it was clearly more technical and complicated than just comparing fill Rates. You simply have to google Xenos vs X1800 to see that. People with wayyy more knowledge about this than us usually came to the conclusion of X1800 to X1900 performance.

Would be nice if next gen consoles performed as well as Xenos did for its time. But that’s looking like a pipe dream these days.
altho I do think They’ll compare better vs PC than Xbox One did at launch
.....Link is pointless to the point..... You have no understanding why.....
With the Xenos one main thing it had over the X1000 series was its unified shader processors... its power didn't allow it to match or outperform the x1800 or x1900 series when it came to pixel pushing power or texture fill rate. The only aspect that allowed the 360 gpu to perform in the realm of the x1800/x1900 or Geforce 7800's was when the game took advantage of the custom API that bypassed the limitations of pre DX10 API which allowed much more draw calls over Direct x 8 or early versions of DX 9. Or depending if the game was heavily shader based vs geforce 7's.
But the fact is once you brute forced through DX9 limits with a strong enough cpu, gpus like the non-unified shader Radeon X1950 Pro out performed the 360 with games like Crysis 2 Even with all the optimization and maturity the 360 had by 2011.
These current consoles are using semi-modified pc hardware with coding and infrastructure very similar to the PC environment, which is why we are able to almost directly compare equivalent gpu hardware between the two platforms.
In other words, Xenos performance was comparable to a X1800 XT at launch (that was a $550 dollar videocard)
