GeForce 8800 GT 512MB vs GeForce GTX 560
Intro
The GeForce 8800 GT 512MB has a core clock speed of 600 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 256-bit bus, and makes use of a 65 nm design. It features 112 SPUs, 56 Texture Address Units, and 16 ROPs.Compare all of that to the GeForce GTX 560, which features clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
