Compare any two graphics cards:
GeForce 9800 GTX vs Radeon HD 5550
IntroThe GeForce 9800 GTX has a clock speed of 675 MHz and a GDDR3 memory frequency of 1100 MHz. It also features a 256-bit bus, and makes use of a 65 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 ROPs.
Compare those specs to the Radeon HD 5550, which has a GPU core clock speed of 550 MHz, and 512 MB of DDR2 RAM running at 400 MHz through a 128-bit bus. It also features 320(64x5) SPUs, 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
Performance-wise, the GeForce 9800 GTX should in theory be a lot superior to the Radeon HD 5550 overall. (explain)
Texel RateThe GeForce 9800 GTX is much (more or less 391%) more effective at AF than the Radeon HD 5550. (explain)
Pixel RateThe GeForce 9800 GTX is a lot (about 145%) faster with regards to full screen anti-aliasing than the Radeon HD 5550, and also should be capable of handling higher screen resolutions without losing too much performance. (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: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR 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 anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock 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 in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
