EVGA, a well-known graphics cards supplier from the <%BANNER[article]%>USA, released the fastest version of its GeForce 7800 GTX graphics card with new cooling and increased clock-speeds. The company claims that increased working frequencies were possible thanks to new cooling system.

EVGA’s e-GeForce 7800 GTX KO Edition graphics card equipped with the company’s new ACS3 (Asymmetric Cooling System3) increases clock-speed of the graphics processing unit (GPU) to 490MHz (up from 430MHz) and memory speed to 1300MHz (up from 1200MHz). To date, these are the highest clock-speeds of NVIDIA GeForce 7800 GTX-based graphics card. Furthermore, the company’s documents imply further overclocking potential of the graphics card.

The new graphics card is outfitted with 256MB GDDR3 memory, two DVI-I ports, VIVO/HDTV connector and is designed for systems featuring PCI Express x16 slot.

The manufacturer said that the new ACS3 design combines asymmetric fan placement, large heat-sinks, heat pipes as well as certain new materials that dissipate heat at a whole new level. The company said that the new cooling system has been granted a patent for its design.

The new ACS3 cooler fully encapsulates the board, giving it rather exotic outlook and protecting it against incautious handling. However, a cooling system that covers the whole board may have its drawbacks: large radiator on the backside may prevent proper dissipation of heat at least in some computer cases.

EVGA said that e-GeForce 7800 GTX KO Edition graphics card will be available through most online e-tailers for the price of $599, similar to NVIDIA’s officially recommended pricing.

NVIDIA GeForce 7800 GTX graphics chip features 24 pixel pipelines, 8 vertex pipelines and consists of more than 300 million transistors. By contrast, its top-end predecessor – GeForce 6800 Ultra – consisted of 220 million of transistors and had 16 pixel and 6 vertex processors. NVIDIA said its new graphics chip is aggressively more efficient than the previous-generation product, which was proved by X-bit labs’ measurements: by having more transistors and 30MHz higher clock-speed, the new chip consumes just 3W more than the former top-of-the-range product and delivers up to more than 50% performance improvement in graphics intensive games.
