GeForce 820M vs GeForce 9600 GSO ASUS 512

Intro

The GeForce 820M uses a 28 nm design. nVidia has set the core frequency at 719 MHz. The DDR3 memory runs at a frequency of 1000 MHz on this particular card. It features 96 SPUs along with 16 TAUs and 4 Rasterization Operator Units.

Compare all of that to the GeForce 9600 GSO ASUS 512, which uses a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The DDR2 RAM is set to run at a speed of 500 MHz on this particular model. It features 96 SPUs as well as 48 TAUs and 12 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 820M 15 Watts
GeForce 9600 GSO ASUS 512 84 Watts
Difference: 69 Watts (460%)

Memory Bandwidth

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

Texel Rate

The GeForce 9600 GSO ASUS 512 will be quite a bit (approximately 129%) more effective at anisotropic filtering than the GeForce 820M. (explain)

GeForce 9600 GSO ASUS 512 26400 Mtexels/sec
GeForce 820M 11504 Mtexels/sec
Difference: 14896 (129%)

Pixel Rate

The GeForce 9600 GSO ASUS 512 will be quite a bit (about 129%) more effective at FSAA than the GeForce 820M, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce 9600 GSO ASUS 512 6600 Mpixels/sec
GeForce 820M 2876 Mpixels/sec
Difference: 3724 (129%)

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 data (in units of megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, 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 worked out by multiplying the total amount of texture units of the card 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
