Compare any two graphics cards:
GeForce 9800 GTX vs Radeon HD 5550
IntroThe GeForce 9800 GTX features core speeds of 675 MHz on the GPU, and 1100 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.
Compare those specs to the Radeon HD 5550, which features core speeds of 550 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. 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
The GeForce 9800 GTX should theoretically be quite a bit faster than the Radeon HD 5550 in general. (explain)
Texel RateThe GeForce 9800 GTX should be much (approximately 391%) faster with regards to anisotropic filtering than the Radeon HD 5550. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 9800 GTX is a better choice, 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: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high 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 amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant 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.
