GeForce 810M vs GeForce GT 240 GDDR5

Intro

Compare those specs to the GeForce GT 240 GDDR5, which has a core clock frequency of 550 MHz and a GDDR5 memory speed of 850 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It is made up of 96 SPUs, 32 Texture Address Units, and 8 ROPs.

GeForce 810M		15 Watts
GeForce GT 240 GDDR5		70 Watts
	Difference: 55 Watts (367%)

Memory Bandwidth

In theory, the GeForce GT 240 GDDR5 should be 278% faster than the GeForce 810M in general, because of its greater bandwidth. (explain)

GeForce GT 240 GDDR5		54400 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 40000 (278%)

Texel Rate

The GeForce GT 240 GDDR5 is a lot (approximately 198%) faster with regards to texture filtering than the GeForce 810M. (explain)

GeForce GT 240 GDDR5		17600 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 11696 (198%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 240 GDDR5 is the winner, by a large margin. (explain)

GeForce GT 240 GDDR5		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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If 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 processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
