Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 2GB, in theory, should be quite a bit faster than the Radeon R9 M375X in general. (explain)

GeForce GTX 460 2GB 115200 MB/sec
Radeon R9 M375X 72000 MB/sec
Difference: 43200 (60%)

Texel Rate

The Radeon R9 M375X will be a small bit (more or less 7%) more effective at anisotropic filtering than the GeForce GTX 460 2GB. (explain)

Radeon R9 M375X 40600 Mtexels/sec
GeForce GTX 460 2GB 37800 Mtexels/sec
Difference: 2800 (7%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 460 2GB is the winner, and very much so. (explain)

GeForce GTX 460 2GB 21600 Mpixels/sec
Radeon R9 M375X 16240 Mpixels/sec
Difference: 5360 (33%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, 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 amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core 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 many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
