Of course there are still many questions. We do not know what Stadia will cost or how well it will fare with millions of players slamming Google servers (the Project Stream beta was at least solid). But after many false starts in game streaming, Stadia feels like the brave momentum that really makes it stand out. This may seem surprising, since it comes from a company that does not have much experience with games yet. In the past, however, many of the biggest shifts in the industry came from newcomers: Sony turned out to be a viable upgrade to cassettes with the PlayStation on CDs, and Microsoft showed the importance of a robust online service with Xbox Live. Each of these companies has used their know-how to change the gaming landscape. Therefore, it makes sense that Google would bring the streaming to the point. It requires a deep understanding of the Internet and experience in delivering complex services to a variety of devices.
For years streaming games over the Internet has seemed like a dream. OnLive caused a sensation a decade ago to burn out a few years later (Sony has lifted its patent backlog). Gaikai was a direct competitor that Sony used to develop its PlayStation Now and Remote Play. Recently, we saw NVIDIA's downfall with GeForce Now – a solid service that is constantly in beta. There are also smaller companies like Blade and Parsec trying to make a name for themselves. Microsoft says it is working on its own game streaming solution, Project xCloud, from which we expect more details at E3.
While all of these services basically do the same thing (run titles that run on remote servers over the Internet), Stadias reach is at a whole other level. Google indicates that servers with custom CPUs and AMD GPUs operate at 10.7 teraflops that conform to the NVIDIA GTX 1080 Ti. By comparison, the Xbox One X, currently the most powerful console, has six teraflops. The company claims that Stadia will support up to 4K HDR at 60 frames per second, which today only gaming PCs can achieve. It will also keep an eye on 8K 120+ FPS, which today is not supported by any game. To cope with more demanding games, Stadia can seamlessly use multiple servers and GPUs. It also requires SSDs from the server class, which means your games and levels load faster than any console. Basically, you do not have to worry about specifications anymore.
