Quote: To retain modest pricing, it’s common to see lower-end graphics cards equipped with either DDR2 or DDR3. That design choice, though, can have a major effect on performance, something that’s proven twice over with AMD’s Radeon HD 5550 and HD 5570, both of which have just been upgraded with a move to GDDR5 memory.
