GeForce 8600 GT 1GB GDDR3 vs GeForce 8600 GT 512MB DDR2

Intro

The GeForce 8600 GT 1GB GDDR3 features a core clock speed of 540 MHz and a GDDR3 memory frequency of 700 MHz. It also uses a 128-bit bus, and uses a 80 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the GeForce 8600 GT 512MB DDR2, which comes with a clock frequency of 540 MHz and a DDR2 memory frequency of 400 MHz. It also features a 128-bit memory bus, and makes use of a 80 nm design. It features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the GeForce 8600 GT 1GB GDDR3 should be much faster than the GeForce 8600 GT 512MB DDR2 in general. (explain)

GeForce 8600 GT 1GB GDDR3 22400 MB/sec
GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 9600 (75%)

Texel Rate

Both cards have exactly the same texel rate, so theoretically they should be equally good at at anisotropic filtering. (explain)

Pixel Rate

Both cards have exactly the same pixel fill rate, so theoretically they should be equally good at at anti-aliasing, and be able to handle the same 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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
