GeForce GTX 550 Ti vs GeForce GTX 560

Intro

The GeForce GTX 550 Ti has a GPU clock speed of 900 MHz, and the 1024 MB of GDDR5 RAM runs at 1026 MHz through a 192-bit bus. It also features 192 Stream Processors, 32 Texture Address Units, and 24 Raster Operation Units.

Compare all of that to the GeForce GTX 560, which has GPU clock speed of 810 MHz, and 1024 MB of GDDR5 memory set to run at 1001 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 TAUs, and 32 ROPs.

GeForce GTX 550 Ti 98496 MB/sec
Difference: 29632 (30%)

Texel Rate

The GeForce GTX 560 should be quite a bit (approximately 58%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 560 45360 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 16560 (58%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 560 is superior to the GeForce GTX 550 Ti, not by a very large margin though. (explain)

GeForce GTX 560 25920 Mpixels/sec
GeForce GTX 550 Ti 21600 Mpixels/sec
Difference: 4320 (20%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
