Memory Bandwidth

As far as performance goes, the GeForce GTX 880M should in theory be just a bit better than the Radeon RX 460 2GB overall. (explain)

GeForce GTX 880M		128000 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 16000 (14%)

Texel Rate

The GeForce GTX 880M is a lot (about 100%) more effective at AF than the Radeon RX 460 2GB. (explain)

GeForce GTX 880M		122112 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 61072 (100%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 880M is a better choice, by a large margin. (explain)

GeForce GTX 880M		30528 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 13088 (75%)

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 transferred past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can 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 clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
