Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce 9800 GT 1GB
IntroThe GeForce 9500 GT DDR2 comes with a core clock speed of 550 MHz and a DDR2 memory speed of 500 MHz. It also features a 128-bit bus, and makes use of a 65 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare that to the GeForce 9800 GT 1GB, which features a core clock frequency 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 made up of 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9800 GT 1GB will be 260% faster than the GeForce 9500 GT DDR2 overall, because of its greater data rate. (explain)
Texel RateThe GeForce 9800 GT 1GB should be a lot (approximately 282%) faster with regards to texture filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateThe GeForce 9800 GT 1GB is a lot (more or less 118%) faster with regards to anti-aliasing than the GeForce 9500 GT DDR2, and should be capable of handling higher screen resolutions without slowing down too much. (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 largest amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 are applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 get to the max fill rate.
