On power and speed, Spencer points out the Series X’s custom AMD processor, capable of 12 teraflops of GPU performance, which he says will result in higher framerates and larger worlds. Alongside that, variable rate shading support will allow developers to prioritise how effects are applied to their games, resulting in “more stable frame rates and higher resolution, with no impact on the final image quality.” Spencer also says that hardware-accelerated DirectX raytracing willbe a first for consoles.
This is confirms a past leak that said Series X would have 12 teraflops. That leak also said that the PS5 would reach 9.2 teraflops (although that latter point remains unconfirmed).
It’s a jump from existing platforms: PS4 Pro has 4.2 teraflops, Xbox One X has 6, and Google Stadia is capable of up to 10.7 (but that’s tempered by your internet speed).
Teraflops are a measure of trillions of Floating Pointing Operations Per Second (FLOPS). Essentially, this is a measure of how many complex calculations your machine can handle every second, allowing for more high-quality graphical output – in theory.

This is just one measure of console power, however, and doesn’t take into account storage speed, CPU power or RAM – essentially, teraflops are a useful way of indicating an element of console power, but not the be-all and end-all.
If you want a more complex rundown on just what a teraflop is and how, er, floppy(?) previous console generations have been, IGN Executive tech Edtor Bo Moore went into more detail in a recent episode of Next-Gen Console Watch:
