Gigabyte Technology has now added to its website a second Radeon HD 7970 graphics card, the (previously-leaked) model codenamed GV-R797OC-3GD which features a dual-slot, triple-fan cooler, a custom PCB, and a GPU clocked at 1000 MHz (the standard frequ…
To spice up the holidays of Nvidia fans, EVGA has developed a couple of ‘new’ GeForce GTX 580 Classified cards, two ‘Ultra’ models which come with GPU/shader/memory clocks of 900/1800/4212 MHz (previously-released GTX 580 Classified cards topped out at…
XFX is ready with its Radeon HD 6790, too. The XFX HD679XZDFC is a completely in-house designed HD 6790 implementation by XFX, including a custom PCB and cooler, which can also be found on its HD 6800 series models. Essentially, HD 6790′s electricals on this particular board match those of the HD 6870. The PCB uses a 4+2 phase VRM for the Barts LE GPU, which packs 800 stream processors and 256-bit GDDR5 memory interface holding 1 GB of memory; power is drawn from two 6-pin power connectors.
Moving on to the cooler, it uses a large aluminum fin array to which heat is fed by three copper heat pipes that make direct contact with the GPU. It is ventilated by two 80 mm fans. Display outputs resemble those of the HD 6870, more than those of the HD 6850; there are two each of DVI and mini-DisplayPort 1.2, and one full-size HDMI 1.4a. The card can pair with another (probably any Barts-based card) for 2-way CrossFire. Expect it to be out on Thursday.

After showing off a monstrous DirectCu II cooled Radeon HD 6970 at CES, ASUS released pictures of another card which probably couldn’t make it to Vegas. The GeForce GTX 580 DirectCu II from ASUS is just as beastly as its Radeon cousin. It uses a completely in-house design, with custom PCB that uses a strong VRM; and a triple-slot cooler which uses copper heatpipes that make direct contact with the GPU. The PCB uses an 8-phase GPU and 2-phase memory VRM. Whereas the reference design draws all memory power from the slot, the ASUS version has shifted one memory phase to external for improved overclocking. The VRM makes use of high-grade components, including an NEC-made proadlizer to condition power for the GPU.
The DirectCu II cooler uses a large aluminum fin array to which heat is conveyed by five heatpipes that make direct contact with the GPU. Two 100 mm fans are in charge of ventilation. The rear panel consists of two DVI, and one each of DisplayPort and HDMI. The card is bound to have factory overclocked speeds, with room for more overclocking. The cooler, though large and with two fans, is tested by the company to be quieter than NVIDIA’s reference design cooler. The GeForce GTX 580 is NVIDIA’s flagship DirectX 11 GPU. It packs 512 CUDA cores, and connects to 1536 MB of memory over a 384-bit wide GDDR5 memory interface.

Club 3D unveiled a ‘custom-designed’ graphics card based on the ATI Radeon HD 5850 GPU, being sold as the Overclocked Edition. The design of this accelerator resembles that of PowerColor’s PCS+ series HD 5800 series accelerators, pointing back at its source. The card features a custom PCB and cooling solution which makes some smart cost-cutting in return for out of the box higher clock speeds. The GPU and memory are clocked at 760 MHz and 1050 MHz (4200 MHz effective), respectively, against reference speeds of 725/1000 MHz.
The cooling system involves a large heatsink with aluminum fins, to which heat is conveyed by four heat pipes. A centrally-located fan blows air on to it. The Radeon HD 5850 GPU is DirectX 11 compliant, features 1440 stream processors, and connects to 1 GB of memory on this card, across a 256-bit GDDR5 memory interface. The display connectivity, we presume, resembles that of the reference design, with two DVI-D, and one each of HDMI and DisplayPort connectors. Club 3D is yet to announce its price.
