GeForce GTX 550 Ti vs Radeon HD 6850
Intro
The GeForce GTX 550 Ti has a GPU core speed of 900 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1026 MHz through a 192-bit bus. It also features 192 Stream Processors, 32 Texture Address Units, and 24 Raster Operation Units.Compare that to the Radeon HD 6850, which makes use of a 40 nm design. AMD has clocked the core speed at 775 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific model. It features 960 SPUs as well as 48 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, 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 that the graphics chip 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 ROPs by the the card's 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.

It is very important to remember some games prefer AMD cards while other games prefer NVIDIA. For example the HD6850 plays planetside 2 like a dream on 1080p medium high settings, I have yet to try max settings. But on other games like RIFT you might have a slight performance boost with the 550ti I cannot go into details right now but just my 2 cents.Most of the time poorly desgined mmorpgs like rift or pwi use peoples internet speed more then there gpu. Other games that are well designed like wow and gw2 use your gpu more efficiently.
