The Radeon HD 7770 Black Excellent Overclocked Version Double Dissipation is a video board from XFX boosting the fresh "Cape Verde" conventional Graphic Processing Unit. The card is cooled through the fresh double fan cooling system from the similar manufacturer, which is both sufficient and silent, the Graphic Processing Unit reaching no more than 65 degrees later 15 minutes of stress trying in Furmark. The card arrives pre-overclocked and even has few headroom left without the require of increasing the stock voltage.
As we have looked from AMD’s last slides, throughout the establish of the 7900 serials, the “Southern Islands” line is separated in 3 parts every having dissimilar performances. First we have the “Tahiti”, which is the fresh high end and integrated the Radeon HD 7970 and 7950 cards, “Pitcairn”, which cards are not established now and of course, “Cape Verde”, which hopes at the budget conscious individual, and is meant to bring an excellent balance among power, cost and power consumption.
The representatives of “Cape Verde” are Radeon HD 7750 and 7770 and the card we will appear upon yet is the XFX Radeon HD 7770 Black Excellent Overclocked Version, boosting Dual Dissipation. As the name coments, this example is pre-overclocked and characteristics a dual fan cooling system. Here are the dissimilarities in specifications among the OEM example from AMD and the extending from XFX:
As same as the 7970, the 7770 cards are construct upon the 28nm architecture and arrive with the similar characteristics as the high-end GPUs; from these we can enumerate Eyefinity 2.0, PowerTune, ZeroCore Power, DX 11.1 hardware support, PCI-E Gen iii and so on.
At this level you might say: cool, but what has been decrease then to meet these cost points? Well, AMD has decreases the GPU architecture to 10 compute units and just the memory bus is just 128-bit wide. The smaller brother, Radeon HD 7750 has 512 stream processors and shares the similar to 128-bit memory bus.
