ATI Radeon HD 2900 XT Review

ATI Radeon HD 2900 XTX (Cont’d)

This video card uses 16 GDDR3 256-Mbit 1 ns chips from Hynix (HY5RS573225AFP-1) as you can see in Figure 12, making the 512 MB of memory this video card has. These chips can run up to 2 GHz (1,000 MHz x 2). Since on this video card the memories were running at 1.65 GHz, there is huge 20% headroom for overclocking the memories inside their specs. Of course you can even try pushing them above their specs.

On Radeon HD 2900 XT there is a Rage Theater 200 chip, in charge of video capture function of this card (VIVO).

In Figure 14, you can see the HDMI adapter that comes with the card. One of the new features of the new Radeon HD 2000 family is the built-in support for HDMI (which is a new kind of digital video connector), with support for digital audio on the same connector (several video cards providing HDMI output does not provide digital audio output on the same connector).
