GeForce GT 440 3GB vs Radeon R7 M260

Intro

Compare those specs to the Radeon R7 M260, which makes use of a 28 nm design. AMD has set the core frequency at 715 MHz. The DDR3 memory runs at a frequency of 1000 MHz on this particular model. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 2904 (20%)

Pixel Rate

The GeForce GT 440 3GB should be much (about 149%) more effective at AA than the Radeon R7 M260, and also able to handle higher resolutions without losing too much performance. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 8536 (149%)

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 megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
