GeForce 8600 GT 512MB GDDR3 vs Radeon HD 3650 512MB

Intro

The GeForce 8600 GT 512MB GDDR3 makes use of a 80 nm design. nVidia has set the core speed at 540 MHz. The GDDR3 memory runs at a frequency of 700 MHz on this model. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare all of that to the Radeon HD 3650 512MB, which features a core clock speed of 725 MHz and a GDDR3 memory speed of 800 MHz. It also features a 128-bit bus, and uses a 55 nm design. It is comprised of 120(24x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
