GeForce 810M vs GeForce 820M

Intro

The GeForce 810M uses a 28 nm design. nVidia has set the core speed at 738 MHz. The DDR3 memory runs at a speed of 900 MHz on this card. It features 48 SPUs along with 8 Texture Address Units and 4 ROPs.

Compare all that to the GeForce 820M, which uses a 28 nm design. nVidia has clocked the core frequency at 719 MHz. The DDR3 memory runs at a frequency of 1000 MHz on this model. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the GeForce 820M should in theory be a small bit superior to the GeForce 810M in general. (explain)

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

Texel Rate

The GeForce 820M is quite a bit (about 95%) more effective at texture filtering than the GeForce 810M. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce 810M is superior to the GeForce 820M, though only just barely. (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 largest amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
