GeForce 8800 GT 512MB vs GeForce 9800 GT 512MB


Intro

The GeForce 8800 GT 512MB has a GPU clock speed of 600 MHz, and the 512 MB of GDDR3 RAM runs at 900 MHz through a 256-bit bus. It also is comprised of 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the GeForce 9800 GT 512MB, which uses a 65/55 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this model. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform the same. (explain)

Texel Rate

Both cards have exactly the same texel fill rate, so in theory they should be equally good at at AF. (explain)

Pixel Rate

Both cards have exactly the same pixel rate, so theoretically they should be equally good at at AA, and be capable of handling the same screen resolutions. (explain)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most 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 amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
