Compare any two graphics cards:
GeForce 9800 GT 1GB vs GeForce GTX 550 Ti
IntroThe GeForce 9800 GT 1GB features a 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 features 112 SPUs, 56 TAUs, and 16 Raster Operation Units.
Compare those specs to the GeForce GTX 550 Ti, which has a clock frequency of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also uses a 192-bit memory bus, and uses a 40 nm design. It features 192 SPUs, 32 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 550 Ti should in theory be much better than the GeForce 9800 GT 1GB overall. (explain)
Texel RateThe GeForce 9800 GT 1GB should be a bit (approximately 17%) faster with regards to anisotropic filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 550 Ti is a lot (more or less 125%) faster with regards to FSAA than the GeForce 9800 GT 1GB, and will be capable of handling higher screen 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 can be applied per second. This is worked out by multiplying the total texture units of the card by the core clock 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 per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
