The holiday shopping season is upon us, and trying to find the right tech gift for your friends or loved ones (or yourself!) can be a daunting task. If you’re considering new phones, tablets, Chromebooks, laptops, or desktops as gifts this year—and are unsure where to get reliable device information—the XPRTs can help!

The XPRTs provide industry-trusted and time-tested measures of a device’s performance that can help you cut through the fog of competing marketing claims. For example, instead of guessing whether the performance of a new gaming laptop justifies its price, you can use its WebXPRT performance score to see how it stacks up against both older models and competitors while tackling everyday tasks.

A great place to start looking for device scores is our XPRT results browser, which lets you access our database of more than 3,700 test results—across all the XPRT benchmarks and hundreds of devices—from over 155 sources, including major tech review publications around the world, OEMs, our own Principled Technologies (PT) testing, and independent submissions. For tips on how to use the XPRT results browser, check out this blog post.

Another way to view information in our results database is by using the WebXPRT 4 results viewer. The viewer provides an information-packed, interactive tool that we created to help people explore data from the set of almost 800 WebXPRT 4 results we’ve curated and published to date on our site. You’ll find detailed instructions in this blog post for how to use the WebXPRT 4 results viewer tool.

If you’re considering a popular device, it’s likely that a recent tech press review includes an XPRT score for it. To find those scores, go to your favorite tech review site and search for “XPRT,” or enter the name of the device and the appropriate XPRT (e.g., “iPhone” and “WebXPRT”) in a search engine. Here are a few recent tech reviews that used the XPRTs to evaluate popular devices:

In addition to XPRT-related resources in the tech press, here at PT we frequently publish reports that evaluate the performance of hot new consumer devices, and many of those reports include WebXPRT scores. For example, check out the results from our extensive testing of a Dell Latitude 7450 AI PC or our in-depth evaluation of three new Lenovo ThinkPad and ThinkBook laptops.

The XPRTs can help you make better-informed and more confident tech purchases this holiday season. 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!

Thinking through a potential WebXPRT 4 battery life test

Justin Greene
By Justin Greene
on October 17, 2024

In recent blog posts, we’ve discussed some of the technical considerations we’re working through on our path toward a future AI-focused WebXPRT 4 auxiliary workload. While we’re especially excited about adding to WebXPRT 4’s AI performance evaluation capabilities, AI is not the only area of potential WebXPRT 4 expansion that we’ve thought about. We’re always open to hearing suggestions for ways we can improve WebXPRT 4, including any workload proposals you may have. Several users have asked about the possibility of a WebXPRT 4 battery life test, so today we’ll discuss what one might look like and some of the challenges we’d have to overcome to make it a reality.

Battery life tests fall into two primary categories: simple rundown tests and performance-weighted tests. Simple rundown tests measure battery life during extreme idle periods and loops of movie playbacks, etc., but do not reflect the wide-ranging mix of activities that characterize a typical day for most users. While they can be useful for performing very specific apples-to-apples comparisons, these tests don’t always give consumers an accurate estimate of the battery life they would experience in daily use.

In contrast, performance-weighted battery life tests, such as the one in CrXPRT 2, attempt to reflect real-world usage. The CrXPRT battery life test simulates common daily usage patterns for Chromebooks by including all the productivity workloads from the performance test, plus video playback, audio playback, and gaming scenarios. It also includes periods of wait/idle time. We believe this mixture of diverse activity and idle time better represents typical real-life behavior patterns. This makes the resulting estimated battery life much more helpful for consumers who are trying to match a device’s capabilities with their real-world needs.

From a technical standpoint, WebXPRT’s cross-platform nature presents us with several challenges that we did not face while developing the CrXPRT battery life test for ChromeOS. While the WebXPRT performance tests run in almost any browser, cross-browser differences and limitations in battery life reporting may restrict any future battery life test to a single browser or browser family. For instance, with the W3C Battery Status API, we can currently query battery status data from non-mobile Chromium-based browsers (e.g., Chrome, Edge, Opera, etc.), but not from Firefox or Safari. If a WebXPRT 4 battery life test supported only a single browser family, such as Chromium-based browsers, would you still be interested in using it? Please let us know.

A browser-based battery life workflow also presents other challenges that we do not face in native client applications, such as CrXPRT:

  • A browser-based battery life test may require the user to check the starting and ending battery capacities, with no way for the app to independently verify data accuracy.
  • The battery life test could require more babysitting in the event of network issues. We can catch network failures and try to handle them by reporting periods of network disconnection, but those interruptions could influence the battery life duration.
  • The factors above could make it difficult to achieve repeatability. One way to address that problem would be to run the test in a standardized lab environment with a steady internet connection, but a long list of standardized environmental requirements would make the battery life test less attractive and less accessible to many testers.

We’re not sharing these thoughts to make a WebXPRT 4 battery life test seem like an impossibility. Rather, we want to offer our perspective on what the test might look like and describe some of the challenges and considerations in play. If you have thoughts about battery life testing, or experience with battery life APIs in one or more of the major browsers, we’d love to hear from you!

For many students, the first day of school is just around the corner, and it’s now time to shop for new tech devices that can help set them up for success in the coming year. The tech marketplace can be confusing, however, with so many brands, options, and competing claims to sort through.

Fortunately, the XPRTs are here to help!

Whether you’re shopping for a new phone, tablet, Chromebook, laptop, or desktop, the XPRTs can provide industry-trusted performance scores that can give you confidence that you’re making a smart purchasing decision.

The WebXPRT 4 results viewer is a good place to start looking for device scores. The viewer displays WebXPRT 4 scores from over 700 devices—including many of the latest releases—and we’re adding new scores all the time. To learn more about the viewer’s capabilities and how you can use it to compare devices, check out this blog post.

Another resource we offer is the XPRT results browser. The browser is the most efficient way to access the XPRT results database, which currently holds more than 3,700 test results from over 150 sources, including major tech review publications around the world, manufacturers, 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, there’s a good chance that a recent tech review includes an XPRT score for that device. There are two quick ways to find these reviews: You can either (1) search for “XPRT” on your preferred tech review site or (2) use a search engine and input the device name and XPRT name, such as “Dell XPS” and “WebXPRT.”

Here are a few recent tech reviews that use one of the XPRTs to evaluate a popular device:

Lastly, here at Principled Technologies, we frequently publish reports that evaluate the performance of hot new consumer devices, and many of those reports include WebXPRT scores. For example, check out our extensive testing of HP ZBook G10 mobile workstations or our detailed comparison of Lenovo ThinkPad, ThinkBook, and ThinkCentre devices to their Apple Mac counterparts.

The XPRTs can help anyone stuck in the back-to-school shopping blues make better-informed and more confident tech purchases. As this new school year begins, 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!

Want to know how your device performs? Explore the XPRT results database

Justin Greene
By Justin Greene
on May 2, 2024

If you only recently started using the XPRT benchmarks, you may not know about one of the free resources we offer—the XPRT results database. Our results database currently holds more than 3,650 test results from over 150 sources, including global tech press outlets, OEM labs, and independent testers. It serves as a treasure trove of current and historical performance data across all the XPRT benchmarks and hundreds of devices. You can use these results and the results of the same XPRTs on your device to get a sense of how well your device performs.

We update the results database several times a week, adding selected results from our own internal lab testing, reliable media sources, and end-of-test user submissions. (After you run one of the XPRTs, you can choose to submit the results, but don’t worry—this is opt-in. Your results do not automatically appear in the database.) Before adding a result, we also look at any available system information and evaluate whether the score makes sense and is consistent with general expectations.

There are three primary ways that you can explore the XPRT results database.

The first is by visiting the main BenchmarkXPRT results browser, which displays results entries for all of the XPRT benchmarks in chronological order (see the screenshot below). You can filter the results by selecting a benchmark from the drop-down menu. You can also type values, such as a vendor name (e.g., Dell) or the name of a tech publication (e.g., PCWorld) into the free-form filter field. For results we’ve produced in our lab, clicking “PT” in the Source column takes you to a page with additional configuration information for the test system. For sources outside our lab, clicking the source name takes you to the original article or review that contains the result.

The second way to access our published results is by visiting the results page for an individual XPRT benchmark. Start by going to the page of the benchmark that interests you (e.g., CrXPRT.com) , and looking for the blue View Results button. Clicking the button takes you to a page that displays results for only that benchmark. You can use the free-form filter on the page to filter those results, and you can use the Benchmarks drop-down menu to jump to the other individual XPRT results pages.

The third way to view our results database is with the WebXPRT 4 results viewer. The viewer provides an information-packed, interactive tool with which you can explore data from the curated set of WebXPRT 4 results we’ve published on our site. We’ll discuss the features of the WebXPRT 4 results viewer in more detail in a future post.

You can use any of these approaches to compare the results of an XPRT on your device with our many published results. We hope you’ll take some time to explore the information in our results database and that it proves to be helpful to you. If you have ideas for new features or suggestions for improvement, we’d love to hear from you!

XPRT mentions in the tech press

Justin Greene
By Justin Greene
on April 4, 2024

One of the ways we monitor the effectiveness of the XPRT family of benchmarks is to regularly track XPRT usage and reach in the global tech press. Many tech journalists invest a lot of time and effort into producing thorough device reviews, and relevant and reliable benchmarks such as the XPRTs often serve as indispensable parts of a reviewer’s toolkit. Trust is hard-earned and easily lost in the benchmarking community, so we’re happy when our benchmarks consistently achieve “go-to” status for a growing number of tech assessment professionals around the world.

Because some of our newer readers may be unaware of the wide variety of outlets that regularly use the XPRTs, we occasionally like to share an overview of recent XPRT-related tech press activity. For today’s blog, we want to give readers a sampling of the press mentions we’ve seen over the past few months.

Recent mentions include:

Each month, we send out a BenchmarkXPRT Development Community newsletter that contains the latest updates from the XPRT world and provides a summary of the previous month’s XPRT-related activity, including new mentions of the XPRTs in the tech press. If you don’t currently receive the monthly BenchmarkXPRT newsletter but would like to join the mailing list, please let us know! There is no cost to join, and we will not publish or sell any of the contact information you provide. We will send only the monthly newsletter and occasional benchmark-related announcements, such as news about patches or new releases.

WebXPRT in PT reports

Mark Van Name
By Mark Van Name
on February 22, 2024

We don’t just make WebXPRT—we use it, too. If you normally come straight to BenchmarkXPRT.com or WebXPRT.com, you may not even realize that Principled Technologies (PT) does a lot more than just managing and administering the BenchmarkXPRT Development Community. We’re also the tech world’s leading provider of hands-on testing and related fact-based marketing services. As part of that work, we’re frequent WebXPRT users.

We use the benchmark when we test devices such as Chromebooks, desktops, mobile workstations, and consumer laptops for our clients. (You can see a lot of that work and many of our clients on our public marketing portfolio page.) We run the benchmark for the same reasons that others do—it’s a reliable and easy-to-use tool for measuring how well devices handle web browsing and other web work.

We also sometimes use WebXPRT simply because our clients request it. They request it for the same reason the rest of us like and use it: it’s a great tool. Regardless of job titles and descriptions, most laptop and tablet users surf the web and access web-based applications every day. Because WebXPRT is a browser benchmark, higher scores on it could indicate that a device may provide a superior online experience.

Here are just a few of the recent PT reports that used WebXPRT:

  • In a project for Dell, we compared the performance of a Dell Latitude 7340 Ultralight to that of a 13-inch Apple MacBook Air (2022).
  • In this study for HP, we compared the performance of an HP ZBook Firefly G10, an HP ZBook Power G10, and an HP ZBook Fury G10.
  • Finally, in a set of comparisons for Lenovo, we evaluated the system performance and end-user experience of eight Lenovo ThinkBook, ThinkCentre, and ThinkPad systems along with their Apple counterparts.

All these projects, and many more, show how a variety of companies rely on PT—and on WebXPRT—to help buyers make informed decisions. P.S. If we publish scores from a client-commissioned study in the WebXPRT 4 results viewer, we will list the source as “PT”, because we did the testing.
