GeForce 810M vs GeForce GT 240 GDDR5 1GB

Intro

Compare those specifications to the GeForce GT 240 GDDR5 1GB, which makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 memory runs at a speed of 850 MHz on this card. It features 96 SPUs along with 32 TAUs and 8 ROPs.

Texel Rate

The GeForce GT 240 GDDR5 1GB is a lot (more or less 198%) faster with regards to anisotropic filtering than the GeForce 810M. (explain)

GeForce GT 240 GDDR5 1GB		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 1GB is superior to the GeForce 810M, by far. (explain)

GeForce GT 240 GDDR5 1GB		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 (measured in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has 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 amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
