Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M370X will be 67% quicker than the GeForce GT 440 3GB overall, because of its higher data rate. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 28800 (67%)

Texel Rate

The Radeon R9 M370X is much (approximately 124%) faster with regards to AF than the GeForce GT 440 3GB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 17744 (124%)

Pixel Rate

The GeForce GT 440 3GB will be a little bit (more or less 11%) better at AA than the Radeon R9 M370X, and able to handle higher resolutions without slowing down too much. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 1456 (11%)

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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video 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 maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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 bandwidth is, the lower the potential to get to the max fill rate.
