GeForce GTX 880M 128000 MB/sec
GeForce GTX 460 (OEM) 108800 MB/sec
Difference: 19200 (18%)

Texel Rate

The GeForce GTX 880M will be a lot (more or less 235%) more effective at AF than the GeForce GTX 460 (OEM). (explain)

GeForce GTX 880M 122112 Mtexels/sec
GeForce GTX 460 (OEM) 36400 Mtexels/sec
Difference: 85712 (235%)

Pixel Rate

The GeForce GTX 880M should be much (approximately 47%) more effective at anti-aliasing than the GeForce GTX 460 (OEM), and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 880M 30528 Mpixels/sec
GeForce GTX 460 (OEM) 20800 Mpixels/sec
Difference: 9728 (47%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, 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 can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
