XFX Radeon HD 5750 Video Card Review

Hardware Secrets Silver Award

Introduction (Cont’d)

We removed the video card cooler to take a look. As you can see in Figure 5, the cooler is very simple, using an aluminum base. It doesn’t touch the memory chips and they have no heatsinks on them.

With the cooler removed you can see that almost all capacitors are solid, which is a terrific feature as they don’t leak (the ones that are not solid are from Elcon, a Chinese manufacturer). Like the memory chips, the transistors from the voltage regulator don’t have a heatsink.

XFX Radeon HD 5750 uses eight 1 Gbit Hynix H5GQ1H24AFR-T2C GDDR5 chips, making its 1 GB memory (1 Gbit x 8 = 1 GB). These chips have a maximum transfer rate of 5 Gbps (“T2C” marking), which is equivalent of a 5 GHz GDDR5 clock or 1.25 GHz (5 GHz / 4) real clock. Since on this video card the memory was running at 1.15 GHz, there is an 8.7% headroom for you to overclock the memories with them still running 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 that come with this video card, basically a quick installation guide, a driver CD, a power adapter for converting two peripheral power plugs into one six-pin video card power connector, and a “do not disturb” sign.
