GeForce GT 440 3GB vs Radeon R7 M265

Intro

Compare all of that to the Radeon R7 M265, which makes use of a 28 nm design. AMD has set the core speed at 725 MHz. The DDR3 RAM is set to run at a speed of 1000 MHz on this specific card. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 440 3GB should theoretically perform quite a bit faster than the Radeon R7 M265 in general. (explain)

GeForce GT 440 3GB		43200 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 11200 (35%)

Texel Rate

The Radeon R7 M265 should be a lot (more or less 22%) better at texture filtering than the GeForce GT 440 3GB. (explain)

Radeon R7 M265		17400 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 3144 (22%)

Pixel Rate

The GeForce GT 440 3GB is much (about 146%) faster with regards to anti-aliasing than the Radeon R7 M265, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 8456 (146%)

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 (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

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