GeForce 8600 GTS vs Radeon HD 3650 512MB

Intro

The GeForce 8600 GTS uses a 80 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR3 RAM is set to run at a speed of 1000 MHz on this card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare all that to the Radeon HD 3650 512MB, which features a GPU core clock speed of 725 MHz, and 512 MB of GDDR3 memory set to run at 800 MHz through a 128-bit bus. It also is comprised of 120(24x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at 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 write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
