Dell Latitude 7490 review Review

Written by 260Blog

These are the same chips that all the other laptop makers have access to, so the challenge Dell has is to make the 7490 stand out in other ways.

Dell uses the Latitude brand for a wide range of computing products, including laptops, tablets and Ultrabooks. They’re primarily aimed at business users, though potentially some of the cheaper devices might be of interest to students too.

Of these, the 7000 Series is an Ultrabook range and contains machines that have 12, 13 or 14-inch displays, and either 7th-gen Intel hardware, or, as with the new Latitude 7490 model reviewed here, 8th-gen processors and chipsets.

Price, availability and value

If you are willing to accept previous generation Intel technology and relatively little storage space, a Dell Latitude 7490 can be bought for as little £1,119 ($1,049).

However, if you’d like something with more current silicon inside and SSD storage, then the cost is £1,219 ($1,209). A flagship model, with a Core i7 CPU, 16GB of RAM and 512GB of storage is £1,529 ($2,039). Compared with what Lenovo, HP and Toshiba ask for similarly specified hardware, that price seems, like the whole 7490 series, very competitive.

Lenovo has the ThinkPad T480, although it doesn’t offer the same processor on that model (yet). It isn’t on the Lenovo X1 Carbon either, and that costs more for a lower spec.

On price, the HP EliteBook 1040 G4 is a good fit, even if it is still using Intel 7th-gen silicon on that model.

Asus has the excellent ZenBook 3 Deluxe UX490UA that can be found for a little more, but comes with a Core i7 class CPU, 16GB of RAM and double the storage of this review model.

As with most of the Dell range, customization options are available at the point of purchase, but with this series, the amount of RAM and storage is fixed for each model.

If you don’t like the combinations on offer, some memory and storage enhancements are possible by the end user.

Design 

For good or bad, the Latitude 7490 is made mostly of plastic.

Where others obfuscate the exact nature of their devices with paint and thin metal facings, Dell embraces plastic as its material of choice, and the surface finish achieved with it is admirable.

Poorly designed plastic machines flex and buckle, but the Latitude 7490 feels ridged and robust in all the critical areas, like the hinge, and where you place your palms to type.

The screen hinge is strong and allows the display to lie entirely flat. What value this might have on a machine that doesn’t have a touch display we’re unsure, but there might be some advantage we’ve overlooked. Some 7490 models do have touch displays, we’re told, although at the time of writing we couldn’t find any on the UK or US Dell sites.

Because of the 180-degree hinge travel, Dell kept the rear of the 7490 entirely clean, with no ports or vents whatsoever at the back. All the ports are on the sides, and the vents are underneath. Therefore, it’s worth bearing in mind that you should never place the machine on a soft surface where the vents could become blocked, as it would undoubtedly overheat.

The ports haven’t changed at all from the 7480 series, with triple USB 3.1 (Gen 1) Type-A ports and a single Thunderbolt 3 USB Type-C. There is also an RJ-45 Ethernet port, Smart Card slot, microSD card and SIM card receptacles.

The review machine didn’t have the LTE module to make use of the SIM slot, and as the standard for these isn’t a global one, the options for the LTE hardware will be different around the world.

Not providing a full-size SD card slot is mildly annoying, but adapters for Type-A USB ports don’t cost much.

The keyboard and trackpad are both better than we’d anticipated and exude the quality we’d expect from a more expensive brand. We especially liked the trackpad, which has keys at both top and bottom instead of using a flexible lower edge.

Given the amount of gutter space to the left and right of the keyboard, maybe a wider design could have been employed. That said, the keyboard design works well enough for typing, even with large hands.

Another strong point is the AU Optronics 14-inch IPS panel that’s a decent brightness and has a healthy color gamut. It also doesn’t use pulse-width modulation (PWM) to adjust brightness, with the negative impact that can have on eyesight.

Ergonomically, this is one of the smaller machines in this category, if only by a few millimeters. There are smaller machines, like the Lenovo X1 Carbon, but this device is certainly very portable.

As a replacement for the previous 7480 models, the new 7490 looks much the same from the outside, but has had a complete overhaul internally.

New Intel Kaby Lake R processors have gone beyond what designers could previously imagine with a 15W budget, and the review model had an Intel Core i5-8350U quad-core 1.7GHz (Turbo 3.6GHz) processor under the hood, which is the equal of many desktop CPUs.

Technically this chip can take 25W in a sprint, but also gear down to 10W should longevity be the primary objective.

The processor isn’t user upgradable, but it is possible to remove the base by undoing eight screws – then you can increase the amount of RAM and change the storage options.

Security

Business machines are more focused on security than consumer notebooks, and the Dell Latitude 7490 is well endowed to keep its contents safe.

The three main pieces of the security puzzle are a Smart Card reader, NFC sensor and fingerprint reader. Those who also want face recognition can add it as an option, but the review machine just had a simple 720p 2D camera.

Those who are inherently paranoid, and we all should be by now, will be concerned that the camera doesn’t have a privacy cover.

The fingerprint reader is a high-quality device that rarely misread in our tests. As this is likely to be the security mechanism most people will use, it’s a big plus point that it works reliably.

Specifications 

The Intel Core i5-8350U quad-core CPU is rapidly becoming the darling of laptop designers. It delivers much of the power that the Intel Core i7-8550U offers but has a lower unit cost and a less detrimental impact on battery life.

The 8GB of DDR4 system memory and 256GB of storage is enough to run, but heavy users might find that storage gets somewhat snug after a few months use.

The Dell policy on memory and storage is that these things aren’t generally adjustable in the customization part of the purchase path, and therefore if you want more, then you need to choose a different model. Or, get a screwdriver out and source the parts for a user upgrade.

Usage and performance 

Many laptop makers are offering machines with the slower Core i5-8250U that runs at 1.6GHz, but less have the Core i5-8350U (1.7GHz) used in this machine.

That’s only 100MHz quicker, or 200MHz with Turbo, but this machine performs much better in many respects. It breezes through most office tasks, and the SATA SSD allows the laptop to wake rapidly from sleep and be ready to do something immediately.

The only place this device doesn’t shine is when doing 3D graphics work, because the UHD Graphics 620 GPU is something of a slug at that job.

Combining the Thunderbolt and HDMI ports, it is possible to drive three displays simultaneously with this GPU. Just don’t expect much to happen rapidly on all of them if you do this, as only one will be GPU accelerated.

Without a discrete GPU this hardware isn’t of interest to a designer or gamer, but for general business use, it is an excellent workhorse.

The benchmark scores reveal that there is only one part holding back this Dell notebook, and that’s the SATA-based SSD. Compared with a machine using a conventional hard drive it is flying, but any drive-related scores could be improved by using an NVMe solution.

Dell used an Intel 545s M.2 SATA drive in the review hardware, and on paper, it looks fine. But in some of our writing tests, it didn’t perform that well, and the IOPS it delivers don’t compare favorably with those you’d get from a Corsair or Western Digital.

The CPU-related tasks all hit great numbers, and not far from what the Core i7-8550U-based machines are capable of. As they share an identical Intel UHD Graphics 620 GPU, the results for anything graphical are almost the same.

That’s the other weakness of this design, but it shares this limitation with every Intel 8th-gen machine of whatever specification.

Using a Datacolor Spyder5 calibrator, we analyzed the screen and found that it could display 99% of the sRGB gamut and 75% of AdobeRGB. Those are good numbers for a portable device, even if they’re not high enough for professional color work.

Battery life 

Portable computers are often defined by their power resources and management. And the battery tests we did on the Latitude 7490 underlined what an efficient and streamlined package it is where power is concerned.

Using the PCMark08 Work test, we ran the machine at maximum speed for 7 hours 51 minutes, and configured for longevity, the laptop managed an impressive 10 hours 51 minutes.

What substantially helps this model is the 60WHr battery with a whopping 7500mAh, at least 20% more capacity than most competitive products offer. With this capacity, running all day including additional time on a commute is both realistic and practical.

There is only one aspect of the machine that we don’t care for, and that’s the Dell proprietary PSU. It might have a nice glowing end so that you can find it in the darkest hotel room, but this machine has a USB Type-C port, and a Type-C charger would have been ideal.

A peek inside

We can’t resist opening up machines, even if the makers occasionally aren’t keen.

Inside the 7490 is a very refined space with almost no room for anything extra, except an unused DDR SODIMM module slot, and a PCIe slot for the optional LTE modem.

There isn’t room for a conventional 2.5-inch SATA device, though the M.2 slot will take a bigger module, and it is also compatible with NVMe PCIe M.2 drives.

For those who want to go inside the laptop, removing the base is a very straightforward exercise that only requires the undoing of eight screws. A nice touch is that the plastic base panel retains the screws, so you can’t misplace them once the cover is taken off.

Final verdict 

There is so much to like in the Latitude 7490, despite it being a very derivative design from what came before. The new Intel silicon performs admirably, and this Dell machine has enough battery longevity so it won’t disappoint those who like to work on the move.

In short, the Latitude 7490 ticks more boxes than we have the right to expect at this price.
