GeForce GT 440 3GB vs Radeon R7 M265

Intro

Compare all that to the Radeon R7 M265, which uses a 28 nm design. AMD has set the core speed at 725 MHz. The DDR3 RAM runs at a frequency of 1000 MHz on this specific model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 440 3GB is 35% faster than the Radeon R7 M265 overall, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon R7 M265 will be much (about 22%) better at AF 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

If running with a high resolution is important to you, then the GeForce GT 440 3GB is superior to the Radeon R7 M265, and very much so. (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 max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
