GeForce GTX 550 Ti vs GeForce GTX 560 Ti
Intro
The GeForce GTX 550 Ti uses a 40 nm design. nVidia has clocked the core frequency at 900 MHz. The GDDR5 RAM works at a speed of 1026 MHz on this specific model. It features 192 SPUs as well as 32 TAUs and 24 ROPs.Compare all that to the GeForce GTX 560 Ti, which has a clock speed of 822 MHz and a GDDR5 memory speed of 1002 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is made up of 384 SPUs, 64 TAUs, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
