Dell Precision M6700 Notebook Review: The Enterprise Split
by Dustin Sklavos on December 12, 2012 7:43 PM ESTDisplay Quality
For whatever reason, ColorEyes Display Pro just refuses to cooperate with the LG Philips IPS panel Dell uses in their Precision M6700 unless you calibrate at a Gamma of 1.8 instead of 2.2. This produces a fine image, but it visibly loses a lot of the pop, saturation, and gamut of the display's default calibrations. Note that Dell includes PremierColor software that actually allows you to switch between different color gamuts, and it's a welcome feature.
The measurements are generally solid, with the PremierColor display at least offering a solid sRGB color gamut. Unfortunately due to issues with ColorEyes Display Pro I'm unable to confirm whether or not it can truly produce the entire AdobeRGB1998 color gamut like Dell claims it can, but honestly I believe it can.
Frankly it's a beautiful display and anecdotally it's on par with the DreamColor display-equipped EliteBook I currently have in house for testing, maybe even a step up due to Dell's PremierColor software which allows you to not only choose the color gamut you want to work with, but will even detect applications and adjust accordingly.
Battery Life
Where these workstations are still lagging substantially behind their consumer counterparts is in their power management technology. NVIDIA's Optimus has been thriving for years now on consumer GPUs, but Quadro chips still don't benefit from it. AMD just got Enduro working well on their mobile GPUs, but it's not functioning on FirePro chips either. As a result, the Dell Precision M6700 is forced to employ an oversized battery to compensate.
Update: Mea culpa. While Optimus is functional on NVIDIA's mobile Quadro GPUs, the use of a 10-bit IPS panel (along with either a 120Hz panel or touchscreen) precludes it due to bandwidth limitations. As a result, the M6700's battery life is going to be substantially lower with the PremierColor display, but I would actually expect M6700s with a standard TN panel to produce running time closer to the Alienware M17x R4, which has a smaller battery but similar silicon.
Optimus-enabled notebooks are able to get at least a little more mileage. The M6700's battery life actually isn't that bad given that it's a workstation notebook, owing at least somewhat to both Ivy Bridge's frugal power consumption and Kepler's superior idle power compared to Fermi.
Heat and Noise
Thankfully, the Dell Precision M6700's beefy cooling system keeps the notebook running both reasonably cool and quiet. Keep in mind that we're working with a combined TDP of roughly 155W on the CPU and GPU in this system when you take a look at the thermals below.
The CPU runs nice and toasty, but the M6700 is actually very effective at keeping the K5000M cool. Noise levels are very good, with the notebook basically inaudible at idle and fan noise being a low, quiet whoosh under load.

Manufacturers are able to produce significantly moer powerful performances for desktop platforms. The article above already shows a single Quadro K5000 in a Lenovo D30 outperforming the notebook. Dell will be happy to give you dual K5000s in a precision T7600. nVidia will happily tell you that even 4 K5000s are an option with Quadro Sync.If anybody will send this kind of 12k$ to 20k$ Workstation to Anandtech for testing is a whole different question.
Also, AMDs 8-cores are not the desktop counterpart to this notebook. Think quad-socket 16-cores instead.

Anandtech, can you all figure out why Dell can't get any 15.6" IPS displays for the M4700? I just got one right after they took the IPS option off of their website, but the option is still everywhere on their support documentation. It really ticks me off that we just payed a ton of money for one of these, and I can't return it for one with a proper display. It would be awesome if you could blow the lid off of whatever sourcing issues they are having, since their customer service won't say anything at all.Alvern - Thursday, December 13, 2012 - link
Somebody on Notebook Review said that Dell couldn't get quality screens from their suppliersilenceisgold - Thursday, December 13, 2012 - link
ok, that's great. but why? LG (which I believe is the supplier) has been making IPS screens now for ages, what's going on now that would change that?And why did they yank the option without some sort of notification on their site. The support manual says there should be a 3D option too; not there as well.

The M4700 had corner tint issues on the IPS display which, we assume, is what led to Dell dropping that option.twtech - Thursday, December 13, 2012 - link
Instead of trying to squeeze the keypad in, I'd prefer they just skipped it, and used the space to provide desktop-size keys. I actually don't even use a keypad on my desktop at work. As a programmer, I frequently type in numbers, but they're almost always mixed in with letters and symbols.I realize that some people do use the keypad, and I'm not saying that all laptops should be built that way, but I would like to have the option to buy a Windows laptop with that configuration from someone.

Alternating my gaze between a Microsoft Natural Keyboard and my M4700. Can't really see the difference in the key sizes.Tech-Curious - Sunday, December 16, 2012 - link
Are the notebook's keys slightly closer together? That's the only thing that leaps to mind when I read twtech's complaint. My 17" laptop has a full keyboard similar to the Dell's, and it does feel significantly more cramped, even disregarding the placement of the arrow/numpad keys.The keys are the same size, though. You're right about that.

As a user of the M6700 and MBP, I have to say most of the criticisms not to be founded.The case and build quality both are top notch, the palm rest has been switched to a pleasant soft touch rubberized. It is also extremely user serviceable all the way down to using MXM standard GPUs and socketed processors.
I don't think the hardware options can be knocked in any way, full Ivy Bridge processor options and a wide range of GPU, storage, display, and connectivity options.
Personally I don't have the IPS screen (I prefer the battery life of Optimus 7+hours), but from what I've read on the notebookreview.com forums the Dell IPS screen when properly calibrated has a larger gamut than the HP screen.
I appreciate an honest review that points out the potential flaws, but this review seemed to immediately counter any glimmer of positively with some sort of comment about disappointment that gives a 8.5/10 laptop a 3/10 perception. Any machine has it's negatives but it really is not a fair portrayal of an excellent machine.
Here are some prime nbr threads:

I wish the reviewers would be harshly critical of both the Dell and the HP mobile workstations. Actually, all 17" machines for that matter. But, especially the Dell and the HP, since we all know what they purport to be:They are supposed to be the ultimate in mobile computing and desktop replacement.
I get very hopeful each time they offer a new model... but, upon closer scrutiny each 'new' model looks like a bowl of yesterday's runny oatmeal mixed with a few chunks of fresh fruit.
It'll do, but its not an ideal representation of what could be currently had if someone would bother to do the cooking they get paid for...
...and we all know it.
