GeForce 820M vs GeForce 9600 GSO 384MB

Intro

The GeForce 820M makes use of a 28 nm design. nVidia has clocked the core frequency at 719 MHz. The DDR3 memory is set to run at a speed of 1000 MHz on this particular card. It features 96 SPUs as well as 16 TAUs and 4 Rasterization Operator Units.

Compare those specifications to the GeForce 9600 GSO 384MB, which uses a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR3 RAM works at a frequency of 800 MHz on this particular model. It features 96 SPUs as well as 48 TAUs and 12 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, 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 card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
