GeForce 820M vs GeForce 9600 GSO 384MB

Intro

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

Compare those specs to the GeForce 9600 GSO 384MB, which features core speeds of 550 MHz on the GPU, and 800 MHz on the 384 MB of GDDR3 RAM. It features 96 SPUs along with 48 Texture Address Units and 12 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
