Compare any two graphics cards:
GeForce 9800 GTX vs Radeon HD 5550
IntroThe GeForce 9800 GTX has core speeds of 675 MHz on the GPU, and 1100 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.
Compare that to the Radeon HD 5550, which makes use of a 40 nm design. AMD has set the core speed at 550 MHz. The DDR2 RAM works at a frequency of 400 MHz on this specific card. It features 320(64x5) SPUs along with 16 Texture Address Units and 8 ROPs.

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 will be much (about 391%) faster with regards to texture filtering than the Radeon HD 5550. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce 9800 GTX is a better choice, 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.
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 max amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
