GeForce 8500 GT vs Radeon HD 5570
Intro
The GeForce 8500 GT uses a 80 nm design. nVidia has set the core frequency at 450 MHz. The DDR2 memory works at a frequency of 400 MHz on this particular model. It features 16 SPUs as well as 8 TAUs and 4 ROPs.Compare all of that to the Radeon HD 5570, which makes use of a 40 nm design. AMD has clocked the core speed at 650 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this specific model. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 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 higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core 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 processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
