Is there a chance Badami/Trento is Zen 3-based EPYC with updated I/O (on SP5 with DDR5 and PCIe 5) to be launched in Summer 2021? In a Q4 2018 AMD roadmap such a product was listed (although under the name Genoa, which is now Zen 4 and expected in H1 2022). This would help against Sapphire...
That's what I expect AMD to launch beginning of next year as successor to Dali, although I'm not expecting more than 4 CUs. I don't know whether they will use it for low end Ryzen-branded laptop chips or only for Athlon and Ryzen Embedded. However, I'll be surprised if they won't launch a Zen...
Isn't that huge market mainly about business and other non-gaming desktops where Renoir is a great fit? For AIOs and Ultra SFF power efficiency is an important factor and hence a hypothetical Zen 2 backport to 12nm would be worse than Renoir.
OEMs could presumably also build AIOs with Renoir or...
The Pro 4350G is more efficient, which may be important for SFF builds. It also presumably supports ECC RAM, which is important at least for some servers. And a non-gamer might still benefit from having more GPU power than Intel UHD Graphics even if they don't care about Vega 6 vs. Vega 8.
They already have a DDR4 controller on 7nm for Renoir. PCIe is only 3.0 on Renoir but this might also be an artificial limitation. That said, I don't expect Milan to have a 7nm IO die.
3rd Gen Threadripper on TRX40 "only" has 72 PCIe 4.0 lanes available to devices, up to 56 from the CPU and up to 16 from the chipset. 88 is mentioned in some places but it's a misleading and useless number as it also counts the lanes used by the CPU-chipset link.
Additional PCIe switches on the...
With Zen 3 they could also sell a 10C SKU with two 5C CCDs. I don't know whether this would be worth it, however, they could sell it for a bit more and it would provide clearer separation from the 8C SKUs (where there will already be two variants in the 4000 series: Renoir and Vermeer).
That's just the 8-thread performance. UserBenchmark is hiding the 64-thread performance further down and, according to that, Renoir 4800U is 121% faster than Ice Lake 1065G7. The Ice Lake 64-thread score is oddly lower than with 8 threads, though, while I'd expect it to be about the same...
There was a 16C Castle Peak Threadripper on the September product master, though:
CPK DT Ryzen Threadripper 16C 280W SP3R3
This doesn't guarantee that they'll launch a 16C Threadripper but it's possible.
Is it possible that this rumor is only about APUs? APUs currently lag behind by a Zen generation (or at least half a year). AMD might want to change that. They could skip Zen 3 for APUs and directly move from 7nm Zen 2 (Renoir) in 2020 to 5nm Zen 4 (Rembrandt?) in 2021, thus skipping 7nm+ and...
