Diamond and Extreme PC bring us the first 1GB HD 2900 XT!

Posted By: Steve McBarnes - 11:08:23 Wed, June 13, 2007

If you want a kick ass high-end Radeon (and you happen to have $600) please go buy this right now! Diamond is the company cranking this beast out but the card has the Extreme PC style and swagger. The card features clock speeds of 825/2,100 (stock HD 2900 XT GDDR3 is 743/1,650), and 1GB of GDDR4 which gives the card 146GB/sec of memory bandwith. This thread from the [H]ard|Forums has some nice pictures of two of these cards in CrossFire inside a wroking computer. This card is mucho powerful and I can wait to see it compared to the 8800 GTX or 8800 Ultra in a game like Crysis or Bioshock.

When I made the following chart I did factor in Shader Clock speed. Crap! I was going to put in a price column too. I guess there isn't enough room anyway.

A chart I made.

Wow... higher clock speeds ( memory clock I mean ) than anyone ever managed to OC out of a 512MB GDDR3 one. I wonder if there is some more room on this card left to OC. I wonder if this will beat the 8800 GTX though. According to the link I posted before on the HD 2900 XT comments it should, but I wonder how it'll compete against the 8800 GTX/Ultra in BioShock and I'm not sure if that link was correct. And also... 146 GB/sec... damn, that's high.

From what I heard its also got 1GB of GDDR4, I think the clocks are higher than Diamond.
Sapphire water cooled gpu's are also not as thick.

I wonder where the 146GB/sec came from when the ram clock is 2.10GHz... it's 134.4GB/sec.

If it doesn't have 1024 bit memory bus, and only eats 10W, it ain't that impressive.

Lol 1024bit memory bus... that's probably coming with the G92 and R700 or w/e , if not even later .
146 GB/sec ... they either mistyped it OR they made the memory bus wider .
