Google has released the following data for Stadia.
- Custom 2.7GHz hyper-threaded x86 CPU with AVX2 SIMD and 9.5MB L2+L3 cache
- Custom AMD GPU with HBM2 memory and 56 compute units, capable of 10.7 teraflops
- 16GB of RAM with up to 484GB/s of performance
- SSD cloud storage
Google says that this hardware can be stacked, meaning that the CPU and GPU compute is ‘elastic’, so multiple instances of this hardware can be used to create larger scale games. This configuration is referred to as a ‘first-gen’ system, using Google’s datacenter hardware to evolve over time instead of the need for users to upgrade their equipment.
At the current time, we’re not sure if the 16GB of memory is system-wide, or for GPU VRAM only. Stadia’s bandwidth is confirmed and is a 100% match for the HBM2 used on AMD’s RX Vega 56 graphics card.
