GeForce 810M vs Radeon HD 6850

Intro

Compare those specifications to the Radeon HD 6850, which has GPU core speed of 775 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also is made up of 960 SPUs, 48 Texture Address Units, and 32 ROPs.

GeForce 810M		15 Watts
Radeon HD 6850		127 Watts
	Difference: 112 Watts (747%)

Memory Bandwidth

The Radeon HD 6850 should theoretically perform quite a bit faster than the GeForce 810M overall. (explain)

Radeon HD 6850		128000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 113600 (789%)

Texel Rate

The Radeon HD 6850 is quite a bit (more or less 530%) more effective at AF than the GeForce 810M. (explain)

Radeon HD 6850		37200 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 31296 (530%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 6850 is superior to the GeForce 810M, by far. (explain)

Radeon HD 6850		24800 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 21848 (740%)

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 information (measured in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at 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 video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
