GeForce 8800 GTS (G80) 640MB vs Radeon HD 5770

Intro

The GeForce 8800 GTS (G80) 640MB comes with core clock speeds of 513 MHz on the GPU, and 792 MHz on the 640 MB of GDDR3 memory. It features 96 SPUs along with 48 TAUs and 20 Rasterization Operator Units.

Compare all that to the Radeon HD 5770, which makes use of a 40 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 RAM is set to run at a speed of 1200 MHz on this model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core 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 is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
