GeForce GTX 970M vs Radeon RX 460 2GB

Intro

Compare all that to the Radeon RX 460 2GB, which has core speeds of 1090 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 2GB is 17% quicker than the GeForce GTX 970M in general, because of its greater data rate. (explain)

Radeon RX 460 2GB		112000 MB/sec
GeForce GTX 970M		96000 MB/sec
	Difference: 16000 (17%)

Texel Rate

The GeForce GTX 970M is a lot (more or less 21%) better at anisotropic filtering than the Radeon RX 460 2GB. (explain)

GeForce GTX 970M		73920 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 12880 (21%)

Pixel Rate

The GeForce GTX 970M is a lot (approximately 154%) more effective at anti-aliasing than the Radeon RX 460 2GB, and also will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 970M		44352 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 26912 (154%)

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 information (in units of megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video 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 card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
