GeForce 9600 GT 1GB vs GeForce 9800 GT 512MB

Intro

The GeForce 9600 GT 1GB uses a 65/55 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this particular model. It features 64 SPUs along with 32 TAUs and 16 ROPs.

Compare those specifications to the GeForce 9800 GT 512MB, which features clock speeds of 600 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 112 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 1GB 95 Watts
GeForce 9800 GT 512MB 105 Watts
Difference: 10 Watts (11%)

Memory Bandwidth

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

Texel Rate

The GeForce 9800 GT 512MB should be quite a bit (about 62%) more effective at texture filtering than the GeForce 9600 GT 1GB. (explain)

GeForce 9800 GT 512MB 33600 Mtexels/sec
GeForce 9600 GT 1GB 20800 Mtexels/sec
Difference: 12800 (62%)

Pixel Rate

The GeForce 9600 GT 1GB will be a small bit (more or less 8%) more effective at anti-aliasing than the GeForce 9800 GT 512MB, and able to handle higher resolutions without losing too much performance. (explain)

GeForce 9600 GT 1GB 10400 Mpixels/sec
GeForce 9800 GT 512MB 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 max amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
