GeForce 8800 GT 256MB vs GeForce GTX 580
Intro
The GeForce 8800 GT 256MB features core speeds of 600 MHz on the GPU, and 700 MHz on the 256 MB of GDDR3 RAM. It features 112 SPUs along with 56 TAUs and 16 Rasterization Operator Units.Compare those specs to the GeForce GTX 580, which comes with 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 is made up of 512 Stream Processors, 64 Texture Address Units, and 48 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max 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.
