Intel Core i5-1345U performance debut: Dell Latitude 3440 laptop review

The 2023 Latitude 3440 (not to be confused with the 2013 model of the same name) is a budget 14-inch business laptop from Dell. It's a wallet-friendly alternative to the pricier midrange Latitude 5420, high-end Latitude 7420, or flagship Latitude 9430.
Our configuration in review is a middle SKU with the 13th gen Raptor Lake-U Core i5-1345U vPro CPU, 16 GB RAM, 512 GB NVMe SSD, and 1080p 45% NTSC display for approximately $1100 USD. Other options are available with the lesser Core i3-1315U, higher-end Core i7-1355U, or 1080p display with deeper 72% NTSC colors. Dell plans on offering a discrete GeForce MX550 graphics option in the near future.
Alternatives to the Latitude 3440 include other budget office laptops like the Acer Aspire Vero, HP ProBook 440 G9, Lenovo ThinkPad E14, or the Asus ExpertBook L1.

Case — Just The Basics
The chassis consists of PCR plastic which is to be expected from a budget series. Rigidity is still quite good nonetheless despite the slight creaking of the base when attempting to twist it. Pushing down on the center of the outer lid results in more warping than we would like.

Maintenance
Accessories and Warranty
The retail box includes either a proprietary barrel AC adapter or USB-C AC adapter. We recommend configuring with the former as it frees up the single USB-C port on the laptop for other devices and accessories.
The standard one-year limited warranty applies if purchased in the US.
Input Devices — Comfortable Keyboard With Buggy Clickpad
Keyboard
The typing experience is surprisingly comfortable for a budget laptop. Key feedback feels uniform and firm including the Space and Enter keys.
A two-level white backlight for the keyboard is an optional add-on.
Touchpad
The clickpad (11.5 x 6.8 cm) is slightly larger than the clickpads on the Acer Aspire Vero (10.5 x 6.5 cm) or Asus ExpertBook L1 (10.5 x 6.2 cm). Traction is very smooth even when gliding at slower speeds. However, the clickpad on our unit is unreliable for multi-touch inputs such as two-finger scrolling.
Display — Choose Your IPS Colors Wisely
Our test unit ships with the low-end BOE NE140FH IPS panel offering just 60 percent sRGB colors and a maximum brightness of almost 300 nits. Running on battery power lowers the maximum brightness ceiling to just 265 nits which impacts the viewability of the display outdoors. If deeper and more accurate colors are important for your workloads, then we recommend upgrading to the 72% NTSC option.
Contrast ratio is quite good at about 1500:1 despite the limited color reproduction. Certain SKUs may come with the 768p TN panel which we recommend avoiding.

Color temperature is on the cool side which is typical of budget displays. A proper calibration with our X-Rite colorimeter addresses this shortcoming, but highly saturated colors are still inaccurate due to the limited color space mentioned above.

Performance — 13th Gen Core i5-1345U Offers Very Little Over 12th Gen Series
Testing Conditions
We set our unit to Ultra Performance mode via Dell Optimizer prior to running the performance benchmarks below. The Dell power profiles are conveniently synced with the Windows power profiles unlike on most other laptops.
Processor
The Core i5-1345U is a mixed bag in terms of performance. When running CineBench R15 xT in a loop, performance would drop by as much as 26 percent over time which is more than on competing subnotebooks from Asus or Lenovo as shown by the graph below. The older Core i7-1255U or even Core i5-1235U can still outperform the Core i5-1345U. We're hopeful that other laptop models can run the Core i5-1345U at higher sustainable clock rates than on the Latitude 3440.
Upgrading to the Core i7-1355U is expected to boost CPU performance by as much as 30 to 40 percent based on our time with the Lenovo Yoga 7 16IRL8. However, there is a chance that it may throttle more heavily on the Latitude 3440 much like what we are experiencing on our i5-1345U configuration.
