iLife '06 Performance with iPhoto, iMovie HD and iDVD

One of the benefits of OS X and Apple's application suites is that most of the applications are already properly threaded. Even though you wouldn't expect it, iPhoto is threaded quite well and thus our import photos test gets a speedup from going to quad cores.

The test is simple; we timed the import of 379 photos into iPhoto which, believe it or not, is quite CPU intensive and not as I/O bound as you'd think. After we got the time we divided it into 379 to get the number of pictures imported per second. We included the performance of a hypothetical dual core Mac Pro in addition to the native quad offerings in order to provide a good point of comparison to the dual processor PowerMac G5s.

iPhoto 6.0 - Picture Import

Although there's a slight performance boost when going from dual to quad core (6.9%), this test is largely dependent on clock speed within a single microprocessor architecture. Comparing the Woodcrest based Xeons to the older G5s is no contest, at 2.0GHz the Mac Pro is already 14% faster than the 2.5GHz PowerMac G5; even if we account for the dual vs. quad core comparison, the 2.0GHz Mac Pro is still noticeably faster than the G5.

The next application we looked at was iMovie HD. There are two primary focuses for performance in iMovie HD, video import speed (if you are dealing with a non-DV or non-iSight video source) and effect rendering speed. We focused on the latter, measuring the time it takes to render the most CPU intensive transition and video effect in iMovie HD.

iMovie HD - Add Billow Transition

Our Macs have gotten a little too fast for the billow transition test, as the Mac Pro 2.66GHz can now complete the test in 3 seconds flat. All of the Mac Pros here are faster than the PowerMac G5s, which is what we'd expect given what we learned in the iMac Core Duo vs. iMac G5 article.

iMovie HD - Add Electricity Video FX

Rendering the "Electricity" Video FX sees no benefit going from dual to quad cores, but the Mac Pro doesn't need it as the 2.0GHz configuration is already 26.5% faster than the PowerMac G5 2.5GHz.

Finally we've got iDVD, an application that you can use to create DVDs that are playable on any consumer DVD player. There are once again two aspects to performance in iDVD, video encoding performance and menu encoding performance. Since we've already looked at video encoding performance with Quicktime, this test is predominantly limited by how long it takes to encode the menu system in our test DVD. There is a small 13 second iSight video and audio that's encoded in the process but it adds a matter of seconds to the overall time. The image is written to disc instead of sent to the DVD burner for obvious reasons. The results are expressed in seconds, lower being better. This workload is multithreaded.

iDVD - DVD Image Creation

The benchmark gets just under 11% thanks to the 4 cores in the Mac Pro, but even without them the Mac Pro 2.66GHz is able to outperform the PowerMac G5 2.5GHz by just under 13%. The Xeon seems to scale much better with clock speed in this test than the G5.

    Let me tell you! I just got a the two 2.8ghz Quad core Macpro and this baby is like driving greased lightning. Plus it is a lot quiter than the quad g5 that I had (and basically blew up becuase it couldn't take my working with it.)

    These second generation MacPros are a great investment (just make sure you get the 3 year Apple Care warranty - Just in case)

    Terrabit has a http://www.macprojournal.com/xp.html">site detailing how to "slipstream" Intel drivers for the Mac Pro's SATA hard drive controller and speed it up from under 4MB/s to 60 MB/s!

    I posted a bunch of screen shots to help those not familiar with Windows "slipstreaming" at http://st118.startlogic.com/~macproxp/index.html">my site.

    Help get the word out!

    Anand, where is the final installment?!?

    I am trying to decide if I should buy this computer, and am trying to be patient in waiting for your review, but c'mon... I have to decide soon.

    P.S. I enjoyed the other parts for their very in depth look at this computer.

    Thanks

    Yes, Anand has done a first-rate review of the Mac Pro. I think he's waiting for Apple to release a new beta of Bootcamp before finishing the next installment that will cover running Microsoft Windows on this machine.

    But if you're anxious, based on everything that has already been said by Anand and on many other sites, I don't think you would go wrong with ordering your Mac Pro now. Apple is aware of that SATA issue (under MS Windows. It will likely be addressed by the next Bootcamp release. Parallels is another option in the meantime. (When OS X 10.5 is released, we may not even need Bootcamp or Parallels as separate installs.)

    As for me, I'll order the Mac Pro from Amazon.com because of their $150 rebate.

    I am going to lease it from apple, it's a really good deal, if you have a business.
  • maharajah - Thursday, August 24, 2006 - link

    Anand, do you have any specs on the MacPro intake and output fans? Any model numbers, current or power ratings? Is it a 3 or 4 wire connector, or is there a custom connector on the fan housing? Can the 120mm (I assume it's 120mm) fans be replaced easily? The reason I am asking is that while the OEM fans are quiet at idle (based on the reviews), I have fans in another PC that are almost silent (<20dB from 1 foot away) at idle and load. I was thinking of replacing the MacPro's fans with these once I get the machine. Thanks.

    >G5s kept up well with Intel and AMD, and were often faster - sometimes much faster - but weren't going anywhere in the foreseeable future<

    IBM uses a similiar architecture as the G5 in the multi million dollar iSeries, and Microsoft uses a G5 clone in their Xbox 360, so the G5 architecture was hardly dead. If anything, I've heard IBM refused to lower prices on their processors to suite Apple because Apple represented so little profit.Your reply dictates the myopic view of Apple users that the G5 processors was exclusive to Apple, and IBM actually cared when you jumped to Intel.

    Also, the G5 architecture has been getting it's butt kicked by AMD 64 for quite awhile, while only Altivec optimized apps on G5 really pull away. Gee, you lost Altivec on the Intel platforms, and you're froced to use Rosetta, but you're still raving about the Intel platforms. Doesn't say much about the G5 by your own admission.


    >I don't know whether you're an AMD or Intel fanboi<

    Neither. I use the best tool for the job, not the specific hardware a single vendor tells me to use or allows me to use like Apple does. I've migrated Windows servers from dual P3 Tualatins to dual Xeons, and then to Opterons. I'll likely switch to Woodcrest while getting the price from a vendor of my choosing, not who makes my operating system.

    >A computer is just a tool to get things done

    Then why are your Apple buddies raving about crap like how 'pretty' the Mac Pro is, and the layout of rear ports? You honestly to god think anybody with a legitimate IT job cares about that? Computers belong under the desk or in a server rack, not displayed on a desk like over proced stereo equipment.

    >Hmm, have you heard about the best tool for the job?<

    I've used dual processor G5s, and respect the way Apple has polished multimedia workflows on OSX with better productivity than Windows. Other than that, I could care less because because the world doesn't revolve around Photoshop, page layouts, and video editing.

    >I would immediately insist on using XServes just because they're from Apple.<

    Explains why you don't make buying decisions for your company. I've seen benchmarks of XServes getting humiliated by NT4 and Win2K in SQL benchmarks, but if I were rendering crystal balls in a server farm it would be my first choice {smirk}. Also, if the G5 based XServe is so great, why is Apple themselves procaliming the Intel based Mac Pro as significantly faster than the G5? Oops...guess you should visit Apple.com more often, are are you smarter than the server engineers in your Company because you know how to use OSX?

    >Cool, e-Machines are going to be producing 8-CPU Xeon-powered workstations for $1250?<

    A single, 3ghz Core 2 Duo will beat a 2.66ghz dual processor Woodcrest in about any application you hand it other than those very few that can utilize four cores. It won't take E-machine an HP long to start producing sub $1,000 workstations with the faster Core 2 Duo processors in them, and those systems will be faster than the 2.66ghz Mac Pro. Sorry for that reality check, but you are now in the Intel PC industry and have to learn to deal with it. Apple won't be able to make up benchmarks showing the superiority of their platforms because unlike the G4 and G5, the same architecture will be running Windows and Linux.

    >Or maybe Apple might upgrade their offerings ... they've been known to do that occasionally<

    As I said above, a 3ghz Core 2 Duo will spank a dual processor 2.66ghz Woodcrest for about 90% of the tasks you can do on a desktop. Apple could make such a system for $1250 in their iMac line 6 months down the road, but you honestly think Apple will do this and humilihate their flagship Woodcrest owners? They haven't in the past, so the ones getting screwed in the long run are Apple owners and not those of us who can pick and choose our hardware. You can then explain the logic that one to your kids when they are competing in the job market with $80,000 in college loans, but how they should only buy one product from one vendor.

    Wow, what a prick you are. Look back at my post to see what this asshole is replying to. Here's exactly what I said, full quote (I've added bold to "doesn't"):

    The fact that I actually enjoy doing my work with OS X, and find myself being more productive with desktop applications, doesn't mean that if I were making the buying decisions for my company, I would immediately insist on using XServes just because they're from Apple.


    Massaging other people's posts just makes your own arguments even weaker.

    Gosh, Spike ... lots of rage there. Why such a fierce assault on a computer that wears a happy face? ;<)

    I don't doubt that a 3gHz Core 2 Duo six months from now will outperform today's Mac Pro, but in the computer world there is always something "around the corner" that will be better/faster/less expensive. Most of us buy computers to suit today's needs, not next year's. The new Mac Pro is a great performer and a good value, regardless of whether you use it for Microsoft Windows or OS X.

    As for Apple's servers, even their outgoing G5-based XServe has sold well to big customers. Credit card processor XTech, for instance, uses a gazillion of them. NASA has an enormous XServe installation, too.

    Before I accuse you guys of thinking like Tom's Hardware, why don't you do us a favor and compare the Mac Pro to a single processor Core 2 Duo at the same clock? Then compare the $2500 Mac Pro to a Single Core 2 Duo running at 3ghz, and see what's faster.

    Gee, that 2.66ghz Core Duo system would be a LOT cheaper cheaper to build and likely perform virtually identically to the quad core Woodcrest, except for like maybe two apps that have some concept of multi-threading. The 3ghz dual core system would beat the Quad core Woodcrest at 2.66 in all but maybe one real world benchmark.

    When E-machine and HP are selling $799 machines 6months to a year from now that spank the Mac Pro, what say you?
