GeForce GTX 260 vs GeForce GTX 560 Ti

Intro

Compare all of that to the GeForce GTX 560 Ti, which features 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 uses a 40 nm design. It is comprised of 384 SPUs, 64 Texture Address Units, and 32 ROPs.

GeForce GTX 260		111888 MB/sec
	Difference: 16368 (15%)

Texel Rate

The GeForce GTX 560 Ti is a lot (more or less 43%) better at texture filtering than the GeForce GTX 260. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 15744 (43%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 Ti is the winner, by a large margin. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GTX 260		16128 Mpixels/sec
	Difference: 10176 (63%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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