Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 will be 20% faster than the Radeon R9 M365X overall, because of its higher bandwidth. (explain)

GeForce GTX 460		86400 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 460 should be a small bit (about 2%) more effective at AF than the Radeon R9 M365X. (explain)

GeForce GTX 460		37800 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 800 (2%)

Pixel Rate

The GeForce GTX 460 will be just a bit (approximately 9%) more effective at anti-aliasing than the Radeon R9 M365X, and will be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 1400 (9%)

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 information (measured in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount 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 calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
