AMD "Vega" Die-shot Revealed

AMD released the die-shot of its "Vega 10" ASIC. The multi-chip module (MCM) of the GPU die and two HBM2 memory stacks, sitting on a silicon interposer, is slightly smaller than the "Fiji" ASIC, as it features just two memory stacks. AMD didn't label the components of the GPU die, but we can make out 8 shader engines, holding 8 GCN compute units (CUs), each. This is unlike "Fiji," where the GPU holds four engines with 16 CUs, each. This would mean that each group of 8 CUs has its own dedicated geometry processor and rasterizer.

Since each CU holds 64 FP32 stream processors, we arrive at the total stream processor count of 4,096. Unlike "Hawaii," these stream-processors are FP16-capable, so simple compute tasks are handled at double the throughput. We also make out 32 render back-ends, double that of "Fiji" and "Hawaii," which could indicate 128 ROPs. The "Vega 10" ASIC features a 2048-bit HBM2 memory interface.

Update: AMD stated that the die-shot appeared in one of its marketing slides, but may not be real.

If you look closely you will see the captive vega. It has been rumored that one day people will even see it in the wild.

128 ROP's. Now, that's interesting. It was ROP's that were somewhat lacking in the past on Radeons. It seems they've gone full force with it here.

It is on the invisible released in H1 board.

128 ROPs mean ROP decoupling is implemented.

Hardocp said it was a fake shot... go on their site to see. Confirmed by and employee apparently.

Waiting for it and waiting. Released then wait for review benchmarks then wait for custom PCB's. Wonder if i'm gonna buy that thing this year? X-mas maybe :/ Hope the wait is worth it.

So double the ROP's, double the Geometry Engines, AND 50% more compute than Fiji. Then throw in 40% better memory compression.


Yeah I mean this will easily compete with the 1080 Ti. Will likely match the Titan XP if they can hit 1.7GHz and 512 GB/s in the gaming cards.

Isn't it obvious? It's just a normal picture, taken with a normal camera.

I seem to recall Raja holding a supposed Vega chip that looked pretty close to this.

This part was covered (see pic) but one could easily see the shape of the chip, and it's quite similar to this, IMO.

Yep, only the HBM stacks are missing from this one.

Look a bit more closely @ the pic from OP ...

So, possibly smaller than 1080Ti after all.
If so, not beating it won't be such a big deal.

I'm not that stupid. :) I meant that post from you, my bad.
