HardOCP's Tyler is backing the leak as reality. 16c/32t on AM4 at 5.1GHz, plus the full 256-bit AVX2 pipeline and other IPC improvements, for under $500 (albeit, will need a new motherboard due to out of spec power requirements). Threadripper starting at 24/48t all the way up to 64c/128t @ ~5GHz. Not covered in the leak is this bit of information I know leave you with for the Zen2+ refresh in late 2019/early 2020. Back in 2012, when they began to ramp up production for PS4 and Xbox One silicon, they realized they had a problem on their hand. Like any semi company, they had all of these different products using different monolithic designs and so defects past a certain threshold in the silicon went to the scrap heap. Worse, large scale production of one particular CPU had no leveraging effect on yields for other different CPUs, each different CPU got binned separately. No surprise there. The obvious solution to this problem would be to use the exact same chip for all product SKUs, utilizing an upfront more expensive 2.5d IC/SiP design, so that they could bundle up more than one chip on the same package to scale to all of their different product requirements. Makes sense. Everyone knows this story.
But here's the genius part. They knew one day, new game consoles would be launched and that they could do it at near cost as before for each console manufacturer. But this time, they were going to leverage the economies of scale of the console market for all of their other products. The PS "Five Guys" and Xbox "Zero Ultra" are both speced out as 8c/16t CPUs + 12CU Navi on the same SiP. But they're actually using two 8c Zen 2+ chiplets, with as many as 4 defective cores each. The interposer is the same one used for Epyc/Threadripper, which has redundant memory controllers for HBM2/GDDR6/DDR4. PS5 is using HBM2, next XBox is using GDDR6. The Navi chip is the same 20CU chiplet used for Zen 2/2+ APUs and discrete GPUs. All of their junk silicon is going into the consoles, and this is going to massively increase the amount of silicon for higher-tier bins. Zen 2+ will hit 5.6GHz or higher on the desktop (another 10%-15% clock improvement) plus some more IPC tweaks. Even thought Intel has had a much larger market share, and thus has traditionally been able to bin their CPUs higher, AMD is going to completely rape them when it comes to yields and binning.
This is why AMD is completely confident on TSMC's 7nm, while Intel is completely fucked. And the word on the street is that at the same time, the top four IHVs will be certifying Epyc for the datacenter.
