GeForce 810M vs GeForce 8500 GT

Intro

The GeForce 810M comes with a core clock frequency of 738 MHz and a DDR3 memory speed of 900 MHz. It also features a 64-bit memory bus, and makes use of a 28 nm design. It is made up of 48 SPUs, 8 TAUs, and 4 ROPs.

Compare all that to the GeForce 8500 GT, which has GPU core speed of 450 MHz, and 512 MB of DDR2 memory running at 400 MHz through a 128-bit bus. It also is made up of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 can be applied in one second. This is calculated by multiplying the total amount of texture units by the core 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 applied per second.

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