However, with suddenly unexpectedly high yields, and an unfavourable competitive environment, suddenly a glut of chips were on hand, more than they could reasonably move. From these chips new, cheaper products were formed in the shape of the 8 pipelined X800 GT and the 12 pipelined GTO.

Here we take a look at the last hurrah of ATI’s X800 series with two GTO products from Sapphire; the Sapphire Radeon X800 GTO² and X800 GTO Ultimate Edition both have the same basic specifications, but are both catered towards distinctly different users. <a href="http://www.beyond3d.com/reviews/sapphire/gtos/">Click here to read the review</a>.

I'm probably being thick, but are the stated texel rates correct for the clock, texture unit and ROP count on those boards? They seem out by a fair bit.

Not any more! :)

How come the texture rate is 8G if it's not unlocked and just 12 PP:???:

Compared to the 2.0ns RAM on the Ultimate Edition board, the 1.6ns memory on this GTO² card unsurprisingly yielded a far greater RAM overclock, bringing the final clock speed up 80MHz to 570MHz from the 490MHz default.

1000/1.6 = 625

?

Yes, but that depends on DRAM voltage. It probably doesn't have enough juice to get to the rated speed.

Indeed - I was hoping to get more out of the RAM, but that's as high as I could get it stably.

Thanks for editing the texel rate Dave, should have spotted that one! :roll:
