GeForce GTX 550 Ti vs Radeon HD 6770 1GB
Intro
The GeForce GTX 550 Ti comes with a GPU core speed of 900 MHz, and the 1024 MB of GDDR5 RAM runs at 1026 MHz through a 192-bit bus. It also features 192 Stream Processors, 32 TAUs, and 24 ROPs.Compare all of that to the Radeon HD 6770 1GB, which comes with a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It features 800 SPUs, 40 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high 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 number of texture units of the card by the core clock 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 processed in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.

The 550 generally outperforms This ATI card but it is a bit more expensive. The 550 is somewhere in between the 6770 and the 6850.. If you have a little extra cash to fork out. I would suggest getting a ATI HD 6850 Radeon. But as of this comparison with the 6770. Gtx 550 Ti is most definitely the winner.
People looking for a Graphics card. Should already have gotten a decent power supply(PSU) first. Power consumption should not be an issue.
hey admin I think that your specs on the 6770 are differing from the 6770s we know today, and changing them would ensure a fair comparison 🙂 btw good job on the website

the benchmark that you are showing is wrong, the 560 is at 33fps not the 550, the 550 is at 22, the 6770 is at 19 from toms hardware(these are from the specific cards i was looking at) http://www.tomshardware.com/charts/2011-gaming-graphics-charts/compare,2661.html?prod%5B4973%5D=on&prod%5B5248%5D=on
Indeed you are correct. No idea how that happened, seems all the numbers in that entire benchmark got screwed up. I've deleted the whole benchmark and will redo later.
