XFX Radeon HD 7770 Super Overclocked Edition Video Card Review

The XFX Radeon HD 7770 Super Overclocked Edition (Cont’d)

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 memory 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.
