4/8 Skylake SP CPU with 1MB L2 and 1.375 L3 per core = 9.5MBThe L2+L3 configuration is unlike anything that Zen has.
I sure hope it's not hyperthreating. If I were interested in a cloud gaming box I'd feel much safer with SMT.
Fwiw, I don't think this Stadia is a good idea. But google will probably come with some interesting add ons that are big improvements over their androde VR/3d tech.
I doubt they have the latency to cancel in 6 months.Knowing Google, it'll be cancelled in 6 months.
Reading between the lines, it looks to me like a Vega 56 with 8 GB of HBM2 + a Skylake-X derivative with 8 GB of DDR4.
Lisa’s Twitter specifically says “GPU partner”
So does their Investor Relation post

No mention of AMD supplying the CPU...
Seems plausible. I wonder if we'll get to know exactly what it is by going into the game's settings menu and running a benchmark, like the way it was discovered that GeForce Now uses Tesla GPUs.4/8 Skylake SP CPU with 1MB L2 and 1.375 L3 per core = 9.5MB
They specifically said Custom X86 so ARM is 0 chance, and this is definitely not Rome. It’s either Naples or Skylake SP and my bets are on SkylakeMaybe that's because they aren't ready to release specifications on the Rome architecture. The EPYC architecture and EPYC platform is a no brainer, it makes no sense to adopt an inferior platform from intel. The only other option than EPYC IMO is in house ARM design.

Stadia clearly looks to be a custom single die AMD GPU with the x86 CPU on chip to run the games autonomously on the GPU.
STADIA: ONE SINGLE DIE
GPU: 56 out of 64 CU used.
CPU: 7(?) out of 8 cores used.
MEM: 16GB of HBM2 (two stacks) at 484 GB/s

If it's monolithic then it's a very good guess.
I think it's a little more likely to be MCM because the 64CU (minus 8CU )GPU is so massive and on 12nm would be almost 400mm2. So they use 7nm GPU chiplet which is not custom (used in other product lines) to lower otherwise very high development cost.
I agree with folks it could either be intel CPU solution or maybe just Pinnacle-L, a one CCX version of Pinnacles, with half a MB of L3 or L2 unused maybe for use as a buffer that both GPU and CPU can quickly share data with.
How would an Intel CPU use the HBM2 memory attached to the GPU as the main memory?
~600 mm2 on 14nm would not be to big (although an MCM is not necessary impossible)
The CPU clock frequency of 2.7 GHz and the smaller L3 cache (6MB?) point to an integrated CPU (Zen1)
