GeForce GT 440 3GB vs Radeon R7 240

Intro

Compare those specifications to the Radeon R7 240, which comes with a core clock frequency of 730 MHz and a DDR3 memory speed of 900 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Radeon R7 240		28800 MB/sec
	Difference: 14400 (50%)

Texel Rate

The Radeon R7 240 is a bit (more or less 2%) better at AF than the GeForce GT 440 3GB. (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 344 (2%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 440 3GB is the winner, and very much so. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 8416 (144%)

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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
