RDNA 2
A GPU microarchitecture introduced by AMD in 2020, used in the PlayStation 5, Xbox Series X and the Radeon RX 6000 series graphics cards. It supports FP16 and INT8 operations but lacks dedicated matrix multiplication units.
Core Facts
RDNA 2 is a GPU graphics architecture launched in 2020 that introduced hardware ray tracing support for the first time and was used in the RX 6000 series desktop graphics cards and the custom APUs in the PS5 and Xbox Series X.
The PS5 uses a custom AMD Zen 2 CPU and RDNA 2 GPU, its system software is based on a FreeBSD derivative, and it uses a custom system called Orbis OS.
The PS5 is equipped with a custom AMD APU, including an 8-core Zen 2 CPU and a 36-CU RDNA 2 GPU, with 16GB of GDDR6 shared between VRAM and system memory, and supports FP16 and INT8 computation.

FSR 4.1 initially relied on RDNA 4's AI acceleration units to run its ML models, and bringing it down to RDNA 2 means AMD must switch to an inference path or hybrid approach with lower compute requirements.
The PS5 uses a custom AMD Zen 2 CPU and RDNA 2 GPU, its system software is based on a FreeBSD derivative, and it uses a custom system called Orbis OS.
The PS5's GPU is based on the AMD RDNA 2 architecture, with theoretical floating-point performance of about 10.3 TFLOPS.
