Nvidia Announced 55nm, Dual-GPU GeForce GTX 295 Graphics Card
Nvidia finally announced the h
The graphics card is based on two shrinked vesions of the company's GT200 GPUs (GT200b), manufactured using the 55nm process, matching the AMD's Radeon HD 4000-series GPUs.
The GTX 295's GPUs will run at a core clock of 576MHz, with shaders clocked at 1242MHz. Like today's GeForce GTX 260, each GPU will have seven active ROP partitions and a 448-bit path to 896MB of memory. That memory will be of the GDDR3 variety, running at 1000MHz (or 2000 MT/s). Unlike the GTX 260, though, the GTX 295's individual GPUs will have all ten of their thread processor clusters intact, for a total of 240 stream processors per chip.
The GeForce GTX 295 will consume 289W of electric power (six and eight pin PSU required) and it will be equipped with two DVI-I and one HDMI ports. It will also support dual-card configurations, for quad SLI, or one of its GPUs can be reassigned to handle PhysX calculations rather than graphics.
According to the specifications of the card, it should be highly competitive to Radeon HD 4870 X2 dual-GPU proposal, at least in terms of memory bandwidth and texture filtering capacities. But still, we have to wait until we actually have the card in our hands and run some benchmarks. The GeForce GTX 295 will debuts at the CES show in Las Vegas in January, and Nvidia seems to rush into the announcement of the card in an effort to slow AMD's momentum during the holiday season.
