GeForce GT 440 3GB vs Radeon R9 M365X

Intro

Compare those specifications to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M365X should perform quite a bit faster than the GeForce GT 440 3GB overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 28800 (67%)

Texel Rate

The Radeon R9 M365X is much (more or less 160%) more effective at AF than the GeForce GT 440 3GB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 22744 (160%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M365X is the winner, though not by far. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce GT 440 3GB		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 data (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
