Xbox Series X full specs were today detailed thanks to a piece by Digital Foundry.
We already knew the next-gen console could produce 12 teraflops of power, but know we know the console’s eight CPU cores are speedy — 3.6Ghz speedy — with hyper-threading enabled. When hyper-threading is off, the cores can operate in 3.8GHz mode.
“12 TFLOPs was our goal from the very beginning. We wanted a minimum doubling of performance over Xbox One X to support our 4K60 and 120 targets. And we wanted that doubling to apply uniformly to all games,” Microsoft’s Andrew Goossen said.
“To achieve this, we set a target of 2x the raw TFLOPs of performance knowing that architectural improvements would make the typical effective performance much higher than 2x. We set our goal as a doubling of raw TFLOPs of performance before architectural improvements were even considered – for a few reasons. Principally, it defined an audacious target for power consumption and so defined our whole system architecture.”
Finally, for those curious about physical space and weight, the Xbox Series X is 11.81 inches high by 2.36 inches long by 9.4 inches deep. It weighs 4.45 kg.
Full Xbox Series X specs — and a comparison to both Xbox One X and Xbox One S — can be found below.
