GeForce 810M vs Radeon HD 6850

Intro

Compare all that to the Radeon HD 6850, which makes use of a 40 nm design. AMD has clocked the core speed at 775 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular model. It features 960 SPUs along with 48 TAUs and 32 Rasterization Operator Units.

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

Memory Bandwidth

Performance-wise, the Radeon HD 6850 should in theory be much better 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 anisotropic filtering than the GeForce 810M. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6850 is superior to the GeForce 810M, by a large margin. (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 max amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
