GeForce 8600 GT 512MB DDR2 vs Geforce GTX 760

Intro

The GeForce 8600 GT 512MB DDR2 comes with a GPU core clock speed of 540 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare that to the Geforce GTX 760, which uses a 28 nm design. nVidia has clocked the core speed at 980 MHz. The GDDR5 memory works at a speed of 1502 MHz on this particular model. It features 1152 SPUs as well as 96 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
