Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 5870
IntroThe GeForce GTX 550 Ti uses a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 RAM is set to run at a frequency of 1026 MHz on this specific model. It features 192 SPUs along with 32 TAUs and 24 Rasterization Operator Units.
Compare those specs to the Radeon HD 5870, which makes use of a 40 nm design. ATi has set the core speed at 850 MHz. The GDDR5 RAM works at a speed of 1200 MHz on this particular model. It features 1600(320x5) SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 5870 should in theory be quite a bit faster than the GeForce GTX 550 Ti in general. (explain)
Texel RateThe Radeon HD 5870 should be much (approximately 136%) better at anisotropic filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe Radeon HD 5870 is quite a bit (about 26%) faster with regards to AA than the GeForce GTX 550 Ti, and 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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
