear ‘minor variations’ of 7nm, that is what is being referred to.
