Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE should be 51% faster than the Radeon R9 M365X overall, because of its greater data rate. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 36800 (51%)

Texel Rate

The Radeon R9 M365X will be a little bit (more or less 19%) more effective at AF than the GeForce GTX 460 SE. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 5800 (19%)

Pixel Rate

The GeForce GTX 460 SE should be a lot (more or less 41%) better at full screen anti-aliasing than the Radeon R9 M365X, and also will be capable of handling higher resolutions better. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 6000 (41%)

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 MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, 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 amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
