How is X1800XL be better than X850XT?

post #1 of 13
Thread Starter 
I understand that X1800XL has newer, updated architecture, but if I have an X850XT is clocked at, say, 540/1150, how can an X1800XL do better?

X1800XL supports higher resolution and has some added technology, but it's not like a new DirectX has come out...

The X1800XL is more efficient. It does more for each clock cycle.
Very nice!

Its pretty interesting though that the X1800XL performs almost as well as the 7800GT and its clocked slower than the X850XTPE.

just coz it's clocked lower doesn't mean anything, look at AMD and Intel AMD is usually 30% slower than an equivelent Intel but performs equally...

it does more per cycle and does effects such as AA and aniso much more efficiently. turning on those options doesn't give such a fps hit in games like it would with an x850 (or even a GF7800). plus it has adaptive AA

Does the x1800xl have the same ammount of pixel AND vertex pipelines as the x850xtpe? Im pretty sure they both have 16pp but what about the vertex pipelines? I dont know much about ati.
