Sucks you couldn't overclock that far, but it has "generic memory holding things back" written all over it
This doesn't mean that 81Mhz is the "max" overclock this CPU can take, guys. 1. the generic memory 2. they didn't push it to the max in this review.
No I don't think so. If you remember cpu developement. It used to be clock speeds were determined by how many transistors you had to fire off in time. We had cpu's that did the easy stuff in 1 clock and the harder stuff in 2 cycles and the really hard stuff in 3 and 4 cycles. Then as they shrunk the easy stuff was just waste. It calculated and popped into registers way way ahead of due date. the 2 cycle stuff became 1 cycle stuff and the 3 and 4 cycle stuff became 2 cycle stuff.
GPU's have much lower clock rates because they have to do far far bigger more involved calculations before they are able to finish a Time cycle.
Since these are APU's with gpu and cpu together they are going to lower the clock bar significantly. Much of cpu's integer performance is really just wasted on consumer stuff. So it's just a design decision of dropping the clock bar and keeping with super scalar architecture to pipeline it and multiprocess it.
If you sit around in pain in misery over needing more dhrystones then it's not for you. I don't personally have any of those miseries and I think they are fairly accurately determining that most people don't.
These things will probably overclock about like a video card maybe a hair better.Edited by Hephasteus - 2/7/11 at 10:29am
