GeForce GTX 460 1GB vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which makes use of a 40 nm design. nVidia has clocked the core frequency at 810 MHz. The GDDR5 memory runs at a speed of 1001 MHz on this model. It features 336 SPUs as well as 56 TAUs and 32 ROPs.

GeForce GTX 460 1GB		115200 MB/sec
	Difference: 12928 (11%)

Texel Rate

The GeForce GTX 560 should be a small bit (approximately 20%) faster with regards to anisotropic filtering than the GeForce GTX 460 1GB. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 7560 (20%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 is superior to the GeForce GTX 460 1GB, though not by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GTX 460 1GB		21600 Mpixels/sec
	Difference: 4320 (20%)

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 megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 per second. This figure is calculated by multiplying the total number of texture units by the core 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
