We mentioned in our standalone review that there was
really more to the HD 5970 than just what meets the eye. We also covered the
fact that ATI have kind of pushed this whole thing about the HD 5970 being
"Unlocked." At first glance it's a little hard to figure what exactly
ATI mean when they're saying this. Generally speaking, in the computer world
the term "Unlocked" tends to refer to a CPU and the fact that it is
multiplier unlocked.
So, what does this whole "Unlocked" mean for ATI’s latest giant
card? Well, you can't enter some secret key combination and unlock more stream
processers or ROPs, nor is there a secret to gaining extra memory. What ATI
mean by saying the model is "Unlocked" is its overclocking ability. @ TweakTown
