Today, NVIDIA officially announced it's new GeForce GTX 200 series of GPUs, and the first two products in the family, the GeForce GTX 280 and the GeForce GTX 260.Nvidia claims the GeForce GTX 200 processors provide up to 50 percent faster gaming performance over the GeForce 8800 Ultra GPU, which is even faster than the top-end Nvidia graphics card available as an add-on board for today’s Mac Pro systems. The GPUs also support Scalable Link Interface (SLI), a technology that enables more than one Nvidia card to work together in the same computer in parallel; PureVideo HD, video decoding and post-processing technology; and Compute Unified Device Architecture (CUDA), which enables programmers to offload processor-intensive tasks to the Nvidia graphics chip and card.
The new chip has 1.4 billion transistors, yes that billion with a "B", about 80% of which are used to perform the mathematical calculations required for 3D rendering. (By comparison, only a small fraction of the 820 million transistors in a quad-core Intel processor are directly used to execute software; the rest comprise memory blocks, instruction decoders, data transfer channels, and other support functions.)
That's almost twice as many transistors as found on NVIDIA's 9800 series chips. The extra transistors boost the number of cores per chip from 128 to 240. Each core runs at almost 1.3 GHz.
Pricing for the cards is set at $399 for the GeForce GTX 260 and $649 for the GeForce GTX 280.
