GeForce 810M vs GeForce 830M

Intro

The GeForce 810M has a GPU core speed of 738 MHz, and the 1024 MB of DDR3 RAM is set to run at 900 MHz through a 64-bit bus. It also is comprised of 48 SPUs, 8 TAUs, and 4 Raster Operation Units.

Compare those specs to the GeForce 830M, which features a clock speed of 1029 MHz and a DDR3 memory speed of 900 MHz. It also features a 64-bit memory bus, and makes use of a 28 nm design. It features 256 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M 15 Watts
GeForce 830M 25 Watts
Difference: 10 Watts (67%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce 830M should be much (about 179%) better at texture filtering than the GeForce 810M. (explain)

GeForce 830M 16464 Mtexels/sec
GeForce 810M 5904 Mtexels/sec
Difference: 10560 (179%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 830M is a better choice, and very much so. (explain)

GeForce 830M 8232 Mpixels/sec
GeForce 810M 2952 Mpixels/sec
Difference: 5280 (179%)

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 information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 processed per second. This number is calculated by multiplying the total number of texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
