GeForce 8600 GT 1GB GDDR3 vs GeForce 9600 GSO 768MB

Intro

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

Compare those specifications to the GeForce 9600 GSO 768MB, which comes with GPU clock speed of 550 MHz, and 768 MB of GDDR3 memory running at 800 MHz through a 192-bit bus. It also is made up of 96 SPUs, 48 TAUs, and 12 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB GDDR3 47 Watts
GeForce 9600 GSO 768MB 84 Watts
Difference: 37 Watts (79%)

Memory Bandwidth

As far as performance goes, the GeForce 9600 GSO 768MB should theoretically be quite a bit superior to the GeForce 8600 GT 1GB GDDR3 overall. (explain)

GeForce 9600 GSO 768MB 38400 MB/sec
GeForce 8600 GT 1GB GDDR3 22400 MB/sec
Difference: 16000 (71%)

Texel Rate

The GeForce 9600 GSO 768MB should be a lot (approximately 206%) faster with regards to anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

GeForce 9600 GSO 768MB 26400 Mtexels/sec
GeForce 8600 GT 1GB GDDR3 8640 Mtexels/sec
Difference: 17760 (206%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 9600 GSO 768MB is the winner, and very much so. (explain)

GeForce 9600 GSO 768MB 6600 Mpixels/sec
GeForce 8600 GT 1GB GDDR3 4320 Mpixels/sec
Difference: 2280 (53%)

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 largest amount of information (in units of MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out 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 amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
