Compare any two graphics cards:
GeForce 9800 GT 512MB vs GeForce GTX 550 Ti
IntroThe GeForce 9800 GT 512MB has a core clock frequency of 600 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit memory bus, and uses a 65/55 nm design. It is comprised of 112 SPUs, 56 Texture Address Units, and 16 ROPs.Compare all of that to the GeForce GTX 550 Ti, which features clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs along with 32 TAUs and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 550 Ti should perform much faster than the GeForce 9800 GT 512MB in general. (explain)
Texel RateThe GeForce 9800 GT 512MB is a bit (approximately 17%) faster with regards to texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 550 Ti is the winner, and very much so. (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 max amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
