GeForce 810M vs GeForce 8400 GS 512MB

Intro

The GeForce 810M has a GPU clock speed of 738 MHz, and the 1024 MB of DDR3 RAM runs at 900 MHz through a 64-bit bus. It also is made up of 48 Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.

Compare those specs to the GeForce 8400 GS 512MB, which makes use of a 80 nm design. nVidia has set the core speed at 650 MHz. The DDR2 RAM works at a speed of 400 MHz on this particular card. It features 16 SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record 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 clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
