GeForce 8800 GT 1GB vs GeForce 9600 GT 512MB

Intro

The GeForce 8800 GT 1GB makes use of a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this particular card. It features 112 SPUs along with 56 Texture Address Units and 16 ROPs.

Compare those specs to the GeForce 9600 GT 512MB, which uses a 65/55 nm design. nVidia has set the core speed at 650 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this card. It features 64 SPUs along with 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 512MB 95 Watts
GeForce 8800 GT 1GB 105 Watts
Difference: 10 Watts (11%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The GeForce 8800 GT 1GB should be quite a bit (approximately 62%) more effective at texture filtering than the GeForce 9600 GT 512MB. (explain)

GeForce 8800 GT 1GB 33600 Mtexels/sec
GeForce 9600 GT 512MB 20800 Mtexels/sec
Difference: 12800 (62%)

Pixel Rate

The GeForce 9600 GT 512MB is just a bit (more or less 8%) faster with regards to anti-aliasing than the GeForce 8800 GT 1GB, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce 9600 GT 512MB 10400 Mpixels/sec
GeForce 8800 GT 1GB 9600 Mpixels/sec
Difference: 800 (8%)

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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
