GeForce GT 440 1.5GB vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X, in theory, should perform much faster than the GeForce GT 440 1.5GB overall. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce GT 440 1.5GB		43200 MB/sec
	Difference: 28800 (67%)

Texel Rate

The Radeon R9 M375X will be a lot (about 185%) faster with regards to anisotropic filtering than the GeForce GT 440 1.5GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 26344 (185%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375X is a better choice, not by a very large margin though. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GT 440 1.5GB		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 data (counted in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
