MacWorld Magazine Benchmarks the G5s 96

Posted by pudge from the i-want-one dept.
La Temperanza writes "Macworld has released yet another set of benchmarks of the full line-up of G5 desktops, along with Dual 1.42GHz and single 1GHz G4s. The results are very interesting indeed, and I think I can safely say they're not biased in the G5's favor." I dunno, it should not come as too much of a shock that a dual G4 can beat a single G5 in many tests.

      So far it looks like the benchmarks show that the difference between a g4 and a g5 is just the clock speed difference. This seems a bit wacked so I suspect the test codes are not testing the right things.

      The obvious ways this thing should be different are huge memory moves: the true independent DDR and fast bus means this thing can move a DVD's worth of data in ten seconds. The other way this should be better is that the processor should be able to have multiple floating moint commands being processed at once (in addition to altivec). neither of these are showing up in the app-based benchmarks.

      these difference should be huge and impossible to miss. something is wrong. maybe some debug codes in the new OS or the compilers are crippling the G5.

      • The g5's memory advantage won't be a big deal in this test. Each system only has 512 MB of ram. The photoshop file is only 50 MB, so I assume a larger file would cause the difference to increase. I suspect that if the benchmarks were done on much more demanding tasks, such as multi-gigabyte renders, or a lot of muti-tasking, and giving the g5 its full amount of memory, the differences would be more pronounced.
      • Um. Multimedia processing would be exactly the kind of thing that should be faster. Like iMovie. But it's not. Dunno why.

          The "why" in this case, is actually due to the fact that most iApps are very altivec-heavy. The problem with the G5 is that its implimentation of altivec isn't as mature as the 745X series of G4 processors.


          The other thing to understand is that once the G5 becomes more mainstream, apps will be compiled for it [things like making sure both FPUs are fed, getting rid of vec_dist instructions in altivec code, etc]. As of this moment, few apps know what a G5 is, and to that end, can't run on it well.


          Also, the DV codec either doesn't use Altivec, or doesn't use the 2nd processor.. I can't remember which. I am sure this is in a TIL somewhere


          Give it time. All will be right soon enough.


          For more reading on the subject, I suggest checking out the various threads of Mac Ach. over at Ars Technica [infopop.net].


          Also, Panther shows some *serious* gains when using a G5. Expect the 10.4 to fully exploit the processor. [It has been stated by Apple that Panther/10.3 won't be "fully optimised" for the G5/64 bit]

    I have been reading all the G5 benchmarks with mixed feelings lately. First of all I should clarify that I am a fan of Macs, and so I am glad to see that there is any interest in the platform at all.

    However, I do most of my real computing on a home-grown linux cluster using Rocks [rocksclusters.org]. These intel machines are simply so cheap if you step slightly back from the bleeding edge, that I don't know if I could justify spending a significant amount on an equivilent Mac cluster (although I am watching V. Tech's apple cluster, just like everyone else apparently is...).

      Put another way, I can make a maxed out dual 1.42 G4 crawl in Photoshop. Give me a large enough hi-res, CMYK image with many layers and an art director who wants to try something new and the G4 will soon be sweating. I'm sure my ex-girlfriend the Avid editor can say the same thing with examples from her field. And, while I am neither a scientist or a programmer, I'm sure there are people in both fields who are salivating at the prospect of larger data sets and the ability to consider more complex calculations.

    For me, the major advantage of the G5 is not that it is 64 bit or that it reaches speads up to 2.0 Ghz. For me, it is that there is finally a single chip that can process at the same rate as two G4's (see benchmark results for the 1.6Ghz G5 vs 2 1.4Ghz G4s).

    This is important because there is once again - in many years - a single Apple box one may purchase and upgrade as demands increase. THAT IS as long as a single 1.6 or 1.8 Ghz G5 has the option of upgrading to a second processor (of the same clock speed of course).
