Nope, all Zen chips are same across the range pretty much(within each family, e.g. Zen, Zen+), just varying numbers of them (Threadripper/Epyc) or various cuts made to them (2x4 core CCX with a defective memory controller for Ryzen 1700-1800, 2x3 core CCX for 1600, 1x 4 core CCX for 1500 or whatever it is. There was a B2 Stepping for Epyc from memory though, with memory controller improvements, remember Epyc uses all functions on the die so is the 'top bin' as such in terms of defects at least. So Epyc got the newer dies in some cases with tweaks as it's their high value product, so can pay off quickest for this change.So yes, this is why Intel is getting hammered. They have to make a series of larger monolithic multi core dies to go over 8 cores. They have to make multiple dies for their product line. AMD only makes one really (assuming B2 stepping becomes the updated mainstream part also), so they can use 98% of their sillicon.. Intel has a high defect rate with e.g. Xeon 8180.They also have a lot of heat and growing efficiency issues as they are pushing clocks to stay relevant with AMD in multicore applications, let alone narrowly edge AMD on average in single core.
