Which graphics processor powered the original Xbox?

The original Xbox used NVIDIA’s NV2A graphics processor.

The NV2A was a customized graphics chip developed by NVIDIA for Microsoft’s first console. It was based on technology related to NVIDIA’s GeForce 3 generation, but it was adapted for the Xbox’s unified hardware and memory design. The chip helped the system deliver advanced 3D graphics for its time.

The original Xbox combined the NV2A with a 733 MHz Intel Pentium III-derived processor and 64 MB of unified DDR SDRAM. Unlike a typical PC, the console used a fixed hardware platform, allowing developers to target one consistent configuration.

The NV2A is often confused with later Xbox graphics hardware. The Xbox 360 used ATI’s Xenos GPU, while Xbox One and Xbox Series consoles used customized AMD graphics technology. Those chips belong to later generations and are not the NV2A.
