ATI Radeon HD 5500 Series GDDR5

  • Brand: ATI
  • Category: Display Cards

The recently released Radeon HD 5500 series cards differed from their predecessors in only one meaningful way—they were equipped with GDDR5 memory. The original 5500 series cards sported GDDR3 or GDDR2 memory. The move to GDDR5 allowed AMD to crank the memory clock speed up a bit, which would have a positive impact on overall performance.

We’ve got both the Radeon HD 5550 and Radeon HD 5570 GDDR5 edition graphics cards in house and have taken them for a spin around the lab with an assortment of popular games and benchmarks. Take a look at the pages ahead to see just what a sub-$90 graphics card can get you these days…

While these are OK for some uses
While these are OK for some uses, their introduction pales along side the new GTX460 class of cards from NVIDIA. Yeah, apples and oranges, but 'cmon ATI, how about a real splash in the marketplace? What'cha got up your sleeves?

Don't blame ATI
Don't blame ATI... they don't exist anymore... it's all AMD's fault :-)

Both cards should be nice for a HTPC or something basic. Me personally I would have to pony up a few more bucks and step up to the 5700 series at the very least.

great card
great card for gaming, but useless for movies. I'm totally baffled as to why they call it Radeon HD when it doesn't work with HD DVD's or Blu-Ray movies.
