PC World: Apple G5 Gets Trounced By Athlon 64 1063

StewedSquirrel writes "PC World magazine has published an article comparing the AMD Athlon 64 and Opteron versus Apple's G5 processor, both 64-bit contenders for the title of 'fastest desktop processor.' Apple has made many claims to be the first, fastest and only 64-bit processor for the desktop and workstation market, but (not mentioning the fact that Opteron beat the G5 to market by over 4 months) the benchmarks should speak for themselves. Of note is the 3.2GHz Pentium 4, coming in competitive with the G5, but significantly behind the Opteron and Athlon 64 systems."

      The Opteron 140 and 240 series are workstation-class chips. Put an Opteron or two in a box with a bunch of hard drives--it's a server; put it in a box with a $1,000 graphics card--it's a workstation.

      Correct me if I'm wrong, but don't they have dual processor workstations? IIRC, the Athlon 64 doesn't do SMP (excluding the FX51, which is just a rebranded Opteron).

      So therefore, to have a dual processor AMD64 workstation, you'd need an Opteron. Case closed.
    • The G5 is a server/minicomputer class chip. IBM has been using them for high-end machines. The only difference with Apple's version is the packaging.

      That said, the important thing to compare is the relative price of the systems. There have been several cases where various Mac-oriented magazines have trumpeted "Mac beats PC", but in the performance tests they have tested the Mac against a PC costing less than half of its value. That said, this test is actually pretty good. From a quick search, the Alien

    From the article:

    "But upgrading to XP 64 could mean giving up functionality without getting much in return. In fact, XP 64 looks like a throwback to Windows past: Its interface mirrors that of Windows 2000 or even Win 98. Microsoft has not disclosed what else will be in the OS, so it is possible that you'll still get most of XP's other features.

    XP 64 won't have the 32-bit XP's support for DOS apps at all, nor will it run 16-bit apps (but it should have no trouble with 32-bit software). More important, 64-bit drivers for common hardware, such as printers, will be scarce when the OS debuts."

    In moving from a Dual 1GHz G4 (Quicksilver 2002) to a Dual 2GHz G5, I have yet to find any software incompatibilities - everything works just fine.

    This may change once my copy of Panther shows up, but my printer and other hardware continue to work for now.

      You also are not running in 64-bit mode. The Macs do not take advantage of their 64-bit nature like XP64.
    • The beta 1 seemed to run legacy stuff just fine.

      Sating that XP64 is a 'throwback' when the only version available is the first beta that doesn't have any useful device drivers, doesn't run directx or even .net is a bit premature... Wait until a version is released that's more than a 'hey look we've got a 64bit OS too, honest!' release.

      Anyway the first thing anyone does when they install XP is switch off all the crappy eye candy and go back to the Win2000 'throwback' look because that was actually useful.

    It might still get owned, but redoing the tests with the OS that the G5 was meant to run on will be a better comparison. What can it hurt, it's only 9 days away from release.

      I just sent this letter in to PC World. I think it pretty much covers all the mistakes they made in the cross-platform benchmarks.


      I have been a long time reader of PC World, and have much respect for your magazine. However, I am yet to see a more abject review than the "64-Bit Takes Off" what was presented in your November 2003 Edition.

      Let's start with the choice of Microsoft Word. Undoubtedly a widely used piece of software, and Microsoft incredibly allowed Office v.X for the Mac to receive a number of features that the Windows version is yet to receive. There is, however, one thing that Microsoft will not allow Office for the Mac to achieve; and that is performance parity. To add to this, much of the codebase of Office v.X is left over from the good ol' days of MacOS 9 - reflected in the fact that Office is still a Carbon app. So, although Office on the Mac is extremely widely used, it's of dubious use as a means of comparing performance between processors. Unless, of course, all you do is Office and it's not presently running fast enough for you.

      Next. Premiere. This is what stunned me. There is a reason that Premiere doesn't work very well on the Mac. This is because absolutely nobody who does video editing on a Mac uses it. Period. Final Cut Pro wipes to floor with it; not only in functionality, but performance also. Of all the ways you chose to benchmark the G5s, this surprised me the most.

      In the Quake test, the Mac was hamstrung by the fact that it only had a 128MB video card in it. I also may be wrong in making the assertion, but doesn't the 256MB ATI 9800 Pro run at a faster clock rate than its 128MB cousin? This would account for quite a performance differential. Despite the fact that Macs aren't really known for games, no other computer with a 128MB graphics card beat it.

      The next test was Photoshop. This is the one app you benchmarked in which some 64-bit optimisations have taken place for the Mac, and is also an app that many people use on the Apple platform. In this test, the G5 beat everything on offer from the x86 world by quite a handy margin.

      What makes this even more impressive is that the G5 system you benchmarked is running on a stop-gap operating system release from Apple. OS X 10.3, codename Panther, has been specifically designed to take advantage of the G5's 64-bit CPU structure; it's out in barely a week.

      I would certainly be interested to see a re-run of the tests, if you think that this feedback is valid. Cross-platform benchmarks are notorious for being difficult to standardise; I do, however, believe that if done properly they can be both useful and interesting.

    So they compare 32-bit apps running on a 64-bit AMD chip to 32-bit apps running on a 64-bit G5 and conclude that the AMD chip is much faster than the G5.

    This does nothing to benchmark the capabilities of the chips -- just the capability of the chips to run non-native apps.

    Go back to your lives, citizens, nothing to see here...
    • They run nativ apps. Both processors can process 32bit code natively, and they do it here.

      And AMD should profit MUCH more from 64 bit than g5:

      So I followed their links to the other PC sites and configured a few of them to match (as closely as possible) the basic dual G5 from Apple. Result: Apple, $2999. AlienWare: $3160. Voodoo PC: $3060. Falcon Northwest: $3179. Etc. I'd have done them all, but I have a life.

      I tried to be as fair as possible. However, it was usually difficult or impossible to get matching optical drives (as in SuperDrive), and many models not only didn't offer Gigabit ethernet, they didn't offer Ethernet *at all.* They had modems, though. Optional (I didn't add them, so they'd cost you extra.) Good grief.

      So lacking some of the features that the G5 comes with standard, the Athlon-based PCs came in more expensive. Same old game on the "PCs are cheaper" front. The Athlons may be faster, but they'll cost you.

      Now how is that for fair? "Faster costs more money." That sounds like reason to me. You can have a really fast processor, but at the expense of giving up a few things you might want in order to be productive. Like the internet.

I think it's going to come down to what you like best. Personally, I like OSX better than Windows or Linux on the desktop. OSX gives me all the power and stability of Linux, and it's easier to use and prettier than Windows, and it runs Photoshop. I'm a photographer, so that's pretty important to me.

    I cannot believe this is taken seriously on Slashdot.

    Let's look into this more closely: the PCWorld team tested only four applications, one being Microsoft Word, FFS, and another being Premiere, which is no more supported on the Mac, runs in Classic and is leagues behind Final Cut Pro in terms of performance, as anyone with a clue in Mac video processing will tell you. This alone qualifies this comparison as biased in my book.

    Where is the After Effects test ? And where is the Mathematica test ? Did you only know that any G5 will trounce an Athlon 64 in these apps ?

    Also, looking at the results, I can hardly call it "trouncing the Mac". Only one in the four apps make use of the 2GHz' second CPU (Photoshop), and dutifully the G5 beats the PC in this test, and the scores in the other tests (not counting the Premiere's joke of an application) are not even that far apart.

    I've argued with benchmarkers over and over about this, Premiere is a lousy benchmark, used only by people who want to stack the deck against Macs. Premiere is highly optimized for PCs, and highly unoptimized against Macs. Fortunately that benchmark will go away soon since there won't BE any further Mac Premiere versions.
    If you want to do a proper test, you'd use a crossplatform product that runs equally well on both platforms and is highly optimized for dual processors, like Discreet Cleaner or Combustion.
    There's only one benchmark I can think of that is more worthless than Premiere, the "MSWord scroll test." For some stupid reason, some benchmarkers think it's a useful test to see how fast the can scroll to the end of a long Word document with the arrow key. Unfortunately, Word has a delay loop built into the scroll function, it even changes the delay loop depending on the speed of the CPU. The results are totally useless.

    So this is how we benchmark two different platforms these days?

    For everyone's information, I should not have to point the following out, but here we go... the benchmarks were taken from the following apps -

    Quake III, developed on, and for, x86 over 5 year period of programming research and enhancement. Later ported to OSX in a week by OmniGroup.

    Word, developed on, and for, x86, by the developer who also wrote the operating system running on the PC's. Ported by MBU to OSX.

    Photoshop, Adobe develops Photoshop in a very balanced way for the two platforms, and these are the results for this test -

    Fastest 50MB image = 17 seconds, G5 = 18 seconds
    Fastest 150 MB image = 47 seconds, G5 = 51 seconds

    The final test was a Premiere rendering, where almost all the systems tested did the job in 3 or 4 seconds. The fastest was 3 seconds, the G5 did it in 4. This is Premiere which no longer exists as a current ongoing product for OSX.

    "Real-world" app tests like this one are better, but only if the apps used are representative of apps used by the person reading the benchmark. They are not a realistic measure of holistic system performance.

    Adobe Premiere? Come on! Does anyone on the Mac use that at all anymore? Is it even OSX native? Since Final Cut 1.0 came out 2+ years ago, anyone who considered that dog Premiere deserves what they get. Isn't there a better editing package on the PC, or is the Mac just that much better for video editing?

    Microsoft products should be excluded from benchmarks on Microsoft's OS. Of COURSE Microsoft optimizes performance of their apps on their OS more than their apps on other OSs. That test is pointless.

    The Quake test would be valid, except as many people here have pointed out, it's a 32-bit app, so it's not using any of the 64-bit capabilities of these boxes. When we get a native, 64-bit version and can compare it to two boxes with the same ATI video card, then it will be a valid test.

    I am seriously considering getting a G5 just to run Matlab simulations. Where's the tests of something that may stress the hardware a bit, like Mathematica or Matlab?

    These benchmarks are a bad joke. My pentium II or Athlon box runs Word pretty fast.

    This could be made more clear in the Slashdot header...I'm sure it's possible to build a system out of old 486s that could put both of these to shame for load times.

    Their tests are largely I/O-bound and video card related, too. It's a system comparison, not a processor comparison. If you have different I/O or video card, you'll get different results.

    So who has the faster processor? Who knows. I suggest you buy the system you like the most.

    I had a chance to try a 3.2 GHz P4, an Opteron, a dual G5, a 3.06 GHz dual Xeon, and an Athlon 64, using a suite of productivity and multimedia apps. Here's the verdict:

    The P4: Very very fast.
    Opteron: Super fast.
    Dual G5: Really really fast.
    Athlon 64: Totally fast.
    Dual Xeon: Nice 'n fast.

    Telling results! Unfortunately since I have put so much effort into accurate, impartial analysis of the test results, and participating in all the arguments with disbelievers and naysayers, I have not had a chance to get any work done for months. But who wants to use CPUs for productive tasks anyway, when it is so much fun to sit back and watch them "trounce" each other!

    There seem to be lots of complaints about the fairness of the benchmarks.

    If you want to compare the performance of CPUs with different ISAs, then you need to have the benchmark source code to compile it to the target ISA. This also brings the performance of the compiler into question but there's just no other way to do it if you want to compare CPUs with different ISAs.

    One benchmark that people in the industry use to measure relative CPU performance across different ISAs is the SPEC benchmark. Just about every single computer maker from Dell to HP to Sun have submitted scores. Apple has not. This is in an of itself very telling. What is Apple afraid of? I'm hoping IBM releases a computer based on the G5 so that we can get some idea of the SPEC performance. Apple seems to believe it has something to lose by submitting a SPEC score.

    Don't like SPEC? Please suggest some other CPU intensive applications to benchmark that have source code and publish your results.

I'd rather just believe that it's done by little elves running around.
