GeForce 8500 GT vs Radeon HD 5570
Intro
The GeForce 8500 GT has a clock speed of 450 MHz and a DDR2 memory frequency of 400 MHz. It also uses a 128-bit memory bus, and makes use of a 80 nm design. It is made up of 16 SPUs, 8 Texture Address Units, and 4 ROPs.Compare that to the Radeon HD 5570, which uses a 40 nm design. AMD has set the core frequency at 650 MHz. The DDR3 RAM is set to run at a frequency of 900 MHz on this specific model. It features 400(80x5) SPUs along with 20 Texture Address Units and 8 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 are processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the 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 write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
