They already said they'll split the compute gpu and gaming gpu lines. Next gen MI 100 instinct cards are GCN with 8096 compute units. Can't find the link with all the specs, it's on reddit.
This!3) I'd like to see some basic GPU integrated in IO chip. Something like AMD Phenom northbridge 780G was. For the 2D desktop and office work would be OK and it would have few transistors on 12nm.
Who cares about iGPU.
1) AMD is developing APUs for Sony and MS consoles based on Zen2 + custom RDNA 2nd gen. And all these to be launched next year. Why would AMD waste workforce to develop something very different?
OEMs don't, besides Apple, so whatever.Budget builders, OEMs. Those sorts of people.
Both console SoCs are single-die solutions.If, in fact, that's how they're going to do it.

No idea.Is that to reduce IF power usage?
Yes. IF communication consumes much more power than inter-die comm.Is that to reduce IF power usage?
It's another big update, expect >15% IPC gains.Guys, what about Zen3 aka Ryzen 4000?
They will use Renoir as base for console chips IMHO.
No, console SoCs have absolutely nothing to do with Renoir (or any other AMD product).An interesting prospect, given that most of the leaks point to PS5/Xbox2 using 8c chips.

They will use two blocks of CCX, each CCX has 4c, so 8c total. CPU cores are the easier part of APU. They can add as many CCX as they need.An interesting prospect, given that most of the leaks point to PS5/Xbox2 using 8c chips.
Absolutely nothing... such a strong words. We know they will use Zen2 or Zen3 CPU core and custom RDNA GPU. IMHO This looks like it has a lot to do with other AMD products.No, console SoCs have absolutely nothing to do with Renoir (or any other AMD product).
R&D in semi custom business usually feeds back to AMD consumer products, but not the other way (e.g. the 2x 4 cores topology so prominent in Zen originates from the consoles). The consumer APUs so far are low budget cut down designs of existing silicon that use parts of next gen microcode as the most exciting novelty.Absolutely nothing... such a strong words.

Wasn't the first AMD 2x4c design CPU called Interlagos (server 16c Bulldozer CPU) introduced in 2011? PS4 console is 2013 product (and PS4 CPU core Bobcat is derived from Bulldozer). It just looks to me that consoles and custom business is based on other AMD products not the other way IMHO. And it makes sence that custom department is using already developed products of CPU and GPU departments and combines them together into custom chip.R&D in semi custom business usually feeds back to AMD consumer products, but not the other way (e.g. the 2x 4 cores topology so prominent in Zen originates from the consoles).

I remember that in the Anandtech interview , where AMD's commented on the GloFo 7nm cancellation, they explicitly said they only had one product there, that was supposed to be released in the end of this year.
Considering that Rome and Matisse use the exact same chiplets, it would sees really odd to abandon all the possible savings by fabbing them in multiple places. Let's also not forget that Matisse wasn't supposed to come out at the year end.
My bet is, that the planned product on GloFo was the 7nm APU
Good news for Radeon VII owners (sort of) wrt longevity of the platform's driver support. Bad news for actual Renoir buyers.
In a bandwidth limited scenario and power limited scenario navi is extremely more efficient than vega.
Due to the wsa amd needs to continue selling 12nm apu so what they need is something to complement it on the mid and high end. Something that can maintain their lead on gpu perf. Navi can do that. Vega wont. Zen plus api is fine as is and good at offloading 12nm capacity and fulfill the wsa.
From a brand and broad portfolio perspective zen2vega apu is just bad and another defensive old style amd thinking decision. I hope they waited the few extra months to get it right first time.

2) They could do small trims to console chip: to use DDR4 mem ctrl instead GDDR6, cut off half of L3 cache, make proportional vanilla 2ndRDNA to mem bandwidth... and voilá Renoir.

Unless those customers want Vega's compute capability. I seem to recall one of AMD's APUs being popular because it had their highest double precision performance outside of their professional GPU (since they locked that down on their lower GPUs).
Navi is better in real flops@mm^2@watt anyway.Unless those customers want Vega's compute capability
Because they might legally not be able to use those APUs elsewhere. Also different markets have different needs.
Carrizo. It somehow got 1/2 FP64.
Wasn't there a plan, or even an implementation, of Carrizo in some custom system that specifically had a use for that FP64 capability? I think I remember reading that some place.
