GeForce GTX 260 vs GeForce GTX 570

Intro

The GeForce GTX 260 has a GPU core speed of 576 MHz, and the 896 MB of GDDR3 RAM runs at 999 MHz through a 448-bit bus. It also is made up of 192 SPUs, 64 TAUs, and 28 ROPs.

Compare that to the GeForce GTX 570, which has a clock frequency of 732 MHz and a GDDR5 memory speed of 950 MHz. It also features a 320-bit bus, and makes use of a 40 nm design. It features 480 SPUs, 60 Texture Address Units, and 40 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
