PlayStation 5 vs Xbox Series X specs: CPU, GPU, storage and more compared

These specs aren't the full story - but they're still an interesting point of comparison.

In the run-up to the reveal of PlayStation 5 and Xbox Series X, there was intense speculation over the hardware that powers each machine. How many teraflops would each next-gen console possess? Which would have the higher CPU clocks? Would both make use of NVMe storage, and what would external storage look like? Now, both Microsoft and Sony have revealed their core specifications, and we finally have a good idea of what each machine looks like on the inside.

The table below collects the most important specifications for each machine, incorporating CPU and GPU architecture and performance, storage solutions, backwards compatibility and more. These specs aren't the full story by any means, but they're still a fascinating point of comparison - and an important backdrop to the larger discussions around the reveals of the Xbox Series X and the Sony PlayStation 5.
