In Figure 6, you can see the video card with its cooler removed. It uses the AMD reference design. There is a voltage regulator with three phases for the GPU and one phase for the memory chips. The phases for the GPU use ferrite-core coils, but the phase for the memory uses an iron-core coil. All capacitors used on this video card are solid.

The reviewed video card uses four Hynix H5GQ2H24MFR-T2C GDDR5 chips, each one storing 2 Gbit of data, making the 1 GB of m
emory available on this video card. Each chip is connected to the GPU through a 32-bit lane, creating the 128-bit datapath that is available. These chips can run up to 5 GHz. On this video card, they are accessed at 5.2 GHz, so they are operating 4% above their official clock rate.
