Dell Latitude 7440 laptop review: Beating the Latitude 9440 in some key areas
The Dell Latitude 7440 clamshell succeeds last year's Latitude 7430 by introducing a brand new 16:10 chassis design alongside the usual internal updates to 13th gen Intel Raptor Lake-U CPUs. The Latitude 7000 series is home to Dell's upper midrange business models in contrast to the flagship Latitude 9000 series and more budget-oriented Latitude 3000 and 5000 series.
Our unit in review is a middle configuration with the Core i5-1345U vPro CPU, 16 GB LPDDR5 RAM, and QHD+ 2560 x 1600 matte touchscreen for approximately $1900 USD. Other options include the Core i5-1335U or Core i7-1365U with double the RAM or a lower resolution 1200p display.
Competitors in this space include other 14-inch business-centric subnotebooks like the HP ProBook 440 G9, Lenovo ThinkPad E14 G4, MSI Prestige 14, or the Asus ExpertBook B3 Flip. A 13-inch version of the model exists called the Latitude 7340 while the 14-inch 2-in-1 version is called the Latitude 7440 2-in-1.

Case — Heavier Aluminum Or Lighter Magnesium?
Two chassis options exist: the bright gray aluminum skeleton or the darker magnesium skeleton. The former is more rigid at the cost of a heavier weight (+200 g), but both are otherwise very nearly the same when it comes to dimensions. Our specific review unit is the magnesium version which is definitely not as rigid as other subnotebooks like the HP Spectre x360 14 or the ThinkPad Titanium. Attempting to twist the base or lid, for example, would result in audibly more creaking.
Furthermore, we can notice a fault in the design of the Latitude 7440. The two front corners of the bottom panel each have screws to hold them in place, but the center of the edge does not. Thus, the front edge of the bottom panel has a tendency to pop out and leave a noticeable gap between the materials. A simple screw here would have easily solved this problem.
The new model is squarer than its predecessor due to the move to 16:10 from the previous 16:9. It's also a hair thicker than before by about half a millimeter. Many consumer-based Ultrabooks like the XPS 13, LG Gram 14, or Galaxy Book3 Pro 14 are noticeably thinner but with fewer integrated features.
Connectivity — No More SD Reader
Port positioning has changed from the Latitude 7420 potentially for the worse. The two USB-C ports, for example, are now both along the left edge instead of having one port on each side. This means that the Latitude 7440 can only be charged from its left side which may not be optimal for some office spaces.
Competing models like the ProBook 440 G9 or ThinkPad E14 G4 each come with integrated RJ-45 ports unlike on our Dell, but they have fewer USB-C ports.
Communication
An Intel AX211 comes standard for Wi-Fi 6E and Bluetooth 5.3 connectivity. Transfer rates would be reliable and stable when paired to our Asus AXE11000 6GHz network.
The Intel 5000 DW5931 is an optional upgrade for 5G WWAN connectivity.

Webcam — Optional 5 MP
Whereas last year's Latitude 7430 was limited to 1 MP and 2 MP camera options, the Latitude 7440 includes a 2 MP camera as standard with a new option to upgrade to 5 MP. Images are noticeably sharper but slightly overexposed. Many HP Elite laptops offer 5 MP webcams as well.
A privacy shutter comes standard while IR is optional.
Maintenance
The bottom panel requires only a Phillips screwdriver to remove. Users have direct access to the removable M.2 WAN and M.2 SSD modules while the RAM modules are soldered.
Accessories And Warranty
There are no extras in the box other than the AC adapter and paperwork. A three-year manufacturer warranty with onsite service comes standard.
Input Devices — Wider Clickpad Than Before
Keyboard
Touchpad
The clickpad is wider than the one on the older Latitude 7420 (13.4 x 7.3 cm) with smooth gliding properties no matter the cursor speed. Feedback when clicking is firmer and with deeper travel than the clickpads on most other laptops including the XPS 13 series or Asus Zenbook series. It's certainly easier to use than the horrid clickpad on the Latitude 9440.
Display — 1200p and 1600p Touchscreen Options
The AU Optronics B140QAX panel on the Latitude 7440 is the first to appear in our database. It features all the best attributes of the Chi Mei CHF07 140HCG 1080p panel on the older Latitude 7420 like the high contrast ratio and full sRGB coverage but at a higher 1600p native resolution. Black-white and gray-gray response times are still relatively slow which shouldn't negatively impact most office-type workloads.
Dell offers lower-end dimmer 1200p panel options that are half as bright as our 1600p configuration. Annoyingly, Dell does not advertise the color coverage of these panels and so we suspect these cheaper options to have inferior colors that are well below the sRGB standard.

The display does not come pre-calibrated. Average grayscale and color deltaE values would sit at 5.6 and 3.3, respectively, which we can knock down to just 2.2 and 1.02 after a calibration with our X-Rite colorimeter. Users can apply our calibrated ICM profile above to get more out of the full sRGB display.

Outdoor visibility is decent under shade and better than on the ThinkPad E14 G4 or ProBook 440 G9 which come with noticeably dimmer displays. If outdoor visibility is important, however, then we recommend taking a look at the HP EliteBook 865 and its ultra-bright 1000-nit display options instead.
Performance — Intel 13th Gen With vPro
Testing Conditions
We set our unit to Ultra Performance mode via Dell Optimizer prior to running the benchmarks below. The software has a very convenient feature that syncs the Dell power profiles with the regular Windows power profiles and so you only need to change the settings once instead of twice. Most other laptops do not carry this feature.
It's recommended that owners become familiar with Optimizer as it is the hub for toggling Dell-specific features like Presence Detection, charging behavior, and more.
Processor
CPU performance is excellent and even 5 to 10 percent faster than the non-vPro Core i5-1335U in the Samsung Galaxy Book3 15. Jumping from the Core i5-1145G7 in the two-year old Latitude 7420 to our Core i5-1345U would boost multi-thread performance by over 2x. The Dell model does not offer Core-P or AMD Ryzen Zen options which have boosted multi-thread performance even more.
Performance would drop by about 17 percent over time when running CineBench R15 xT in a loop due to the limited Turbo Boost potential of the system. We recorded a much steeper drop of 40 percent during the middle of the test, but this quickly recovered as shown by our graph below.
Upgrading to the pricier Core i7-1365U is expected to boost performance performance by just 5 to 10 percent over our Core i5 configuration based on our experience with the Lenovo ThinkPad X1 Carbon G11.

Storage Devices — Single M.2 2242 SSD Only
Our test unit ships with the midrange Samsung PM9B1 MZ9L4512HBLU PCIe4 x4 NVMe SSD offering maximum read and write rates of 3500 MB/s and 2500 MB/s, respectively. The drive is able to sustain these rates for extended periods of stress as shown by our DiskSpd loop results below. A thermal pad and head spreader come standard atop the SSD to aid in heat dissipation.
There is no secondary SSD slot for expansion.

GPU Performance — Iris Xe Chugs Along
Our Iris Xe 80 EUs performs 15 to 20 percent faster than the average laptop in our database equipped with the same integrated GPU. The advantage can be attributed to the newer and faster 13th gen Core i5-1345U whereas the vast majority of Iris Xe laptops in our database are running on 11th gen and 12th gen processors. Upgrading to the Core i7-1355U or i7-1365U configurations with Iris Xe 96 EUs is expected to boost GPU performance by another 10 to 20 percent.
System performance when on Balanced mode is not significantly slower than on Performance mode as shown by the 3DMark 11 results below. CPU performance would fall by just a few percentage points.
