GeForce GT 440 1.5GB vs Radeon R9 M385X

Intro

Compare those specifications to the Radeon R9 M385X, which comes with a GPU core clock speed of 1100 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M385X should be much faster than the GeForce GT 440 1.5GB overall. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GT 440 1.5GB		43200 MB/sec
	Difference: 52800 (122%)

Texel Rate

The Radeon R9 M385X should be a lot (about 332%) better at texture filtering than the GeForce GT 440 1.5GB. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 47344 (332%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M385X is a better choice, and very much so. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GT 440 1.5GB		14256 Mpixels/sec
	Difference: 3344 (23%)

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 MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
