WebXPRT can help you choose the right back-to-school tech

For many students, the excitement and anticipation of a new school year is right round the corner! In addition to being an opportunity to dive into new subjects, meet new people, and make progress toward learning goals, the back-to-school season often provides students and teachers with a chance to shop for new technology to meet their needs in the coming year. The tech marketplace can be confusing, however, with a slew of brands, options, and claims competing for back-to-school dollars.

Never fear: WebXPRT can help!

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

And in this age of AI, WebXPRT performance scores do account for specific AI tasks. The benchmark includes timed AI tasks in two workloads, which reflect the types of light browser-side inference tasks that are now quite common in consumer-oriented web applications and extensions. You can read more about that in previous blog entries on the “Organize Album using AI” and “Encrypt Notes and OCR Scan” workloads.

To see how devices stack up, the WebXPRT 4 results viewer is a good place to start. The viewer displays the WebXPRT 4 scores of over 975 devices—including many of the hottest new releases—and we’re adding more 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 way to find WebXPRT scores is to go directly to the tech press. If you’re considering a popular device, there’s a good chance that a recent tech review includes a WebXPRT score for that device. There are two quick ways to find these reviews: You can either (1) search for “WebXPRT” on a tech review site or (2) use a search engine and enter the device name and WebXPRT as search terms, such as “Lenovo ThinkPad X1 Carbon” and “WebXPRT.”

Here are a few recent articles and tech reviews that used WebXPRT:


If you’re excited about the opportunity to buy new tech for school, WebXPRT can provide you with the information you need to make 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. Feel free to contact us if you have any questions about WebXPRT or WebXPRT scores!

Notes from the lab: choosing a calibration system for MobileXPRT 3

Last week, we shared some details about what to expect in MobileXPRT 3. This week, we want to provide some insight into one part of the MobileXPRT development process, choosing a calibration system.

First, some background. For each of the benchmarks in the XPRT family, we select a calibration system using criteria we’ll explain below. This system serves as a reference point, and we use it to calculate scores that will help users understand a single benchmark result. The calibration system for MobileXPRT 2015 is the Motorola DROID RAZR M. We structured our calculation process so that the mean performance score from repeated MobileXPRT 2015 runs on that device is 100. A device that completes the same workloads 20 percent faster than the DROID RAZR M would have a performance score of 120, and one that performs the test 20 percent more slowly would have a score of 80. (You can find a more in-depth explanation of MobileXPRT score calculations in the Exploring MobileXPRT 2015 white paper.)

When selecting a calibration device, we are looking for a relevant reference point in today’s market. The device should be neither too slow to handle modern workloads nor so fast that it outscores most devices on the market. It should represent a level of performance that is close to what the majority of consumers experience, and one that will continue to be relevant for some time. This approach helps to build context for the meaning of the benchmark’s overall score. Without that context, testers can’t tell whether a score is fast or slow just by looking at the raw number. When compared to a well-known standard such as the calibration device, however, the score has more informative value.

To determine a suitable calibration device for MobileXPRT 3, we started by researching the most popular Android phones by market share around the world. It soon became clear that in many major markets, the Samsung Galaxy S8 ranked first or second, or at least appeared in the top five. As last year’s first Samsung flagship, the S8 is no longer on the cutting edge, but it has specs that many current mid-range phones are deploying, and the hardware should remain relevant for a couple of years.

For all of these reasons, we made the Samsung Galaxy S8 the calibration device for MobileXPRT 3. The model in our lab has a Qualcomm Snapdragon 835 SoC, 4 GB of RAM, and runs Android 7.0 (Nougat). We think it has the balance we’re looking for.

If you have any questions or concerns about MobileXPRT 3, calibration devices, or score calculations, please let us know. We look forward to sharing more information about MobileXPRT 3 as we get closer to the community preview.
