What The Hell Is A Teraflop Anyway?

The teraflop seems to be the hot, go-to spec for marketing how powerful a console is, but how much does it actually translate to gaming performance and graphical power? Well, there are certainly other things to look at, such as CPU power.

There is no direct, linear relationship between in-game performance and computational power as measured by teraflops, and while we can get some idea of relative GPU performance, this only really works when comparing different graphics hardware based on the same core architecture. And even then, a GPU with, say, a 40 per cent advantage over another will not see that advantage scale in a linear fashion in terms of pure performance. The capabilities of a graphics processor also rely on more than just computational power too - memory bandwidth in particular is of key importance.
