News AMD Financial Analyst Day 2020: A Lot of Details to Digest

[Gideon]

I would say Zen 3 launches in July

I hope you're right, but based on AMDs statements I'm nott sure. Either way, if this is the case we should be getting leaks sooner rather than later.

If this ends up being true, I don't think AMD has to worry about getting bested in the mobile space:

Ryzen 4000 mobile laptops could hit “18 hours” of battery life, AMD says

Calling AMD’s upcoming 7nm Ryzen 4000 laptop CPUs a “watershed” moment for AMD, the company hinted that at least one model could hit “18 hours” of runtime.

[EDIT] Whoops misunderstood something. I don't think that is true. My understanding is that AMD has made big leaps with idle draw in Renoir but the way they do power gating is still a lot more crude than Intel and will not be fixed for some time.

Or rather, if it were true, it would also be true for Ice Lake and then some.

I feel the need to point this out: Genoa is a server chip, not the code name for the Zen 4 architecture. We will see desktop chips before the server chips drop. As to launch timing? Nobody except AMD knows, of course. If I had to speculate, I would say Zen 3 launches in July and Zen 4 will launch later rather than sooner. However, I expect Vermeer to launch in 2021 along with some variants of Genoa. The cheaper chips for both Vermeer and Genoa won’t land until 2022.

Vermeer is Zen 3 desktop, I think. I’m not sure if it will launch in July, but it should launch in Q3.

Source? I haven't seen any kind of technical deep dive yet on how Renoir handles p-states. We still don't have any official review numbers but the early leaks have been impressive:

AMD Ryzen 7 4800U-powered laptops may potentially offer stellar battery life compared to similar Intel offerings

A PCMark 10 battery life test result of an AMD Ryzen 7 4800U-powered laptop has leaked online. Although specific details about the laptop itself are not available, the test seems to indicate a runtime of 13 hours 52 minutes on a 70 Wh battery. This is a very good runtime and probably higher than...

Yeah, seems like Vermeer in the DT part, and likely Cezanne is Renoir's APU successor - as to what GPU generation makes it into Cezanne, RDNA at least though I would hope for RDNA2.

It will be RDNA2.

Renoir => Zen2+GCN // Small APU // 17h 60h-6Fh
Van Gogh => Zen2+RDNA2 // Big APU // 17h 90h-9Fh
Cezanne => Zen3+RDNA2 // Small APU // 19h 50h-5Fh
Rembrandt => Zen4+RDNA3 // "Big APU" // ¯\_(ツ)_/¯

Good: Zen 4 is officially 5nm. Not sure this was confirmed before; I think there was an outside chance it was would be 6nm.

I still wonder though whether they meant standard N5, or N5P instead - with Zen4 almost certainly late Q4 2021 to early Q1 2022 there should be more than enough time for N5P to ramp and increase yields.

With Zen3 merely built on an optimised N7 process (rather than EUV N7+), the move to N5P should be as beneficial as the move from GF 14/12nm to TSMC N7.

I also hope that the Zen3 X670 chipset will have a lower TDP, I skipped X570 because of the small (and therefore annoying) fan on most of those motherboards.

We can dream! But as a betting man my money is on N5. N5P will probably have a price premium, and N5 is likely to be expensive as-is. I'm guessing N5P exists for a very special pomaceous company's H2 2021 flagship device and, maybe, successors to that company's notebooks in 2022.

Has it been confirmed that Zen3 will not be N7P or N7+? While they removed the plus, they left ambiguity. Seems silly to not take the efficiency/performance advantages of at least N7P which will use same tooling, even if it's not a direct ancestor of N5 -- unless N7P yields are crummy, in which case all bets are off.

No.

No.

Intentional obfuscation. Basically not releasing publicly any information that might let us know the kind of IPC or efficiency gains they are actually likely to get.

Indeed. AMD never used TSMC's node names to begin with. Zen 2 turned out to use mobile oriented N7 with design optimized by AMD to still reach high frequencies, instead what some people expected to be a precursor to TSMC's N7P. I guess too many people were directly linking AMD's mention of 7nm+ to TSMC's N7+ so AMD severed that link. Now the question is why AMD even bothers with obfuscating such details, they have been and will be only guesstimates at best anyway.

Interesting long read by The Next Platform, a mix of AMD FAD coverage, looking back at the history since 2011 and discussion about AMD's strategy and plans. Some of the stuff we already discussed in this thread and elsewhere on here put in some new context.
