Microsoft confirmed the GPU inside the Xbox Series X is based on AMD's RDNA 2 architecture with 12 TFLOPs of performance.
At 12 TFLOPs, the GPU inside the Xbox Series X is a tad faster than Nvidia's GeForce RTX 2080 Super, and just a bit behind a 2080 Ti, currently the best graphics card for gaming.
Here's a rundown of graphics cards from both AMD and Nvidia in terms of TFLOPs:
- GeForce RTX 2080 Ti (Turing TU102)—13.45 TFLOPs
- Radeon RX Vega 64 (Vega 10)—12.66 TFLOPs
- Xbox Series X (Navi - RDNA 2)—12 TFLOPs
- GeForce RTX 2080 Super (Turing TU104)—11.15 TFLOPs
- Radeon RX Vega 56 (Vega 10)—10.54 TFLOPs
- GeForce RTX 2080 (Turing TU104)—10.07 TFLOPs
- Radeon RX 5700 XT (Navi 10)—9.754 TFLOPs
There probably will not be a direct equivalent on the PC. However, it's a safe assumption that we will see both slower and faster variants in graphics card form. Given what Microsoft has just revealed, there is every reason to believe that upcoming Navi cards will be equal to and potentially faster than Nvidia's current top offering in the consumer space. At least until Nvidia rolls out its next-gen cards as well (Ampere).
