What makes you think ... 56C/112T Sapphire Rapids ... will be competitive with a Zen 3 64C/128T ThreadRipper Pro?
One makes assumptions. I note that the TR Pro doesn't just have a 64 core sku. I'd also note that I'm not likely interested in the high-end, and the 24 core got resurrected, so I'm not alone.... Also, we have no idea about pricing. I would hope HEDT $ < Workstation $, but this is also AMD $ vs Intel $, so....
The Thinkstation P620 isn't cheap if you price out something for 32 cores. Leastwise not in my book, ymmv.
...cooled and kept under TDP.
Yeah, I think I might have mentioned that one. But I think the whole AMD vs Intel thing is boring. I think HEDT is AMD's to lose, and AMD appears to be busy making the moves to ensure that outcome. At least that's the way I see it being sold in the press (TR is dead, long live TR Pro). I'm unconvinced.
In my head, AMD decided to direct a ton of production towards Milan, TR kept getting deferred (I've got a bone to pick about doing that while we were all at home working, but nm for now (*)), and now they're coming up against the Zen4 launch. Zen4 isn't just a core upgrade, it's a whole bunch of connectivity upgrades (memory/pcie), and their competition beat them to it (oops). They have these b-to-b agreements regarding TRPro that they have to live up to, so fine, they're doing that, but otherwise.... Drop the TR-Zen3, there's no point in launching it after TRPro-Zen3, and there's no way their partners are going to wait for a whole TR launch cycle to get to TRPro. Aside from which, AlderLake forced them to ship Zen3-X, which just makes for too many moving pieces. Optimistically, TR could launch 5 months after Zen4 desktop (that's what happened in 2017 iirc), which would bring it in quite close to the SR-AP launch. Pessimistically, Microsoft has bought every platter TSMC can manufacture and no one is seeing anything for awhile. I'm also interested in when 3000Embedded is going to rev (if ever), and when V3000 is going to appear, which has no place in a TRPro thread, except that I think all of the coordination of these launches are intertwined with the decisions on which things are going out when.
Edit (*) okay, I can't help myself. I thought it would be smarter to launch TR before AM5 due to DDR5 and pcie5 premiums. Why not add that premium to the platform with higher margins and defer creating the AM5 IO die (leveraging the work you're already doing for Genoa). And then I saw the Genoa package :]
