Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M365X should be quite a bit faster than the GeForce GT 440 1.5GB overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce GT 440 1.5GB		43200 MB/sec
	Difference: 28800 (67%)

Texel Rate

The Radeon R9 M365X is much (more or less 160%) better at AF than the GeForce GT 440 1.5GB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 22744 (160%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M365X is superior to the GeForce GT 440 1.5GB, but only just. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce GT 440 1.5GB		14256 Mpixels/sec
	Difference: 544 (4%)

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 information (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
