GeForce GT 440 3GB vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which comes with a GPU core clock speed of 1100 MHz, and 4096 MB of GDDR5 memory set to run at 1500 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M385X should be much faster than the GeForce GT 440 3GB in general. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 52800 (122%)

Texel Rate

The Radeon R9 M385X should be a lot (about 332%) more effective at AF than the GeForce GT 440 3GB. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 47344 (332%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M385X is superior to the GeForce GT 440 3GB, and very much so. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GT 440 3GB		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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses 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 can be applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
