GeForce GTX 550 Ti vs GeForce GTX 560 Ti
Intro
The GeForce GTX 550 Ti comes with clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs as well as 32 TAUs and 24 ROPs.Compare those specifications to the GeForce GTX 560 Ti, which comes with a clock speed of 822 MHz and a GDDR5 memory speed of 1002 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 384 SPUs, 64 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the potential to reach the max fill rate.
