NVIDIA GTX 580 slides show new cooling
NVIDIA's GeForce GTX 580 has been previewed again with clues that the cooling will be as important as the performance. The official clip (below) shows the "unreleased GPU" having vapor chamber cooling, which carries the heat away from the graphics chipset through constantly circling water that evaporates and condenses as it reaches the heat sinks. Combined with a dynamic fan system and optimization for multi-card SLI setups, the design should run noticeably cooler and quieter than earlier cards, NVIDIA said.
The company also touted the unreleased hardware as the fastest DirectX 11-capable video chipset yet and used a handful of in-house demos as well as Call of Duty: Black Ops. The synthetic tests showed an extreme level of detail, not only rendering detailed undersea creatures but a city with two billion total polygons, many of which can be seen at any one time.
Most of the performance improvements should come through boosting the number of processing cores from 448 to 512, to handle more tasks at once, as well as a significantly higher 192GB per second of memory bandwidth. The GTX 580 is expected to ship in late November or early December and would initially be focused on stand-alone upgrade cards, although computer vendors will likely start using them almost immediately.
