GeForce GTX 460 SE 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 clocked the core frequency at 822 MHz. The GDDR5 memory runs at a speed of 1002 MHz on this particular card. It features 384 SPUs along with 64 TAUs and 32 ROPs.

GeForce GTX 460 SE		108800 MB/sec
	Difference: 19456 (18%)

Texel Rate

The GeForce GTX 560 Ti will be much (about 69%) better at texture filtering than the GeForce GTX 460 SE. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 21408 (69%)

Pixel Rate

The GeForce GTX 560 Ti should be a lot (about 26%) more effective at AA than the GeForce GTX 460 SE, and also will be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 5504 (26%)

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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total 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 applied per second.

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