GeForce 8800 GT 512MB vs Radeon HD 6570 (OEM) 1GB
Intro
The GeForce 8800 GT 512MB makes use of a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory works at a speed of 900 MHz on this particular model. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 6570 (OEM) 1GB, which makes use of a 40 nm design. AMD has clocked the core speed at 650 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this card. It features 480 SPUs along with 24 TAUs and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 in a second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
