GeForce GT 440 3GB vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which features a GPU core clock speed of 1100 MHz, and 4096 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X is 122% quicker than the GeForce GT 440 3GB overall, due to its greater data rate. (explain)

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

Texel Rate

The Radeon R9 M385X will be quite a bit (about 332%) more effective at anisotropic filtering 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

The Radeon R9 M385X should be much (approximately 23%) better at anti-aliasing than the GeForce GT 440 3GB, and will be able to handle higher resolutions without slowing down too much. (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 max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units 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 applied per second.

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