About two weeks after the first pictures of the Radeon HD 7970 DirectCU II TOP graphics made their way to the Web, Asus sent out an official press release announcing the launch of this highly customized graphics card which comes with a 1GHz factory overclocked GPU.Much like its predecessors, the DirectCU II edition of the HD 7970 features a massive tri-slot cooler, a highly customized PCB and a series of other overclocking optimizations.
These include a series of voltage measurement points, a 12-phase VRM circuitry with supper alloy caps and chocks, as well as a special SAP capacitor added to maximize overclocking headroom, according to Asus.
The tri-slot cooling system is also just as impressive, since it uses two 100mm fans sitting on top of a massive aluminum heatsink, while most of the PCB is covered with an aluminum heatspreader.
Asus says its design keeps the core 20% cooler than AMD’s reference design, which allowed the company to push the Radeon HD 7970 over its reference frequencies, so the GPU will be clocked at an impressive 1GHz while the memory will work at 1400MHz (5.6GHz effective).
According to Legit Review, the Asus Radeon HD 7970 DirectCU II TOP should be available online later today and will carry a suggested retail price of $599 (about 456 EUR).
AMD’s Radeon HD 7970 is based on the Tahiti XT core, which includes 32 Compute Units for a total of 2048 stream processors that are joined by 128 texture units, 32 ROP units and a 384-bit wide memory bus.
This is linked to 3GB of DDR5 video memory and the GPU is manufactured using TSMC’s advanced 28nm node, which enables it to be one of the coolest and most energy efficient high-end graphics card around.
