Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 590 should be 356% quicker than the Radeon R9 M365X overall, because of its greater data rate. (explain)

GeForce GTX 590		328320 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 256320 (356%)

Texel Rate

The GeForce GTX 590 should be quite a bit (about 110%) better at anisotropic filtering than the Radeon R9 M365X. (explain)

GeForce GTX 590		77696 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 40696 (110%)

Pixel Rate

The GeForce GTX 590 should be quite a bit (about 294%) better at FSAA than the Radeon R9 M365X, and also able to handle higher resolutions while still performing well. (explain)

GeForce GTX 590		58272 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 43472 (294%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
