We already know the Xbox Series X is going to be significantly faster than Microsoft's current consoles, but in a blog post by Xbox head Phil Spencer, the company revealed a few more details about how big of a leap it's going to be. Most notably, Microsoft confirmed that the Series X will feature up to 12 teraflops of GPU performance. Previously, the company only vaguely said it was twice as fast as the Xbox One X, and four times more powerful than the original Xbox One. The new console will be powered by AMD's Zen2 CPU and RDNA 2 GPU architecture, the latter of which isn't yet available on PCs.
