GeForce 810M		14400 MB/sec
Radeon HD 4550 256MB		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 810M will be a lot (more or less 23%) more effective at AF than the Radeon HD 4550 256MB. (explain)

GeForce 810M		5904 Mtexels/sec
Radeon HD 4550 256MB		4800 Mtexels/sec
	Difference: 1104 (23%)

Pixel Rate

The GeForce 810M should be much (approximately 23%) faster with regards to anti-aliasing than the Radeon HD 4550 256MB, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce 810M		2952 Mpixels/sec
Radeon HD 4550 256MB		2400 Mpixels/sec
	Difference: 552 (23%)

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 (counted in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
