Dell XPS 15 L502x: Now with Sandy Bridge
by Jarred Walton on April 20, 2011 1:10 AM ESTDell XPS 15 L502x: Tweaking the Formula
Late last year, we finally got a laptop with very few compromises that we could look to as the king of the mainstream market. That laptop was Dell’s XPS 15 L501x; it took a balanced approach to performance, battery life, and portability, with a great display upgrade as a bonus offering. Perhaps more important was you could get all of the important features and still pay less than $1000. It was only natural—nay, inevitable—that Dell would update the XPS line with Sandy Bridge processors, and that’s what we have for review today with the XPS 15 L502x. The graphics have also received a minor update to NVIDIA’s 500M line, though the 400M and 500M are basically fraternal twins.
We won’t spend a lot of time discussing the nuances of the build, as very little has changed relative to the original XPS 15. If you want more information on build quality, the keyboard, etc. we refer you back to our earlier write up. The short summary is that the build quality is still good, but it’s not at the level of something like a Dell Latitude. Dell uses a magnesium alloy frame in the XPS, but the top and bottom are still plastic. Perhaps the bigger issue some will have is with the curves; love it or hate it, the curves are here to stay for the time being. We’ll have a bit more to discuss in a minute, but first let’s start with our usual spec table. The following table lists the available options for the XPS 15, with our review configuration components bolded where applicable.

We received a moderately upgraded version of the L502x this time around. The base model starts at $800 and you can still add the nice 1080p LCD for $150, so you’re still able to get a nice display for under $1000, but outside of Quick Sync the Core i5-2410M isn’t a major upgrade from the older i5-460M and the same can be said of the GT 525M vs. GT 420M. Basically, it’s better, and it’s about the same price, but if you already have the L501x there’s no need to upgrade to dual-core Sandy Bridge. Quad-core Sandy Bridge is a different story, as we’ll see in the benchmarks; Dell shipped the cheapest of the quad-core options, the i7-2630QM.
Along with the CPU upgrade, we’ve got the GT 540M, which is a faster clocked version of the 420M/425M/435M/525M/etc. The old XPS 15 came with a GT 420M by default, which clocks in at 500/1000MHz core/shaders and 1600MHz on the RAM, so the GT 540M has 34% more theoretical computational power and 12.5% more memory bandwidth, plus twice the RAM for good measure. The base model L502x comes with the GT 525M, which is clocked at 600/1200MHz core/shaders, so the 540M is only about 12% faster on the core but has the same memory bandwidth. Depending on the bottleneck, then, the new system should be 10-35% faster than the L501x in games, and potentially more than twice as fast in CPU calculations.
Other upgrades on the test system include 8GB RAM, a 9-cell battery (we still have the smaller 6-cell around as well), and this is the first time we’ve seen a 750GB 7200RPM 2.5” hard drive. Western Digital’s Scorpio Black is king of the 2.5” HDD hill, but unfortunately it’s also a far cry from matching even moderate SSDs. What it lacks in raw performance it makes up for with capacity, and with the increase in areal density the 750GB drive should outperform older 500GB 2.5” drives. Finally, besides the backlit keyboard, Dell also included the 1080p LCD, a TV tuner, and Bluetooth 3.0. The final tally for our test configuration is a much heftier $1425 at the time of writing. Is it worth it? As with so many other things in life, the answer is a nebulous “it depends”. Let’s discuss things a bit more before we get to the benchmarks.

seem to accentuate any flaws or slight color vairiances to me.i definately prefer matte so that i don't have to deal with the glare, but i noticed that anti-glare fliters, or matte finishes tend to exaserbate light bleeding in spots and so on.
i noticed this most on TN screens that have been used for a couple of years and are starting to get a little worn out; the glossy finish seems to hide the deterioration to me.
has anyone else noticed this, or do i have a unique situation/i am going crazy?

The one issue I have with matte is that if you happen to brush against it with an object you can leave a "scar" -- not a scratch, but just a mark in the matte finish. If you have a poorly built laptop where the keyboard or palm rest happens to press against the LCD, that can also cause marking -- on glossy as well, but it's more noticeable on matte. Heck, I have a "scar" on my 30" 3007WFP that happened when I was packing for a move. Yeah, ouch! The old Dell Studio XPS 16 had the other issue, with keyboard marks showing up on the edge-to-edge display cover.Anyway, having seen both the Clevo P150HM/151HM and the XPS 15 panels side by side, I'd definitely take the matte and run that risk.

Jarred,I have a Dell 2405 FPW with matte finish. Spent around £800 on it back in the day but don't regret it a bit as it's still a contender - rare even now to find 24" with matte IPS that can go portrait and has a USB hub and card readers built in. Anyhoo, I digress... I also got scars on it once or twice and I couldn't for the life of me 'wipe' them away but if you google around you can find solutions...
Amazingly, I found using a clean (try new) white or colourless rubber on the screen and rubbing gently in the direction of the scar worked. Wipe before and after with a lint free micro-fibre cloth and just a teensy bit of water. It literally made the scar disappear and the monitor looks as new again. I sh1t you not - worth a try.

I've found quite the opposite. My matte displays seem to hold up much better than the glossy. The glossy ones seem to pick up scratches, marks and smudges very easily and they show horribly. The matte finish tends to disguise the little things.AmdInside - Wednesday, April 20, 2011 - link
I bought the L502x and love it. One great thing about Optimus is that since the Intel graphics is still used for 2D, Intel Quick Sync is possible with this laptop. It is amazing how fast it can convert video for a laptop.I guess my main complaint is that I preferred the previous generation keys better over the newer smaller softer keys. Dell has regular sales on XPS laptops which really brings down the cost of this laptop. I got a fully loaded Dell XPS 15 L502x for around $1300 after taxes. Just love love love the 1080p screen.
Oh, and I personally am not a big fan of super thin laptops. They just don't feel right when they are on my lap. I like my keyboard to be raised a little so the thicker body of the l502x suits me just fine. I wish Dell hadn't dropped the 14" model as I would have bought that if it was still available with Sandy Bridge for portability but the 15" is fine.

I had a 17" Dell years ago with a 1080p screen and a 7900GT Go. It did OK, but ultimately, I don't think I would ever buy another 1080p laptop without a high end GPU. If the L502X had a higher GPU option, it would be perfect! I would probably order this laptop with the 768p screen and upgrade to the 540 and play games with max settings at native resolution.aneuwahl - Wednesday, April 20, 2011 - link
Hello,there is a puzzling thread on Dell's support forum here
http://en.community.dell.com/support-forums/laptop...
about an unsolved problem regarding the USB3.0 ports. They seem to fail randomly becoming completely inactive till next reboot.
I'm curious if during the test anything like that was noticed.
I've just bought a L702x and I have the same problem. Dell replaced my motherboard (not the USB3.0 daughterboard), but the issue - with reduced occurency - is still there.

Is it possible they're going into a power saving state and not coming out of it? I actually don't have any USB3 devices on hand, so I didn't encounter this, but I should be getting something soon. Let me get back to you....jcannon1018 - Wednesday, April 20, 2011 - link
Supposedly, under all programs there is a folder for the usb 3.0 controller and clicking on it will bring up a settings panel for the controller. On that panel there is a disable power management function, checking apparently resolves the issue of the ports becoming unresponsive. I thought that sandy bridge had native support though?
