Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M395X		125 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 25 Watts (20%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 M395X should be much faster than the GeForce GTX 460 SE in general. (explain)

Radeon R9 M395X		160000 MB/sec
GeForce GTX 460 SE		108800 MB/sec
	Difference: 51200 (47%)

Texel Rate

The Radeon R9 M395X will be quite a bit (about 197%) more effective at anisotropic filtering than the GeForce GTX 460 SE. (explain)

Radeon R9 M395X		92544 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 61344 (197%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M395X is superior to the GeForce GTX 460 SE, not by a very large margin though. (explain)

Radeon R9 M395X		23136 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 2336 (11%)

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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
