I see what's going on here, Zen 4 will be launched at Computex with availability in July.
Zen 4 will be DDR5 only but to give people a DDR4 option Zen 3 will get a 6nm refresh, probably sooner than July tho.

Do you have any source about the ZEN 3 refresh? That would be intriguing...

Milan-X is already on 6nm.
Some mad man overclocked a pair of them (128 cores) to 4.8Ghz

Those "B2 stepping" Zen 3's that AMD said "are no different to B0" well they are 6nm too, someone got a B2 5900X to 5.15Ghz at 1.4v, 4.7Ghz is what i can get with my 5800X at 1.4v and its a golden sample, read in to that what you will.
Also ignore CPU-Z its reading 7nm is not accurate, its not reading that from anywhere its hard coded.

RX 6#50XT refreshes....

I doubt they are.... nothing to go on with that, i think AMD are shifting everything to 6nm and 5nm this year. Just an opinion.
Hope you're right Humbug, as a RX 590 owner (and just made my wife happy with a RX6600 from OCUK) an affordable RX 6000 series refresh would be perfect for my next PC...

Same, i'm also looking for a new GPU this year.

Product mixing nodes is something i think AMD would do, its what Lisa Sue calls "cleaning the pipes" its to bed the node in and fine tune it before transitioning over fully.

No they aren't.

Everyone who has tested B2 Stepping agrees they are better in every way than B0.
Do you think that's architectural design changes this late in to Zen 3's life cycle? 6nm was designed to be compatible with existing 7nm designs, the node transfer is easy and TSMC have said they want everyone off 7nm and on 6nm.
Its easier to move 7nm products to 6nm that it is to make architectural changes.
A decent upgrade? Hopefully otherwise some Intel Iris part will be the iGPU champ (ignoring Apple).
However, the 6500 XT at 100W is only about RX590 so I cannot see an APU getting to that. RX560 to RX590 is around 200-300% depending on the benchmark, and I cannot see an APU reaching any time soon.

They are better, but they aren't 6nm.
Yeah, no way they can move to 6nm and keep IPC the same. It must be an incremental improvement on 7nm.
(There could be performance improvement between steppings of same model, but those would come from better perf/watt allowing for better boost)

That not how it works, need to physically alter the design to change the ipc, node shrink brings power savings, can either bank the power savings or up the performance keeping the old power limits, stepping changes usually arise to increase yields
AMD 5nm Zen 4 based Ryzen 7000 might launch in April alongside or soon after the release of the 5800X3D.

Leaker getwinder claims:
The instructions per cycle (IPC) on Zen 4 is 18% higher than a previous architecture (neowin aren't sure if it's Zen 3 or Zen3D).
The peak frequency or the maximum boost on a single core is 7% higher.
The all-core boost is raised by 8.7%.
AMD has already showed a 5GHz all-core Zen 4 demo running Halo Infinite back at CES 2022 and if the 18% IPC is correct, it seems AMD will be at the top again.

Im pretty sure it won't release so early, and im sure IPC increase will be higher, AMD already showed they can increase 19% on the same node, so 25%+ IPC is realistic, but we will see in april, both of those rumors are either true or false.
