GeForce GTX 870M vs Radeon RX 460 2GB

Intro

Compare all that to the Radeon RX 460 2GB, which has a GPU core clock speed of 1090 MHz, and 2048 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 ROPs.

GeForce GTX 870M		96000 MB/sec
	Difference: 16000 (17%)

Texel Rate

The GeForce GTX 870M should be a lot (approximately 73%) more effective at anisotropic filtering than the Radeon RX 460 2GB. (explain)

GeForce GTX 870M		105392 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 44352 (73%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 870M is the winner, by a large margin. (explain)

GeForce GTX 870M		22584 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 5144 (29%)

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 maximum amount of data (in units of MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
