GeForce 810M vs GeForce 830M

Intro

The GeForce 810M comes with a clock frequency of 738 MHz and a DDR3 memory frequency of 900 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It is made up of 48 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Compare those specs to the GeForce 830M, which comes with core speeds of 1029 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. 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 memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The GeForce 830M is quite a bit (approximately 179%) more effective at anisotropic filtering than the GeForce 810M. (explain)

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

Pixel Rate

If using a high screen resolution 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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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