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.

Both Atom and Sandy /Ivy Bridge uses 4 thread compared to 2 threads the Cortex A15 uses. A better comparison would be a Quad Core A15. Which free the Core from doing other work in a Single Threaded Benchmarks and better illustrate mutithreaded performance.The A50 will offer 20 - 30% performance increase compared to A15 at 32 bit and further improvement at 64bit mode. This, with higher frequency and Quad Core or Hex Core will surely bridge the gap between everyday Laptop and a Chromebook.

It doesn't matter. HT is pretty gimmicky anyway. You can maybe 10% improvement in performance.Don't forget A57 will not just have better IPC than A15, but will also go to higher clock speeds - up to 3 Ghz, actually. A quad core A57 chip at 3 Ghz will be more than enough performance for most people, while having very good battery life.

"Plugging the Chromebook into a relatively modern (~2 year old) Samsung LED backlit LCD HTDV caused the Chromebook to reboot itself."i dont know why but I burst into laughter when i saw this....

Any word on the ship date for the 3g version? I preordered one on Amazon on the 19th, no word on ship date and I can't find one mentioned anywhere.TrackSmart - Thursday, November 1, 2012 - link
I opened this page and got taken here: http://testables.net/d/juicyru.comI'm guessing this is not what you guys agreed to regarding what advertisements on your site can do. Here's the brilliant message you get:

"PC notebooks that still struggled with the same virus/malware issues they'd been facing for years"That comment had me confused. Is he talking about the crap companies put onto their non-business notebooks or did I miss some sort of virus/malware hell in 2010 that somehow later got solved?

This could be better, but it is okI have seen worst than this
What did you expect with so low price
This does not work but let's see something else that works
And here it is a USB 3.0 that works as a slow USB 2.0, and here it is a slot that it is not a slot but a hole
More or less this is what I was reading in this article. So you pay $249 and you buy a very light machine with overall poor quality and an OS that it is very limited in what you can do with it. And only 6 hour battery time?
Better buy a netbook, tablet or a second hand laptop for that price.

"Note that the previous Atom solution required two chips: the N570 and its NM10 Express PCH. The !!! -= N570 =- !!! had a 2.1W TDP and was used for all IO, while the N570 and its two Atom cores needed about 8.5W. "I guess that is the NM10 actually? Otherwise it makes no sense, to me at least.
I keep reading and loved the expression that "ARM is the new AMD", perhaps we should call them "ARMeD", since they are in the same boat now.

Anyone care to take a guess on how much this device would retail for if it included a battery with 50% or 100% more capacity? That would be a 45 or 60 Whr battery, respectively. I think it would fairly useful to be able to pull 9 hours from a single charge.
