GeForce 8800 GTS (G80) 320MB vs Radeon HD 3850 1GB

Intro

The GeForce 8800 GTS (G80) 320MB makes use of a 90 nm design. nVidia has set the core speed at 513 MHz. The GDDR3 memory runs at a frequency of 792 MHz on this particular model. It features 96 SPUs as well as 48 Texture Address Units and 20 ROPs.

Compare those specs to the Radeon HD 3850 1GB, which features clock speeds of 668 MHz on the GPU, and 828 MHz on the 1024 MB of GDDR3 memory. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many 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.
