GeForce 830M vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which has GPU clock speed of 810 MHz, and 1024 MB of GDDR5 memory set to run at 1001 MHz through a 256-bit bus. It also features 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

GeForce 830M		14400 MB/sec
	Difference: 113728 (790%)

Texel Rate

The GeForce GTX 560 will be a lot (about 176%) faster with regards to texture filtering than the GeForce 830M. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 28896 (176%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 560 is the winner, by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 17688 (215%)

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 max amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
