Amazon’s Luna game streaming service is powered by Windows and Nvidia GPUs

From The Verge: Amazon’s new Luna cloud gaming platform is powered by Windows servers and Nvidia GPUs. Luna supports more than 100 games thanks to this Windows support, allowing developers to quickly move their existing Windows games over to an AWS instance and provide cloud streaming access to subscribers. This backend Windows support also allows publishers like Ubisoft to host their own digital services (Uplay) on Amazon’s Luna platform.

Amazon has confirmed to The Verge that Luna will run on a standard version of Amazon’s EC2 G4 server instance running Windows, complete with Nvidia’s T4 GPUs and Intel’s Cascade Lake CPUs. Nvidia’s T4 is based on the company’s Turing architecture that also powers the previous generation RTX 2080 and RTX 2080 Ti graphics cards. A single T4 GPU (Amazon might be using multiple) provides 8.1 teraflops of performance and support for Microsoft’s DirectX raytracing technology.

What this all means is that it should provide smooth gaming performance at the 1080p resolution Luna currently supports. 4K, which Amazon says is coming soon, might be more of a challenge for Luna on this hardware, especially without dialing down graphical settings in some demanding games.

Amazon’s main cloud streaming rivals, Microsoft and Google, are using entirely different hardware and operating systems for their own cloud gaming services. Google opted for a custom x86 processor and a custom AMD GPU capable of 10.7 teraflops of GPU performance, all powered by Linux. Microsoft is currently using Xbox One S hardware in its server blades, offering just 1.4 teraflops of GPU performance and all running on the Windows-powered custom Xbox OS. Microsoft has confirmed it will move xCloud servers over to Xbox Series X hardware in 2021. Sony also uses custom PlayStation hardware for its own PlayStation Now service.
