Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M365X should perform 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 should be a lot (approximately 160%) more effective at texture filtering 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

The Radeon R9 M365X will be a little bit (more or less 4%) better at FSAA than the GeForce GT 440 1.5GB, and also will be able to handle higher resolutions better. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
