Dell Precision M3800 Overvie

July 14, 2018

Design & Build Quality

The Precision M3800’s design has more in common with Dell’s high-end XPS consumer laptops than bulkier workstations: the lid and edges are clad in brushed aluminium, and the interior, base and sides are all finished with soft-touch chargeur acer aspire switch 10/chargeur acer switch 10/chargeur acer aspire switch 10 sw5 012/acer aspire switch 10 chargeur/acer switch 10 chargeur carbon fibre laid over a strong aluminium frame.

The high-quality materials mesh well with the clean lines and simple curves to make a great-looking laptop, and build quality is impressive. There’s no noticeable give in the wrist-rest, and the base feels similarly sturdy. The screen is a little weaker, and we noticed distortion on the desktop when we prodded its rear, but that’s the only issue’it’s not surprising, given the panel is only 4mm thick. It’s very strong, and only the MacBook Pro is sturdier. The right-hand side houses single USB 3 and USB 2 ports alongside a card reader, and the left-hand edge serves up two more USB 3 ports, an HDMI output, a headphone jack and a mini-DisplayPort connection.

The only thing missing is Gigabit Ethernet, although a chargeur tablette samsung galaxy note 10.1/chargeur pour tablette samsung galaxy note 10.1/chargeur samsung tablette galaxy note 10.1/chargeur samsung galaxy note 10.1 gt n8010

USB adapter is included. Connectivity elsewhere is good, with dual-band 802.11ac wireless a sensible, future-proofed addition alongside Bluetooth 4.0. There’s no room for mobile broadband, perhaps because these slots are usually found beneath removable batteries’a feature the Dell lacks.

Rounding out the keyboard

Another trait the M3800 retains from older XPS designs is a compact island-style keyboard with rounded, almost toy-like keys. They provide reasonable travel and the layout is adequately spacious, but the key caps themselves could be better. Their texture doesn’t match the expensive feel of the notebook’s other materials. This didn’t slow are tchargeur asus adp 90yd b/adp 90yd b/ac adapter asus adp 90yd b/asus adp 90yd b/adp 90yd b asus yping, though, or result in any extra errors.Backlighting is standard. Only two brightness levels are offered, one of which was actually too bright for use in a typical low-light situation, and seems to exist only to show off the backlit keyboard to friends. The second, tamer setting was thankfully usable, and there’s only moderate light-leak around the key caps.We enjoyed the touchpad, which is about four inches wide and three inches deep. It has a somewhat grippy surface that adds texture to the experience and multi-touch inputs worked well. The integrated left/right mouse buttons activated stiffly, but tap-to-click was a perfectly fine substitute, and we generally preferred it to attempting a ???real??à click.


The system comes with a quad-core Intel Core i7-4712HQ processor and ISV-certified Nvidia Quadro K1100M discrete graphics. It scored 2,664 points on the PCMark 8 Work Conventional test, so it’s sufficiently speedy on day-to-day tasks. chargeur asus exa1208eh/exa1208eh/ac adapter asus exa1208eh/chargeur exa1208eh/ac adapter exa1208eh It took only 1 minute 19 seconds to complete the Handbrake video encoding test and 3:30 to complete the Adobe Photoshop CS6 test. Both times are very close to those of other high-end laptops and mobile workstations, like the Apple MacBook Pro (1:17 on Handbrake; 3:25 on CS6) and the Lenovo W540 (1:20 on Handbrake; 3:18 on CS6). Its score of 599 points on CineBench puts it behind the Toshiba P50T-BST2N01 (611 points) and the Lenovo W540 (637).While you likely won’t be playing games on the M3800, its 3D gaming scores are adequate for a professional workstation. It returned frame rates of 22 frames per second (fps) on Heaven and 29fps on Valley, both at Medium-quality settings. That’s marginally better than the integrated Iris Pro graphics in the Apple MacBook Pro 15-inch Retina (22fps on Heaven; 23fps on Valley), though the Lenovo W540 (30fps on Heaven; 42fps on Valley) was measurably faster on the tests. Thus, the M3800 has enough power to qualify as a mobile workstation, though others in its class are marginally faster.

Battery life was a mixed bag in testing. The system lasted 4 hours 53 minutes on our battery rundown test. That’s an hour less than the Lenovo W540 and the previous iteration of the M3800. The class leader remains the Apple MacBook Pro, which lasted almost nine hours. However, 5 hours is still better than the Dell Precision M2800 (4:26) and the Toshiba P50T-BST2N01 (2:45).Overall, this year’s Dell Precision M3800 is an improvement over the previous iteration in terms of connectivity, price, and screen resolution. chargeur asus x205ta/chargeur asus eeebook x205ta/asus x205ta chargeur/asus eeebook x205ta chargeur Its battery life is not as long as last year’s M3800, but that’s to be expected, given the higher-resolution screen of the new model. If you absolutely need the extra real estate of a 4K screen, and you’re willing to keep the AC adapter handy, the new M3800 is a good pick. The Lenovo ThinkPad W540 remains our Editors’ Choice mobile workstation, thanks to its built-in color calibrator, longer battery life (and replaceable battery), easier expandability, and a slightly less-expensive price tag.

4K done right

Our M3800 evaluation unit arrived with the optional 4K touchscreen. It offered impressive image quality from the start, with good contrast and strong chargeur bose soundlink mini/chargeur bose mini soundlink/chargeur enceinte bose soundlink mini colors, traits that served it well as we viewed a variety of 1080p, 1440p and 4K content. While the panel’s glossy coat at times was a bother, in general the backlight was able to overcome glare. Of course, like most such screens, it looked great in a dark setting, where glare was not a problem.

Testing revealed numbers that backed up our initial impressions. The contrast ratio, which reached 840:1 at maximum brightness and 800:1 at half, was the best we’ve ever recorded from a laptop. Apple’s MacBook Pro 13 with Retina hits 770:1, the Asus Zenbook NX500 manages 760:1, and the Acer Aspire V15 Nitro Edition with 4K panel came in at 690:1.Maximum brightness soared to 383 lux and color accuracy managed an average error of less than one, making the M3800 only the second laptop (after the Zenbook NX500) to offer such a result. That’s important because an error below one is generally unnoticeable chargeur asus r510c/asus r510c chargeur/chargeur asus r510cc/chargeur pc asus r510c/alimentation asus r510c to the human eye. However, this is still a standard gamut display, reaching 99 percent of sRGB but only 74 percent of AdobeRGB. That’s on par with most notebooks, but the Zenbook NX500’s wide-gamut display hit 96 percent of AdobeRGB, providing additional colors that digital artists may be interested in using.

We did occasionally run into 4K scaling issues. Spread across 15.6 diagonal inches, the resolution translates to about 280 pixels per inch, which is about as dense as modern Windows laptops get. Older programs not built with high resolutions in mind were an issue, as they looked fuzzy if they rendered at a readable size, or comically small if they didn’t.

The built-in speakers were strong, delivering chargeur surface 2/chargeur microsoft surface 2/chargeur tablette surface 2/alimentation surface 2/chargeur tablette microsoft surface 2 enough oomph to fill a large room with sound. Some bass was available, which means the M3800 doesn’t sound as flat and tinny as most laptops. On the downside, the sound system was at times so loud it shook the laptop’s enclosure, creating an unpleasant buzz as components and panels vibrate.


With tumbleweed blowing through the streets that should have been touting new Intel mobile quad-core processors from every stall, Dell is also forced to use a main processor from a series that’s two long years old. Replacing the 2.2 GHz Intel Core i7-4702HQ is a 2.3 GHz Core i7-4712HQ, a tiny 0.1 GHz clock speed increase, and uses the same Intel HD Graphics 4600 as the low-power graphics processor.

For best graphical performance, there is also the same Nvidia Quadro K1100M GPU, keeping the 2 GB GDDR5 video memory specification from before.

Main memory stays at 16 GB, two 8 GB DDR3 cards running at 1600 MHz. And storage comprises the same capacity 256 GB mSATA SSD, although our new sample has a Samsung SM841N flash drive, effectively an OEM version of the Samsung 840 Pro SSD.

This replaces a Lite-On (Plextor) mSATA SSD. And where the last generation also included an additional basic 2.5-inch SATA hard disk for bulk storage, this new model was supplied with just the single flash drive. That could explain why this new model weighed 1.95 kg, against the 2.04 kg of yore.For network connections, there is no built-in ethernet although a USB 3.0-to-gigabit-ethernet adaptor is included in the box. For wireless links there’s the usual Bluetooth 4.0, and a two-stream 11ac Wi-Fi adaptor from Intel.

The keyboard is solid enough for sustained typing, notably omitting the right-hand numberpad that most 15-inch Windows laptops include chargeur surface pro 2/alimentation surface pro 2/surface pro 2 chargeur/chargeur surface pro 2 boulanger to help fill the deck space. Instead Dell has copied the plan of the MacBook Pro again, usefully allowing the trackpad to be correctly centred on the top deck rather than uncomfortably offset to the left.

The trackpad is buttonless, smooth and black, with almost the same rubbery texture as the top deck. In use it proved suitably precise to allow easy navigation and mouse steering. Two-finger scrolling is of the ??natural’ type pioneered by Apple by default, where the fingers follow the direction of intended movement.

Stereo speakers are hidden below the front edge of the chassis, and are perhaps the loudest we’ve heard on any laptop when turned up. More pertinently, the sound quality is not too bad either, showing clear treble extension and less of the chargeur surface 3/chargeur microsoft surface 3/surface 3 chargeur/alimentation surface 3 grit and tinniness that usual comes with laptop territory. Importantly the midband is relatively clean and intelligible for good vocal diction.

The display has been increased in resolution from the original 3200 x 1600 pixels, to 3840 x 2160. You could look at these as ??quad 1600 x 900′ and ??quad 1920 x 1080′ screens respectively. Again this is an IGZO technology panel made by Sharp, using indium, gallium and zinc oxide to form the thin-film transistor matrix.

In size, the Precision M3800 15.6-inch display is smaller than the 15.4-inch display found on the MacBook Pro, since Dell has selected a narrow 16:9 aspect-ratio widescreen designed for consumer products. Mounted in its bezel, there is Dell XPS M170 M1710 Slim Charger the box, the interface is very clean and sharp, with precisely detail typography. There is the usual problems with Windows programs though, some of which do not respect the enlargement so appear minute on-screen; or other programs that do render at the correct size but with fuzzy text and windows.

In use we found the internal cooling fans were not as loud as we remembered from the first generation model. Handling of the M3800 is not as comfortable as it could be, with the weight distributed toward the hinge from the heavy touchscreen CP500588-01 Fujitsu 65W Charger can’t keep the quad-core processor and 4K display powered far beyond four hours in our Web browsing benchmark. Buyers who need endurance should stick with the base, 1080p panel.

We also think it’s near time for a design and style update, as the M3800’s aging chassis, while still unique, is starting to show its age. Yet it remains sturdy and feels luxurious enough to support the system’s rather intimidating $2,250 price.
