GeForce GTX 460 2GB vs GeForce GTX 560 Ti

Intro

Compare those specifications to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has set the core frequency at 822 MHz. The GDDR5 memory is set to run at a frequency of 1002 MHz on this model. It features 384 SPUs as well as 64 Texture Address Units and 32 ROPs.

GeForce GTX 460 2GB		115200 MB/sec
	Difference: 13056 (11%)

Texel Rate

The GeForce GTX 560 Ti will be much (about 39%) more effective at texture filtering than the GeForce GTX 460 2GB. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 14808 (39%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti is a better choice, by a large margin. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 4704 (22%)

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 data (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
