GeForce 810M vs GeForce 8600 GT 512MB DDR2

Intro

The GeForce 810M comes with a core clock speed of 738 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It is comprised of 48 SPUs, 8 Texture Address Units, and 4 ROPs.

Compare all that to the GeForce 8600 GT 512MB DDR2, which features GPU clock speed of 540 MHz, and 512 MB of DDR2 memory set to run at 400 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
