GeForce 810M vs GeForce 830M

Intro

The GeForce 810M features clock speeds of 738 MHz on the GPU, and 900 MHz on the 1024 MB of DDR3 memory. It features 48 SPUs along with 8 TAUs and 4 ROPs.

Compare all of that to the GeForce 830M, which makes use of a 28 nm design. nVidia has set the core frequency at 1029 MHz. The DDR3 memory runs at a frequency of 900 MHz on this specific model. It features 256 SPUs along with 16 Texture Address Units and 8 ROPs.

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 exactly the same bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The GeForce 830M is much (about 179%) more effective at texture filtering than the GeForce 810M. (explain)

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

Pixel Rate

The GeForce 830M should be much (about 179%) more effective at AA than the GeForce 810M, and able to handle higher screen resolutions better. (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 largest amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 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 AA, 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 amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
