What is the Dell Precision M3800 (2015)?

When we reviewed the original Precision M3800 at the start of 2014, we concluded that it was one of the MacBook Pro's only valid rivals – but that was 18 months ago, and in the laptop world that’s a lifetime.

Dell has updated the M3800 with a 4K screen and better internals, but its rivals have been busy too. The MacBook Pro features a Force Touch pad, and the HP ZBook 15 has tried to steal the Precision’s workstation thunder by including an array of office-friendly features.

Dell Precision M3800 (2015) – Design

On the outside, the M3800 hasn’t changed. Some may say that’s lazy but, given the Precision’s sheer class, I'm not fussed. The aluminium lid still looks stylish and feels fantastic, and the interior and base are still made from the smart, soft-touch carbon fibre of the original.

The little touches are still similarly impressive. The bevelled edges add class, there’s a five-light battery indicator, and the serial codes and logos are hidden beneath a smart metal panel on the underside. For a little added pizzazz, Dell has even left the weave visible on the base’s carbon fibre.

There wasn’t much need to put the Precision on a diet. The M3800’s 1.8kg weight and 19mm thickness are close to the MacBook Pro, and far slimmer than the HP ZBook 15, which is a kilo heavier and twice as thick. However, in fairness to the HP, it’s a more traditional powerhouse office notebook.

Build quality is excellent, with no budge in the base and only slight movement in the lid when it's pressed. Getting inside is possible, if tricky – you’ll need to remove around 12 screws – and the memory, storage, wireless chip and battery are all accessible for upgrades. There’s no room to add extra, however.

The M3800, then, remains one of the slickest-looking workstation laptops around. Like the MacBook, its aesthetics are good enough to easily withstand a couple of years without a major update.

Dell Precision M3800 (2015) – Features

The 15in 4K screen is the biggest component change then, but other parts have received a minor update too. The 2.2GHz Core i7-4702HQ processor has been replaced by a 2.3GHz i7-4712HQ model, and the Lite-On SSD has been replaced by a Samsung SM841n model that should offer more speed.

We don’t sniff at spec boosts, but the minor processing bump continues to rely on old Haswell technology. That’s the same CPU generation featured in the MacBook and HP, but it remains a tad disappointing when Broadwell silicon is now more common and Skylake is just round the corner. Dell hasn’t been able to confirm if the M3800 will be upgraded any time soon.

Elsewhere, it’s business as usual: Nvidia’s Quadro K1100M graphics core goes beyond integrated GPUs and comes with ISV certification, so it’s guaranteed to work with business software.

Connectivity is average. There’s dual-band 802.11ac wireless and Bluetooth 4.0, but Gigabit Ethernet works only with the supplied USB adapter. This is quite an omission for a workstation laptop. Also included are three USB 3 connectors, a Thunderbolt port and an HDMI output, as well as an SD card slot and a single headphone jack.

The Dell’s specifications are fine for a high-end work laptop, with its 4K screen, powerful components and reasonable connectivity handling most work tasks without complaint. In some areas, though, it’s still outgunned.

The MacBook Pro has PCI-based Flash storage, its Force Touch trackpad and a newer processor. And HP’s ZBook weighs more, but it’s got military-grade testing, a Blu-ray drive, ExpressCard, Secure Digital ports and a fingerprint reader, all of which are important for business machines.

We’ve reviewed the most potent M3800, but other models are available. A version that costs £1,559 has a 1080p screen, 8GB of memory and a 500GB hard disk. Dell also sells a “build your own” model that comes with multiple memory and storage configurations and a larger battery.

There are also multiple OS options. Our sample comes with Windows 7 Professional, but Windows 8.1 Pro and even Ubuntu 14.04 are listed on Dell’s website. Windows 10 isn’t there yet as a preinstalled option but, with free upgrades available, getting Microsoft’s latest OS is a formality.

A variety of data protection options are available alongside accidental damage protection, anti-theft options and recovery tools. The standard specification comes with a basic one-year warranty, which is fine, and that can be extended for up to five years.

Really? Blu-ray drives are important for business machines? I must have been living in a cave for the past few years then...

The lack of a numberpad is a blessing for those who can type and hate typing at an angle. You can sit facing the center of the screen rather than the left-hand third thereof...

Good laptop ruined by a couple of minor design flaws which cripple it to the point of me hating it. Such a shame. Its beautifully thin, but so thin it twists when on your lap - causing the trackpad to left click without you touching it, or preventing you clicking when you try! They also removed dedicated home/end keys which for a professional laptop is unforgivable (pause/break and windows context menu key also culled - all of which are useful to developers) - the sad thing is there was plenty of space to include a full numeric keypad if they wanted! The drivers are also quite buggy - particularly Intel's wifi driver and the touch drivers - both frequently fail when resuming from sleep. Aside from these issues it would be my ideal laptop - lightweight, fast, nice display, good battery life.

As a laptop, this has a great spec. but with a couple of major flaws. 1) Standard battery life is *appalling*. I cannot get more than 1.5 hours when using wifi. 2) Scroll pad is terrible. I use Linux, and the pad needs a whole load of custom configuration. No 3rd mouse button (or even 2nd button lol) makes this way more hassle than it needs to be. They're just copying Apple. In fact the pad is essentially useless for anything other than Internet surfing. On the plus side, the screen is very nice, and the touch can be useful. Weight isn't terrible considering the size of thing. The DisplayLink "docker" - its not a docking station in the historical sense - is a pain to get going under Linux. I had it working but multiscreen output broke after some updates and a couple of hours of work later, remained broken, so I gave up. Now I just plug a screen directly into the HDMI socket on the laptop itself. Really this is not good enough for such an expensive machine. Perhaps if you run Ubuntu, or Windows, some of these issues are not so bad.
