Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 440 1.5GB		56 Watts
Radeon R9 M280X		75 Watts
	Difference: 19 Watts (34%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 M280X should perform quite a bit faster than the GeForce GT 440 1.5GB overall. (explain)

Radeon R9 M280X		88000 MB/sec
GeForce GT 440 1.5GB		43200 MB/sec
	Difference: 44800 (104%)

Texel Rate

The Radeon R9 M280X is much (approximately 254%) more effective at anisotropic filtering than the GeForce GT 440 1.5GB. (explain)

Radeon R9 M280X		50400 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 36144 (254%)

Pixel Rate

The Radeon R9 M280X will be just a bit (more or less 1%) more effective at full screen anti-aliasing than the GeForce GT 440 1.5GB, and also capable of handling higher resolutions without losing too much performance. (explain)

Radeon R9 M280X		14400 Mpixels/sec
GeForce GT 440 1.5GB		14256 Mpixels/sec
	Difference: 144 (1%)

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 max amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 ability to get to the max fill rate.
