GeForce 810M vs Radeon HD 4770

Intro

Compare that to the Radeon HD 4770, which features GPU core speed of 750 MHz, and 512 MB of GDDR5 memory set to run at 800 MHz through a 128-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

GeForce 810M		15 Watts
Radeon HD 4770		80 Watts
	Difference: 65 Watts (433%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 4770 should be much faster than the GeForce 810M overall. (explain)

Radeon HD 4770		51200 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 36800 (256%)

Texel Rate

The Radeon HD 4770 is quite a bit (approximately 307%) better at anisotropic filtering than the GeForce 810M. (explain)

Radeon HD 4770		24000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 18096 (307%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 4770 is superior to the GeForce 810M, by a large margin. (explain)

Radeon HD 4770		12000 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 9048 (307%)

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 megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better 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 number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
