Virtualization doesn't work like that. The way instructions need to be assigned and executed in the complex GPU pipelines, each with different burst times, data fetches etc. would mean that each "half" would have far less computing power than it is theoretically available. And it would probably be readily noticed from frame time spikes and latency, a bit like what happens with dual GPUs but worse. Not to mention that comercially speaking, two GPUs half the size of a larger one would have been a cheaper alternative considering how the costs for larger dies scale. Of course, I'm not saying is impossible that it could have happened, maybe Google did invest a lot on GPU resource scheduling and sharing (to little results), but it would seem super sloppy and amateurish even for the standards of the Stadia launch. |
Well looks like you're indeed correct, Eurogamers says shadow of the tomb raider is native 4k on stadia. So they are not splitting the performance. Why stadia have so much worse performance then 10,7TF vega gpu we can only speculate. It can be cooling as you said and porting the games to stadia might be difficult. Can also be the OS Linux as looking at benchmarks there, games seems to lose between 5-20% performance.
So could be any of those 3 things I mention or maybe all of them.
