google Stadia wants to overturn the video game industry by offering access to AAA titles without expensive hardware. At launch, Majd Bakar, Head of Engineering at Stadia, said Stadia would allow players to broadcast AAA titles at 4K resolution at 60 frames per second, with equipment as rudimentary as a smartphone or tablet. These promises prompted former competitors such as Microsoft and Sony to join forces, but it also seems that Google has suffered too much.
According to an alleged leakage of computer equipment that will feed the infrastructure of Stadia, the latter has recently appeared on the list of products of the Vulkan API group Khronos. The entry describes a "Google Gen 1 Game Platform (AMD GCN 1.5)". Assuming that the platform in question is actually Stadia, the product list reveals crucial information, including the type of GPU it will host.
As you may know, AMD is the leading supplier of gaming chips and is currently developing a new 7-nanometer GPU architecture called "Navi" to power future PlayStation 5 and Xbox "Scarlett" consoles. These custom Navi chips are supposed to be bestial, but based on the list of products, it seems that Google's game product uses a different chip architecture.
Khronos' list indicates that Google will use a "GCN 1.5", synonymous with the 14-nm Vega chipset series from AMD, a bundle released in 2017. Although Vega chips still power many high-end PCs , Stadia will have a hard time keeping its promises using a 2017 GPU as the engine.
Bakar has already promised that Stadia will launch 10.7 teraflops (graphics power), 56 computing units and 8 GB of HBM2 memory capable of running at 484 GB per second. The Radeon RX Vega 56 comes with 56 compute units and 8 GB of memory, suggesting that this might be the GPU on which Google will install itself. But it only delivers 8.3 teraflops of average graphics power.
According to AMD, the Vega 56 is capable of reaching a peak performance of 10.5 teraflops. This is close to what Google has promised, but it should nonetheless that the chip is constantly overclocked, which shortens its life and affects its future performance. And even in this case, reaching 4K resolution at 60 fps seems out of reach.
TechSpot tested the Vega 56 with 25 different games and averaged 43 fps at 1,440 points per second. This type of performance will likely be overtaken by the Navi architecture that should be tuned in at E3 2019, which should replace the game at 60 fps on the consoles.
Dr. Lisa Su, CEO of AMD, confirmed that the PS5 and Xbox Anaconda consoles would receive a custom Navi GPU to usher in a new era of game graphics. The company expects the core chip architecture to be ready by the second half of 2019, and a handful of sources have suggested they will come with unprecedented levels of performance.
Two lots of leaks suggested that the PS5 would be able to contain between 12 and 14 teraflops. These specifications confirm industry rumors that PS5 and Xbox Scarlett devices will reduce Stadia's graphics capabilities. But that does not mean that the game in the Google cloud is doomed.
The company can easily upgrade its system infrastructure with new GPUs over time, improving the performance of its users. But as things stand, Stadia may well be heading for a slightly disappointing launch. This would let the PS5 and Xbox Scarlett play, once they are officially launched in 2020.
Google did not immediately respond to a request for comment.
