GeForce 810M vs GeForce 8400 GS 512MB

Intro

The GeForce 810M uses a 28 nm design. nVidia has clocked the core speed at 738 MHz. The DDR3 RAM runs at a frequency of 900 MHz on this specific card. It features 48 SPUs along with 8 TAUs and 4 ROPs.

Compare all that to the GeForce 8400 GS 512MB, which makes use of a 80 nm design. nVidia has clocked the core frequency at 650 MHz. The DDR2 RAM runs at a speed of 400 MHz on this specific card. It features 16 SPUs as well as 8 TAUs and 4 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of 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.
