GeForce GT 440 3GB vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which comes with core speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 440 3GB is 23% quicker than the Radeon R9 M375 in general, due to its greater data rate. (explain)

GeForce GT 440 3GB		43200 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 8000 (23%)

Texel Rate

The Radeon R9 M375 should be much (approximately 185%) better at anisotropic filtering than the GeForce GT 440 3GB. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 26344 (185%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M375 is the winner, but only just. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 1984 (14%)

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 maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
