A PRINCIPLED TECHNOLOGIES TEST REPORT
Commissioned by Intel Corp.
COMPARING CHROMEBOOKS IN THE CLASSROOM
Chromebooks with faster processors can reduce the time it takes to do most
tasks, which means one thing: your students can get more work done each class period.
While slower devices can lead to distracted or frustrated students, better performing
devices can help keep students engaged. With faster Chromebooks, students can save
time on tasks they do over and over, which quickly adds up to a lot more time for
learning.
In the Principled Technologies labs, we put two Chromebooks to the test in
history project and anatomy class scenarios with commonly used apps including
BioDigital Human, Edmodo®, Google Docs™, and WeVideo®.
The results were clear: the Dell Chromebook 11 with the Intel Core i3 processor
provided a significantly better experience for students than the NVIDIA Tegra K1
processor-based Acer Chromebook 13. In our two scenarios, students saved valuable
classroom time with the Dell Chromebook 11—over 52 seconds while creating a history
project and over 52 seconds while learning anatomy in science class. We also found that
the Dell Chromebook 11 delivered a smoother and more responsive experience in
BioDigital Human and Google Maps—83 percent and 60 percent more frames per
second, respectively.
Minutes matter—the time saved with the Intel processor-powered Dell
Chromebook 11 can quickly add up for students during a class period. The bottom line:
in our tests, the Dell Chromebook 11 with the Intel Core i3 processor provided a better
learning experience when handling common classroom tasks.

WHAT’S IN A CHROMEBOOK?
What’s inside your Chromebook can make all the difference in how your device
performs. The processor that drives these devices is key to getting the performance you
want. To help you make the right device choice for your school, we compared the Intel
Core i3 processor-based Dell Chromebook 11 against the NVIDIA Tegra K1 processor-
based Acer Chromebook 13. For details about the systems we tested, see Appendix A. If
you want to learn more about our test process, take a look at Appendix B.
Less waiting while creating a history project with the Dell Chromebook 11
Jayden and his classmates are working on an US history video project. He opens
a new WeVideo project and starts gathering facts about the Declaration of
Independence in Google Docs. He makes title cards in WeVideo and starts writing a
script to narrate the video. A quick Wikipedia® search tells Jayden that Independence
Hall in Philadelphia is the birthplace of the American government, so he opens Google
Maps™ and uses Street View™ to tour the site. He uses the PicMonkey™ extension to
take screenshots of the building to include in his video. Before saving the photos to his
Google Drive, Jayden edits the images with the PicMonkey app. He picks his two favorite
images in the Gallery app and uploads them to WeVideo, where he adds transitions to
the images in the video timeline. Jayden publishes a rough draft to his Google Drive™
and previews his video presentation.
Figure 1: The Dell Chromebook 11 with the Intel Core i3 processor outperformed the NVIDIA Tegra K1 processor-based
Acer Chromebook 13 in our history project scenario.
A Principled Technologies test report 3Comparing Chromebooks in the classroom
As Figure 1 shows, Jayden and his classmates would spend less than half the
amount of time waiting while creating his history project with the Intel Core i3
processor-powered Dell Chromebook 11. In our scenario, Jayden would save over 52
seconds with the Dell Chromebook 11—valuable time that would add up over the
course of a classroom period. Jayden would save time during each step with the Dell
Chromebook 11, including almost 9 seconds each time he captures a screenshot with
the PicMonkey Extension. With the NVIDIA Tegra K1 processor-based Acer Chromebook
13, he would have to wait well over 6 seconds longer each time he created a new
document in Google Docs. When you have to do tasks like this over and over, those
seconds add up to lots of wasted class time.
Figure 2: The Dell Chromebook 11 with the Intel Core i3 processor delivered more frames per second than the NVIDIA Tegra K1
processor-based Acer Chromebook 13 when zooming in Google Maps.
As Figure 2 shows, the Intel Core i3 processor-powered Dell Chromebook 11
also rendered 60 percent more frames per second when zooming in Google Maps to
give Jayden a smoother and more responsive experience than with the NVIDIA Tegra K1
processor-based Acer Chromebook 13. Even better for Jayden: the Dell Chromebook 11
was able to support the full version of Google maps (see Figure 3), which means he
could access 3D maps for the Earth, Mars, and the Moon, if he wanted. With the NVIDIA
Tegra K1 processor-based Chromebook, Jayden would be limited to Lite mode, where he
would be stuck accessing only basic maps and satellite footage (see Figure 4).
Jayden would
save 9 seconds
each time he
saved a
screenshot with
the Dell
Chromebook 11.

Less waiting while learning in science class with the Dell Chromebook 11
Sophia’s science class begins with an icebreaker: she and a partner have four
minutes to name as many bones in the human body as possible. Sophia opens Google
Docs and shares a new document with her partner, and they work together to complete
the assignment. Sophia’s teacher starts a lesson on human anatomy, and Sophia follows
along in a Google Slides presentation. After the lesson, Sophia’s class looks at BioDigital
Human, and Sophia opens the app to view the Allergic Rhinitis condition with her class.
While working in BioDigital Human, Sophia and her classmates use Glogster™ to create a
Glog® about the conditions. At the end of class, Sophia and her classmates are given
time to work on an anatomy lesson in Khan Academy®. Sophia opens Edmodo and
checks her planner to open the link to the Khan Academy assignment.
Figure 5: The Dell Chromebook 11 with the Intel Core i3 processor outperformed the NVIDIA Tegra K1 processor-based Acer
Chromebook 13 in our science class scenario.
A Principled Technologies test report 6Comparing Chromebooks in the classroom
As Figure 5 shows, Sophia and her classmates would save valuable time with the
Intel Core i3 processor-powered Dell Chromebook 11 while learning anatomy in science
class—over 52 seconds in our scenario. For Sophia’s teacher, that time saved would
quickly add up and ultimately mean more time for teaching the lesson. Sophia would
save well over 10 seconds each time she opens the Google Slides presentation with the
Dell Chromebook 11. She would have to wait 9 seconds longer each time she opens
BioDigital Human with the NVIDIA Tegra K1 processor-based Chromebook, and would
also lose time switching the skeleton model or loading a condition.
Figure 6: The Dell Chromebook 11 with the Intel Core i3 processor delivered more frames per second than the NVIDIA Tegra K1
processor-based Acer Chromebook 13 when rotating the skeleton model in BioDigital Human.
As Figure 6 shows, the Intel Core i3 processor-powered Dell Chromebook 11
also rendered 83 percent more frames per second when rotating the skeleton model in
the BioDigital Human app to give Sophia a smoother and more responsive experience
than with the NVIDIA Tegra K1 processor-based Acer Chromebook 13.
CONCLUSION
Students are in class for a limited time, so you need to make each minute count.
By choosing Chromebooks that can speed up common tasks for your students, you can
make the most of class time.
Our hands-on tests showed that the Intel Core i3 processor-powered Dell
Chromebook 11 would save valuable time in the classroom by reducing the amount of
time students would have to wait while learning. In our two scenarios, Jayden would
spend 51 percent less time waiting while creating a history project, and Sophia would
spend 48 percent less time waiting while learning anatomy in science class. That time
saved with the Dell Chromebook 11 equals more time for learning. We also found the
Intel Core i3 processor-powered Dell Chromebook 11 provided a better visual
experience in BioDigital Human and Google Maps, delivering up to 83 percent more
frames per second.
Sophia would save
well over 10 seconds
each time she opens
the Google Slides
presentation with the
Dell Chromebook 11.

Comparing Chromebooks in the classroom - Corei3

  • 1. FEBRUARY 2015 A PRINCIPLED TECHNOLOGIES TEST REPORT Commissioned by Intel Corp. COMPARING CHROMEBOOKS IN THE CLASSROOM Chromebooks with faster processors can reduce the time it takes to do most tasks, which means one thing: your students can get more work done each class period. While slower devices can lead to distracted or frustrated students, better performing devices can help keep students engaged. With faster Chromebooks, students can save time on tasks they do over and over, which quickly adds up to a lot more time for learning. In the Principled Technologies labs, we put two Chromebooks to the test in history project and anatomy class scenarios with commonly used apps including BioDigital Human, Edmodo®, Google Docs™, and WeVideo®. The results were clear: the Dell Chromebook 11 with the Intel Core i3 processor provided a significantly better experience for students than the NVIDIA Tegra K1 processor-based Acer Chromebook 13. In our two scenarios, students saved valuable classroom time with the Dell Chromebook 11—over 52 seconds while creating a history project and over 52 seconds while learning anatomy in science class. We also found that the Dell Chromebook 11 delivered a smoother and more responsive experience in BioDigital Human and Google Maps—83 percent and 60 percent more frames per second, respectively. Minutes matter—the time saved with the Intel processor-powered Dell Chromebook 11 can quickly add up for students during a class period. The bottom line: in our tests, the Dell Chromebook 11 with the Intel Core i3 processor provided a better learning experience when handling common classroom tasks.
  • 2. A Principled Technologies test report 2Comparing Chromebooks in the classroom WHAT’S IN A CHROMEBOOK? What’s inside your Chromebook can make all the difference in how your device performs. The processor that drives these devices is key to getting the performance you want. To help you make the right device choice for your school, we compared the Intel Core i3 processor-based Dell Chromebook 11 against the NVIDIA Tegra K1 processor- based Acer Chromebook 13. For details about the systems we tested, see Appendix A. If you want to learn more about our test process, take a look at Appendix B. Less waiting while creating a history project with the Dell Chromebook 11 Jayden and his classmates are working on an US history video project. He opens a new WeVideo project and starts gathering facts about the Declaration of Independence in Google Docs. He makes title cards in WeVideo and starts writing a script to narrate the video. A quick Wikipedia® search tells Jayden that Independence Hall in Philadelphia is the birthplace of the American government, so he opens Google Maps™ and uses Street View™ to tour the site. He uses the PicMonkey™ extension to take screenshots of the building to include in his video. Before saving the photos to his Google Drive, Jayden edits the images with the PicMonkey app. He picks his two favorite images in the Gallery app and uploads them to WeVideo, where he adds transitions to the images in the video timeline. Jayden publishes a rough draft to his Google Drive™ and previews his video presentation. Figure 1: The Dell Chromebook 11 with the Intel Core i3 processor outperformed the NVIDIA Tegra K1 processor-based Acer Chromebook 13 in our history project scenario.
  • 3. A Principled Technologies test report 3Comparing Chromebooks in the classroom As Figure 1 shows, Jayden and his classmates would spend less than half the amount of time waiting while creating his history project with the Intel Core i3 processor-powered Dell Chromebook 11. In our scenario, Jayden would save over 52 seconds with the Dell Chromebook 11—valuable time that would add up over the course of a classroom period. Jayden would save time during each step with the Dell Chromebook 11, including almost 9 seconds each time he captures a screenshot with the PicMonkey Extension. With the NVIDIA Tegra K1 processor-based Acer Chromebook 13, he would have to wait well over 6 seconds longer each time he created a new document in Google Docs. When you have to do tasks like this over and over, those seconds add up to lots of wasted class time. Figure 2: The Dell Chromebook 11 with the Intel Core i3 processor delivered more frames per second than the NVIDIA Tegra K1 processor-based Acer Chromebook 13 when zooming in Google Maps. As Figure 2 shows, the Intel Core i3 processor-powered Dell Chromebook 11 also rendered 60 percent more frames per second when zooming in Google Maps to give Jayden a smoother and more responsive experience than with the NVIDIA Tegra K1 processor-based Acer Chromebook 13. Even better for Jayden: the Dell Chromebook 11 was able to support the full version of Google maps (see Figure 3), which means he could access 3D maps for the Earth, Mars, and the Moon, if he wanted. With the NVIDIA Tegra K1 processor-based Chromebook, Jayden would be limited to Lite mode, where he would be stuck accessing only basic maps and satellite footage (see Figure 4). Jayden would save 9 seconds each time he saved a screenshot with the Dell Chromebook 11.

  • 5. A Principled Technologies test report 5Comparing Chromebooks in the classroom Less waiting while learning in science class with the Dell Chromebook 11 Sophia’s science class begins with an icebreaker: she and a partner have four minutes to name as many bones in the human body as possible. Sophia opens Google Docs and shares a new document with her partner, and they work together to complete the assignment. Sophia’s teacher starts a lesson on human anatomy, and Sophia follows along in a Google Slides presentation. After the lesson, Sophia’s class looks at BioDigital Human, and Sophia opens the app to view the Allergic Rhinitis condition with her class. While working in BioDigital Human, Sophia and her classmates use Glogster™ to create a Glog® about the conditions. At the end of class, Sophia and her classmates are given time to work on an anatomy lesson in Khan Academy®. Sophia opens Edmodo and checks her planner to open the link to the Khan Academy assignment. Figure 5: The Dell Chromebook 11 with the Intel Core i3 processor outperformed the NVIDIA Tegra K1 processor-based Acer Chromebook 13 in our science class scenario.
  • 6. A Principled Technologies test report 6Comparing Chromebooks in the classroom As Figure 5 shows, Sophia and her classmates would save valuable time with the Intel Core i3 processor-powered Dell Chromebook 11 while learning anatomy in science class—over 52 seconds in our scenario. For Sophia’s teacher, that time saved would quickly add up and ultimately mean more time for teaching the lesson. Sophia would save well over 10 seconds each time she opens the Google Slides presentation with the Dell Chromebook 11. She would have to wait 9 seconds longer each time she opens BioDigital Human with the NVIDIA Tegra K1 processor-based Chromebook, and would also lose time switching the skeleton model or loading a condition. Figure 6: The Dell Chromebook 11 with the Intel Core i3 processor delivered more frames per second than the NVIDIA Tegra K1 processor-based Acer Chromebook 13 when rotating the skeleton model in BioDigital Human. As Figure 6 shows, the Intel Core i3 processor-powered Dell Chromebook 11 also rendered 83 percent more frames per second when rotating the skeleton model in the BioDigital Human app to give Sophia a smoother and more responsive experience than with the NVIDIA Tegra K1 processor-based Acer Chromebook 13. CONCLUSION Students are in class for a limited time, so you need to make each minute count. By choosing Chromebooks that can speed up common tasks for your students, you can make the most of class time. Our hands-on tests showed that the Intel Core i3 processor-powered Dell Chromebook 11 would save valuable time in the classroom by reducing the amount of time students would have to wait while learning. In our two scenarios, Jayden would spend 51 percent less time waiting while creating a history project, and Sophia would spend 48 percent less time waiting while learning anatomy in science class. That time saved with the Dell Chromebook 11 equals more time for learning. We also found the Intel Core i3 processor-powered Dell Chromebook 11 provided a better visual experience in BioDigital Human and Google Maps, delivering up to 83 percent more frames per second. Sophia would save well over 10 seconds each time she opens the Google Slides presentation with the Dell Chromebook 11.

As journalists, they published over a thousand articles on a wide array of technology subjects. They created and led the Ziff-Davis Benchmark Operation, which developed such industry-standard benchmarks as Ziff Davis Media’s Winstone and WebBench. They founded and led eTesting Labs, and after the acquisition of that company by Lionbridge Technologies were the head and CTO of VeriTest.
