Samsung Chromebook (XE303) Review: Testing ARM's Cortex A15
by Anand Lal Shimpi on October 31, 2012 9:00 AM ESTUser Experience & Usability
Similar to our performance analysis in the Surface review, there are really two sides to the performance of a Chromebook. There's the user experience as well as what the underlying hardware is capable of. I'll start with the user experience.
Chromebooks have never been all that robust when it comes to user experience. When Google first announced them they didn't even support mounting USB storage, although that has since been rectified. Although Google may have grand visions for where Chrome OS could go, today it serves one real purpose: to provide an affordable platform for a good web experience free of viruses and malware. To that end, the new Chromebook accomplishes its goal fairly well - as did the devices that came before it.
Chrome tends to be my favorite browser, and the experience maps fairly well the Chromebook platform. Web pages render properly and quickly (given the hardware that is). Compatibility isn't an issue. Everything just seems to work.
Obviously a major selling point of Chrome OS is that the web now allows for many content rich applications to be delivered directly in the browser rather than through a standalone executable. Google helps give access to these applications through the Chrome Web Store, although it's important to note that not all of them will run on the ARM based Chromebook (nor is there a good listing of those that will/won't run). The apps themselves vary in type from simple games to productivity tools. Many are quite functional, but the performance just isn't very good compared to a $500 tablet or even a $500 PC.
Technically the Chromebook can do a lot, but for anything other than browsing, YouTube and Google docs use I wouldn't get my hopes up. The heavier apps just don't run smoothly on the platform. Even web browsing isn't what I'd consider fast, but it's still acceptable. To put things in perspective, I got a performance warning trying to play Cut the Rope on the new Chromebook. Stability can also be a problem. Try to deviate too much from normal web browsing and you'll be greeted with long pauses and even system locks. For example, while testing WebGL performance on the new Chromebook I had to power cycle the machine after the browser became unresponsive. Normal web browsing is fine though.
There are other annoyances that aren't strictly performance related. For example, Netflix streaming won't work on the new Chromebook. Although image browsing support is native to the OS, there's no support for RAW camera files from a DSLR.
For the basic necessities however, the Chromebook does embody the fast enough computing concept. I researched, wrote and did almost all of my work while preparing this review on the Chromebook and generally found the experience acceptable. Other features like Pandora worked just fine (although I'd occasionally get hiccups in music playback if I loaded a particularly complex page). Whenever I'd switch back to my Ivy Bridge notebook I'd really appreciate the extra speed, but for writing and web browsing duties the Chromebook got the job done. Had Chrome OS been built around a lesser browser I don't think I would be as positive about the experience.

Yeah, basically this next gen 22nm Atom core is going to be make it of break it for the Atom. I can see the Atom getting canned entirely if the 2nd gen core on 22nm sucks.andrewaggb - Wednesday, October 31, 2012 - link
Yeah, intel must be feeling crazy pressure. They are 6-12 months behind. Both Haswell and the new atom should be coming out now with windows 8.amdwilliam1985 - Wednesday, October 31, 2012 - link
I'm impressed by the ARM performance, besides the performance and battery life, there is also the cost to consider. As far as I know, ARM cpu cost much less than x86 cpu.If I can get 50% of power for 25% of the price, that sounds like a good trade off in many scenarios.

The samsung arm a15 is basically a 6+ w SOC... If you linear scale the medfield up 3 times, it means a three core atom, and three times the graphic power (does scale linearly), and i think the performance is comparable. The medfeld is arround 64 mm2, and the three core atom and graphic is, to my best guess, 100mm2, any one give me a estimation of the die size of the samsung a15? we can calculate the price :)krumme - Friday, November 2, 2012 - link
The intereting thing is the total cost for the OEM. The A15 implemented as here must be dirt cheap.Intel have high fixed cost, but arm can spread the cost to phones whatever through both Samsung but primarily TSMC.
In the long run it will be difficult for Intel the have the same low cost.
Years back they could use old fab equipment for the Atom and in that way use production capacity that had been written off the the worst part. Today they they need the new process nodes to be competitive, and that will raise cost for the Atom. I think they are in a bad market here.
Competing with TSMC and Samung is another world from competing with AMD and GF.
They need their ultrabooks, but the market is to small for the future fab cost.
Now arm can share cost from phones to notebooks. That is massive cost advantage imho.

A chromebook is too niche a product to properly judge a SoC . Typically thermals are completely different.Its fast, yes, but how will it do in a smartphone ? And chromeOS has too few apps and the chromebook has too less a res to actually judge the best SoC .....

Not like the Atom one was using bigger resolution. And Exynos 5 Dual can support up to 2560x1600, as we've already seen with Nexus 10.MilwaukeeMike - Wednesday, October 31, 2012 - link
Maybe I missed it, but does this have a built in webcam? Looks like it does from info on other sites, and I'd like to know how it performs for Skype purposes if anyone knows. Sounds like videos from youtube/facebook work ok as well, which would make this a great netbook style option.deneb - Wednesday, October 31, 2012 - link
For that price, why wouldn't anyone get a used laptop instead? At least then they'll get the benefit of a proper OS of their choice (linux or Windows, i don't know if used apple lappies go that low).Granted, it wouldn't be new, but at least it would be many times more functional - no? :)

Battery life. A old low end laptop is going to have terrible battery life.
