GeForce 810M		14400 MB/sec
	Difference: 11200 (78%)

Texel Rate

The GeForce 9500 GT 1GB GDDR3 will be quite a bit (approximately 49%) more effective at texture filtering than the GeForce 810M. (explain)

GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 2896 (49%)

Pixel Rate

The GeForce 9500 GT 1GB GDDR3 is a lot (more or less 49%) better at FSAA than the GeForce 810M, and will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 1448 (49%)

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 information (counted in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
