Intel Developer Macs Outperform G5s

bonch writes "Developers working with the new Intel-based, developer-only Macs are impressed with the performance. The machines take as little as 10 seconds to boot from Apple logo to desktop, and apparently run Windows XP at 'blazing speeds.' Rosetta tests demonstrate the PowerPC-native build of Firefox running just as fast as it does on a high-end G5."

    The developer version of OS X can run on non-apple hardware, but only if you think troubleshooting is fun (read: not well). The versions that will reach consumers on Intel systems will be DRM'ed to prevent this. It will be crackable, but the 1% of the population that can do this isn't Apple's target market anyways.

    Sometimes I have the need to develop on Mac environment for compatibility requirements, but I don't really want to buy a Mac just for that. For example I don't buy a TUX machine to run Linux.

    You would if it was important enough to you. I bought mine so that I could support Apple users. i.e. I saw a very real use for the machine. (Best purchase I ever made, BTW.) With Linux, there's just too much noise and not enough signal to make anyone want to purchase a Linux-built Desktop machine.

    Yes, the other factors are that the dev kits don't support any kind of special features. It's standard PC BIOS so it doesn't have to bother to search any of the many other places/buses a standard mac can boot from.

    Also, since plugins cannot be emulated, there is no way for anyone to install kernel extensions that slow down the boot times of OS X.

    In other words, the speed these people think they're seeing are actually do to a horrific lack of features.

  5. Integer vs. Altivec by WatertonMan · · Score: 4, Interesting

    I think most of us expected the P4 to perform better for Integer like code on applications that don't effectively SMP. So that's not that surprising. I am surprised at the speed of Rosetta, although that will be a mixed bag once again depending upon the application.

    What I'm really interested in is speed on stuff that really leveraged Altivec, like A/V programs. I'm curious about Quicktime 7 for instance. Now some of these programs can use some similar functions on the P4. But from what the Altivec folks were telling me some code ought differ by as much as 50%. (i.e. the PPC is twice as fast) A nice simple test is to compare programs like iMovie on both platforms.

      The altivec implementation on G5s is weak compared to that on G4s, so the advantage isn't as great.

    Actually, Apple makes money selling iPods!

    But seriously, I hate the "Apple makes money selling machines, not software" myth. Apple also makes a killing on software, and there's higher margins than hardware. Steve Jobs said Tiger had already sold a million boxed copies of Tiger at the WWDC. Multiply by $129? That's a lot of cash coming from just the OS. And don't forget about their stance in the professional media market. How much is Final Cut Pro selling for these days? What does Motion cost?

    This just means that the G5 crap being better performing than the Intel stuff was pure marketing BS

    Maybe G5s are not so fast. But:

    "It's fast," said one developer source of Mac OS X running on Intel's Pentium processors. "Faster than [Mac OS X] on my Dual 2GHz Power Mac G5."

    So, uh, a 3.6 Ghz P4 is faster than two 2 Ghz G5 - 4 Ghz? - SMP, but 4 Ghz.

    Sorry, I don't buy that. Even more if you take into account that Intel isn't exactly the performance/Hz leader - in fact it's the worst performer these days, Opteron and PM beats the sh*t out of that P4 at much lower speeds from what I've read.

    There're lots of factors that can change things - freebsd algorithms, are, for one, optimized for i386 variants. Also, Mac OS X is compiled with -Os - optimized for size, no for speed. (Paranoic mode on=Hey, maybe this switch was planned and it's not a coincidence)

    And then there's the Placebo effect. IOW: Show me numbers, don't tell me "it's fast", I don't trust you. In Linus' words: "If we can't measure it, it doesn't exists". Unless someone writes a decent comparative, I'll take this article as Apple Marketing - Apple has been very critized for this change, I wouldn't be suprised that Apple is interested in articles like that, showing how good move has been the switch to intel

    So why are we still forced to sit through full boot cycles?

    Apple has really been pushing people to Sleep the machines instead of turning them off. Sleep mode uses a very tiny amount of power, and you get your instantaneous boot (with apps open and windows positioned...). I have been doing this with my Macs since OS X appeared and let me tell you it is the only way to go. Especially on laptops. In fact I am still using a CRT on my G5 and the computer 'boots' faster than the monitor (warm up).

    There is no way for the system to 'detect a change'. There is not magic signal that the motherboard produces if a PCI card is inserted. In fact, for consumer level motherboards, inserting a PCI device while the system is powered will fry your system since they are not HOT swappable/insertable.

    Your point makes sense though about making some sort of assumed last known configuration the default. This would require the user to hit a button if they change their config so a full reboot with full PCI scan could ocurr - probably not too user friendly.

    Note that this is really a weakest-link situation: If trippling the disk speed halfed the boot time, it means the disk was actually the major stopper in the *original* setup; however, once you have a very fast disk, further disk speed improvements won't change much. Other factors will become more important now.

    When I upgraded my old 1.7 GB disk to a 13 GB one, bootup got *lots* faster. However, now the CPU was the major stopper, and upgrading from Pentium 166 to Celeron 400 again resulted in a considerable speedup. Upgrading to a 40 GB afterwards disk didn't change that much -- the processor is still the slowest part in the system. After another CPU upgrade it would be different again, of course...

  12. Rosetta only translates G3 code, not G4/G5 by green+pizza · · Score: 3, Interesting

    The biggest gotcha with Rosetta is that it will not translate opcodes for G4 or G5 processors. There are already some applications for Mac OS X that require a G4 processor.... these *will not* run via Rosetta and will require an x86 recompile to run under the new Mactel machines.

    As someone that's built thousands of Windows machines over the past few years, let me be the first to say this: Out of the box, on current hardware, Windows XP is blazing fast. What slows it down is all the bloatware and DLLs that you load up as you install software.

    Take XP, load Office 2003, Norton AV, the standard CD burning and DVD viewing apps, and watch the performance (and boot times) degrade considerably.

    Many people in the Windows world seem convinced that a major cause of a slow machine is "I've got a lot of things installed on it".

    Now those of is in the here see that as nonsense, since filling up the hard drive with not-currently-executing code does not have any impact on memory usage or CPU usage.

    However, a lot of Windows programs have this tendency to install things that "always run in the background", and that does eat memory and impact CPU load. Back in the day when I actually used Windows a lot (and when RAM was still expensive), it was commonplace for people like us to spend the time digging through the Start Menu and the Registry to disable all those little side-processes.

    As a result, people like me had machines that were MUCH faster and more responsive than most normal people with their storebought machines with specs usually much better than mine on-paper.

    I suspect the same may be true today, between store pre-loaded crap and resident bits of installed software, even if cheap RAM has averted some of the issue.
