[ HIS 7950 IceQ Turbo in Detail ]

Whereas the AMD reference designed Radeon HD 7950 measures 27cm, the HIS 7950 IceQ Turbo is slightly shorter at 26cm long. Although this is not a huge difference it will go a long way in making the HIS 7950 IceQ Turbo more ATX case friendly. The HD 7950 GPU is fabricated on a 28nm process, making it possible for AMD to squeeze 4313 million transistors into a 352mm2 die. By default the GPU core runs at 800MHz, 14% lower than the HD 7970, and the GDDR5 memory operates 9% slower at 1250MHz. These are the same core and memory frequencies as the HD 6950. However, HIS’s HD 7950 is overclocked to 900MHz and 1250MHz. The 13% increase in core clock speed should have a positive impact on performance. Whereas the HD 6950 utilized a 256-bit bus, the HD 7950's is 384-bit, boosting the available memory bandwidth from 160GB/s to a considerably healthier 240GB/s. As you'd expect, the HD 7950's core configuration is cut down from the HD 7970. The speedier card has 2048 SPUs, 128 TAUs and 32 ROPs, while the HD 7950 packs 1792 SPUs, 112 TAUs, and the same 32 ROPs (13% less SPUs and TAUs). What makes this HIS iteration unique is its IceQ solution with "Black Hole Impeller". The cooler uses a large 80 x 21.5mm blower fan which is connected to a custom shroud. In front of this fan is a massive heatsink which features four nickel plated copper heatpipes. Connected to the large copper base of the heatsink is a unique RAM heat spreader, which is designed to cool the GDDR5 modules. HIS claims that this cooler is up to 12 degrees cooler than AMD’s reference version. To feed the card enough juice, AMD includes dual 6-pin PCI Express power connectors. This is the same setup used on the HD 6950, 5870, 6870 as well as the GTX 580 and 570 graphics cards. Naturally, the HD 7950 supports Crossfire, so it has a pair of connectors to bridge two or more cards. The only other ports are on the I/O panel where you'll find a dual DL-DVI connector, a single HDMI 1.4a port, and two mini-DisplayPort 1.2 sockets. All HD 7950s support a max resolution of 2560x1600 on up to three monitors. With a multi-stream hub, using the mini-DisplayPort 1.2 sockets, the card can power up to six screens.
