Compare any two graphics cards:
GeForce 9800 GTX vs Radeon HD 5550
IntroThe GeForce 9800 GTX makes use of a 65 nm design. nVidia has set the core frequency at 675 MHz. The GDDR3 memory is set to run at a frequency of 1100 MHz on this card. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.
Compare that to the Radeon HD 5550, which uses a 40 nm design. AMD has set the core frequency at 550 MHz. The DDR2 RAM runs at a speed of 400 MHz on this model. It features 320(64x5) SPUs as well as 16 TAUs and 8 Rasterization Operator 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
Theoretically speaking, the GeForce 9800 GTX should perform a lot faster than the Radeon HD 5550 overall. (explain)
Texel RateThe GeForce 9800 GTX should be quite a bit (more or less 391%) faster with regards to anisotropic filtering than the Radeon HD 5550. (explain)
Pixel RateThe GeForce 9800 GTX should be a lot (about 145%) better at FSAA than the Radeon HD 5550, and also able to handle higher resolutions more effectively. (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 max amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 that the graphics card could 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 speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
