Compare any two graphics cards:
GeForce 8500 GT vs GeForce 9500 GT DDR2
IntroThe GeForce 8500 GT comes with a GPU core speed of 450 MHz, and the 512 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also features 16 Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.Compare those specs to the GeForce 9500 GT DDR2, which has GPU clock speed of 550 MHz, and 256 MB of DDR2 memory set to run at 500 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9500 GT DDR2 should be 25% faster than the GeForce 8500 GT in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce 9500 GT DDR2 should be a lot (more or less 144%) better at texture filtering than the GeForce 8500 GT. (explain)
Pixel RateThe GeForce 9500 GT DDR2 should be a lot (approximately 144%) faster with regards to full screen anti-aliasing than the GeForce 8500 GT, and also able to handle higher resolutions better. (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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per 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 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 potential to get to the max fill rate.
