GeForce 830M vs GeForce GTX 1080

Intro

The GeForce 830M has a core clock speed of 1029 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It features 256 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare those specifications to the GeForce GTX 1080, which comes with a GPU core clock speed of 1607 MHz, and 8192 MB of GDDR5X RAM set to run at 1251 MHz through a 256-bit bus. It also is made up of 2560 Stream Processors, 160 TAUs, and 64 Raster Operation Units.

GeForce 830M 14400 MB/sec
Difference: 313280 (2176%)

Texel Rate

The GeForce GTX 1080 should be much (about 1462%) more effective at anisotropic filtering than the GeForce 830M. (explain)

GeForce GTX 1080 257120 Mtexels/sec
GeForce 830M 16464 Mtexels/sec
Difference: 240656 (1462%)

Pixel Rate

The GeForce GTX 1080 will be a lot (more or less 1149%) faster with regards to full screen anti-aliasing than the GeForce 830M, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 1080 102848 Mpixels/sec
GeForce 830M 8232 Mpixels/sec
Difference: 94616 (1149%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
