GeForce 810M vs GeForce GT 240 GDDR5

Intro

Compare that to the GeForce GT 240 GDDR5, which uses a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 memory works at a frequency of 850 MHz on this specific card. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GT 240 GDDR5 is 278% faster than the GeForce 810M in general, because of its higher 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 (more or less 198%) more effective at texture filtering than the GeForce 810M. (explain)

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

Pixel Rate

The GeForce GT 240 GDDR5 is a lot (about 49%) more effective at FSAA than the GeForce 810M, and should be capable of handling higher resolutions better. (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 transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
