In Figure 1 you can see the HIS R9 380 IceQ X2 OC 4GB video card (the actual card we tested is an OEM sample, so it hasn’t the stickers at the cooler.) It is a dual slot video card with a twin 90 mm fan cooler, and it is 10.6 inches (270 mm) long.

Figure 5 shows the Radeon R9 380 with its main cooler removed. It is a bit cooler with copper base, five heatpipes (three 6-mm and two 8-mm) and two 90 mm fans. Besides the main cooler, there is also a heatstink on the voltage regulator transistors. The memory chips do not touch the cooler.

In Figure 6 you see the R9 380 with the voltage regulator heatsink removed. Notice that there are eight memory chips, and the voltage regulator has five phases. At the center, the “Tonga” chip, which is manufactured under 28 nm technology.

Figure 7 shows one of the memory chips of the Radeon R9 380. It is a SKhynix H5GC4H24AJR-T2C chip, with 4 Gib (512 MiB) capacity and 5.0 GHz maximum clock, which means the memory is already overclocked at this video card.
