Performance

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

Photoshop benefits tremendously from the upgrade to 4GB. The application takes advantage of both the faster CPU and larger memory size. The combination of the two bring the 11-inch system within 5% of the 1.86GHz, 2GB 13-inch MacBook Air. A 16% increase in performance over the base 11-inch configuration. Definitely, a tangible improvement.

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

Our Aperture import test is equally impressive. We measured a 14% increase in performance over the base configuration. Although in this case, the 13-inch MBA was still 20% faster than the upgraded 11. Once more, the system didn’t only benchmark quicker, but it felt faster in use.

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.

3D Rendering Performance - Cinebench R10

Cinebench is perfect for isolating the potential for CPU improvement. These tests are entirely CPU bound and as a result we see a ~14% improvement from the upgraded 11 vs. the base model. This is important to confirm because it means that despite the higher clock speed, Apple isn’t aggressively throttling the Core 2 in the upgraded system. If you pay for the extra 200MHz, Apple gives it to you - no strings attached.

3D Rendering Performance - Cinebench R11.5

The only indication of something funny going on was our run through Cinebench 11.5. The multi-threaded score was only 13.5% higher than the 1.4GHz model, indicating that the chip most likely pulled back below 1.6GHz (likely only down to 1.5GHz).

Quicktime H.264 & Handbrake Video Encoding

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

Video Encoding Performance - Quicktime X

Our Quicktime transcode test proved to stress both the CPU and memory upgrades, resulting in a total performance increase of 19.4%. These are significant gains, definitely noticeable in real world use. Despite the huge improvement however, the 13-inch MacBook Air is still 18.8% faster - partly due to clock speed, and partly due to its larger L2 cache.

Video Encoding Performance - Handbrake 0.94

On average the upgraded system was 15% faster than the base 11-inch MacBook Air. The base 13-inch MBA averaged around 19% faster across the board, however in applications/usage models with large memory footprints the faster CPU had effectively no benefit.

    Would someone be kind enough (Anand preferably) and tell me why Apple notebooks, considering they are using same chips, processors etc... are not compared performance wise to the comparable ultraportables and notebooks?

    Why this mac-to-mac only comparison? It just seems disingenuous to compare a PC based laptops (which Macs are) to only their previous versions.. It's always going to be faster.. so the comparison is kind of moot.

    What's more relevant to someone who is considering purchasing an ultraportable is comparing to other PCs and comparing performance, outputs and all the things you get, along with the price.

    For example.. Acer TimelineX series is an ultraportable that's not even comparable to Mac Book Air specs wise and it costs around $750 ($899) retail with i7 processor.

    I'm just curious as to why you have not compared performance in same applications on different PC ultraportables as well?

    I just find this separation of Macs vs everyone else a bit troubling.. It keeps people in the Apple bubble never showing them what the reality really is and to be frank, that''s kind of, one your jobs right? I mean you test and compare stuff to help consumers? Am I wrong?

    Agree 100%.
  • solipsism - Tuesday, November 9, 2010 - link

    I agree with this. I look for a category that matches my needs and then choose from within that category.
  • khimera2000 - Monday, November 8, 2010 - link

    I agree with him. there is no differance in hardware compatibility any more, there OS is based on a PC operating system, and they moved over to intel. there is no custom hardware other then the chips that they use to restrict softwear. there is no longer a reason to seperate them.

    place them against similarly priced PC systems. it cost 1000 for the base and 1300 after upgrades then there should be other systems that cost that much. Not including them looks... Off, like somthing is being hidden.

    Backlit keyboard is indeed very useful, I also strongly agree with the author

    However, a thin and light ultra-portable notebooks are like to MBA11 this realm, how much more Mars techs within can you ask for it? Desire is endless, but it depends on what era, those requirements may lead to a breakthrough on behalf of the future direction but not now, In today's 11-inch netbook market, MBA11 has became the newest pinnacle in this area, prior to this, who had predicted such a unparalleled epoch-making masterpiece was build in such a light and thin case as the MBA11? we should not take too much desire pinned on it, which greatly exceeded it's their own position, the avant-garde is a luxury as expensive as its price , compared to the cost of 399 dollars is not expensive, If the value of spending $ 399 to be measured like this, even totally to measure the pros and cons of MBA11 are stupid, it everyone sure a true that is every 12 to 18 months there will be new listing refresh its performance level, thus providing better value for money, But everyone should realize a fact what you bought bring you the avant-garde enjoyment, in other words what you bought is the future, nothing more fair than this trade. the real imbalance is the consume mentality!

    I agree on the back lit keyboard. but how thin this thing is and how much performance it has... I only see it for buisness users, or people with a Beefcake of a desktop already. truth is that its a really thin notebook that uses last generations hardware. where as other companies are striving for a technical edge, it looks like this time around apple just went for form over function.

    You can keep the MBA11 after seeing how much these pritty apples warp when they drop im really hesitant to nab one of these systems. the one good thing is it does not have an optical drive so we dont have to worry about the slot warping and rendering it uselss like the other macbooks.

    "As I write this final paragraph in the dark cabin of a plane, I do still miss the back-lit keyboard. Apple really should bring that back."
    It should indeed.

    Agree. In very low light levels the key need illuminating. But only a little. No need for "light the room" keys... just micro-glow so that you can orient your fingers on the appropriate keys.

    what about trim support?
  • khimera2000 - Monday, November 8, 2010 - link

    No osx does not support trim, but the SSD is to slow for you to notice the differance. its based on a samsung desing from 08 at a lower bandwith. its not ment for a significant performance, its more for the power saving then anything.
