Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 5870
IntroThe GeForce GTX 550 Ti comes with a core clock frequency of 900 MHz and a GDDR5 memory speed of 1026 MHz. It also makes use of a 192-bit bus, and makes use of a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 24 Raster Operation Units.
Compare those specs to the Radeon HD 5870, which uses a 40 nm design. ATi has clocked the core speed at 850 MHz. The GDDR5 memory works at a speed of 1200 MHz on this specific model. It features 1600(320x5) SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon HD 5870 should be much faster than the GeForce GTX 550 Ti in general. (explain)
Texel RateThe Radeon HD 5870 will be quite a bit (approximately 136%) better at anisotropic filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 5870 is superior to the GeForce GTX 550 Ti, by far. (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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on 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 ability to reach the max fill rate.
