GeForce 8800 GT 256MB vs GeForce GTX 580
Intro
The GeForce 8800 GT 256MB has core speeds of 600 MHz on the GPU, and 700 MHz on the 256 MB of GDDR3 memory. It features 112 SPUs along with 56 Texture Address Units and 16 ROPs.Compare that to the GeForce GTX 580, which has GPU core speed of 772 MHz, and 1536 MB of GDDR5 RAM set to run at 1002 MHz through a 384-bit bus. It also features 512 SPUs, 64 Texture Address Units, and 48 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

Comments
One Response to “GeForce 8800 GT 256MB vs GeForce GTX 580”The information I got here for the Nvidia 8800GT vs the GTX 580 is great. I do still wish I could get an idea of the "relative compute performance" that is advertised on the Nvidia site. Or, even more meaningful to me would be something along the lines of a frame rate for transcoding.
