The Xbox Series X has 12 teraflops of GPU performance. Here's what that means. Microsoft confirmed earlier this week that the Xbox Series X has 12 teraflops of GPU performance, double that of the Xbox One X and eight times the amount of the standard Xbox One. You would've seen teraflops mentioned every time there's a new console announcement, but what is it, and why does it matter for gaming? Let's find out. What is a teraflop? A FLOP is an acronym for floating point operations per second. Floating point operations include irrational numbers and decimal points, and they're much more complex than fixed point operations, which are limited to binary integers. Because of the inherent difficulty of floating point operations, they're used to measure the compute power of a particular system. Without getting into the weeds, a teraflop (TFLOP) means the ability to process one trillion floating point operations per second. So when Microsoft says that the Xbox S
