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.

    Email Anand or Vivek and tell them to get some Windows Boot Camp numbers! I'd do it myself if I had a Mac, but I'm not willing to buy one just to test Windows. (Note: Vivek *ought* to be doing Windows testing already, so hopefully we'll get numbers sooner rather than later.) Reply

    I think Windows exclusive users should review Windows, like you. We don't want a site like the Verge where dedicated long time Apple fans(aka Verge staff) review Windows in a whimsical fashion. Reply

    I feel "burned" to use Jarred's words by throttling caused by overheating with my 2008 M1330 :( It's performance has become so bad that after watching YouTube videos for half an hour or so it becomes so slow that I switch to my iPhone. It doesn't help that this computer has the defective Nvidia 8400M GS chip which just adds more heat to the mix and causes it to throttle faster. I've been reading about newer Dell XPS laptops in the user reviews and it's common to see someone complaining of throttling due to overheating. I just don't think Dell has the engineering ability to make a powerful computer compact... The one I have now is probably my last Dell for personal use. To be fair to Dell, my work computer is a Precision M4600, and it is huge but has never let me down. For personal use my next one is probably going to a Retina MacBook Pro. Reply

    Agreed, Dell needs to work on improved cooling/thermals. While playing SCII at 1080p/high settings on my Dell 17" XPS L702x I get good framerates (~45-50 fps), but then after I installed HWMonitor I found that CPU temperatures frequently hit 97C after ~1 hour of playing. After seeing this I now run the game at 99% CPU (which disables turboboost), which still gives me ~40 fps, but temperatures now max out about 79C.

    If I hadn't installed HWMonitor and noticed these ridiculous temperatures, I'd probably have a dead motherboard in a year, or worse yet just slightly out of warranty.

    Quality chassis material and conservative/good look - Check
    Good hardware platform - Check
    Adequate platform cooling - Negatory

    I really wanted to see this laptop succeed but saw the ship sinking fast after people on notebookreview's forums started reporting on their received units' throttling and "Faraday cage" wifi issues. Reading your stress bench results with throttlestop put the final nail in the coffin; otherwise, I would have returned my mid 2012 cmbp and save a good chunk of change purchasing Dell's l521x.

    Guess getting all three of those check boxes checked comes at a premium. One that several people are willing to pay if fulfilled.

    form over function.

    throttling is unacceptable.

    i wonder if it can manage not to overheat if the fan is turned to the max.

    Are there any plans for a review of the Envy 15? A friend of mine purchased one for ~$1100 recently, and the hardware and aesthetics make it seem as if it would be an interesting alternative, especially with the IPS Radiance screen option.

    Is HP holding out like they did with the Envy 14 a couple years ago? ;)

    Pretty much. I had hoped we'd get some of the new HP products for review, but so far hat hasn't happened. We'll keep asking, though. Reply
