The technology behind the Radeon X1950 Pro

As mentioned on the previous page, the X1950 Pro card is based up-on a graphics chip called the RV570 as designed by ATI. Specifications of the RV570 core are cuddling up into 12 pipelines and 36 pixel shaders with a 580 MHz core clock. Memory will be clocked at 1.4 GHz and have a 256-bit interface.

The standard Radeon X1950 Pro cards will be equipped with either 256 MB or 512MB of graphics memory and sport either a single or dual slot cooler (depending on the manufacturer's choice). The ATI Radeon X1950 Pro is also ATIs first card with internal CrossFire compatibility for dongle-less CrossFire connectivity. ATI claims performance of the Radeon X1950 Pro will be faster than the GeForce 7900 GS; and yes it is.

In short, the reference model cards will work at 575-600MHz core and 1400MHz memory and will be pushed over a 256-bit memory interface. Also an interesting fact is that the Radeon X1950 Pro and X1650XT have both launched as 80nm products which results in a smaller die size, lower power consumption and thus less heat as you can lower the voltage a little.

The HiS board & the Bundle

What's in the box? Well it doesn't matter really as you are buying an HiS product so you'll know for sure you'll receive anything needed to get this puppy up and running in no time, whatever your intention with the card may be. HiS have included everything you need to setup the card and play a game.

• One lovely graphics card
• The game Flatout
• Power DVD
• DVI to VGA adapter 2x
• DVI to YPRPB Adapter (HDTV component)
• Svideo & composite cable
• Crossfire connectors
• Quick install manual

I have nothing much to say other then it's a 100% reference based card up-to the transistor similar. What obviously has been changes is the all new IceQ3 cooler. And since we have the Turbo model it's faster clocked compared over the reference clocks, the core is bumped up at default towards 620 MHz and the memory a 100 MHz faster at 1480. Granted It's not a huge difference .. but it surely helps albeit a little.
