GeForce 8600 GT 512MB GDDR3 vs GeForce GTX 570

Intro

The GeForce 8600 GT 512MB GDDR3 uses a 80 nm design. nVidia has set the core speed at 540 MHz. The GDDR3 RAM works at a speed of 700 MHz on this particular model. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Compare all of that to the GeForce GTX 570, which uses a 40 nm design. nVidia has clocked the core speed at 732 MHz. The GDDR5 memory works at a speed of 950 MHz on this card. It features 480 SPUs as well as 60 TAUs and 40 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
