PowerMac downgrade?
I'm sure it won't end up like this, but it seems like we need to watch out for a PowerMac downgrade. I guess it depends on the chip used for the PowerMacs.
Despite all the Duo Core hype, the Intel chips we've seen so far are not as powerful as a G5, clock-for-clock, core-for-core. I've got a Rev A. Dual G5 2.0 on my desk, right next to an iMac Core Duo 1.83 (both with 1GB RAM), and, while both are fast, the G5 is more than 30% faster than the iMac for processor intensive stuff (well, the only things i've timed are H.264 and mpg4 exports from QT Pro).
So let's say the Intel PowerMacs get Conroe (last I heard, available September-close enough to August). I read somewhere that Merom is claimed to be about 20% faster than Yonah, which is what's in the iMac (although I can't find that reference anywhere). I'm not sure if that just means clock speed bumps, or the chip is just faster at the same clock speed or what. And I guess a desktop version of Merom must be even faster. Let's say another 20% (?) because there are no power constaints.
With all that, Conroe should be a bit faster than a G5, clock-for-clock, core-for-core. And if Apple sticks two Conroes in the top end PowerMac, and Conroe is available at clock speeds at or faster than 2.5 GHz, then a top of the line Conroe-PowerMac should edge out the current top of the line G5-PowerMac--on universal apps.
Hmmm.... I don't know. It seems possible that Conroe-Macs may not be faster than G5 PowerMacs. And if you use Adobe/Macromedia products, forget it, because they won't be Universal for a while.
Does anyone have insight into this? I can't believe Apple would release slower or equal PowerMacs, but maybe they've got Intel fever, and will do it whether or not it makes sense, speed-wise...
