The latest Xbox consoles are the Xbox Series X and the Xbox Series S, which were released in November 2020. The Xbox Series X is the fastest and most powerful Xbox ever, with 4K gaming at up to 120 frames per second and 12 teraflops of processing power. The Xbox Series S is a complete digital gaming system and the smallest Xbox console yet, with quick resume, hardware-accelerated Direct X Raytracing, and gaming at up to 120 frames per second. Both consoles feature the Xbox Velocity Architecture, which provides next-gen speed and performance with a custom SSD and integrated software. They also offer backward compatibility, allowing players to play thousands of games from four generations of Xbox.
