Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 (OEM) should in theory perform a lot faster than the Radeon R9 M265X in general. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 36800 (51%)

Texel Rate

The GeForce GTX 460 (OEM) is much (more or less 58%) better at texture filtering than the Radeon R9 M265X. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 13400 (58%)

Pixel Rate

The GeForce GTX 460 (OEM) is quite a bit (about 126%) better at anti-aliasing than the Radeon R9 M265X, and also capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 11600 (126%)

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 largest amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics 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 number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
