GeForce 8500 GT vs Radeon HD 5570
Intro
The GeForce 8500 GT uses a 80 nm design. nVidia has clocked the core speed at 450 MHz. The DDR2 memory works at a frequency of 400 MHz on this particular card. It features 16 SPUs along with 8 TAUs and 4 ROPs.Compare that to the Radeon HD 5570, which comes with a GPU core clock speed of 650 MHz, and 512 MB of DDR3 memory running at 900 MHz through a 128-bit bus. It also features 400(80x5) SPUs, 20 Texture Address Units, and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
