Radeon 

ATI's graphics cards line up. Currently their most high end is a 512 MB Radeon X850 XT PE Pci express. I think. Most people probably are still currently using 2nd generation radeons like Radeon 9xxxs. Rival versus GeForce by nVidia.

I have a Radeon 9800 pro, and it gets the job done and then some.

Radeon 

Radeon is a toxic and fart like smelling gas which is used originally by ATI ( now an AMD property but still behaves as an independent company ) in their third class and cheap graphics cards hence the name Radeon graphics which runs hot and loud and are known to burn out power supplies of PCs quite often.

Due to completely cheap and poor quality of Radeon gas graphics, Radeon gas phrase is widely used to describe something which is completely of poor quality and worthless and don't have much value or benefit and a cheap company or a product in a category. This phrase is also used to describe a product which is just insanely overpriced and don't offer much value or features than its predecessor

Sony's PC division was it's Radeon gas, so they sold to other company.
Samsung's Hard Disk division was it's Radeon gas as it did not make much profit, so they sold their Radeon gas to Seagate in 2011.
Xiaomi phones are Radeon gas of the mobile market.
Apple's new 2019 Mac Pro is Radeon gas because it's uses cheap Radeon gas graphics.

Radeon 3870x2 

The name of the latest (as of February 17, 2008) ATi graphics cards. It has dual GPU's (graphic processing unit) and supports a second card by using "Crossfire" also know as "X-fire" and "CrossfireX".
This is currently one of the best cards on the market, comparable to the "Geforce 8800 Ultra", a $600-750 card by Nvidia, for an affordable $349.
The card supports Pci express x16 2.0, which none of the current Nivian cards support, has a default clock speed of 825mhz, has a full gig of onboard memory, and is rather large.

Person 1 "hey, I just got the new Radeon 3870x2, it runs like a charm and looks great on maxed out settings!"

Person 2 "yeah? Well my 8800 gtx cost more, so it must look better, right?"

Person 1 "Why, again, are we friends?"
