Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 965M		60 Watts
Radeon R7 370 4G		110 Watts
	Difference: 50 Watts (83%)

Memory Bandwidth

As far as performance goes, the Radeon R7 370 4G should theoretically be a lot superior to the GeForce GTX 965M overall. (explain)

Radeon R7 370 4G		179200 MB/sec
GeForce GTX 965M		64000 MB/sec
	Difference: 115200 (180%)

Texel Rate

The Radeon R7 370 4G is a small bit (more or less 3%) more effective at anisotropic filtering than the GeForce GTX 965M. (explain)

Radeon R7 370 4G		62400 Mtexels/sec
GeForce GTX 965M		60416 Mtexels/sec
	Difference: 1984 (3%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 370 4G is the winner, but it probably won't make a huge difference. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
GeForce GTX 965M		30208 Mpixels/sec
	Difference: 992 (3%)

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 information (measured in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 are processed per second. This 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
