GeForce 8600 GT 512MB DDR2 vs Geforce GTX 670

Intro

The GeForce 8600 GT 512MB DDR2 makes use of a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 memory runs at a frequency of 400 MHz on this card. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Compare those specs to the Geforce GTX 670, which has GPU core speed of 915 MHz, and 2048 MB of GDDR5 memory set to run at 1500 MHz through a 256-bit bus. It also features 1344 SPUs, 112 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
