ATI Radeon R600

The long awaited and hugely anticipated ATI card is finally here. We have been given access to information and media documenting ATI's first DirectX10 graphics card. The technical specifications look promising, with some features never before seen on a GPU, making these cards innovative and one of a kind.

This article is designed to run through a little bit of the technical information without confusing the hell out of you. It is a short and sweet introduction into r600 and it's architecture and is meant to cover it in an understandable way.

The HD 2900 Series has a massive transistor count of 700 million which is slightly more than nVidia's G80 which has 681 million. The R600 die is manufactured on 80nm process technology, slightly lower than nVidia's G80 which uses 90nm. There are already plans to possibly reduce this to 65nm, which will mean lower power consumption & more importantly (for the overclockers) lower temperatures.


Interesting Extra Features

Before we launch into the technical jargon let's take a look at the extra features that ATI have implemented on the 2x00 cards...each card in the 2x00 series has both HDMI connectivity as well as 5.1 Audio.

A lot of people have been questioning the 5.1 Audio, but it really makes sense if you want to build a HTPC and makes it a all-in-one solution.


Clock Speed, numbers and more

Let's take a brief overview of the actual clock speeds of the 2x00 family. ATI have entered with three initial SKU's giving quite a breadth to their releases. The 2900XT is the card that tops the range, with the 2400 and 2600 filling in the gaps. I'm sure we will see more from AMD/ATI in the future, however.

I'm sure a lot of people have already read articles about these cards aswell as seeing the current benchmarks. I think we will see an improvement on benchmarks and general performance as new drivers are released.
