GeForce 8600 GT 512MB GDDR3 vs GeForce GT 320

Intro

The GeForce 8600 GT 512MB GDDR3 uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The GDDR3 RAM is set to run at a speed of 700 MHz on this particular model. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Compare that to the GeForce GT 320, which makes use of a 40 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 memory runs at a speed of 790 MHz on this specific card. It features 72 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320 43 Watts
GeForce 8600 GT 512MB GDDR3 47 Watts
Difference: 4 Watts (9%)

Memory Bandwidth

The GeForce GT 320 should theoretically perform a small bit faster than the GeForce 8600 GT 512MB GDDR3 overall. (explain)

GeForce GT 320 25280 MB/sec
GeForce 8600 GT 512MB GDDR3 22400 MB/sec
Difference: 2880 (13%)

Texel Rate

The GeForce GT 320 should be much (approximately 50%) more effective at AF than the GeForce 8600 GT 512MB GDDR3. (explain)

GeForce GT 320 12960 Mtexels/sec
GeForce 8600 GT 512MB GDDR3 8640 Mtexels/sec
Difference: 4320 (50%)

Pixel Rate

Both cards have the exact same pixel rate, so theoretically they should be equally good at at FSAA, 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 maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
