GeForce 830M vs GeForce GTX 980M

Intro

The GeForce 830M comes with a GPU clock speed of 1029 MHz, and the 2048 MB of DDR3 memory runs at 900 MHz through a 64-bit bus. It also is comprised of 256 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare those specifications to the GeForce GTX 980M, which features core clock speeds of 1038 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 memory. It features 1536 SPUs along with 96 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M 25 Watts
GeForce GTX 980M 100 Watts
Difference: 75 Watts (300%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 980M should be 789% faster than the GeForce 830M in general, due to its higher data rate. (explain)

GeForce GTX 980M 128000 MB/sec
GeForce 830M 14400 MB/sec
Difference: 113600 (789%)

Texel Rate

The GeForce GTX 980M will be quite a bit (about 505%) faster with regards to anisotropic filtering than the GeForce 830M. (explain)

GeForce GTX 980M 99648 Mtexels/sec
GeForce 830M 16464 Mtexels/sec
Difference: 83184 (505%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 980M is superior to the GeForce 830M, and very much so. (explain)

GeForce GTX 980M 66432 Mpixels/sec
GeForce 830M 8232 Mpixels/sec
Difference: 58200 (707%)

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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number 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 filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
