GeForce GTX 550 Ti vs GeForce GTX 560

Intro

The GeForce GTX 550 Ti has a clock speed of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also uses a 192-bit memory bus, and uses a 40 nm design. It is comprised of 192 SPUs, 32 Texture Address Units, and 24 Raster Operation Units.

Compare all of that to the GeForce GTX 560, which features core clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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