GeForce 8600 GT 1GB DDR2 vs Radeon HD 6450 (OEM)
Intro
The GeForce 8600 GT 1GB DDR2 makes use of a 80 nm design. nVidia has clocked the core speed at 540 MHz. The DDR2 memory works at a frequency of 400 MHz on this specific card. It features 32 SPUs along with 16 TAUs and 8 ROPs.Compare all of that to the Radeon HD 6450 (OEM), which makes use of a 40 nm design. AMD has clocked the core speed at 625 MHz. The GDDR3 memory is set to run at a speed of 800 MHz on this particular model. It features 160 SPUs as well as 8 TAUs and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number 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 amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
