GeForce GT 440 3GB vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which features a GPU core clock speed of 1015 MHz, and 4096 MB of DDR3 memory set to run at 1100 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 440 3GB, in theory, should perform a lot faster than the Radeon R9 M375 in general. (explain)

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

Texel Rate

The Radeon R9 M375 will be much (more or less 185%) faster with regards to 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 running with high levels of AA is important to you, then the Radeon R9 M375 is a better choice, but it probably won't make a huge difference. (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 max amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many 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.
