Dell XPS L501x: Windows' MacBook Pro Alternative

We've lamented the state of Windows laptops on numerous occasions; the formula is "tried and true", but that doesn't mean we like it. Put in reasonably fast components, give us sufficient memory and hard drive capacity…and then match this with a cheap (usually glossy) plastic case and the least expensive (again, glossy) LCD panel you can find. Acer (and sub-company Gateway) has truly perfected the art, with a keyboard that all three of our laptop reviewers dislike/loathe/vilify, but they're certainly not the only culprit. ASUS, Toshiba, Dell, HP, and many others use variations of the same basic pattern, and what we're left with is a matter of finding out who if anyone can make something that truly stands out from the crowd.

Of course, if we're talking about standing out from the crowd, one name almost immediately comes to mind: Apple. Love 'em or hate 'em, Apple has definitely put more time and energy into creating a compelling mobile experience. It starts with building a high quality system, but it reaches beyond that into the core OS X experience. Whatever Apple is doing, the result is significantly better battery life under OS X for the components and battery capacity—and as we've shown, moving to Windows 7 largely negates any battery life advantage.

HP created their Envy line to go after the same target market, only forget the OS X stuff and simply build a better consumer notebook that doesn't feel like a cheap piece of plastic. Now, Dell is throwing its hat into the ring with the return of their XPS line. Yes, you could argue that the Studio XPS went after the same market, but the chassis now comes with a magnesium-alloy frame and eschews glossy plastic; the result looks and feels better (in our opinion) than the old Studio XPS 16. Dell also ships Waves Audio Maxx and JBL certified speakers on all the new XPS models, with a claim that these are the best laptop speakers on the market. We'll try to put that claim to the test, but before we get to the evaluation here's the specifications on our test system.

Most of the specs are standard stuff, but a few areas stand out from the crowd. One clear advantage over competing laptops is the 1080p LCD, and it takes about two seconds after you first power on the laptop to determine that yes, we have a winner here! Throw in what is obviously a higher-than-500:1 contrast ratio and the 1080p resolution and we're sold. The high color gamut (~100% AdobeRGB 1998) means the picture looks oversaturated at times, but given the choice between a 45% gamut and a 100% gamut we'll take the latter. What's great is that the total price of the LCD upgrade is only $130, and considering the amount of time you spend staring at the display it's money well spent in our book!

The speakers are another item where the XPS is head and shoulders above the crowd. The subwoofer adds much-needed bass, and sound clarity in general is very good. The Waves Maxx Audio 3 might matter more for audio professionals that regular users, but Waves does give you quite a few options for tweaking the way your laptop sounds. You won't be replacing your home theater system with laptop speakers, obviously, but the L501x can get very loud and do so without severe distortion. Personally, these rate as the best laptop speakers I've used (which isn't saying much), but how important that is depends on the individual.

Similar to the Waves audio in terms of how much it will matter is the HD webcam, and this is apparently the first Skype HD certified laptop. With H.264 support, the webcam in theory allows you to chat with others and get a higher quality video, though the video you get still depends on the other user's camera. In practice, getting an HD video connection with Skype requires at least 512Kbps of bandwidth in both directions, and even when you have that it doesn't always work. The webcam does work fine otherwise, but we never did manage a high quality HD video conference, perhaps because of bandwidth limitations (even though we tested on a 12/1Mb connection).

As mentioned, this is our first encounter with a mainstream NVIDIA 400M part, and we're quite curious to see how the 420M compares to the previous generation parts. NVIDIA has given us an estimate of 30% faster, but that would probably mean 30% faster than the 320M, which would make the 420M around the same performance as GT 335M—only with DX11 support naturally. In other words, we don't expect to be blown away by the 420M, especially if we try to run games at the 1080p LCD resolution! 400M also means the HDMI port is version 1.4, and there's a mini DisplayPort connection as well. This isn't a gaming laptop, unlike some of the previous XPS designs, but it will handle "mainstream" gaming…at a lower resolution than the 1080p panel. Thankfully, you can run at lower resolutions, and the panel is great in multimedia and general use even if 1080p requires quite a bit more GPU before it becomes reasonable.

Of the remaining features, only two final items are worthy of note. One is the backlit keyboard and the other is USB 3.0 ports—two of them. The keyboard isn't your typical chiclet option either; while it may not displace the ThinkPads for comfort, it works well. There's an eSATA/USB 2.0 combo port as well, so while expansion options don't include ExpressCard and you miss the Firewire port (sorry Dustin!), everything else you'd expect on a good mainstream notebook is here. Other extras like a Blu-ray combo drive, Bluetooth 3.0, a 2-year warranty, faster CPUs, a GeForce GT 435M, and a larger hard drive (or an SSD) are also available if you're interested. We do have one complaint about the upgrades, however: you can only order the faster 435M GPU if you get a quad-core CPU, which means you lose Optimus support in the process. The CPU+GPU upgrade also bumps the power adapter up to a larger 130W unit in place of the normal 90W brick, which addresses a problem some users experienced with CPU/GPU throttling on the old Studio XPS 16.

Given the price, what we have is Dell's direct competitor to Apple's entry-level MacBook, and frankly there's no competition in performance or features. The MacBook only leads if you want one of two things: a smaller size, or the ability to run OS X (without going the Hackintosh route). The standard 6-cell battery provides good if not great battery life, while an upgraded 92Wh 9-cell battery should provide for all-day computing if you don't try watching videos or playing games. The specs of our slightly upgraded unit also compete very well against the ASUS N82Jv—similar performance with a dramatically superior LCD—as well as the HP Envy line. If you pick the L501x up on one Dell's routine sales (i.e. the current sale available on all but the entry-level unit) you can cut costs even more. With improved build quality and features, the new XPS L501x is a great update to the old Studio XPS 16; the name change doesn't really matter in our book, as we thought the old model was good regardless, but Dell has addressed all the areas where users had complaints and produced a very compelling midrange (mainstream) notebook offering.

Up Close and Personal with the Dell XPS L501x

    Right now, the "B+GR" is only listed on the 15.6 as an upgrade, while the 14" and 17" list WLED. Obviously, all WLED are not created equal, so unfortunately without testing I can't say how the other displays compare. We're working to get the other two models in for review, but we'll have to wait and see what happens.

    In order to get the GT435 GPU you HAVE to "upgrade" the CPU to a Core i7. I DO NOT WANT A Core i7, I want a Core i5. Yeah, let's reduce the clock speed by 1GHz then double the threads, yeah, that'll be great for gaming cause ALL games totally use 8 FUCKING THREADS!!!


    Seriously, WTF!? In what world is pairing a Core i5 with a GT435M and "compatibility issue". I fucking hate you Dell. Even when you start to do something right, you FUCK IT UP!

    I am angry out of my mind right now, I cannot believe they FORCE you to downgrade to a Core i7, fucking greedy bastards. That's NOT what I want. FTW!

    While that's true, your rant just made you come across as a complete retard...

    I originally noticed the 420M vs. 435M issue but the 435M is virtually just a factory-overclocked 420M anyway. You also don't get Optimus but I'd find it less 'forcing' you as there is some other underlying reason neither you nor I know about.
  • JarredWalton - Monday, November 15, 2010 - link

    Incidentally, while the i7 quad-core is lower clocked for the base speed, it has MUCH higher Turbo modes. So an i7-740QM runs at a base 1.73GHz but can Turbo as high as 2.93GHz when only one or two threads are active. The i5-460M in this system as reviewed runs at 2.53GHz base but can only Turbo as high as 2.80GHz.

    I'm betting you're thinking right now that the i7-740QM won't usually run anywhere near that 2.93GHz, but at least in my experience it does exactly that for many games. I'd go so far as to say that the only dual-core Arrandales that will clearly outperform a 740QM in games would be the i5-540M and i7-620M (and any higher clocked parts, obviously). But then, those cost just as much or more than the 740QM and in multithreaded loads they would still lose.

    As far as I'm concerned, the only real drawback to the quad-core upgrade is that removal of Optimus. 435M can definitely do Optimus (i.e. look at the L701x: BOOM! An XPS laptop with 435M and Optmimus!), but Dell is choosing to artificially require the CPU upgrade along with the GPU. Sandy Bridge should take care of the problem in the near future with IGP + quad-core + ~25% faster than Clarksfield/Arrandale at the same clocks. How long before we get SB + 445M Optimus? That's what I really want for the base L501x.

    Jarred, well you seemed to suggest there was no significant difference between the i5-460 and i7-740 in your review and then almost contradict this above.


    "...The higher base clock speed also puts it (ie i5-460M) within striking distance of the i7-720QM in multi-threaded tasks, so unless you really need every last ounce of multi-core power the dual-core i5-460M is a compelling alternative—and don't forget the loss of Optimus (and the price increase) that comes with moving to Clarksfield processors"
  • rorthron the wise - Tuesday, November 16, 2010 - link

    Have a look at your own post - the clue is in there!

    Sod it i'll tell ya - the i7-740 is quicker than the i7-720!!!
  • mopomoso - Tuesday, November 16, 2010 - link

    Haha! Teach me to post when I'm tired -:) Apologies to Jarred.

    I'm currently debating whether to buy a L501 now or wait for SB. Doesn't look like SB will bring any benefit thermally and will, at least with the duals, only provide a small increase in processing power.

    Plus it could easily take until February for SB XPS to ship.
  • blackrook - Monday, November 15, 2010 - link

    Isn't the 420m easily overclockable anyway?
  • rorthron the wise - Tuesday, November 16, 2010 - link

    I took delivery of an XPS 17 a couple of days ago; it kept crashing on me and now it won't start at all. When i try i get 6 beeps indicating a video card failure. It also came with a slight indentation on the right palm rest.

    I've got a full refund though, and i'm not too put off - it's just a bit inconvenient that i've now had to re-order, which means waiting another couple of weeks for a new machine.

    Hopefully this is not usual - doesn't Dell have a good reputation for reliability?
  • dgs - Tuesday, November 16, 2010 - link

    I can find various versions of the XPS in terms of CPU and screen size, but I can't find the model XPS L501x. More pertinently, I can't find any customization that will give me the 1080p screen that the review recommends. And that's the screen I want!

    I used to like Dell's website, long ago, but in recent years it's become so junked up that it's really hard to find what I want. Has anyone else been able to find it?
