GeForce 8600 GT 1GB DDR2 vs GeForce 920M
Intro
The GeForce 8600 GT 1GB DDR2 has a core clock speed of 540 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of a 128-bit memory bus, and uses a 80 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare all that to the GeForce 920M, which uses a 28 nm design. nVidia has set the core speed at 954 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this card. It features 384 SPUs along with 32 TAUs and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount 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 one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
