GeForce 820M vs GeForce 9600 GSO ASUS 512

Intro

The GeForce 820M comes with a GPU core clock speed of 719 MHz, and the 2048 MB of DDR3 RAM runs at 1000 MHz through a 64-bit bus. It also features 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Compare all that to the GeForce 9600 GSO ASUS 512, which features a core clock speed of 550 MHz and a DDR2 memory speed of 500 MHz. It also uses a 128-bit bus, and makes use of a 65 nm design. It is made up of 96 SPUs, 48 Texture Address Units, 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 in theory they should perform the same. (explain)

Texel Rate

The GeForce 9600 GSO ASUS 512 will be much (approximately 129%) better 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 should be a lot (approximately 129%) better at anti-aliasing than the GeForce 820M, and also will be capable of handling higher screen resolutions while still performing well. (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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
