GeForce 830M vs GeForce GTX Titan X

Intro

Compare those specs to the GeForce GTX Titan X, which comes with a GPU core clock speed of 1000 MHz, and 12288 MB of GDDR5 memory running at 1750 MHz through a 384-bit bus. It also features 3072 SPUs, 192 TAUs, and 96 Raster Operation Units.

GeForce 830M		16464 Mtexels/sec
	Difference: 175536 (1066%)

Pixel Rate

The GeForce GTX Titan X should be much (more or less 1066%) better at AA than the GeForce 830M, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 87768 (1066%)

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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
