“While it’s easy to argue that Apple had always planned to have Intel based Macs out as soon as Intel launched Core Duo, it’s really tough to say that the transition is ahead of schedule if major software support isn’t there (even some of Apple’s own applications won’t get support until March). These first generation of Intel based Macs are more like public beta tests rather than final platforms; while the hardware may be complete, as you will soon see, relying on binary translation to run any non-Universal applications isn’t the most pleasant thing in the world. However, Apple isn’t forcing the new platforms on their customers, as you still have the choice to purchase the PowerPC G4/G5 based systems at the same price if you desire,” Anand Lal Shimpi writes for AnandTech. “The new Intel based Macs are selling though, despite the early stage of the transition. And they are selling to who you would expect them to, the early adopters, the Mac enthusiasts, those who need a computer today and won’t upgrade for a very long time, oh and of course, some may find their way into my hands.”
“When Apple released the Mac mini I looked at it and thought they had struck gold; they basically took a notebook platform, massaged the shape, and stuck it in a wonderful form factor for the casual desktop user. In the process you lose the ease of internal access that larger form factors would offer, but the end result is very close to the perfect form factor for casual users. With the iMac, Apple has pretty much done the same thing; they’ve taken a notebook motherboard and processor, although this time combined it with a 3.5″ desktop hard drive, and mounted it behind a LCD panel – creating a very elegant desktop computer,” Lal Shimpi writes. “Apple has done the bare minimum and outfitted these two systems with 512MB of memory. I mention that 512MB is the bare minimum because it honestly is for OS X, but I will mention that one of the first upgrades I would perform on these machines is to bring them up to 1GB of memory. With only 512MB there were a number of cases during my normal use of the machines (which in this case didn’t include any heavy multitasking), that I found them swapping to disk. Just browsing the web or checking email didn’t trigger it, but it was once I started to really use any of the iLife ’06 or iWork ’06 applications that 512MB quickly became a burden.”
“One thing I encountered when running some of the benchmarks for this article was that the Intel based iMac used more memory than the PowerPC based iMac G5. Each application ends up taking up another 1 or 2MB on average on the Intel side, but it does add up,” Lal Shimpi writes. “For example, just after boot while sitting at the desktop there was a difference of 15MB between how much memory the iMac G5 and the Intel based iMac had in use. If you do end up with an Intel Mac, it is yet another reason to opt for more memory than the default 512MB.”
“At the heart of today’s comparison are two processors, Intel’s Core Duo and IBM’s PowerPC 970FX, otherwise known as the G5,” Lal Shimpi writes. “The first comparison is system power consumption at idle, this is with both identically configured systems being freshly booted and sitting on the desktop with no disk accesses or anything. Note that the systems weren’t left alone long enough for the hard drive to spin down yet. The Intel based iMac consumes about 2/3 of the power of the iMac G5, impressive and pretty much expected given what we’ve seen of the Core Duo in the past. The G5 is a solid competitor here, but the Core Duo is in a completely different league of power consumption. Under load, the difference in power consumption is just as pronounced – with the iMac G5 coming in at 96W while the Intel based iMac is at 62W. Once again, we are looking at approximately 2/3 the system level power consumption from the Intel based iMac.”
“If you find yourself running applications that are all Universal today, then the new iMac is a wonderful solution, however anything that requires Rosetta to run is going to hurt. If you absolutely have to buy a machine today and it absolutely had to be an iMac, the early adopter in me would still recommend the Intel based offering, but it would be full of painful times as you wait for application support,” Lal Shimpi writes. “While I don’t view Rosetta as a real option if you plan on getting any work done with an application, it is a way to ensure a very seamless transition between platforms. It is largely because of Apple’s self sufficiency and their small size that they could undertake such a large transition and succeed so very well at it, but regardless of the reasons, the end results are positive.”
