Company XFX is preparing Radeon HD 7970 GE with Double Dissipation cooler

American vendor XFX is about two weeks to release a Radeon 7970 Edition Double Dissipation (model code — FX-797G-TDF). It combines the capabilities of GPU Tahiti XT2 with a higher overclocking potential and the TDP, rather than at Tahiti XT, PCB reference design, but without a single phase power supply (6 +1), and the cooling system in the vaporizing chamber, an array of aluminum fins, PA plate (the same heatsink for the VRM and memory), as well as the two fans standard size 90 mm.



New model will get the recommended for the Radeon HD 7970 GE frequency ratio 1000/6000 MHz for core and chips GDDR5. The graphics chip will operate at 1050 MHz in the load. Recall that the “usual” HD 7970 was limited to regular frequencies 925/5500 MHz and did not support dynamic overclocking.


The configuration of video outputs is almost standard: from the five of DVI-I, DVI-D, HDMI and 2x Mini DisplayPort for some reason excluded DVI-D. The additional power is supplied by one 8-pin and one …
