GeForce 8600 GT 1GB GDDR3 vs GeForce 920M
Intro
The GeForce 8600 GT 1GB GDDR3 makes use of a 80 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 memory is set to run at a speed of 700 MHz on this particular card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the GeForce 920M, which has GPU clock speed of 954 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 64-bit bus. It also features 384 SPUs, 32 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated 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 in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
