GeForce 8600 GT 512MB DDR2 vs GeForce GT 130

Intro

The GeForce 8600 GT 512MB DDR2 comes with core clock speeds of 540 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Compare those specs to the GeForce GT 130, which has a core clock speed of 500 MHz and a DDR2 memory frequency of 250 MHz. It also uses a 192-bit bus, and uses a 55 nm design. It is comprised of 48 SPUs, 24 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
