The XPS convertible for business users: Dell Latitude 9440 2-in-1 review
While the Latitude 9420 2-in-1 and Latitude 9430 2-in-1 share the same chassis design, this year's Latitude 9440 2-in-1 is a complete refresh from top to bottom. Unveiled during CES 2023, the Latitude 9440 2-in-1 incorporates design features of the XPS 13 Plus for a more attractive look. Internals have been upgraded from Intel 12th gen Alder Lake-U to 13th gen Raptor Lake-U processor options as well.
Our unit in review is an upper-end configuration with the Core i7-1365U vPro CPU, 32 GB of fast LPDDR5x-6400 soldered RAM, and a 1 TB NVMe SSD for approximately $2900 USD. Lesser SKUs are available starting with the Core i5-1335U for $1900, but all options otherwise ship with the same 2560 x 1600 IPS touchscreen and integrated Iris Xe graphics.
Alternatives to the Latitude 9440 2-in-1 include other high-end business subnotebooks like the Lenovo ThinkPad X1 Yoga G8, Asus ExpertBook B7 Flip, or the HP EliteBook series.

Case — Looking Better And Just As Strong
When in the closed position, the Latitude 9440 2-in-1 looks similar to most other Latitude models. When opened, however, the changes and XPS inspirations become obvious. The Zero-Lattice keyboard has been lifted directly from the XPS 13 Plus while the clickpad now has defined edges which was a major criticism of the "invisible" clickpad on the XPS 13 Plus. Meanwhile, the row of touch-sensitive buttons on the XPS has been reimagined and repositioned along the top half of the clickpad instead. The up-firing speakers along the sides of the keyboard have been carried over from last year's Latitude 9430 2-in-1.
All the physical changes have thankfully not impacted rigidity or build quality. Attempting to twist the base, lid, or keyboard center would result in just minimal warping that is in line with the Latitude 9430 2-in-1 or HP Spectre x360 13.5. It actually feels stronger than the 13-inch XPS 13 Plus perhaps due to its larger 14-inch form factor.
The new 2023 model is thicker and heavier than the outgoing 2022 design despite all the physical changes. Though the increases are slight, they're enough to make the system a bit heavier than competing models like the ThinkPad X1 Yoga G8 or ExpertBook B7 Flip by about 200 grams each.
Connectivity — Hope You Like USB-C
Port options are arguably worse than on last year's Latitude 9430 2-in-1. Whereas the older model integrates USB-A, MicroSD, and even HDMI, the Latitude 9440 2-in-1 trades away all of them in favor of USB-C and nothing else. We understand the forward-thinking nature and versatility of USB-C, but it's still a hard sell especially when competitors like the Asus ExpertBook B7 Flip or Lenovo ThinkPad X1 Yoga G8 still integrate a wider variety of ports to reduce reliance on dongles.
Communication
An Intel AX211 comes standard for Wi-Fi 6E and Bluetooth 5.2 connectivity. We experienced consistent transfer rates and no issues when paired to our Asus AXE11000 6 GHz network.

Webcam
The 2 MP webcam hasn't been upgraded from last year's design. IR and a key-activated shutter come standard for Hello and privacy, respectively.
Maintenance
The bottom panel is easily removable with just a Phillips screwdriver. There isn't much to upgrade, however, beyond the M.2 SSD and M.2 WAN slots. The WAN antenna are unfortunately not included if configured without a WAN card.
Accessories And Warranty
The retail box ships with a small USB-C to USB-A adapter to make up for the limited port selection. A one-year limited manufacturer warranty comes standard instead of the three-year warranty period that certain Precision models may come with.
Input Devices — Looks And Feels Like An XPS 13 Plus
Keyboard
Visually, the Zero-Lattice keyboard helps to distinguish the model from other laptops and it allows for relatively larger keycap sizes as well. On the other hand, the typing experience isn't noticeably better as travel and feedback remain shallow and soft, respectively. The keyboards on an HP EliteBook or LG Gram, for example, are firmer and deeper. At least clatter is relatively quiet due to the softer key feedback.
Touchpad
The clickpad is larger than the one on last year's design (13.5 x 9 cm vs. 11.5 x 7.2 cm) and most other 14-inch laptops for that matter. Traction is incredibly smooth to the point of feeling almost slippery when moving at slower speeds. Unfortunately, feedback when pressing down on the clickpad is very spongy with an unsatisfying click. Simple actions like dragging and dropping are difficult to perform because of the poor feedback. This would have just been a minor complaint for a typical gaming laptop, but we find this drawback to be more serious for a business-centric subnotebook like the Latitude.
A new feature unique to the 9440 2-in-1 is the Haptic Collaboration Touchpad which is essentially a set of four touch-sensitive buttons on the clickpad for toggling the camera, microphone, screen share, and chat window. The main problem, however, is that the commands are exclusive to Zoom calls — business users who rely on Microsoft Teams, Discord, Google Hangouts, or other conferencing software are completely out of luck.
Display — Same As The Latitude 9420 2-in-1
Dell has been deploying the same AU Optronics B140QAN IPS panel for its 14-inch Latitude series for several years now. Thus, the Latitude 9440 2-in-1 uses the same panel as on the older Latitude 9420 2-in-1 and so there are no major upgrades to the viewing experience. This isn't necessarily a bad thing as the AUO B140QAN is an excellent panel for office-type workloads, but it would have been nice to see higher refresh rates or deeper P3 color options to better differentiate the Latitude 9440 2-in-1 from its predecessors.

The panel is well-calibrated out of the box with average grayscale and color deltaE values of just 1.6 and 2.33, respectively. Calibrating it further ourselves would result in even lower DeltaE values of just 1.5 and 0.93. Owners can apply our calibrated ICM profile above, but it's not absolutely necessary in this case.

Outdoor visibility is similar to last year's model since display brightness has not changed. We would love to see 1000-nit panel options in the future much like what HP offers on the EliteBook 840.
Performance — Similar To Last Year's Model
Testing Conditions
We set Dell Optimizer to Ultra Performance mode prior to running the benchmarks below. Conveniently, the Dell power profiles can be synced with the Windows power profiles unlike on most other laptops.
Processor
The Core i7-1365U may be newer than the Core i7-1265U on last year's Latitude, but the two CPUs perform almost identically. Even the Turbo Boost and throttling behavior between them are similar as exemplified by our CineBench R15 xT loop results below. It's a shame that Dell doesn't offer any Core-P options which could have boosted multi-thread performance by up to 40 percent based on our experience with the 2023 Framework Laptop.
Downgrading to the Core i5-1345U vPro or i5-1335U from our Core i7-1365U is expected to reduce multi-thread performance by about 20 percent.

Storage Devices
Our test unit ships with a midrange 1 TB Samsung PM9B1 PCIe4 x4 NVMe SSD offering read and write rates of up to 3700 MB/s and 3000 MB/s, respectively. Performance, however, would slow after just a minute of heavy usage. For example, transfer rates when running DiskSpd for 8 minutes would be as high as 3700 MB/s during the start of the test before steadily declining to 2600 MB/s over time as shown by the graph below. Performance is still sufficient for a Core U-powered laptop nonetheless.
Keep in mind that the laptop supports the shorter M.2 2242 form factor and not the longer and more common 2280 likely to keep weight at a minimum.
