Well we know now how they will bridge the long wait to Zen4 on AM5 Q4 2022.
Production start for V-cache is end this year so too early for Zen4 so this is certainly coming to AM4.
+15% Lisa said is "like an entire architectural generation"

Okay, at least we know there won't be a latency hit. That's a good sign. More benches please? Is there some embargo on Milan-X benchmarks?

Milan-X is selling retail now (okay technically its still in pre-order retail), why isn't anyone benchmarking it to completion?

No, the CnC team just got access to it last night, and were extremely excited to put out some initial data on it. More to come in the future.

ST is underwhelming due to low clock, but I don't know how low it clocked, Benchleaks said 3.1-3.2Ghz but it was showed 2.1Ghz in the GB page

probably wasn't heavy enough for the SMU to even bother ramping up the cores( i have this problem with GB on both of my Zen2 and Zen3 laptops) . that's the problem with GB , its really light and really fast.

I get it now. I was totally not factoring in the TSMC aspect. AMD's hands are tied coz they can't force TSMC to do whatever they need. They can't be TSMC's boss. They have to be nice and professional with them and can only just coax them to do their best. Intel has the upper hand here since they have direct control over their foundries and can dedicate the required resources to whatever the CEO/CTO dictate.

Hopefully, the server business boom will allow AMD to buy their own fab, hopefully dedicated for gamers :D

I think it is a little different. For SoIC stacking AMD is TSMC's partner, to get the technology to mass market. Just like Apple was the partner for N5.

So, it is not about AMD bossing anyone, it is their joint project and both sides will share the fruits of it being successful.

With node shrinks slowing down, advance packaging and stacking in particular is going to be another way for TSMC to manufacture increasingly capable products to customers.

It is interesting they show N3 as being available for top die in 2023 which is the first year it will really be available in quantity anyway. Nothing listed for bottom die, does that mean you'd have to use N5 for that?

The timing of the N3 stacking seems quite optimistic to be available on the same year it enters mass production.

AMD (and Microsoft) asked people who have account on Azure Milan-X to not publish any benchmarks.
