Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Geforce GTX 760, in theory, should perform a lot faster than the Radeon R9 M270X overall. (explain)

Geforce GTX 760		192256 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 120256 (167%)

Texel Rate

The Geforce GTX 760 will be much (about 224%) more effective at texture filtering than the Radeon R9 M270X. (explain)

Geforce GTX 760		94080 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 65080 (224%)

Pixel Rate

The Geforce GTX 760 will be quite a bit (more or less 170%) better at full screen anti-aliasing than the Radeon R9 M270X, and also able to handle higher screen resolutions without losing too much performance. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 19760 (170%)

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 largest amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It's 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
