A Principled Technologies report: Hands-on testing. Real-world results.
Work happy on the go with greater unplugged performance and longer battery life using an HP EliteBook 645 G10 Notebook PC
vs. a Dell Latitude 5440 laptop
Notebook users shouldn’t have to compromise device performance to squeeze out a few more hours of battery life. Many users expect consistent performance from a device, whether they plug devices in at an office or coworking space or they need to unplug during their commute or at their airport terminal. And when they’re completing mission-critical work on the go, mobile trailblazers need a solution that can deliver both the battery life to complete their workday and performance that won’t slow them down. But with so many compelling choices on the market with high-performance processors, it can be difficult to know which device can best empower a mobile trailblazer.
At PT, we used industry-standard benchmarks to provide real-world battery life estimates and highlight crucial differences between plugged-in and unplugged system performance on an HP EliteBook 645 G10 Notebook PC powered by an AMD Ryzen™ 7 7730U processor and a Dell™ Latitude™ 5440 laptop powered by an Intel® Core™ i7-1355U processor. For personal comfort, we also hand-measured how hot and loud each became while running a CPU-intensive workload. We found that the HP EliteBook 645 G10 Notebook PC powered by an AMD Ryzen™ 7 7730U processor generally delivered better mission-critical performance unplugged and longer battery life than the Dell Latitude 5440 laptop powered by an Intel Core i7-1355U processor.
What we tested
Before we started testing, we set the 14-inch Windows 11 Pro business laptops to “best performance” power mode. For the MobileMark® 2018 battery life tests, we set screen brightness to 205 nits and conducted “best performance” and “best power efficiency” power mode comparisons. We then reset screen brightness to 255 nits for the MobileMark 25 battery life comparisons. Other than making and verifying those changes, we used out-of-box OEM performance settings for both laptops. We tested the following systems:
We ran the following performance-based benchmark tests twice—once with the laptops plugged in and again unplugged while in “best performance” power mode:
PassMark PerformanceTest 11
To test battery life and efficiency, we ran MobileMark 2018 and MobileMark 25 benchmarks twice—once in “best performance” power mode and again in “best power efficiency” power mode. For our surface temperature comparisons, we ran a sustained Cinebench R23 workload for 50 minutes, taking keyboard and bottom hot-spot temperature readings every 10 minutes. We then ran the CPU-intensive workload again for 20 minutes to determine how much noise each laptop’s fan produced under load.
The benchmark scores and battery life results we report reflect the specific configurations we tested. Any difference in the configurations, as well as screen brightness, network traffic, or software additions, can affect these results.

In fact, researchers in a Harvard Business Review case study found that mid-or back-office users across three Fortune 500 companies toggled between apps and websites an average of nearly 1,200 times each day.4 This is one reason our real-world performance, battery life, heat, and noise comparisons under load are so important. With them, teams can focus on completing mission-critical work from anywhere without worry.
Key mobile productivity takeaways
In our PassMark productivity benchmark tests, the unplugged EliteBook 645 G10 we tested experienced a 10.4 percent system performance loss when we switched from plugged-in to unplugged, while performance on the unplugged Latitude 5440 laptop, which scored 10.9 percent higher in the plugged-in comparison, dropped from 4,801.8 to 3,401.6 after we unplugged it. That’s a 29.1 percent mobile productivity drop!
In our Cinebench R23 multi-core benchmark tests, the unplugged EliteBook 645 G10 we tested experienced minimal system performance loss when we switched from plugged-in to unplugged, while performance on the unplugged Latitude 5440 laptop, which scored 8.1 percent higher in the plugged-in comparison, dropped from 10,533 to 6,393 after we unplugged it. That’s a 39.3 percent mobile productivity decrease!
Boost mobile productivity
PassMark PerformanceTest is a productivity benchmark that gathers CPU, disk, memory, and 2D/3D graphics performance metrics before combining the individual component metrics to create a single, overall score, called the PassMark rating. The bigger the overall rating number, the faster the device.5
Better handle demanding workloads
The Cinebench R23 benchmark measures system performance by completing common Cinema 4D tasks that tax multiple CPU cores and modern processor features.6
Battery life and efficiency results: Work where you want, no strings (or cables) attached
While a battery life estimate can be helpful in determining potential performance, running just one test is like trying to paint a portrait with a just a few brushstrokes. An onlooker may begin to discern a general shape and outline, but they could still misjudge what they see. With results from multiple tests, you can paint a fuller picture of battery life performance. To paint our performance picture, we ran battery tests in multiple configurations, including MobileMark 2018, which measures battery life and performance at the same time. It uses real applications, workloads, and data sets to quantify how overall system performance affects the user experience.7 The second test we ran, MobileMark 25, puts devices through scenarios based on the real-world applications and activities business users encounter every day.8 In these tests, we saw a clearer picture of the battery life users might expect from both devices.
Key battery life and efficiency takeaways
In our MobileMark 2018 battery life tests, when we set both devices to “best power efficiency” mode, the HP EliteBook 645 G10 powered by an AMD Ryzen™ 7 7730U processor kept working almost 3 hours longer, received a 21.6 percent higher performance qualification score, and was 33.6 percent more efficient than the Dell Latitude 3440 powered by an Intel Core i7-1355U processor.

Thermal testing results: Stay comfortable without overheating
High-performance processors put off a lot of heat—but laptop manufacturers understand that and dissipate the heat to keep both users and the hardware safe from harm. So, what’s an acceptable temperature when laptops are running CPU-intensive loads like the Cinebench R23 workload we ran for 50 minutes? According to the Make Use Of newsletter, anything under 140°F/60°C is “perfect” in computer-land.9 We took temperature readings every 10 minutes to see how each device compared.
The higher Cinebench R23 performance scores and the well-within-normal-range underside temp (118.0°F) while running this CPU-intensive workload make the HP EliteBook 645 G10 Notebook PC powered by an AMD Ryzen™ 7 7730U processor an attractive choice for mobile trailblazers. By contrast, the underside of the Dell 5440 laptop powered by an Intel Core i7-1355U hit 136.1°F, which could make working with it on your lap for extended periods very uncomfortable.
Key heat and noise takeaways
In our Cinebench R23-driven heat tests, the HP EliteBook 645 G10 powered by an AMD Ryzen™ 7 7730U processor kept its cool and received an 18.6 percent higher Cinebench R23 score than the Dell Latitude 5440 powered by an Intel Core i7-1355U processor.
In our Cinebench R23-driven noise tests, the HP EliteBook 645 G10 powered by an AMD Ryzen™ 7 7730U processor was much quieter than the Dell Latitude 5440 powered by an Intel Core i7-1355U processor.
Acoustic testing results: Keep it quiet
A noisy laptop can be a distraction for anyone—especially mobile trailblazers trying to complete mission-critical tasks as quickly as possible. When we measured the noise levels of each device while idle and while running a Cinebench R23 multi-core workload, we saw that the HP EliteBook 645 G10 Notebook PC was noticeably quieter, with average noise levels under load that were almost six decibels lower than the Dell Latitude 5440 laptop noise levels. It’s important to note that the decibel scale is logarithmic, which means it increases by a power of 10 each time. So, 10dBA is ten times more powerful than 0 dBA and a sound that is 30dBA is 1,000 times more powerful than 0 dBA. For scale, 10dBA is normal breathing while 50dBA is a refrigerator.10
