GeForce 810M vs Radeon R9 M280X

Intro

Compare that to the Radeon R9 M280X, which features core clock speeds of 900 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

GeForce 810M		15 Watts
Radeon R9 M280X		75 Watts
	Difference: 60 Watts (400%)

Memory Bandwidth

The Radeon R9 M280X should theoretically perform quite a bit faster than the GeForce 810M overall. (explain)

Radeon R9 M280X		88000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 73600 (511%)

Texel Rate

The Radeon R9 M280X should be quite a bit (about 754%) more effective at anisotropic filtering than the GeForce 810M. (explain)

Radeon R9 M280X		50400 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 44496 (754%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M280X is superior to the GeForce 810M, and very much so. (explain)

Radeon R9 M280X		14400 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 11448 (388%)

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 (measured in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
