The GeForce 256 is the original release in Nvidia's "GeForce" product line.Announced on August 31, 1999 and released on October 11, 1999, the GeForce 256 improves on its predecessor by increasing the number of fixed pixel pipelines, offloading host geometry calculations to a hardware transform and lighting (T&L) engine, and adding hardware motion compensation for MPEG-2 video.
G400MAX had the highest memory bandwidth of any card before the release of the DDR-equipped version of NVIDIA GeForce 256. Perhaps the most notable feature of G400 is its ability to drive two separate monitors to display a single desktop. This feature is known as "DualHead" and was a decisive edge for Matrox over the card's competitors at the time.
This 8800 GTS has 128 stream processors, compared to the 96 processors of the original GTS models. It is equipped with 512 MB GDDR3 on a 256-bit bus. Combined with a 650 MHz core clock and architectural enhancements, this gives the card raw GPU performance exceeding that of 8800 GTX, but it is constrained by the narrower 256-bit memory bus.
The 9800GX2 utilizes two separate 256-bit memory busses, one for each GPU and its respective 512 MB of memory, which equates to an overall of 1 GB of memory on the card (although the SLI configuration of the chips necessitates mirroring the frame buffer between the two chips, thus effectively halving the memory performance of a 256-bit/512 MB ...
Core config – The layout of the graphics pipeline, in terms of functional units. Over time the number, type, and variety of functional units in the GPU core has changed significantly; before each section in the list there is an explanation as to what functional units are present in each generation of processors.
The Parhelia-512 was the first GPU by Matrox to be equipped with a 256-bit memory bus, giving it an advantage over other cards of the time in the area of memory bandwidth. The "-512" suffix refers to the 512-bit ring bus. The Parhelia processor featured Glyph acceleration, where anti-aliasing of text was accelerated by the hardware.
