Stability

Now, it's time for the hot button issue, the one issue that Mac users use against PC users (and vice versa) all the time: stability. To put a few misconceptions to rest, I will resort to the timely bulleted list. I hope by this point, I've shown that I can definitely appreciate both a Mac and a PC platform, and thus, readers will view the following statements as pretty darn impartial:
  • OS X crashes
  • Windows XP crashes
  • My G5 machine crashes a bit less than any of my Windows XP machines
Now, let me qualify those three statements - I'll start at the bottom. Apple has it very easy. They have complete control over the hardware and drivers that go into every machine they build, they don't have to deal with multiple chipsets for a particular platform, and they don't even have to deal with multiple video card vendors. Apple controls every aspect of the hardware and software that goes into their computers. There are no strange driver or BIOS revisions out of Taiwan that don't play well with some configurations, and there are no worries about memory timings set too aggressively causing even the slightest bit of instability (without the appropriate timings, DDR400 will not boot in a G5). The PC world is much, much different; everything that Apple doesn't have to worry about or deal with, PC users may not worry about, but they definitely do have to deal with. How many times have you bought a cheaper piece of hardware from a no-name manufacturer because it fit your budget? It's not as common now because prices have gone down so much, but a few years ago, it was definitely very popular - I know. I did it. Sometimes you'd luck out, and other times, you'd have one component in your system that would always cause compatibility problems or stability issues. For me, it was an old Opti sound card; then, it was a no-name 430VX motherboard. And tracking down those kinds of problems can be very difficult because the symptoms don't always point to the culprit. I've always said that if you use the right hardware, a Windows box can be just as stable as any other machine out there - and my systems have supported that. I wouldn't reboot my system for months if it didn't have any problems. It was always a bad driver install, power outage or a program gone awry that forced a restart. People used to complain about Windows NT/2000 as a server platform because of stability; we've actually had more outages on our Linux servers than on our Windows servers. Not saying that Linux is a bad OS, but we know our Windows servers, and we know what hardware works best under them, and thus, once assembled and properly maintained, we had no real issues with them. >br?
OS X is built on a very solid core and it does handle individual applications crashing much better than Windows does. I've never had to reboot the entire system because one application crashed. It's also much better about restarting Finder (the equivalent of Explorer) if it crashes. It is things like these that make OS X a bit more "stable" of a platform than Windows, but also, remember that the tight quality control that Apple has over the components that go into their systems does also play a very large part in assuring stability.

The end result is that my Mac is a bit more stable than my PCs. It's not night and day, and the Mac does crash, just like my PCs do - it just crashes a little less frequently.

As far as hardware stability and failures go, I've heard horror stories about dead/dying G5s on Apple's support boards. I was honestly worried when I started reading through the threads; thankfully, I have yet to encounter any hardware issues with the G5, but I do recognize that there are users out there that have had serious issues with their systems. Unfortunately (or fortunately?) without much experience in this regard, there's not much I can say to Apple's hardware quality control, but I view Apple just like any other hardware vendor - there's no way that everything to come out of a company is going to be perfect. It's how they minimize the imperfections and deal with them when they occur that matter the most.

    Sorry, they updated the review with G5 2.5, dual Xeon and dual opteron. New path:

    I'm not looking for Anand to praise the Mac, I'm looking for a good article and sorry, i'm not seeing it. If Anand lauded praise on the Mac and got all the details about the machine and the OS wrong, I'd be complaining about that too.

    This is an experience piece, but as I said, I'd have appreciated it much more if would wrote it as a newbie then actually learned about it to comment out the junk.

    #27 Your explanation for why Apple is "forced" to make dual machines is laughable. It's merely a matter of MHz? The PPC 970 is shipping at 2.5 GHz while the Athlon64/Opteron is shipping at 2.4 GHz. AMD has Apple/ibm beat on memory performance but a 970 can perform more operations per clock than a *hammer core. They are both good chips.
    Not only that, Apple initally released the line with two single processor models and one dual, then they moved to two duals, then they moved all dual as they speed bumped 25%.
    The reality is more along the lines of.. the machine is designed for dual cpus so the cost of nearly doubling performance is minimal compared to a PC where you need a lower volume dual board with a potentially different chipset and dual ram banks for opterons.

    #22 You brought up an excellent point. With the release of 10.3, the official gcc tree had NO optimizations for the PPC 970. The IBM Design lead for the 970 told arstechnica that they modified gcc to optomize the G5 a bit like a Power4 and a bit like a G4 because it shared characteristics of both chips, but it was more different than just the amalgam of them.
    Current OS X software is horribly under-optomized for the G5. Our researchers have been using IBMs xlc and xlf compilers with real PPC 970 and G5 support and his code is way faster than gcc code. Initially they were seeing an average speed up of 30-40 percent but he recently told us that some code is running twice as fast.

    You didn't compare things like ... benchmarks to the speed of a PC... Granted the Mac *feals* sluggish, look at benchmarks and real-world preeformance of things like PS Filters, rendering, etc.

    http://www.barefeats.com/pentium4.html

    Also, your forgetting that Mac's come with Firewire 800, optical audio in/out, etc. PC Workstatioins don't come with this.

    As for OS Sluggishness, Many times Apple traded performance for smoothness. How often do you resize a window or minimize or whatever and theres a redraw issue on a PC... ALL THE TIME. Not so on a mac. All windows are stored in VRAM and thats where windows draw to then are compositited. On Windows, when a window needs to be redrawn because its now visble, the OS asks the app to draw, which is far less "smooth" than on a mac. Also, compare the text on a Mac to text on a PC. The text looks a LOT better on a Mac.

    Much of the greatness of using a mac is the overall feal. Anand, how does it FEAL to use a mac over a long period of time? You dont get fustrated, things dont get corrupted, you dont need to reinstall, etc. It may not be as snappy on a clean install, but a Mac's performance doesnt degrade like a Windows machine.

    Now the top of the line G5 2.5 ghz comes with the Radeon 9600 XT with 128 mb.

    And this site (barefeats) provides some informal benchmarks comparing the G5 2.0 with a dual opteron 2.0, price too.

    One thing that made me laugh a bit after reading the first part was how Anand mentioned how he was an old DOS guru but then went so far as to say that: I quote

    "Multi-tasking
    It is somewhat ironic that I would praise Apple for the multi-tasking capabilities built into OS X, given that the Mac OS trailed Windows in its support for preemptive multi-tasking.

    I remember working at Babbages when the first version of 'multitasking for DOS' came from a company called Quarterdeck the same people who develloped emm386 (extended memory manager for pc's and DOS) I think the name of it was DOS X windows or something like that. The reason that Microsoft came out with windows (which I also remember when it first came out after DOS 6.62). Was because the MAC system was Already Capable of running multiple programs at once and soon after, Microsoft Acquired Quaterdeck and Windows was borne. How could Anand forget that part of history? I am a PC user not a Mac user and even I know that MAC lead the multitasking industry.

    CindyRodriguez, thanks for elaborating on the program installs.

    Anand and thanks for the awesome review. I'm a die-hard cheap bastard. That's a non-biased die hard cheap bastard mind you. I still use a win 2k equipped Pentium 3 700. I'm sure I'll upgrade some day and this article is going to be the reason while I'll even consider making my next system a Mac.

    As for the people flaming the review out there I think you need to realize that he's taking the perspective of an independent reviewer, not the perspective of Apple's/Microsoft's marketing department. The purpose of the review wasn't to slam, or praise the system. (While you may have been hoping that's what it did, to justify your close minded view of the world) It was to give you an assessment of what it is to use a Mac from a PC users perspective. In addition to that he's writing to a MUCH savvier audience than most so he can take some liberty in pointing out certain caveats (like the fact that it took him time to adjust to the short cut keys in Mail) and understand that we're not going to look at them as black-marks against the system, but realize that's just him reporting the situation.

    If he had come out and told me how piss-poor the Mac was, or how Apple's Jobsian vision of the future is the new ray of hope in the computer industry, I would of probably completely ignored the article. But I found it to be a very candid review on the G5. That in it, and of itself makes it a very rare thing on the web these days. Andandtech.com, theiquirer.net and arstechnica.com seem to be part of a dwindling few places you can get good factual (not opinion based) reporting now-a-days. and I appreciate it.

    Again thanks for the review, it was extremely helpful.

    The 9600 shipped with the G5's are not full fledged PRO's per ATI specification. They are underclocked to just over 350 MHZ core plus they offer only half what the PC version offers in terms of VRAM. Keeping in mind that the non-pro PC versions of 9600 are clocked around 325, with at least 128 MB of ram, the 9600 shipped with the G5's are somewhere between a pro and a regular version.

    My god, almost all of these replies are angry, frusterated, or just totally objective mac users.

    #20 - Again, what? I didn't say anything about comparing architectures. You we're arguing that PPC based workstations maintain a similar price to performance ratio for x86 workstations. That's not even close to being true. I am sure that some people do use Xeon's and Opterons for workstations, but in my experience those tend to be pretty high end and are typically used for servers such as those that powers Anandtech. It seems to me that Apple uses dual CPUs for their workstations more out of necessity to keep performance up due to an inability on the part of IBM to ramp up clock speed. Don't get me wrong, I'm a big fan of the Power PC architecture, but your equivalent price to performance argument of the two platforms is flawed.

    I enjoyed the article, although I think Anand has just scratched the surface in terms of cool apps available for Panther. Also, I'm running a 1.33 ghz G4 tower with 1.5 gig ram and don't find Office 2004 to be slugish at all....keeping in mund that 60% of my work day is spent on a WinXP box. As others will remark, the current lack of malware on the Mac platform is a real differentiator that saves me time and money, and like many of you, my time is pretty valuable. I hope Anand will continue to explore the OSX experience and share his findings...it's great to have viable alternatives to what comes from Redmond.
