The Card


With all the accessories out the way we get onto the good stuff, the water cooled X1900XTX TOXIC graphics card.



We can see that the design almost works like a dual card solution with the X1900XTX going into your standard PCI Express slot and making room for the water cooling unit in another.



While it's not a huge block it looks very comfortable on the X1900XTX. The block is secured extremely well as you would expect as its going to be shipped all around the world.



Just to the left of the block we have our ATI Rage Theater chip, something we haven't seen on a X1900XTX for a long time as most are covered via the massive ATI reference cooler. The ATI Rage Theater chip gives us VIVO which we know is included thanks to the cables being in the box.



The front of the box mentioned that the two DVI ports support Dual Link DVI for owners of 30" LCD monitors. Dual Link DVI is a feature that is standard in the X1K series of cards from ATI.



Turning the card over, we can see a very typical back side - serial numbers, circuitry and a bracket holding in this case, the water block in place.


Something that we wish PowerColor did but Sapphire have done is include memory sinks. This is great and while it's arguable for the need for heatsinks on DDR3 memory, there is no doubt that it won't cause any harm. With a fan running through the system it is going to help keep them cooler and hopefully help with overclocking, which is what you're going to want to do with a card like this.


The default core clock speed on the X1900XTX comes in at 650MHz but Sapphire has moved this up to 675MHz. Memory default clock speed is 1550MHz DDR and Sapphire has given it a small bump to 1600MHz DDR, which is excellent since the memory is no longer actively cooled.
