Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 570
IntroThe GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 RAM is set to run at a speed of 1026 MHz on this specific card. It features 192 SPUs along with 32 Texture Address Units and 24 ROPs.
Compare that to the GeForce GTX 570, which comes with a core clock speed of 732 MHz and a GDDR5 memory frequency of 950 MHz. It also uses a 320-bit bus, and uses a 40 nm design. It is comprised of 480 SPUs, 60 TAUs, and 40 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 570 should be much faster than the GeForce GTX 550 Ti overall. (explain)
Texel RateThe GeForce GTX 570 will be much (more or less 53%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 570 should be quite a bit (more or less 36%) more effective at AA than the GeForce GTX 550 Ti, and able to handle higher 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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
