And the games will run on Linux using Vulkan. I find that pretty awesome.
Still a great thing for Linux and Vulkan. Too bad Sony refuses to support them on its PS consoles.
Plenty of extensions to choose from.
Stadia's specs per Google:
Custom AMD GPU with HBM2 memory and 56 compute units capable of 10.7 teraflops
16 GB of RAM with up to 484 GB/s of performance
Radeon MI25's specs:
16GB of HBM2 memory at 484 GB/s with 64 compute units capable of 12.29 TFLOPs
12.29 * (56 / 64) = 10.7.
So this is almost certainly just MI25 chips with 1 or 2 bad 'cores'. Aka, the reject pile. From last generation, at that, since the current gen MI50 & MI60 are both 1TB/s HBM2 memory.
The multi-gpu part maaaaay be custom using the Instinct's extra interconnects instead of what used to be consumer Crossfire. But multi-gpu in consumer space is almost entirely dead, and nothing seems to suggest any developer would do anything for multi-gpu in this platform, either.
Much like web apps, YouTube, Netflix etc. today already work flawlessly on Linux, so will gaming too with this development. For most people, the browser is already the only "native" desktop application they use on their computers.
Web apps and web video finally made the Linux desktop viable, but also irrelevant in the bigger picture.
