A 5900XT will OC to 50-75MHz higher than a 5800U?! If that is what you're trying to say, I'm doubting "practically every" 5900XT runs at 550/1100 or 575/1150.
If you're trying to say most XTs OC to near 5900NU speed, sure, I buy that, but that still puts them below the 5800Us in the benchmarks I posted.


Nope. I'm Saying a 5800 loses its fill rate advantage big time by OCing a 5900, Because with a higher memory bandwith you get more more Fill Rate per mhz Than you do with a 5800.

a 5900 @ 475/900 hits a higher single texturing fill rate and practically equal Multi Texturing fill rate than a 5800 Ultra in most circumstances.

Due to having more memory bandwith,

You lose a lot of effiency of core with a 5800 due to memory bandwith bottleneck.
