Introducing Dell’s XPS 15 L521x: the 2012 Update

I’ve had some good experiences with Dell’s XPS line of laptops over the years, but in virtually every case I’ve had a few minor complaints. The earlier models were large, fast, and too expensive for most users. Then Dell dropped the XPS line for a while and went with the Studio XPS—still generally expensive and there were performance elements that came up short (e.g. the Studio XPS 16 had an awesome RGBLED backlit display, but it tended to run a bit toasty and the hardware wasn’t as fast as previous XPS offerings). With the relaunch of the XPS line in late 2010, the original XPS 15 delivered a great display and a well-balanced set of components that was enough to earn our Gold Editor’s Choice award, but the chassis was understandably a bit too bulbous for some tastes. The XPS 15 Sandy Bridge update improved the CPU and GPU options, but six months after the first XPS 15 I was even less enamored with the chassis.

Next up in the list of progression was the XPS 15z, which improved some areas but regressed in others. It had a thinner, sleeker looking chassis, but dropped support for quad-core processors, downgraded the GPU slightly, had some thermal concerns, and perhaps most worrisome was the build quality. I posted an update a few months after the review that summed things up nicely: “I can't stress enough how it feels like Dell cut a few corners and the result is a laptop that doesn't hold up as well as I'd like over the long haul…. When the inevitable Ivy Bridge update of the 15z comes out, you can bet I'm going to pound on it a little more.” And that brings us to the new XPS 15, which has a completely redesigned chassis. Did Dell listen to my complaints about the 15z build quality? You better believe it!

Superficially, the new XPS 15 looks quite similar to the 15z, at least in pictures. Meet one in person, however, and the changes are immediately noticeable. Many suggested that the XPS 15z was trying to clone Apple’s MacBook Pro, but that’s somewhat disingenuous—unless you consider any laptop that aims to be slimmer and silver to be a MBP clone, I suppose. I would however suggest that it did take more than a couple design cues from Cupertino, including a strikingly similar keyboard layout. The newest model keeps the 15z keyboard layout (which is still a step back from the XPS 15 L501x/L502x in my opinion), but ditches the silver palm rest and keyboard area for a matte black surface with a soft-touch coating. The touchpad also gets a clickable MBP-like interface that we’ve seen on just about every Ultrabook along with many newer laptops. Personally, I still prefer touchpads with separate non-integrated buttons, so this is another step back.

What’s not a step back is the chassis itself, which is now the most MacBook Pro-like chassis I’ve encountered in a non-Apple product. It uses machined aluminum for the main chassis and frame, similar to Apple’s unibody chassis, and it’s thicker and far more rigid than any previous Dell XPS laptop. Even the display cover gets a thick aluminum backing, so there’s really no twisting or flexing to speak of. The palm rest on the other hand isn’t machined aluminum but instead uses magnesium with a soft-touch coating. If you thought the XPS 15z copied a lot of Apple’s design, the XPS 15 will only cement that impression, but really I don’t care: if a competing product is better, then stealing a few ideas isn’t going to hurt my review of it. [Insert obligatory Steve Jobs quote about great artists stealing….]

Here’s the spec sheet for the new XPS 15, and I’ve included the specs of the last-gen MacBook Pro 15 as a reference point. Note that unlike the MacBook Pro Retina, Dell continues to include a DVDRW/Blu-ray optical drive with their XPS 15.

The “on paper” matchup between the Apple and Dell laptops ends up being quite interesting. Not surprisingly, even the base model MacBook Pro 15 is quite a bit more expensive than the mid-tier XPS 15. (There’s a dual-core model XPS 15 that comes with an i5-3210M CPU, GT 630M 1GB GDDR5, 6GB RAM, 500GB HDD + 32GB mSATA SSD, 1080p LCD, and DVDRW for $1300 if you’re interested.) In many key areas, Dell comes out ahead of Apple this round: they have a higher resolution LCD standard, you get 8GB DDR3-1600, they use a 750GB 7200RPM HDD with a 32GB mSATA SSD caching drive (via Intel’s Smart Response Technology), you get a Blu-ray combo drive, and there’s a third USB 3.0 port plus HDMI and DisplayPort outputs.

However, that’s not the whole story: Apple uses a full voltage 45W i7-3610QM processor, which boasts slightly higher clock speeds than the 35W 3612QM, and they also use a GT 650M GPU that comes with higher core clocks. Let’s also not forget the FireWire 800 port (well, I’ve never used FireWire so actually I can forget about it…), or more importantly the Thunderbolt port. Apple also uses a higher capacity battery configuration and provides a 450Mbps capable (dual-band 3x3:3 MIMO) wireless adapter.

Perhaps more interesting than the differences are the areas where they’re the same. Both laptops have machined aluminum chassis, and the dimensions are very close to a tie. Apple isn’t quite as wide, thanks to their 16:10 aspect ratio display, but the Dell XPS 15 is actually slightly thinner. Despite the relatively similar dimensions, Apple still manages to come in 0.2 pounds lighter, but for this size laptop that’s close enough for all practical purposes.

So which laptop is better? In the past, I’ve always felt that Dell’s attempts to compete with Apple came up a bit short. The first XPS 15 (L501x/L502x) was a nice change of pace from previous Dell designs, but it wasn’t really close to Apple in terms of overall design. The XPS 15z got the form factor right in my opinion, but build quality still went to Apple—plus you were limited to dual-core CPUs. I would also say the same thing about HP’s Envy line—they’ve had some nice looking laptops for sure, but I’ve never felt they could match Apple’s overall build quality (though I would rank the previous models slightly ahead of Dell’s older XPS offerings). This time, build quality is absolutely top notch for the new XPS 15, and the only thing that really differentiates it from the MacBook Pro is the black palm rest with soft-touch coating, and the silicone on the bottom of the chassis.

What it really comes down to is one thing: do you prefer running Windows or are you an OS X devotee? Sure, you can always run Windows on a MacBook in a pinch (or you could try to make a Hackintosh), but as we’ve shown in the past there’s a penalty in terms of battery life if you choose that route. If you have never owned a MacBook Pro, there’s a good chance you fall into the camp of users that admire Apple’s designs but couldn’t care less about their OS—which is exactly my feeling. Now, we have a truly viable alternative for the MacBook Pro (though sadly there’s nothing even remotely close to the MacBook Pro Retina, of course). And guess what? You’ll pay more; yes, it’s true: quality has a price.

I’m not sure exactly how much of the added cost comes from the sturdier and slimmer chassis, but if we look at competing Windows laptops (e.g. ASUS N56VZ), you can actually get pretty much the same specs from a laptop for just $1000. There’s no doubt in my mind that the XPS 15 is built better than the N56VZ, but I’ve been using a similar ASUS laptop for a couple months now and the only thing that’s really missing in my mind is solid state storage—which you can easily add on your own. The ASUS should also be slightly faster on the CPU side, though the use of DDR3 memory on the GPU makes it a bit of a wash. Based purely on the overall design and features, I’d go with the Dell XPS 15, but at a 60% price premium the ASUS is clearly the better bargain.

    "I think the Acer M3 looks might tempting value when looking at the graphs. It's got about 90% of the power for about 50% of the price"

    I think it would behoove you to do a bit of research on Acer products. By reading through user reviews from where ever you can find them. Most likely you will find many, many negative reviews. After that try talking to a few people you know personally who have owned Acer laptops.

    Also if driver support is important for you. In the past Acer has been terrible in this department. Even if a well known part is included, you might find that upgrading your drivers might turn out to be a huge hassle, or even impossible.

    If you're looking for a good deal though Dell, and many other companies have good deals a couple times a year. Usually found on deal sites like You have to pay attention for a while, and be fast though . . .

    I got an Acer for my dad and it's doing just fine after 3 years and he takes it out to do research on once or twice a week. I know a lot of people joke about them and that Thinkpads and Macs are better built but plenty of people say that they're actually ok with their Acers (it would behoove you to read a bit wider too I think).

    People on anandtech and other tech sites are usually enthusiasts who often spend money on better kit but I can't afford to spend $100s on better build when Acer quality is 'good enough'. Either way it'll have to be upgraded in 5 years anyway. Mercedez and BMW have better build than Fords or Vauxhalls but I can't afford them either.
  • yyrkoon - Saturday, July 28, 2012 - link

    Point being. You can pick up some incredibly great deals by not impulse buying. Without having to sacrifice too much.

    Just right now there is an HP with a core i5 processor (2.4Ghz ) 6 gb RAM, an AMD 7670, with a 750GB HDD for under $600 ($575) Which I am almost willing to bet will outperform the reviewed laptop as it sits.

    You're right though. Personally I can not afford to buy just any old laptop either. For many reasons. Cost is only one small aspect. Also, I can not afford to spend x amount of money only to have the darned thing break, and have it replaced, or spend money set aside for other things on shipping. To get the system repaired.

    With all that said. I too have found several Acer systems tempting. Then I remember what I have written in the paragraph above. Which is I do not have time / money to spend screwing around with something that should already be working as intended. My values here are obviously going to be different than yours. As I have certain things I will put up with, and some which I will not.

    Some cal that "peace of mind" Which is why Mercedes, and BMW exists.

    Except that piece of mind often breaks down on the high end laptops as well.
    Lots of lemons there, too.

    A better way to go about it is not get the latest thing until enough test bunnies have done so and beaten it approrpiately to have a good answer on what doesn't work and what breaks.

    I have to agree with the other fellow, I've seen a lot of Acer laptops that do well (perfect nothing breaks)over a very long haul, even many Vista models. Their downside is bloatware, and sometimes the re-installation of the webcam on a flat Win install - which can be a real pain - but that also occurs on Asus and other high end laptops.

    So the bottom line is, bragging rights.
  • yyrkoon - Tuesday, July 31, 2012 - link

    Well, I own an Asus, and it cost me $400. Plays games all at acceptable speeds. and all that.

    Own a Toshiba too, which also cost me $400 brand new. Doesn't play a lot of recent titles well, but it has served it's purpose. It is also 5 years old, looks and operates as if brand new.

    Neither of these gave me issues when it came time to upgrade, or retrograde. Period, Both companies have drivers for just about every reasonable solution out there. And then some.

    Also, that Acer M3 as reviewed by this site, sells for $1800 . . . SO yeah screw that. I can pick up and Asus with much better hardware, and software support for half the cost.
  • CeriseCogburn - Sunday, July 29, 2012 - link

    You see concerning this metal encased mac clone, they will put up with nearly anything and live with it.

    Instead one could get a thicker off brand or branded beast and have zero throttling issues and a much prettier screen, but you know, when they are going for the drooling braggart's right to squirt that they have an aluminum shell, anything goes.
  • Zak - Saturday, July 28, 2012 - link

    That's a really good looking laptop. What happened? Did Dell finally hired someone with sense of aesthetics??? But yeah, that trackpad is likely to be a problem for many. Reply
  • CeriseCogburn - Sunday, July 29, 2012 - link

    Looks like a plain jane piece of crap to me - and I can clearly see the mac clone rounded corners.
    It's all in the heads of the wannabe in crowd - sad, really sad.

    I use a MBP and I'm a little disappointed to see Dell reaching for a near four-year old design, but not being able to nail the thermals. My machine gets warm, but hasn't ever overheated. But the biggest concern is that customization is limited - even more than Apple. When I click on the configs in the Dell site, I can customize the software, but that's about it.

    As for Apple not being innovative, you can say that about every other company in business today. They all stand on the shoulders of those who came before them. But as this demonstrates, how components are assembled and in what sort of enclosure does matter, especially in a laptop. Milling most of the structure out of a single piece of Al is pretty impressive. The fact that Apple can make laptops with fast CPUs and dedicated graphics that still manage to be under 1" thin and less than 6lbs is pretty good.

    But one of the biggest criticisms of Apple has been the lack of options. It seems that Dell is moving toward selling fewer hardware configuration to keep costs down. Too bad, used to be one of their selling points.
  • yyrkoon - Wednesday, August 1, 2012 - link

    No one can say that Apple does not assemble good parts into their MBP laptops. That is, if they expect to be taken seriously. Yes, their cases are superb too.

    However, for people like me, that is not where the problem lies with Apple. In short, proprietary hardware, using proprietary software. At too much cost.

    IF Apple sold their hardware, and Operating system separately / standalone. Personally I would have far fewer issues with them as a company. Also, I do not like their business model for their other mobile products

    Honestly, I have about as much problem with Apple as I do with Microsoft. Maybe slightly more. Thing is, with Windows. IF it stops working for me. I can switch to Linux, BSD, or whatever other Operating system I care to use. All my own choice. On top of all that, i get to choose my own hardware as well.

    So yeah, for me and people like me. "It simply *does not* work". Of course, we actually know how to use a computer too . . .
