GeForce GTX 460 2GB vs GeForce GTX 560 Ti 448

Intro

Compare all that to the GeForce GTX 560 Ti 448, which features a core clock speed of 732 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 320-bit bus, and makes use of a 40 nm design. It is made up of 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 Ti 448 is superior to the GeForce GTX 460 2GB, and very much so. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 7680 (36%)

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 (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the 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 most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
