ATI HD2600XT
In terms of features and performance the HD2600XT is a cross between the faster HD2900XT and the budget HD2400XT. The 3D performance of the card is a good deal lower than that of the 2900 card, but it does feature hardware HD video acceleration, something the bigger brother hasn't got.

Much like with the HD2900XT ATI decided to offer several flavours of the card. All of them offer the same features and they only differ in GPU speed and memory speed/kind. The unit we will be testing today is the fastest of the bunch – the HD2600XT with GDDR4 memory.
The HD2600XT bears some resemblances to the X1950Pro, a card that is even today one of the most popular ATI cards available. The cooler, while at first glance very similar to the one found on the reference X1950Pro is in fact a slightly improved version, both in terms of performance and noise. As you can see from the pictures the card doesn’t require any external power as it is able to draw all it needs from the PCI-E bus.
There are no surprises when it comes to the connectors found on the card. The two DVI ports are both dual-link enabled and the TV-Out is HD capable. Manufacturers can chose to supply a DVI-to-HDMI dongle in their packages, as the card is just like the HD2400XT capable of delivering a full HDMI signal.
