Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GTX 660 Ti has a core clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 192-bit bus, and uses a 28 nm design. It is comprised of 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.
Compare all of that to the Radeon HD 6570 (OEM) 2GB, which makes use of a 40 nm design. ATi has clocked the core speed at 650 MHz. The GDDR5 memory works at a speed of 1000 MHz on this particular card. It features 480 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 660 Ti should perform a lot faster than the Radeon HD 6570 (OEM) 2GB overall. (explain)
Texel RateThe GeForce GTX 660 Ti is quite a bit (about 557%) more effective at texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 660 Ti is superior to the Radeon HD 6570 (OEM) 2GB, 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.
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 (in units of megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the 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 bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
