Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 440 1.5GB is 23% quicker than the Radeon R9 M375 in general, because of its higher bandwidth. (explain)

GeForce GT 440 1.5GB		43200 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 8000 (23%)

Texel Rate

The Radeon R9 M375 will be a lot (more or less 185%) more effective at anisotropic filtering than the GeForce GT 440 1.5GB. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 26344 (185%)

Pixel Rate

The Radeon R9 M375 will be a bit (more or less 14%) more effective at FSAA than the GeForce GT 440 1.5GB, and will be able to handle higher resolutions better. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GT 440 1.5GB		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 (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
