GeForce 8600 GT 1GB GDDR3 vs GeForce GT 320

Intro

The GeForce 8600 GT 1GB GDDR3 comes with clock speeds of 540 MHz on the GPU, and 700 MHz on the 1024 MB of GDDR3 memory. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Compare those specifications to the GeForce GT 320, which has a core clock frequency of 540 MHz and a GDDR3 memory frequency of 790 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 72 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320 43 Watts
GeForce 8600 GT 1GB GDDR3 47 Watts
Difference: 4 Watts (9%)

Memory Bandwidth

Performance-wise, the GeForce GT 320 should in theory be just a bit better than the GeForce 8600 GT 1GB GDDR3 overall. (explain)

GeForce GT 320 25280 MB/sec
GeForce 8600 GT 1GB GDDR3 22400 MB/sec
Difference: 2880 (13%)

Texel Rate

The GeForce GT 320 will be a lot (more or less 50%) more effective at texture filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

GeForce GT 320 12960 Mtexels/sec
GeForce 8600 GT 1GB 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 capable of handling 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 (counted in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
