Introduction (Cont’d)
Hardware Secrets Golden Award

We removed the video card cooler to take a look. As you can see in Figure 5, the cooler base is made of copper, using two thick copper heat-pipes to connect the base to the aluminum fins.

In Figure 6, you can see the video card without its cooler. It uses eight 512-Mbit Qimonda IDGV51-05A1F1C-40X GDDR5 chips, making its 512 MB memory (512 Mbits x 8 = 512 MB). These chips have a maximum transfer rate of 4 Gbps (“40X” marking), which is equivalent of a 4 GHz GDDR5 clock or 1 GHz (4 GHz / 4) real clock. Since on this video card the memory was running at 900 MHz, there is a good 11.11% headroom for you to overclock the memories with them still inside their specifications. Of course you can always try pushing them above their specs. In Figure 7 we provide a close-up of the GDDR5 memory chips.

In Figure 8, you can see all accessories and CDs/DVDs that come with this video card, which includes a 2 GB USB drive (limited time offer). With the accessories that come with this card you can convert the video output to VGA, HDMI, component video and composite video, plus the DVI and S-Video connectors already present on the product.

Now let’s compare the Radeon HD 4870 specifications to its main competitors.
