GeForce 8600 GT 256MB DDR2 vs GeForce GTX 480

Intro

The GeForce 8600 GT 256MB DDR2 has a core clock speed of 540 MHz and a DDR2 memory speed of 400 MHz. It also features a 128-bit bus, and uses a 80 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.

Compare those specs to the GeForce GTX 480, which comes with core speeds of 700 MHz on the GPU, and 924 MHz on the 1536 MB of GDDR5 RAM. It features 480 SPUs as well as 60 TAUs and 48 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 per second. This figure 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 video 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 chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
