GeForce 810M vs Radeon R5 M255

Intro

Compare those specs to the Radeon R5 M255, which comes with core clock speeds of 940 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R5 M255 will be 11% faster than the GeForce 810M overall, due to its higher bandwidth. (explain)

Radeon R5 M255		16000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The Radeon R5 M255 should be a lot (more or less 218%) better at texture filtering than the GeForce 810M. (explain)

Radeon R5 M255		18800 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 12896 (218%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R5 M255 is the winner, by far. (explain)

Radeon R5 M255		7520 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 4568 (155%)

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 max amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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