Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce 9800 GT 1GB
IntroThe GeForce 9500 GT DDR2 comes with a GPU clock speed of 550 MHz, and the 256 MB of DDR2 memory runs at 500 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare all of that to the GeForce 9800 GT 1GB, which features a core clock speed of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit bus, and uses a 65/55 nm design. It is comprised of 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 9800 GT 1GB should perform much faster than the GeForce 9500 GT DDR2 overall. (explain)
Texel RateThe GeForce 9800 GT 1GB will be a lot (more or less 282%) more effective at texture filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 9800 GT 1GB is the winner, by a large margin. (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 maximum amount of information (measured in MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could 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 card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
