GeForce GTX 880M vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which uses a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this card. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth

As far as performance goes, the GeForce GTX 880M should theoretically be just a bit superior to 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 much (approximately 100%) better at anisotropic filtering 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 high levels of AA is important to you, then the GeForce GTX 880M is a better choice, by far. (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 largest amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
