GeForce 8800 GTX vs Radeon HD 5750 512MB

Intro

The GeForce 8800 GTX makes use of a 90 nm design. nVidia has clocked the core speed at 575 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this specific model. It features 128 SPUs as well as 64 TAUs and 24 Rasterization Operator Units.

Compare those specs to the Radeon HD 5750 512MB, which uses a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 memory runs at a speed of 1150 MHz on this card. It features 720(144x5) SPUs along with 36 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
