	Difference: 1600 (11%)

Texel Rate

The Radeon HD 4650 512MB is a lot (more or less 225%) more effective at texture filtering than the GeForce 810M. (explain)

Radeon HD 4650 512MB		19200 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 13296 (225%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 4650 512MB is superior to the GeForce 810M, and very much so. (explain)

Radeon HD 4650 512MB		4800 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 1848 (63%)

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 largest amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
