Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 370 4G		110 Watts
Geforce GTX 690		300 Watts
	Difference: 190 Watts (173%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 690 will be 115% faster than the Radeon R7 370 4G in general, due to its higher data rate. (explain)

Geforce GTX 690		384512 MB/sec
Radeon R7 370 4G		179200 MB/sec
	Difference: 205312 (115%)

Texel Rate

The Geforce GTX 690 is quite a bit (more or less 275%) better at AF than the Radeon R7 370 4G. (explain)

Geforce GTX 690		234240 Mtexels/sec
Radeon R7 370 4G		62400 Mtexels/sec
	Difference: 171840 (275%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Geforce GTX 690 is the winner, by far. (explain)

Geforce GTX 690		58560 Mpixels/sec
Radeon R7 370 4G		31200 Mpixels/sec
	Difference: 27360 (88%)

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 largest amount of information (counted in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video 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 Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
