Dell XPS 13: A Different Kind of Ultrabook
by Dustin Sklavos on March 13, 2012 9:00 AM ESTBattery Life
One of Intel's big mandates for the ultrabook line was for them to have good battery life, and that's a mandate anyone can really get behind. Dell has gone out of their way to further optimize the XPS 13 for better running time, but their optimizations do run afoul of our testing: the screen features an ambient light sensor which will dynamically adjust the brightness depending on how bright the surrounding room is, and while their optimized mode is enabled it's impossible to prevent the system from going to sleep if left idle. As a result, the XPS 13 was tested in our tried-and-true customized "Power Saver" configuration.
It's hard to complain too much about the battery life the XPS 13 produces, but it's also a situation where you have to wonder if a better thermal solution might not pay off dividends here. Jarred has already proven that Intel's "Hurry Up and Get Idle" mantra is actually accurate to Sandy Bridge, and the XPS 13 could stand to run the fan a bit less.
Heat and Noise
This is really where the Dell XPS 13 just isn't as good of a citizen as we wish it was. Under stress testing, we found the XPS 13's core temperatures would idle in the mid forties and then push into the low eighties. That trouble is compounded by the fan noise; the XPS 13 just seems to have a hard time in general dissipating heat. There's a ceiling that it hits, and then the fan will keep running well after the system has stopped being stressed as it slowly but surely tries to get the temperatures back down to the forties. As I mentioned before, once any obstruction is placed under that bottom vent, it's not at all difficult to get the core temperatures into the high nineties.
Fan noise under heavy load is at least 43dBA, and as is customary with the small fans ultrabooks require, the character of the noise is extremely high pitched. Again, this is really going to be the price of admission for an ultrabook. I want to say that Dell probably could have tweaked their fan controls better, but really it's the fact that the whole cooling system just doesn't seem to be as efficient as competing designs.

I'm confused, is the intel cpu $500 more than the equivalent AMD cpu? I agree that the price is high, but I doubt the cpu price is the only thing pushing it.JarredWalton - Tuesday, March 13, 2012 - link
Look at prices on 256GB SSDs and you'll find a major culprit for the price hike.silverblue - Tuesday, March 13, 2012 - link
Agreed. It's a little unfair to lay the blame squarely at the feet of the i7. Besides, Trinity will be very hard pressed to have clocks at that level with a discrete-class GPU and still only fit in its purported 17W envelope.Beenthere - Tuesday, March 13, 2012 - link
When Trinity arrives and delivers the goods people will just laugh at the Ultrabook and the absurd pricing and lack of performance.fic2 - Tuesday, March 13, 2012 - link
Is that an echo from Bulldozer I hear?KitsuneKnight - Tuesday, March 13, 2012 - link
I doubt remember the Bulldozer fans sounding so hilarious...tecknurd - Wednesday, March 14, 2012 - link
Let us see the i3 processor performs better than any A8 processor that AMD has to offer. Sure Intel graphics suck, but what kinds of people are going to use this notebook. Mainly people that are casual users and not gamers. Intel graphics is overwhelming plenty for casual users. The i7 processor is high performance processor, so Intel is still better when Trinity comes out. The cost is related to the SSD, so any AMD system will cost the same. Trinity have to be at least 30% faster or even better 50% better because the highest model of the first generation Bulldozer is just as fast as an Athlon II. Intel's Sandy Bridge i-series processors a much faster than Athlon II and Phenom II processors, so AMD has a lot of work they need to do to catch up. Really AMD have to introduce the third generation of Bulldozer to equal the performance of Sandy Bridge. When that happens Intel has already introduced Haswell. Say all you want but Trinity will not beat Intel's offering even you troll hard enough. It just not going to happen. AMD's arrogance is getting in their way of making highly competitive processors.Autisticgramma - Tuesday, March 13, 2012 - link
Its a pc with Aesthetics. Otherwise known as a wannabe apple. The reason it sucks so much is, what dell is attempting to produce is a product with apple's margin, via apples looks. Again no dice. I'd be happy if Dell stuck with what made it the behemoth it is. Ugly office hardware that works. There's a reason office PC's look like crap. So you don't stea - I mean 'misplace' them.What ever happened to computer parts on anandtech? I mean tablets and phones, share parts with computers. If I want a real part review sadly I must visit another site these days. I mean for an apples to apples comparison. "Today were testing the Samsung Galaxy S II against the nVidia 580, in direct x 11 applications...."
(Hyperbole may have been used to convey the feeling of disappointment with the declining quality of my favorite site.)

Anandtech runs "computer parts" articles all the time.They have more editors than they used to, so there is more room for other types of hardware.
Of course, I don't expect you to understand that even after it's pointed out, because the first part of your post demonstrates that you "wannabe" a person who can think.

"Its a pc with Aesthetics. Otherwise known as a wannabe apple. "What? There are plenty of "wannabe" Apple products out there, but you're only criteria is good aesthetics? That makes no sense. This looks like a good original design to me, ventilation aside.
