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 POINT is that Apple never marketed the G5 as the fastest workstation. All Apple marketed the G5 as was the a) first 64-bit desktop (and if your definition of desktop differs from "a pre-built box from a well-known company that an ordinary human might buy", that's your problem, not Apple's), and b) the fastest desktop around at the time.
Saying, "Ooh! Ooh! New computers have come out! There are benchmarks against computers Apple wasn't talking about! The G5's not the fastest! Apple LIED!" is just plain dumb. Of course faster computers will come out! Apple isn't dumb enough to think or claim that their first-generation G5s will always be the fastest, and anyone who thinks they were claiming that is dumb.
And does anyone else see the possible conflict of interest with PC World running these benchmarks? Now, note that I'm an Apple fan. However, I won't completely believe any benchmarks that are done by anyone with an interest in seeing either side win. And it would probably be best if both computers were running something neutral, like a Linux or a BSD. Does anyone really believe these benchmarks are any more fair and unbiased than Apple's own???

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.

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.

This alone qualifies this comparison as biased in my book.

Also, looking at the results, I can hardly call it "trouncing the Mac".

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.

When reading my analysis, bear in mind that an average person with a stopwatch has +/- 1 second margin of error per test, so anything within two seconds is considered the same time.
Also consider that most machines spin down their hard drives when not in use, leading to up to a five second stall. Because there was no aggregation of multiple tests, tossing out any outliers in the process, these test results are basically useless, but you can consider them to have a +/- 12 second margin of error.
Finally, bear in mind that my analysis is extremely biased. Please look at the facts yourself and make your own decisions. Do not blindly accept my opinion as truth, as doing so doesn't do anyone any good.
Analysis of results:
- Render test: all times identical.
- Quicktime test:invalid (see below).
- Photoshop 50 MB test: tie between Polywell 2 and dual G5 for first place
- Photoshop 150 MB test: tie between Polywell 2 and dual G5.
- Quake tests: invalid.
- MS Word tests: invalid.
Reasons for invalidation of Quicktime test:- If two machines with similar performance suddenly show more than a factor of two difference, this almost always means that only one processor is being used on the slower system due to differences in the software used.
- The test is poorly described so that it cannot be reproduced. There is no "Quicktime format". Quicktime is a wrapper movie for any of dozens of formats. QuickTime has different default codecs in different versions. I doubt Premiere installs the same version of QuickTime that most Mac OS X 10.2 users would have installed (thanks to Software Update), thus there is a good chance they were using different codecs in this test.
- According to the QuickTime API docs, your application has to be modified to take full advantage of multiple processors when compressing images. Since Premiere for the Mac was last updated not long after that support was added in QuicktTime (as best I can tell), odds are very good that it does not use the new APIs, while recent Windows versions almost certainly do.
Reasons for invalidation of MS Word test: factor of four difference clearly indicates that software is not comparable across the two platforms. The results are beyond any sane person's ability to accept from nearly equivalent machines running even remotely similar code.Reason for Quake test invalidation: this should be dependent on graphics card performance, not CPU performance. The G5 beat all but one configuration with an equivalent video card. This one configuration inexplicably was about 50% faster than all the other configurations. Since at least one machine in each 128M speed class uses 8x AGP, it is safe to assume that there are substantially different versions of ATI's drivers being used in these tests, rendering any results meaningless in terms of the performance of the machine itself. The most likely (but hard to prove) interpretation of these results is that the G5 performs slightly better than any Athlon64 when given an equivalent video card, and that the one machine is either mislabeled or has a newer version of the ATI drivers than the G5 and the other 128MB PCs.
But that's just my opinion. I could be wrong.
