GeForce 830M vs GeForce GTX 980 Ti

Intro

Compare all of that to the GeForce GTX 980 Ti, which has clock speeds of 1000 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR5 memory. It features 2816 SPUs along with 176 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 980 Ti will be 2233% quicker than the GeForce 830M in general, due to its higher data rate. (explain)

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

Texel Rate

The GeForce GTX 980 Ti will be much (more or less 969%) more effective at AF than the GeForce 830M. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 980 Ti is the winner, and very much so. (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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core clock 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 processed in a second.

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