Dell Latitude 7410 Business Laptop with an Intel Core i7-10610U vPro processor outperformed Lenovo ThinkPad T14s Laptop with an AMD Ryzen 7 PRO 4750U processor November 2020 (Revised) | 2 A different perspective on performance while working unplugged To get another view on unplugged performance, we prepared the systems identically using the SYSmark configuration tool (see page 10 in the appendices for more information). Then, using the same system and benchmark settings for both business laptops, we ran them through the SYSmark 2018 benchmark testing twice--first to measure system performance when they were plugged in and the second time to measure system performance when they were unplugged. For the plugged-in results, we allowed SYSmark to run the devices through its workloads three times and took the median score of those three runs. For the unplugged results, we fully charged each system and ran the benchmark once. We repeated this process a total of three times on each system and reported the median score. In the plugged-in test, the Dell Latitude 7410 Business Laptop, powered by an Intel Core i7-10610U vPro processor and a 68-Whr battery, delivered 9 percent faster system responsiveness. 9% faster system responsiveness Based on SYSmark 2018 overall rating while plugged in Score 1,489 1,364 Dell Latitude 7410 Business Laptop powered by an Intel Core i7-10610U vPro processor (68-Whr battery) Lenovo ThinkPad T14s Laptop powered by an AMD Ryzen 7 PRO 4750U processor (57-Whr battery) Figure 3: SYSmark 2018 overall performance rating while plugged in.

Dell Latitude 7410 Business Laptop with an Intel Core i7-10610U vPro processor outperformed Lenovo ThinkPad T14s Laptop with an AMD Ryzen 7 PRO 4750U processor November 2020 (Revised) | 3 Appendices We concluded our hands-on testing on October 30, 2020. During testing, we determined the appropriate hardware and software configurations and applied updates as they became available. The results in this report reflect configurations that we finalized on August 5, 2020 or earlier. Unavoidably, these configurations may not represent the latest versions available when this report appears. Our results Table 1: Results of our benchmark testing. These scores are the median of three runs.

Dell Latitude 7410 Business Laptop with an Intel Core i7-10610U vPro processor outperformed Lenovo ThinkPad T14s Laptop with an AMD Ryzen 7 PRO 4750U processor November 2020 (Revised) | 6 Measuring performance-qualified battery life MobileMark 2018 Avoiding antivirus software conflicts MobileMark 2018 is not compatible with any virus-scanning software, so we uninstalled any such software present on the laptops before we installed the benchmark. Avoiding pre-installed software conflicts MobileMark 2018 installs the following applications, which its test scripts employ: Productivity ·Adobe® Acrobat® Pro DC ·AutoIT 3.3.14.2 ·Google® ChromeTM ·Microsoft Excel 2016 ·Microsoft OneNote 2016 ·Microsoft Outlook 2016 ·Microsoft PowerPoint 2016 ·Microsoft Word 2016 ·Windows Zip Creativity ·Adobe Photoshop® CC ·Adobe Lightroom® Classic CC ·CyberLink PowerDirector® 2015 Web Browsing ·Google Chrome ·Microsoft Movies & TV If any of these applications already exist on the system under test, they could cause problems with the benchmark due to software conflicts. To avoid any such issues, we uninstalled all conflicting pre-installed software applications--including different versions of any of the programs MobileMark 2018 uses--before we installed the benchmark. Adjusting display brightness and power settings The brightness of a laptop's display affects its battery life. Therefore, BAPCo requires that, before you test with MobileMark 2018, you ensure the brightness of the laptop's monitor is greater than or equal to 200 nits in the center of a completely white screen while the laptop is unplugged and running on battery power. The measurement follows the standards from the Video Electronics Standards Association (www.vesa.org). We complied with this standard for all our tests by setting each laptop's brightness as close to 200 nits as we could without going below that level. We used the following procedure before we started each test. Note: This procedure assumes we began with the plugged into the power supply. 1. To create a completely blank, white screen, open Microsoft Paint by clicking StartAll ProgramsAccessoriesPaint. 2. To open the Resize and Skew dialog , press Ctrl+W. 3. Under Horizontal and Vertical, enter 200, and click OK. 4. Click the View tab. 5. To view a white screen, click Full screen. 6. To allow the screen to warm, wait 45 minutes. 7. Unplug the laptop from the power supply, and measure the display's brightness using a luminance meter in the center of the screen. (We used a Gossen Mavolux5032C luxmeter.) 8. If the reading is below or significantly greater than 200 nits, adjust the screen brightness to as close to 200 nits as you can without going under, and retest: a. Click Start. b. In the Windows Start search box, type display settings c. Adjust the slider to change the Display brightness to the correct percentage that produces no less than 200 nits. 9. Allow the laptop to run on battery power for 10 minutes, re-measure the display, and adjust the brightness up or down as necessary. 10. Verify that the laptop saved the brightness setting by plugging in the system, unplugging it, and taking another reading.
