GeForce 810M vs GeForce 820M

Intro

The GeForce 810M makes use of a 28 nm design. nVidia has clocked the core speed at 738 MHz. The DDR3 RAM is set to run at a frequency of 900 MHz on this specific card. It features 48 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Compare all of that to the GeForce 820M, which comes with clock speeds of 719 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 96 SPUs along with 16 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce 820M should theoretically be a bit faster than the GeForce 810M overall. (explain)

GeForce 820M 16000 MB/sec
GeForce 810M 14400 MB/sec
Difference: 1600 (11%)

Texel Rate

The GeForce 820M will be a lot (approximately 95%) better at AF than the GeForce 810M. (explain)

GeForce 820M 11504 Mtexels/sec
GeForce 810M 5904 Mtexels/sec
Difference: 5600 (95%)

Pixel Rate

The GeForce 810M should be a bit (about 3%) better at FSAA than the GeForce 820M, and also able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 810M 2952 Mpixels/sec
GeForce 820M 2876 Mpixels/sec
Difference: 76 (3%)

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 maximum amount of information (measured in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics 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 colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
