GeForce GTX 970M vs Radeon RX 460

Intro

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

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Radeon RX 460 should in theory be just a bit superior to the GeForce GTX 970M overall. (explain)

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

Texel Rate

The GeForce GTX 970M should be quite a bit (about 21%) more effective at texture filtering than the Radeon RX 460. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 970M is the winner, and very much so. (explain)

GeForce GTX 970M		44352 Mpixels/sec
Radeon RX 460		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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
