Intel iMac Core Duo (and other Macs) Subversion benchmark numbers

So Steve Jobs says that the new Intel iMacs are twice as fast as the old iMacs. So Gus happened upon a programmer-relevant benchmark: Subversion compile. For the non-nerdy among us, Subversion is a place where programmers put their code so that it stays safe and they can go back or compare with old versions.

Here’s all the numbers I’ve received so far:

iBook G4 1.2Ghz 768MB (after reboot) - 11:49 (Cameron)

PowerBook G4 800mhz 768MB - 11:34 (Steve)

PowerBook G4 1.33Ghz 1.5GB (that’s my personal machine) - 10:55

PowerBook G4 1.67Ghz 1.5GB (top of the line of current PowerBooks - before reboot) - 9:42 (Bill)

Mac mini 1.42Ghz 1GB (after reboot) - 9:14 (James)

PowerBook G4 1.67Ghz 1.5GB (top of the line PowerBook - after reboot) - 8:48 (Bill)

PowerMac Dual G4 1.0Ghz 512MB - 6:14

PowerMac Dual G5 2.0Ghz 2GB (before reboot) - 4:31 (Michael Tsai)

PowerMac Dual G5 2.0Ghz (before reboot) - 3:48 (Daniel)

PowerMac Dual G5 2.0Ghz (after reboot) - 3:18 (Daniel)

PowerMac Dual G5 2.0Ghz (after reboot, single user mode) - 3:13 (Daniel)

Developer Transition Kit (DTK) Intel 3.6Ghz Pentium 4 1GB - 3:21

Kubuntu Linux - Athlon64 3200+ (2Ghz) 1GB - 2:59 (Mike PJ)

PowerMac Dual G5 2.0Ghz 2GB (after reboot) - 2:46 (Michael Tsai)

PowerMac Dual G5 2.5Ghz 2.5GB - 2:35 (Mike PJ)

iMac Intel Core Duo 1.83 1.5GB - 2:08 (Steve)

iMac Intel Core Duo 1.83 1GB - 2:06 (Gus)

iMac Intel Core Duo 2.0 2GB (bad test since there were several apps running) - 2:13

iMac Intel Core Duo 2.0 GB - 1:57 (Michael Tsai)

PowerMac Quad G5 2.5Ghz 4GB (still the king) - 1:39 (Jon)

So it looks like the G4s are looking pretty slow nowadays compared to the G5s and Core Duos. The MacBook Pros are coming out in Core Duo 1.67 and 1.83 configurations, so they should come in around 2 to 3 minutes. Jon’s Quad G5 is still the king of the hill… for now. :)

I’m still not sure if it is really twice as fast, from a programmers standpoint, but this is clear: if you’re a programmer on a PowerBook G4, you stand to gain a LOT from upgrading to either a MacBook Pro or an Intel iMac.

Interesting that the DTK, even though Ghz wise matches up with the Core Duos, is significantly slower. In all fairness, it was a prototype development machine, destined never to make it into consumer hands.

Anyone out there want share the numbers they get for any of the iMacs or PowerMac G5s?

Here’s the test instructions:
1. Get Subversion 1.3.0.

2. Do a “configure”.

3. Quit all running apps.

3. Run “time make -j8″. This is important because it will keep your processors running at 100%. (On a single-processor Mac, you should probably use “time make -j2″.)

4. Report back the numbers you get for “real”. This is how long it took to build subversion.

5. (Optional, but makes things more interesting) Reboot. Repeat step 3 and report back both the numbers before and after rebooting.

Update: Steve from Martian who just released SlingShot which syncs folders between Macs sent me some numbers. Thanks Steve!

Update (2/4/2006): Bill Nalens sent me his numbers for the 1.67 Ghz PowerBook, which is the top of the line (and maybe end of the line?) for PowerBook G4s. I think Apple’s claim of 4x might be very accurate for developers. Assuming that the MacBook Pro is a little slower than the iMac, and it comes in at around 2:30 that’s right at 4x the speed of a PowerBook G4.

Mike PJ posted his numbers from his PowerMac Dual G5 and a Linux box. Mike is the developer of Seasonality, an advanced weather monitoring app for OS X. Surprisingly, the PowerMac is bested by the newest iMacs by 15-20%. I think the Intel PowerMac will come back with a vengeance later this year. I guess I should try to break things down further and look at the L2 caches and bus speeds to try to make sense of this.

Update (2/5/2006): I got more numbers from Daniel Jalkut who develops FastScripts and Michael Tsai who develops DropDMG, SpamSieve, and runs ATPM. Michael confirms my belief that the Intel iMac 2.0Ghz is the fastest of the current Macs with the exception of the Quad G5. Well at least for compiling.

What’s more interesting is that Michael and Daniel gave numbers for the same model of PowerMac, the Dual G5 2.0Ghz. Not sure how if the memory is the same, but it ranged from 2:46 to 4:31, which is a pretty big range. It turns out that rebooting can make a big improvement, probably due to some sort of memory leaks?

I also changed the instructions to tell people to quit all running apps and then optionally report a second set of numbers after reboot to see if Michael’s daily reboot suggestion makes a difference.

Update (2/7/2006): I got some more numbers from Daniel, who reported that single user mode doesn’t have much of an impact than regular (multi-user) mode. This is a good indicator that OS X is quite efficient. At startup, you have Finder and Dashboard running in the Dock, plus several other processes running hidden.

I also got some numbers from other Mac models, with an iBook 1.2Ghz bringing up the rear and a Mac mini 1.42Ghz beating out my PowerBook (which is sort of sad - I really should buy an Intel Mac this year) but still bested by the top of the line PowerBook.

There seems to be a debate as to how much benefit you get from rebooting, but I still recommend it at least for this benchmark. Also I’m only reporting the after reboot numbers from now on.

Also Patrick brings up an interesting point - we should build the same thing on both platforms, meaning a Universal Binary. I’ll look into doing something like compiling Adium.

I’m still looking for iMac G5 numbers.

  1. Daniel Jalkut Says:

    PowerMac Dual G5 2.0Mhz - 3:48.

    I quit all of my open applications, but that doesn’t mean that mdimporter and all my Dashboard widgets, etc., weren’t running. I’m a little skeptical of this benchmark because I suspect that everybody’s “idle activities” are quite a bit different. If I had to guess, I would even say that newer machines are liable to have fewer active processes, because the users of those machines haven’t casually started as many widgets or applications with helpful daemons.

  2. Michael Tsai - Blog - Subversion Compilation Benchmarks Says:

    [...] Luis de la Rosa has compiled a list of how long it takes to compile Subversion on various Macs. My iMac Core Duo (2 GHz, 2 GB) took 1:57. My dual-progressor G5 (2 GHz, 2.5 GB) took 4:31 with no applications running, after it had been on for a day. When I restarted and timed it again it was, as expected, much faster: 2:46. [...]

  3. Cameron Hayne Says:

    Here’s some more data on the subversion-compilation benchmark.
    My machine: iBook G4, 1.2 GHz, 768 MB RAM, OS X 10.4.4

    I did the compile 3 times, doing a ‘make clean’ before the 2nd & 3rd times.
    Each compile was done with ‘time make -j2″ (as recommended for a single-processor machine). By the way, I’m using gcc 4.0.1
    In all cases I had a few background processes (mds, cpu-monitor, etc) running and taking a few percent CPU.
    I waited until all the usual startup and login items had completed before doing the compile.

    First time (done when the machine had been up and heavily used with me logged in for 9 days): 12:16
    After logging out and in again: 13:17
    After rebooting: 11:49
    This shows an approx 4% decrease after rebooting - probably not significant. So I’m not seeing the benefits to logging out or rebooting that had been touted by Seth Dillingham & Michael Tsai.

  4. Patrick Machielse Says:

    Looks favourable for the new Intel Macs. But what are we comparing: x86 vs. PowerPC or GCC compiling x86 binaries vs. GCC compiling PowerPC binaries? What’s the incantation for building a Universal Binary from the command line? That may be a better benchmark. (or at least both building the _same_ executable)

  5. James Bailey Says:

    My main development machine is (don’t laugh) a 1.42 GHz Mac mini with 1 GB and a slow 4200 rpm 80 GB drive.

    Just quitting all apps: 9m 26s
    rebooting: 9m 14s

    So, not bad in comparison to some of the above mentioned PowerBook G4 times.

    My MacBook Pro is due for delivery on Feb 23rd. This will be the first time since my Duo 280 that my laptop will be faster than any desktop machine that I own.

    However, my order for G5 Quad was placed today. I am going to use it for double-precision LAPACK/BLAS stuff, were I think it will perform better, as it has eight double precision floating points units and a fused-multiply-add (40 GFlops/s peak performance). The influence of the memory interface on the sustained performance though will be interesting to find out.

  19. Heitzso Says:

    Would appreciate a command line to compile fat binary on ppc emac
    targeting both ppc/intel. Google came here while searching for that
    info because of above comment requesting such a critter. Xcode
    may be great if you live in Mac, but just another hassle otherwise.
    Suggestions? Thanks.

    [...] So what about the benchmarks? I decided to start with the svnmark that Luis introduced on his blog, and downloaded Subversion 1.3.0 (1.3.2 is available, but the last benchmarks I did previously used 1.3.0). After a couple of runs, I found make -j4 to be the quickest. Here are the numbers: [...]

    I did about 4 reboots and builds using j8 and it was consistently 1m02
    Using j4 (just to sanity check) was again a couple of seconds quicker.

  31. 20″ Intel iMac Core 2 Duo svnmark score - Happy Apps Says:

    [...] I got a new 20″ Intel iMac last week. It’s a 2.16Ghz Core 2 Duo and its crazy fast compared to my old PowerBook G4 1.33Ghz. As you may know if you’re a loyal reader of this blog that I like svnmark (compiling subversion) because it is a benchmark that directly shows how much productivity gains you might be able to get if you upgraded your Mac. I mean its nice to see how many frames per second you might get in World of Warcraft, but really - you want to see if more cores / more gigahertz gives you faster compiles. [...]

    Gus - that rocks! I think you should try with make -j16 though and see if you can get those cores working harder. (Unless -j8 already pegged them to 100%)
