The XPRTs can help with your holiday shopping

on November 19, 2020

The biggest shopping days of the year are fast approaching, and if you’re researching phones, tablets, Chromebooks, or laptops in preparation for Black Friday and Cyber Monday sales, the XPRTs can help! One of the core functions of the XPRTs is to help cut through all the marketing noise by providing objective, reliable measures of a device’s performance. For example, instead of trying to guess whether a new Chromebook is fast enough to handle the demands of remote learning, you can use its CrXPRT and WebXPRT performance scores to see how it stacks up against the competition when handling everyday tasks.

A good place to start your search for scores is our XPRT results browser. The browser is the most efficient way to access the XPRT results database, which currently holds more than 2,600 test results from over 100 sources, including major tech review publications around the world, OEMs, and independent testers. It offers a wealth of current and historical performance data across all the XPRT benchmarks and hundreds of devices. You can read more about how to use the results browser here.

Also, if you’re considering a popular device, chances are good that someone has already published an XPRT score for that device in a recent tech review. The quickest way to find these reviews is by searching for “XPRT” within your favorite tech review site, or by entering the device name and XPRT name (e.g. “Apple iPad” and “WebXPRT”) in a search engine. Here are a few recent tech reviews that use one or more of the XPRTs to evaluate a popular device:

Notebookcheck used WebXPRT in reviews of the Apple iPhone 12, Google Pixel 5, and Dell Latitude 7410 Chromebook Enterprise 2-in-1.
PCMag used WebXPRT to evaluate the new Apple MacBook Pro 13”, MacBook Air, and HP Chromebook x360 14c.
LaptopMag used WebXPRT in a Best student Chromebooks for back to school 2020 review. This article can still be helpful if you’ve discovered that your child’s existing Chromebook isn’t handling the demands of remote learning well.
PCWorld used WebXPRT to test the new Lenovo Flex 5G laptop.

The XPRTs can help consumers make better-informed and more confident tech purchases this holiday season, and we hope you’ll find the data you need on our site or in an XPRT-related tech review. If you have any questions about the XPRTs, XPRT scores, or the results database please feel free to ask!

Following up on CrXPRT 2 battery life errors

By Justin Greene

on May 21, 2020

A few weeks ago, we discussed error messages that a tester received when starting up CrXPRT 2 after a battery life test. CrXPRT 2 battery life tests require a full battery rundown, after which the tester plugs in the Chromebook, turns it on, opens the CrXPRT 2 app, and sees the test results. In the reported cases, the tester opened the app after a battery life test that seemed successful, but saw “N/A” or “test error” messages instead of the results they expected.

During discussions about the end-of-test system environment, we realized that some testers might be unclear about how to tell that the battery has fully run down. During the system idle portion of CrXPRT 2 battery life test iterations, the Chromebook screen turns black and a small cursor appears somewhere on the screen to let testers know the test is still in progress. We believe that some testers, seeing the black screen but not the cursor, believe the system has shut down. Restarting CrXPRT 2 before the battery life test is complete could explain some of the “N/A” or “test error” messages users have reported.

If you see a black screen without a cursor, you can check to see whether the test is complete by looking for the small system power indicator light on the side or top of most Chromebooks. These are usually red, orange, or green, but if a light of any color is lit, the test is still underway. When the light goes out, the test has ended. You can plug the system in and power it on to see results.

Note that some Chromebooks provide low-battery warnings onscreen. During CrXPRT 2 battery life runs, testers should ignore these.

We hope this clears up any confusion about how to know when a CrXPRT 2 battery life test has ended. If you’ve received repeated “N/A” or “test error” messages during your CrXPRT 2 testing and the information above does not help, please let us know!

Results details and unexpected behavior with the CrXPRT 2 battery life test

By Justin Greene

on April 30, 2020

It’s been two weeks since the CrXPRT 2 public release, and we’re happy to see widespread interest in the test right out of the gate!

This week, we received a couple of questions about its battery life test from Melissa Riofrio at PCWorld. First, she asked for clarification about the relationship between the rundown time and the 30-minute increments that appear in the iteration details table for each battery life run. Second, she asked what could be causing her to get “N/A” and “test error” battery life results at the end of what appeared to be successful tests. Both topics may be of interest to other CrXPRT 2 testers, so we’ve decided to address them here in the blog and invite our readers to provide any relevant feedback.

Rundown time vs. elapsed time

When you’re viewing previous CrXPRT 2 test results and click the Details link for a specific battery life test run, a window displaying additional test information appears (the screenshot below shows an example). The window first provides performance details, then presents a table with several data points for each iteration.

The data point in the far-right column, elapsed time, can be slightly confusing. Each test iteration runs for 30 minutes, and this column provides a cumulative total of these 30-minute increments. In some instances, these totals accurately reflect the actual time elapsed from the time that testing begins. However, if the test system shuts down for some reason before running the entire iteration, this table will still show the entire 30 minutes allotted for the that iteration. In these cases, the cumulative elapsed time value in the far-right column will not match the rundown time that the test reports for the system’s battery life. For that reason, testers should always consider rundown time as the definitive value for battery life.

“N/A” and “test error” battery life results after apparently successful tests

We’re actively investigating this issue at present. We’ve tested a wide range of Chromebooks, both old and new, on several versions of Chrome OS, including the latest versions, and have been unable to reproduce the problem. Have you witnessed this behavior at the end of a CrXPRT 2 battery life test? If so, we’d love to get more information from you about the system under test and your testing procedures, so please contact us.

We’re grateful to Melissa for raising these questions, and we appreciate everyone’s feedback on CrXPRT 2. Hopefully, we’ll soon be able to determine the cause of the “N/A” and “test error” results and find a solution. We’ll be sure to share that information here in the blog once we do.

Adapting to a changing tech landscape

By Justin Greene

on April 23, 2020

The BenchmarkXPRT Development Community started almost 10 years ago with the development of the High Definition Experience & Performance Ratings Test, also known as HDXPRT. Back then, we distributed the benchmark to interested parties by mailing out physical DVDs. We’ve come a long way since then, as testers now freely and easily access six XPRT benchmarks from our site and major app stores.

Developers, hardware manufacturers, and tech journalists—the core group of XPRT testers—work within a constantly changing tech landscape. Because of our commitment to providing those testers with what they need, the XPRTs grew as we developed additional benchmarks to expand the reach of our tools from PCs to servers and all types of notebooks, Chromebooks, and mobile devices.

As today’s tech landscape continues to evolve at a rapid pace, our desire to play an active role in emerging markets continues to drive us to expand our testing capabilities into areas like machine learning (AIXPRT) and cloud-first applications (CloudXPRT). While these new technologies carry the potential to increase efficiency, improve quality, and boost the bottom line for companies around the world, it’s often difficult to decide where and how to invest in new hardware or services. The ever-present need for relevant and reliable data is the reason many organizations use the XPRTs to help make confident choices about their company’s future tech.

We just released a new video that helps to explain what the XPRTs provide and how they can play an important role in a company’s tech purchasing decisions. We hope you’ll check it out!

We’re excited about the continued growth of the XPRTs, and we’re eager to meet the challenges of adapting to the changing tech landscape. If you have any questions about the XPRTs or suggestions for future benchmarks, please let us know!

Principled Technologies and the BenchmarkXPRT Development Community release the CrXPRT 2 benchmark for Chromebooks

By Justin Greene

on April 20, 2020

Durham, NC, April 20— Principled Technologies and the BenchmarkXPRT Development Community have released CrXPRT 2, a free app that measures Chromebook battery life, as well as how fast a Chromebook handles everyday tasks like playing video games, watching movies, editing pictures, and doing homework. Testers can install the app on Chromebooks from the Chrome Web Store or by clicking the Chrome Web Store button on CrXPRT.com.

The CrXPRT 2 performance test, which measures a Chromebook’s speed, gives testers an overall score and individual scores for each workload. In addition to an estimated battery life expressed in hours and minutes, the battery life test produces a separate performance score and a frames per second (FPS) rate for a built-in HTML5 gaming component. CrXPRT is user-friendly, delivering results that consumers can understand.

“CrXPRT is a popular, easy-to-use benchmark run by manufacturers, tech journalists, and consumers all around the world,” said Bill Catchings, co-founder of Principled Technologies, which administers the BenchmarkXPRT Development Community. “CrXPRT 2 continues CrXPRT’s legacy of providing relevant and reliable performance and battery life data for Chrome OS devices.”

CrXPRT is part of the BenchmarkXPRT suite of performance evaluation tools, which includes AIXPRT, CloudXPRT, WebXPRT, TouchXPRT, HDXPRT, and MobileXPRT. The XPRTs help users get the facts before they buy, use, or evaluate tech products such as servers, desktops, laptops, and tablets.

CrXPRT 2 is here!

By Justin Greene

on April 16, 2020

We’re excited to announce that CrXPRT 2 is now available to the public! Testers can install the app on Chromebooks by using this link to the Chrome Web Store listing, or by clicking the Chrome Web Store button on CrXPRT.com.

For those who may have missed our previous discussions about what’s new with CrXPRT 2, here is a recap of the key differences between CrXPRT 2015 and CrXPRT 2:

CrXPRT 2 has an all-new UI, with a focus on intuitive navigation.
The CrXPRT 2 performance test includes six of the seven workloads in CrXPRT 2015. Newer versions of Chrome can’t run the Photo Collage workload without a workaround, so we removed it from CrXPRT 2.
We updated the image resolutions and sizes for the Photo Effects and Face Detection workloads.
The battery life test now requires a full rundown, so the length of battery life tests will vary according to the battery life of the systems under test.
CrXPRT 2 no longer requires testers to enter luminance and audio measurements for battery life tests.
We added a second video playback segment to each battery life iteration.

As we’ve noted before, CrXPRT 2 overall performance test scores and battery life measurements are not comparable to CrXPRT 2015 scores. For testers that need to access CrXPRT 2015 for legacy comparison testing, we will continue to make CrXPRT 2015 available via a link on CrXPRT.com.

We appreciate everyone’s input during the CrXPRT 2 development process. If you have any further questions about CrXPRT 2, please let us know!
