Performance

Benchmarking under OS X isn’t difficult, you just need to get creative. Luckily I’m in dire need of creative outlets so creating OS X benchmarks works for me. I’m using the same tests I introduced in my Holiday 2009 Macbook Pro roundup and running on the launch hardware for each notebook listed in the charts.

We’ll start with general application performance.

General OS usage is a difficult thing to quantify, but one measure of performance has always been the number of bounces an icon in the dock makes before an application loads. I decided to take it to the next level and write a quick script to launch 15 applications in a row, timing how long the entire process takes.

I launched, in order: Mail, Safari, Activity Monitor, iTunes, iCal, DVD Player, iPhoto, Photo Booth, Quicktime Player, Disk Utility, Preview, iMovie, Front Row, Garage Band and Aperture.

The entire process stresses both the disk and CPU, which is why we see a huge improvement when going to an SSD as well as differences between CPU speeds.

General OS Performance

What a difference an SSD can make. The 13-inch MacBook Air is the fastest standard shipping configuration Apple offers in this benchmark. The fact that there's a measurable difference between the 13-inch and 11-inch models shows you just how slow that 1.4GHz Core 2 really is.

Adobe Photoshop CS4 Performance

The Retouch Artists Speed Test we use for our CPU testing under Windows also works under OS X. We're running the exact same benchmark here, basically performing a bunch of image manipulations and filters and timing the entire process.

Adobe Photoshop CS4 Performance

The 13-inch MacBook Air performs as well as last year's 13-inch MacBook Pro. But if you plan on doing real work, you'll be hampered by the performance of these systems. Apple really needs to find a way to get an Arrandale or Sandy Bridge into this chassis

Aperture 2 RAW Import

For my Aperture test I simply timed how long it took to import 203 12MP RAW images into the library.

Aperture 2 RAW Import Performance

The SSD makes the 13-inch MacBook Air far more competitive than it should be here. It's even faster than a two year old 15-inch MacBook Pro. The 11-inch MBA is faster than the old 13-inch MBA due to its better thermal characteristics as we pointed out earlier.

Cinebench R10

I’m a fan of the Cinebench test because it lets me show off both single and multithreaded performance in the same workload. First, the single threaded performance:

3D Rendering Performance - Cinebench R10

3D Rendering Performance - Cinebench R10

The performance in both of these tests in line with the rest of the results. These notebooks aren't very good at intensive workloads. It is worth pointing out that the 13-inch MacBook Air posts better numbers here than the old dual processor 2.5GHz PowerMac G5 :)

Quicktime H.264 Video Encoding

Our final benchmark is more consumer focused. Here I'm taking an XviD and converting it to an iPhone-supported H.264 format.

    Instead of "jives with" should be "jibes with" ...

    I'm a huge Apple fan - but I'm just not drinking the kool-aid on this one.

    I have a 15" MBP and it's really not that bad to carry around. It also gets like 5-8 hours of battery life (3-4 with VMWare running) and it runs Windows 7 under VMware very well with 8 GB of RAM. I've never considered portability an issue and while it's an expensive machine, I don't think you'd own an MBA. I doubt the MBA would have nearly that type of battery life under VMWare.

    The iPad seems like a better form factor for the "couch computer" (i.e. looking up shit on IMDB or googling something to settle an argument while watching football.)

    IMO the MBA seems like a poor man's MBP. i.e. for students looking for a cheaper computer; the "super-thin" part seems almost like a gimmick to convince people it's a premium product. Really, the only drawback of the 15" MBP (even the lowest-specced one) is the price.

    The thing's hardly faster than my Ion netbook. There will be lots of thin designs coming out like what Intel showed at Computex. Core 2's two generations behind.

    For now, I think the Acer TimeLineX 3820TG is still the best ultraportable laptop (certainly the fastest anyway).
  • zsero - Wednesday, October 27, 2010 - link

    As for an alternative for sub 5 lbs powerful laptops and as for the M11x being fast: I am typing this line on a Acer TimelineX 3820TG with 450M and switchable HD5650, which is on a totally different level than either the MBA or the Dell (while being half the price).
    - 3.9 lbs
    - it can do 9000-10000 points in 3dmark06 easily with a little bit of raised clocks (one click in AMD GPU tool). In games it's even faster, as the ATI cards are much better in real games than in benchmarks.
    - if you are lucky, you can overclock CPU to 3.3 Ghz (or swap to a 580M and OC-it to 3.8 Ghz, with sub-75C temperatures!)
    - and easily do 6-8 hours while web surfing
    - has dual fan / dual heatpipe cooling

    Other than that, it has the most horrible keyboard I have ever seen, with a cheap AUO screen, noisy mic and poor warranty service and a gazillion of running applications, including two real-time virus scanners on the factory install. But a review would be really interesting to see! I seriously think the 3820TG with HD5650 is without alternative in the powerful but portable notebooks, if possible, please make a review about it! (in North America, I think it's only available with 370M processor, while in Asia they sell it with anything up to 640M).

    Intresting system, but i wouldent use it. the keyboard looks to have flex under light loads, making me think that although it looks great on the outside the inside might of had to make some structual sacrifices for the bigger specs, not to mention that the lack of a backlit keyboard would make it more inconveniant compared to what i have now.

    But it does like they are trying to improve there build quality, its just not to the point that i would like.

    As nice as the specs are, i just cant bring myself to trust there build quality just yet, however it does look like there at least trying to improve so who knows perhaps there will be an acer on my list of potentials the next time im do for a notebook upgrade.

    as for comparison to the air... i think there oppisets in some respects. the air's performance although weak at best can still fit in nearly any bag making it conveniant to find a place to stow it for those who have bags full of books and junk, where as the acer trys to push for a more heavy multimedia experiance with a good compact form facter and a extended battery.

    1/ SD card reader
    2/ mic on front for skype/VoIP

    The 11" netbook would be a absolute winner (and an order of magnitude upgrade for people using Atom netbooks) . But why did they miss the SD card reader? This is so obvious, and a determining feature what makes one brand/model of netbook a winner over another brand/model. Such a simple and cheap port. Even the iPad has an SD card reader!

    And what on earth are they doing putting the mic on the side like that? While it *might* be OK when sitting indoors at a tidy desk without other ambient noise, it certainly is not clever in most "real world" situations.

    I would love to replace my ever-so-slightly too noisy and underpowered (but magnificent screen and full of ports) SONY W11 netbook. But no, not until Apple fix the mic location and provide an SD slot.

    (I use SD slot for camera - saving local or uploading to fileserver/website, for camcorder - and immediate playback of material recorded, for old-fashioned mailing of data/documents, for a TASCAM HQ digital audio recorder, and for file transfer with colleagues and for file backup when out of the office, I need highest possible robust mic for indoor and outdoor skype/VoIP where my office telephone is forwarded to my laptop through SIP )

    These two points may seem like tiny features, but I think for many people they are showstoppers.
  • johnspierce - Wednesday, October 27, 2010 - link

    I'm not sure why everyone thinks an SD card slot is a "must have". For one thing, there are still quite a few cameras that *don't* use SD cards (like virtually any high-end DSLR) and putting a technology in your laptop that might not even be viable in 3-5 years is not exactly a good idea. Buy a 9-in-1 card reader. They are like $20. They are about the size of a deck of cards and can handle almost any type of flash.

    I would MUCH rather have a 3.0 USB than a SD card slot -- infinitely more useful.
  • kmmatney - Wednesday, October 27, 2010 - link

    SD slots are useful for permanent storage. I have an 80GB SSD in my Dell Inspiron 9400 laptop, but needed a little more storage. So I just keep a 32 GB card in the SD slot, and it gave me enough room for everything I need. I use it mainly for documents, presentations, and backups of important work from teh SSD. It only sticks out about 2 mm, so I can keep it on all the time. I've even run VMware images from it, and it wasn't too bad.

    I agree that a USB 3.0 slot is useful as well, but wouldn't want to lose the SD slot - its like having a second, easily removable, hard drive.

  • khimera2000 - Wednesday, October 27, 2010 - link

    I see it as a replacemenct for the optical drive, since its also used in cameras, video recorders, and ebook readers (i have an SLR that uses these and a ebook) it makes them alot more conveniant since most notebooks come with the slot already. it puts the macbook at a disadvantage becaus now people have to carry around a card reader that would not be neaded on other notebooks.

    It would be such an inconveniance if i had to drag around a reader with me, and since alot of apple users do photo and video editing it looks like a bad oversight not being able to transfer images and videos without extra required hardware.

    So I am posting late here. I read this last night, but was too tired to respond.

    So now a lot has already been said. But here is one thing that keeps boggling me.

    WHY do people keep calling this a Netbook when it clearly *IS NOT*. The 11.6" MBA is an ultraportable. In line with other ultraportables out there. Its not a cheap piece of plastic with a laughable screen, keyboard, graphics, or atom processor. The benchmarks clearly show this machine to run circles around an atom.

    And if you compare it to similar machines of weight, size, and speed its not far off the mark from a price concern either.

    Is it a perfect machine, no... But it looks like it will fill the gap that has been missing from the Apple product line since the demise of the 12" PowerBook.
