No it's the actual CDNA4.
Different stuff to support way different speeds and feeds.

That one moves the paradigm into a different direction.
Used to be called MI500.

Mi400 should coincide with HBM 4 in 2026.

Since HBM4 will be SoIC stack, I wonder if my prediction will turn true, and at that time, AMD will have HBM stacks on top of base AID dies...

Weird that no pricing info was released for Ryzen 9000 and no release date.

I think the pricing will be roughly the same as Zen 4, and given the IPC uplift is underwhelming, AMD will have to release V-Cache models ASAP, hopefully before Christmas, at the time of Arrow Lake launch.

There were some rumors that the next version (presumably CDNA4) would reshuffle the die sizes, moving to fewer and bigger dies.

If that's part of the plan, would that be part of the Mi350 (using the current naming) or one after that, Mi400?

Why ask someone just caught red handed lying to everyone for the last year?

So the sitrep is thus:
Granite Ridge: 20% IPC is the goal for a major tock, it failed. V-Cache will save the day in gaming so we are more or less status quo assuming LNC is a similar IPC bump with a small clock regression.
Turin: Still dominant, looks better than desktop does for sure.
Strix: Good, should be enough to justify the big jump in design wins, also looks a bit smaller than expected.
Z5 in general is the smallest bump since pre-Zen, but it does enough to retain its place in the market.

For the other stuff, Versal is great, MI roadmap is excellent and the overall ecosystem is looking very simple and workable now, which is great for everyone.
We will wait for all the final details and deep dives to get the full picture, overall it looks steady and solid, but unfortunately expectations were to kill the comp.
AMD themselves though never lied, this isn't an RDNA3 situation.
And to MLID, well you get to live another day, at least until LNC ends up being 15-20% IPC.

Yeah packaging yield is a concern so less dies balances the net yield. Wafers are plentiful relative to adv packaging.

This slide was spot on, seems Zen 6 with 10% IPC would be what I would bet on.
MLID the winning leaker.

AMD took almost two years for a paltry 16% while Apple and ARM iterating on almost yearly cadence.
Based on that trend, whatever comes after Zen 6 is gonna have like 5% IPC increase and then after that 0% IPC uplift.

And yet your proclaimed +32% has been proven to be wrong, and the MLID slide's "10-15%+" has been proven to be right.

What are you actually arguing here?
Not an MLID slide. I was the one that convinced Adored not to do a video on it, because the IPC number was lower than expected. My fault for accidentally giving MLID more credibility.
