x1950 review

That mem B/W is certainly a killer. I have a feeling ATI knew and released them just ahead of the competition so they didn't need to use 800+mhz mem speeds. Which 1.1ns will do.

Wonder what this GDDD-4 will clock to 2.2ghz? 2.4?

I see 16k easily, 18k with water and *possibly* 19/20k when people get these on dry ice with 1000mhz core and 1.3ghz mem clocks etc.

I think the X19x0s best core:mem ratio is something like 5.5:8.

Starting at 500/600, 2005 is about 9.5k
500/700 its 10k yet 600/600 is still around 9.7/8k
500/800 is pushing 10.5k and 600/800 is pushing 11k

Complex beasts the X19x0s are

I have noticed this.

Upping the memory clock by a tiny amount say 50mhz gives a huge boost in synthetic benhcmarks at least, whereas upping the core although increases the score it doesn't by the same degree as an increased memory clock.

I believe this is all down to how efficient the ring bus memory controller is. However it is only efficient when its coupled with lightning fast memory (could explain why the X1800XL wasn't as quick as most people had hoped)

I agree, Firstly we will not have DX10 untill Vista...the Vista Beta I played with seemed a long way from the Polished final product. DX10 they seem to be talking about 10.1 already ! I would think we are talking getting on for a Year for Vista/DX10.* and a couple of Years for mainstreem DX10 games and the games manufactures would be shooting themselfs if these games could not run in DX9 because even then maybe only 10% of gamers would have DX10 Kit.

Anyhow, I cannot remember Playing a Brand new game on my at the time new PC and being able to run that game at Max settings, so this situation will I'm sure continue
