GeForce 830M vs GeForce GTX 560 Ti

Intro

Compare those specs to the GeForce GTX 560 Ti, which comes with clock speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

GeForce 830M		14400 MB/sec
	Difference: 113856 (791%)

Texel Rate

The GeForce GTX 560 Ti is quite a bit (about 220%) better at AF than the GeForce 830M. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 36144 (220%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 560 Ti is superior to the GeForce 830M, and very much so. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 18072 (220%)

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 (measured in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
