GeForce 920M vs GeForce GTX 780 Ti

Intro

Compare all of that to the GeForce GTX 780 Ti, which has a GPU core clock speed of 875 MHz, and 3072 MB of GDDR5 RAM running at 1750 MHz through a 384-bit bus. It also features 2880 SPUs, 240 TAUs, and 48 Raster Operation Units.

The GeForce GTX 780 Ti will be quite a bit (more or less 588%) better at AF than the GeForce 920M. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 179472 (588%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 780 Ti is the winner, by far. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 34368 (450%)

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 largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. 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 maximum fill rate.
