Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6670 (OEM)
IntroThe GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has set the core speed at 900 MHz. The GDDR5 memory works at a frequency of 1026 MHz on this particular card. It features 192 SPUs as well as 32 TAUs and 24 ROPs.
Compare those specifications to the Radeon HD 6670 (OEM), which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this specific model. It features 480 SPUs as well as 24 TAUs and 8 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 550 Ti, in theory, should perform much faster than the Radeon HD 6670 (OEM) in general. (explain)
Texel RateThe GeForce GTX 550 Ti will be much (approximately 50%) more effective at anisotropic filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 550 Ti is the winner, 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 information (in units of MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core 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 applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's 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 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 get to the maximum fill rate.
