The chaps over at VR-Zone has gotten its hands on one of ATI's upcoming Radeon X1950 XTX graphics cards. The card's performance is impressive, and its 1GHz GDDR4 memory seems to give it a sizeable performance advantage over the Radeon X1900 XTX. Here's a taster:
Our testing shows that the X1950XTX is significantly faster than NVIDIA's 7950GX2 at rather common enthusiast in-game setting. This is definitely very appealing for the gamers, especially when you factor in the ability of the card to run true HDR with Anti-Aliasing compared to the 7950GX2 which can't do that, and the fact that the X1950XTX offers [font=Arial,helvetica][font=Arial,helvetica]dual [/font][font=Arial,helvetica]display[/font][/font] without compromising performance while the 7950GX2 has to sacrifice dual GPU performance for dual display. Add the best performing and best looking default [font=Arial,helvetica][font=Arial,helvetica]cooler[/font][/font] found in the market and it really seems ATi has come up with quite a winner this time. It is rather shocking however, to discover that the card actually draws more power than a multi-GPU 7950GX2. Other than that this card seems to have almost everything going for it, even though 3D Mark performance boost is not catching up to the 7950GX2 at 650MHz Core clock. Now it's much of a question of the availability of the cards at launch, and this may be partly affected by the production quantity of the rather new GDDR4 Memory. For gaming enthusiasts, if this card really retails at the USD$399 it is slated to, this is THE loveboat as you won't be able to get the performance for that price looking at any other card than this. It seems that ATi has delivered quite an uppercut to NVIDIA with this!

I might do it too if the RD600 is rumoured to take up THREE pci slots :eek:

Where did you hear that? That would be horrible. :eek: I thought that the R600 was going to be done on the 90nm process so would generate less heat and use less power, like the 7900 series.

Think you mean the 80nm. ;)

I thought the x1950 was gona be on the 80nm to, oh well just be the R600 then. :)

I'm not sure anymore, lol! I just know it's going to made in a smaller process so I am happy. :p

Well the x1900's etc.. are on a 90nm, so if its a smaller one... :p

Really? I thought the 7800/7900 series were on 90nm or 85nm or something, and that the X1900/X1800 series was still on 120nm which was the reason they were so hot and stuff. I could easily be wrong, it's a case of "I swear I read somewhere that..."

Comapring these two,225 mhz increase on the ram does not look that exciting IMO.

Higher bandwidth but will this really rival the GX2?

I doubt it.

Sweet! I never knew the exact bandwidth of the new GDDR4 memory. :eek: No wonder that card it's so bloody powerful, it's 0.9ns too according to the review.

I think the 256MB XT version of the X1950 will definitely be my next upgrade.

Well, it's an almost 25% increase and looks about the same as the memory bandwidth increase between the X1600 and X1800 so it sounds about right to me.
