Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 285 1GB will be 121% quicker than the Radeon R9 M365X in general, because of its greater data rate. (explain)

GeForce GTX 285 1GB		158976 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 86976 (121%)

Texel Rate

The GeForce GTX 285 1GB should be quite a bit (about 40%) faster with regards to anisotropic filtering than the Radeon R9 M365X. (explain)

GeForce GTX 285 1GB		51840 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 14840 (40%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 285 1GB is a better choice, by a large margin. (explain)

GeForce GTX 285 1GB		20736 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 5936 (40%)

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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
