Hi all,
I currently have a X1900XTX with a cross fie capable motherboard.
I would like to get another card.
I was wondering if I could use the new X1950 CrossFire Master Card?
Or am I stuck with the X1900 Crossfire Master Card?

Thanks in advance

Best bet is to send an email to ATI and ask a tec.

The way things seem to go if you wait 30 days there will be a new card out anyhow!

Have you run benchmarks on both cards yet and if so what did you find?

Thanks for the reply, I'll shoot an email off to ATI.
I currently only have the X1900XTX, I'm on my work lappy at the momemt, but I'll post sum bechies when I get home tonight.

I don't think the X1950 is out in Australia yet, so I was just thinking adhead.

Anywho
Cheers

even if you got the 1950xt as far as my knowledge it would only be as fast as your second card, therefore proving pointless to even get the 1950xt

From memory, the X1950 master card runs at the same speed as the X1900XTX
Where the X1900 Master Card runs at the X1900XT level.
I could be wrong.

I will check

Seems like the only difference is the Ram speed.

However due to the core running at the same speed as the X1900XTX it could be beneficial over buying a X1900 Crossfire Master Card. What do you guys think?

I do not see the problem with running a x1900xt master card. i run 2 7800gt's and i have a more then 40% boost in performance in sli mode.try 2 x1900xt,you might be surprised.

The cards do not run at the same speeds, despite early speculatiuon and restrictions to the contrary. Both cards will run asynchronously at their max. The main thing is that they have similar design, and most importantly that ATi enables support for that combination in their drivers.

The X1900 and X1800 couldn't be paired due to major fundamental differences in their design, but the X1900 and X1950 would be similar in architecture only different in clock speeds (and ram but that's unlikely to alter things).

I think it would be wise for ATi to enable X1900+X1950 crossfire, but that doesn't mean it will happen, as many previous logical and benificial things have not occured for one reason or another (usually marketing though).

Anywhoo, X1950+X1900 will both operate at their stock speeds, however if there were a scale difference like 6 equally functional groups versus 4 equally functional groups, then the second card would not use the 2 additional functional groups in Xfire. Even this shouldn't be an issue technically, but with the way ATi have implemented it this is the way it currently works.

I was thinking the exact same thing. But as we all know, companies would rather make you buy 2 new cards rather than enabling backwards compatibility support.
I could always just wait until the X1900Master card comes down in price. But Australian prices can sometimes be a bit strange. More than likely the current models will stay at the same price, and the newer cards will be priced even higher!
