GeForce 810M vs Radeon R7 240

Intro

Compare all of that to the Radeon R7 240, which comes with core speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.

The Radeon R7 240 is much (about 147%) faster with regards to AF than the GeForce 810M. (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 8696 (147%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 240 is the winner, and very much so. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 2888 (98%)

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 data (in units of MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
