Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375X will be 67% quicker than the GeForce GT 440 3GB in general, because of 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 should be a lot (about 185%) more effective at texture filtering 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

The Radeon R9 M375X should be a small bit (more or less 14%) more effective at full screen anti-aliasing than the GeForce GT 440 3GB, and will be capable of handling higher screen resolutions without slowing down too much. (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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
