Compare any two graphics cards:
GeForce 9800 GTX vs Radeon HD 5550
IntroThe GeForce 9800 GTX uses a 65 nm design. nVidia has set the core frequency at 675 MHz. The GDDR3 memory works at a frequency of 1100 MHz on this specific model. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.
Compare those specifications to the Radeon HD 5550, which comes with a GPU core clock speed of 550 MHz, and 512 MB of DDR2 memory set to run at 400 MHz through a 128-bit bus. It also is comprised of 320(64x5) Stream Processors, 16 TAUs, and 8 Raster Operation Units.

GeForce 9800 GTX wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the GeForce 9800 GTX wins overall, by 90 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.
Power Usage and Theoretical Benchmarks
The GeForce 9800 GTX, in theory, should be a lot faster than the Radeon HD 5550 in general. (explain)
Texel RateThe GeForce 9800 GTX should be quite a bit (more or less 391%) more effective at anisotropic filtering than the Radeon HD 5550. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 9800 GTX 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
