ATI HD4800 GPU/MEM clock performance scaling

[Helmore]

Latency. But we don't game at 500MHz GDDR5, do we?

Can it even go that low on all boards? 2000 MHz. effective is a 1000 MHz. data clock...
Although you were probably referring to the command clock, which is half of the data clock.

Yes. The value you can change in CCC, AMD GPU Clock Tool etc. is the command clock, so that's what the review is refering to.
