Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 440 3GB is 23% faster than the Radeon R9 M375 in general, due to its higher bandwidth. (explain)

GeForce GT 440 3GB		43200 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 8000 (23%)

Texel Rate

The Radeon R9 M375 is a lot (approximately 185%) more effective at AF than the GeForce GT 440 3GB. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 26344 (185%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M375 is the winner, but it probably won't make a huge difference. (explain)

Radeon R9 M375		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 maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
