GeForce GTX 260 vs GeForce GTX 560 Ti

Intro

The GeForce GTX 260 has a GPU clock speed of 576 MHz, and the 896 MB of GDDR3 memory is set to run at 999 MHz through a 448-bit bus. It also features 192 SPUs, 64 TAUs, and 28 Raster Operation Units.

Compare those specs to the GeForce GTX 560 Ti, which features GPU clock speed of 822 MHz, and 1024 MB of GDDR5 memory running at 1002 MHz through a 256-bit bus. It also is made up of 384 SPUs, 64 TAUs, and 32 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
