Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375X should be 67% quicker than the GeForce GT 440 3GB overall, due to its higher bandwidth. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 28800 (67%)

Texel Rate

The Radeon R9 M375X will be quite a bit (approximately 185%) faster with regards to AF than the GeForce GT 440 3GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 26344 (185%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375X is superior to the GeForce GT 440 3GB, not by a very large margin though. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 1984 (14%)

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 largest amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
