Question HBM Genoa

Charlie is just rambling about MI300A mostly:

AMD outs Genoa HBM… Sort of… as a GPU

At AMD’s Datacenter and AI day a few weeks ago, the company stealth announced an HBM Genoa CPU, sort of.

The CPU only MI300C doesn't feature at all so Charlie probably missed it.

The Mi300c was not featured in the presentation, but it does not mean it is not coming out at some point.

Probably left out just so that it didn't steal the spotlight from Bergamo and Genoa-X, which are shipping now.

Too boutique to be an actual product.
MI400 gen maybe, Zen5 is a lot better for silly FMA crunch.

BTW, in the locked thread, you mentioned ~2,400 mm2 ballpark of silicon on the Mi300a, which is what I have been calculating as well.

Which is probably a little more N5 die area than H100 (1000 mm2 vs 800 mm2?) + 1400mm2 of N6. Maybe 200 mm2 for CCDs and 800 mm2 for GCDs.

In theory, if the N6 was mostly SRAM, it could be 1 GB to 2 GB of SRAM.

I wonder if AMD is getting the sufficient bang for the buck on all this silicon...

That was for X but A is somewhere in the ballpark too.

Dylan has accurate die sizes listed in his article.

Well I mean it's an extremely high-margin segment and the solution seems very-very competitive so they're totes okay with piling up on costs.
 
Azure seems to remain AMD's best and most reliable business partner among all of Microsoft's business units.

This is getting OT, but there were rumours like the next Xbox being ARM based, Intel wanting to do the chip at its IFS etc. pp. and all those detours leading to Microsoft lagging behind Sony at actually designing the next console gen. Not that I really care either way. 🤷‍♂️

Yea they are, have worked with ATi since 2005.

Spencer is bad at management.

He pitches a good acquistion but Xbox as studio management just doesn't manage their properties at all.
It takes real skill to buy Zenimax and then have 0 Fallout games in production until ~2030 or so.

They aren't good either, but at least they manage their IPs.

You mean nearly literally go scorched Earth to litigate all of their game IPs from even a hint of third party usage. They are nibbling away at their own corporate goodwill each day...
