GeForce 830M vs GeForce GTX 980 Ti

Intro

Compare all that to the GeForce GTX 980 Ti, which makes use of a 28 nm design. nVidia has clocked the core speed at 1000 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this card. It features 2816 SPUs along with 176 Texture Address Units and 96 ROPs.

GeForce 830M		25 Watts
GeForce GTX 980 Ti		250 Watts
	Difference: 225 Watts (900%)

Memory Bandwidth

The GeForce GTX 980 Ti should in theory perform quite a bit faster than the GeForce 830M in general. (explain)

GeForce GTX 980 Ti		336000 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 321600 (2233%)

Texel Rate

The GeForce GTX 980 Ti is quite a bit (more or less 969%) better at texture filtering than the GeForce 830M. (explain)

GeForce GTX 980 Ti		176000 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 159536 (969%)

Pixel Rate

The GeForce GTX 980 Ti will be much (about 1066%) more effective at AA than the GeForce 830M, and will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 980 Ti		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 maximum amount of information (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
