Compare any two graphics cards:
GeForce 9800 GT 512MB vs GeForce GT 320
IntroThe GeForce 9800 GT 512MB makes use of a 65/55 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this specific model. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the GeForce GT 320, which comes with GPU clock speed of 540 MHz, and 1024 MB of GDDR3 RAM running at 790 MHz through a 128-bit bus. It also is comprised of 72 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 9800 GT 512MB should in theory be quite a bit superior to the GeForce GT 320 in general. (explain)
Texel RateThe GeForce 9800 GT 512MB will be quite a bit (approximately 159%) more effective at anisotropic filtering than the GeForce GT 320. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 9800 GT 512MB 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 largest amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, 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 calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
