GeForce 8800 GT 512MB vs GeForce 8800 GTS (G92)

Intro

The GeForce 8800 GT 512MB comes with a clock speed of 600 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit bus, and uses a 65 nm design. It is comprised of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 512MB 105 Watts
GeForce 8800 GTS (G92) 135 Watts
Difference: 30 Watts (29%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GTS (G92) will be 8% quicker than the GeForce 8800 GT 512MB overall, because of its greater data rate. (explain)

GeForce 8800 GTS (G92) 62080 MB/sec
GeForce 8800 GT 512MB 57600 MB/sec
Difference: 4480 (8%)

Texel Rate

The GeForce 8800 GTS (G92) is a lot (more or less 24%) better at anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

GeForce 8800 GTS (G92) 41600 Mtexels/sec
GeForce 8800 GT 512MB 33600 Mtexels/sec
Difference: 8000 (24%)

Pixel Rate

The GeForce 8800 GTS (G92) should be a little bit (more or less 8%) faster with regards to AA than the GeForce 8800 GT 512MB, and also able to handle higher screen resolutions without losing too much performance. (explain)

GeForce 8800 GTS (G92) 10400 Mpixels/sec
GeForce 8800 GT 512MB 9600 Mpixels/sec
Difference: 800 (8%)

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 (measured in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling 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 video card can possibly write to the local memory per second - measured in millions of pixels per second. The number 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
