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

Intro

The GeForce 8600 GT 512MB DDR2 uses a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 RAM works at a frequency of 400 MHz on this particular card. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.

Compare that to the GeForce 8600 GT 512MB GDDR3, which uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The GDDR3 memory runs at a speed of 700 MHz on this particular model. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the GeForce 8600 GT 512MB GDDR3 should perform quite a bit faster than the GeForce 8600 GT 512MB DDR2 overall. (explain)

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

Texel Rate

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

Pixel Rate

Both cards have exactly the same pixel fill rate, so theoretically they should perform equally good at at AA, and be able to handle 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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can 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 - also called 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 max fill rate.
