Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs GeForce GT 320
IntroThe GeForce 9500 GT 1GB GDDR3 has a clock frequency of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also uses a 128-bit bus, and uses a 55 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare all that to the GeForce GT 320, which features a core clock frequency of 540 MHz and a GDDR3 memory speed of 790 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It features 72 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 9500 GT 1GB GDDR3 should in theory be just a bit better than the GeForce GT 320 in general. (explain)
Texel RateThe GeForce GT 320 is quite a bit (approximately 47%) faster with regards to AF than the GeForce 9500 GT 1GB GDDR3. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 9500 GT 1GB GDDR3 is superior to the GeForce GT 320, but it probably won't make a huge difference. (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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the 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 most 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 calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
