It seems like a bad metric to use but isn't there still some use to it making it not outright useless? Like comparing the teraflops of the Series X and Series S easily conveys the really big power difference between the two which is useful.

Except we have established that, whenever there is any difference in hardware, Teraflops isn't comparable... Because the ratio of compute to say... Memory capacity/bandwidth/caches and more is different.
There is literally no scenario where you can compare a 1 Teraflop part to a 1 Teraflop part, unless the entire system is *exactly* the same, right down to the transistor... And that never happens.
For example, the Series X has 12.1 Teraflops @560GB/s of bandwidth.
So to scale that downwards linearly... The Series S is 4 Teraflops, so it's bandwidth would need to be about 186GB/s I.E. Exactly 1/3rd, but it's 225GB/s. - So it's "FPS per flop" will be different to the Series X.
And this is why Teraflops is bullshit and a useless metric.

Easily conveying power difference to people is useful which teraflops can do in the right circumstances since while there is inaccuracy it does still give a general idea of the power gap between the two. The inaccuracy does still make it a bad metric though so what metric would you suggest be used instead?
