ATI Radeon HD 2600 XT Review

ATI Radeon HD 2600 XT Reference Model

From the pictures posted in the previous page you could see that Radeon HD 2600 supports Native CrossFire technology.

On thing that is new on the Radeon HD 2000 series is the support for HDMI with digital audio on the same connector. Because of that Radeon HD 2600 XT video cards will come with a DVI-to-HDMI adapter. More information about this feature can be found on our ATI Radeon HD 2000 Series Architecture article.

You could also see from the pictures posted in the previous page, the reference model for Radeon HD 2600 XT uses a big cooler that dissipates the heat produced not only by the graphics chip and the memory chips, but also by the coils (chokes) found on the board. We removed this cooler to take a look and it has an aluminum body with a copper base, see Figure 4.

In Figure 5, you can see this video card without its cooler.

This video card uses four GDDR4 512-Mbit 0.91 ns chips from Samsung (K4U52324QE-BC09), making the 256 MB of memory this video card has. These chips can officially run up to 2.2 GHz (1.1 GHz x 2) and since on this video card the memory chips are already running at 2.2 GHz there is no headroom for overclocking the memory inside its specs. Of course you can always try to push the memory clock above the memory chip maximum official clock rate.
