GeForce 8800 GTS (G80) 320MB vs GeForce 8800 GTS (G92)

Intro

The GeForce 8800 GTS (G80) 320MB features a GPU core speed of 513 MHz, and the 320 MB of GDDR3 memory is set to run at 792 MHz through a 320-bit bus. It also is comprised of 96 SPUs, 48 Texture Address Units, and 20 ROPs.

Compare those specifications to the GeForce 8800 GTS (G92), which comes with a GPU core clock speed of 650 MHz, and 512 MB of GDDR3 memory running at 970 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTS (G92) 135 Watts
GeForce 8800 GTS (G80) 320MB 143 Watts
Difference: 8 Watts (6%)

Memory Bandwidth

In theory, the GeForce 8800 GTS (G80) 320MB should be just a bit faster than the GeForce 8800 GTS (G92) overall. (explain)

GeForce 8800 GTS (G80) 320MB 63360 MB/sec
GeForce 8800 GTS (G92) 62080 MB/sec
Difference: 1280 (2%)

Texel Rate

The GeForce 8800 GTS (G92) is quite a bit (approximately 69%) better at texture filtering than the GeForce 8800 GTS (G80) 320MB. (explain)

GeForce 8800 GTS (G92) 41600 Mtexels/sec
GeForce 8800 GTS (G80) 320MB 24624 Mtexels/sec
Difference: 16976 (69%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 8800 GTS (G92) is the winner, but it probably won't make a huge difference. (explain)

GeForce 8800 GTS (G92) 10400 Mpixels/sec
GeForce 8800 GTS (G80) 320MB 10260 Mpixels/sec
Difference: 140 (1%)

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 maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
