Compare any two graphics cards:
GeForce 9800 GT 512MB vs GeForce GT 430 1GB
IntroThe GeForce 9800 GT 512MB comes with a clock speed of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 256-bit bus, and uses a 65/55 nm design. It features 112 SPUs, 56 TAUs, and 16 Raster Operation Units.Compare those specs to the GeForce GT 430 1GB, which comes with a core clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 16 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9800 GT 512MB should perform much faster than the GeForce GT 430 1GB overall. (explain)
Texel RateThe GeForce 9800 GT 512MB should be much (approximately 200%) better at texture filtering than the GeForce GT 430 1GB. (explain)
Pixel RateThe GeForce 9800 GT 512MB is much (more or less 243%) faster with regards to full screen anti-aliasing than the GeForce GT 430 1GB, and also able to handle higher resolutions while still performing well. (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 data (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
