AMD Zen 2 (Refresh) 3900XT/3800XT/3600XT

Im pretty sure the 3950X is 2x3800X chips.

Sorry, but an absolute NO.
Both cpu's have the same TDP, 105W. At the same time both cpu's have completely different clocks and boost clocks, the 3800x is 3.9Ghz all core and 4.5Ghz single core. The 3950x is 3.5Ghz all core and 4.7Ghz single core, like most mine actually all cores at 4.1Ghz and certainly gets to 4.7Ghz single core.
The 3950x is most certainly a binned part. Considering it only became available just before Christmas tells you all you need to know really, AMD were binning the parts long before the 3950x was actually released to retail.

Lol, heard that many a time and of course it's complete rubbish. Epyc only has to to meet voltage, TDP and clock speed set for it. No company running Epyc is going to enable PBO, XFR or overclock it, they will just run it at stock.
Everything "down" from Epyc is almost certainly binned, because it has to be that's the philosophy behind the idea of chiplets.

Low leakage usually IS better silicon though. The improvement in process/yields allows for clock bumps like this. AMD wouldn't launch a refresh unless they enough good die to trickle down

I don't disagree with that thought, but it's actually a lot different from "All the way from Threadripper down is "junk" silicont didn't make Epyc" :D
 
Are any zen 2 owners actually going to upgrade to these?

They look decent for a proper upgrade, but I cannot see the point in upgrading from the current CPU’s to these. Especially seeing as Zen 3 is coming soon(ish).
 
I am thinking about a 3600XT to replace my 1700, should be a nice improvement, just waiting on prices and release date, also hoping it will work in the CH6 as wont be swapping the board out.

Thinking about it depending on performance boost over my current cpu. Zen 3 seems to be more next year with amd starting the launch with epyc near the end of this year.

Exactly what I came in here to post. From what I've read around a few places, it seems that we can expect it within the next 6 months, however I'm not overly confident on whether these leaks/rumours are good enough to make it obvious it means an actual consumer chip release.

Probably make sense for owners of 1xxx and 2xxx CPUs depending on BIOS support. They should just drop into 3 and 4 series motherboards with minimal/no BIOS update, as they are just clock tweaked parts. Not swapping out my 3700X until DDR5 I think. If a 3950x comes my way 2nd hand though...

I recon epyc is the top bin from playing with the chips I have vs my threadripper small sample size though to be fair. I think their is a lot of truth in it but of course it's not all true as the 3950x exists!
 
Isn't pretty much every cpu and gpu a core that didn't make the grade at higher level to some extent (due to voltage, requirements, clock speed etc)? It's not like they make a cpu and know exactly what speed it will do, there's probably a frequency range and some are suited to higher speeds than others.
 
I really can't understand why anyone in their right mind would upgrade to one of these CPU's, the performance difference is largely insignificant. It is clearly a stop-gap solution aimed at retaining the performance lead and will be eclipsed by Zen3 in a very short amount of time. Anyone with any sense, if they must upgrade before Zen3 hits, wil be waiting for the XT CPU's to come to market and then buying a regular 3600x/3800x/3900x for a reduced price.

When are they due to arrive?
