GeForce 9500 GT 1GB GDDR3 vs GeForce 9500 GT 512MB GDDR3
Intro
The GeForce 9500 GT 1GB GDDR3 comes with a GPU core clock speed of 550 MHz, and the 1024 MB of GDDR3 memory is set to run at 800 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 TAUs, and 8 ROPs.Compare those specs to the GeForce 9500 GT 512MB GDDR3, which features clock speeds of 550 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 32 SPUs as well as 16 TAUs and 8 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)
Texel Rate
Both cards have exactly the same texel fill rate, so theoretically they should perform equally good at at AF. (explain)Pixel Rate
Both cards have the exact same pixel fill rate, so in theory they should be equally good at at full screen anti-aliasing, 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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR 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 texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the 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 clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
