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

on August 7, 2025

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:

Tom’s Guide used WebXPRT 4 to evaluate the Acer Chromebook Plus 515 in an article titled, “Best AI laptop for 2025—tested and rated.”
Laptop Mag used WebXPRT 4 as a part of the suite of benchmarks that they used to assess devices for an article titled, “Best touchscreen laptops in 2025: 6 tested and reviewed.”
Notebookcheck used WebXPRT in reviews of the ASUS ExpertBook B5, Apple MacBook Air 13 M4, Dell 14 Plus 2-in-1, HP EliteBook X G1i 14 AI, Lenovo ThinkPad E14 G7, Microsoft Surface Pro 12, and Samsung Galaxy Tab S10 FE+ tablet, among many others.

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!

Web AI frameworks: Possible paths for the AI-focused WebXPRT 4 auxiliary workload

By Justin Greene

on September 5, 2024

A few months ago, we announced that we’re moving forward with the development of a new auxiliary WebXPRT 4 workload focused on local, browser-side AI technology. Local AI has many potential benefits, and it now seems safe to say that it will be a common fixture of everyday life for many people in the future. As the growth of browser-based inference technology picks up steam, our goal is to equip WebXPRT 4 users with the ability to quickly and reliably evaluate how well devices can handle substantial local inference tasks in the browser.

To reach our goal, we’ll need to make many well-researched and carefully considered decisions along the development path. Throughout the decision-making process, we’ll be balancing our commitment to core XPRT values, such as ease of use and widespread compatibility, with the practical realities of working with rapidly changing emergent technologies. In today’s blog, we’re discussing one of the first decision points that we face—choosing a Web AI framework.

AI frameworks are suites of tools and libraries that serve as building blocks for developers to create new AI-based models and apps or integrate existing AI functions in custom ways. AI frameworks can be commercial, such as OpenAI, or open source, such as Hugging Face, PyTorch, and TensorFlow. Because the XPRTs are available at no cost for users and we publish our source code, open-source frameworks are the right choice for WebXPRT.

Because the new workload will focus on locally powered, browser-based inference tasks, we also need to choose an AI framework that has browser integration capabilities and does not rely on server-side computing. These types of frameworks—called Web AI—use JavaScript (JS) APIs and other web technologies, such as WebAssembly and WebGPU, to run machine learning (ML) tasks on a device’s CPU, GPU, or NPU.

Several emerging Web AI frameworks may provide the compatibility and functionality we need for the future WebXPRT workload. Here are a few that we’re currently researching:

ONNX Runtime Web: Microsoft and other partners developed the Open Neural Network Exchange (ONNX) as an open standard for ML models. With available tools, users can convert models from several AI frameworks to ONNX, which can then be used by ONNX Runtime Web. ONNX Runtime Web allows developers to leverage the broad compatibility of ONNX-formatted ML models—including pre-trained vision, language, and GenAI models—in their web applications.
Transformers.js: Transformers.js, which uses ONNX Runtime Web, is a JS library that allows users to run AI models from the browser and offline. Transformers.js supports language, computer vision, and audio ML models, among others.
MediaPipe: Google developed MediaPipe as a way for developers to adapt TensorFlow-based models for use across many platforms in real-time on-device inference applications such as face detection and gesture recognition. MediaPipe is particularly useful for inference work in images, videos, and live streaming.
TensorFlow.js: TensorFlow has been around for a long time, and the TensorFlow ecosystem provides users with a broad variety of models and datasets. TensorFlow is an end-to-end ML solution—training to inference—but with available pre-trained models, developers can focus on inference. TensorFlow.js is an open-source JS library that helps developers integrate TensorFlow with web apps.

We have not made final decisions about a Web AI framework or any aspect of the future workload. We’re still in the research, discussion, and experimentation stages of development, but we want to be transparent with our readers about where we are in the process. In future blog posts, we’ll discuss some of the other major decision points in play.

Most of all, we invite you to join us in these discussions, make recommendations, and give us any other feedback or suggestions you may have, so please feel free to share your thoughts!

on August 8, 2024

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:

The evolving PC market brings new opportunities for WebXPRT

By Justin Greene

on December 7, 2023

Here at the XPRTs, we have to spend time examining what’s next in the tech industry, because the XPRTs have to keep up with the pace of innovation. In our recent discussions about 2024, a major recurring topic has been the potential impact of Qualcomm’s upcoming line of SOCs designed for Windows on Arm PCs.

Now, Windows on Arm PCs are certainly not new. Since Windows RT launched on the Arm-based Microsoft Surface RT in 2012, various Windows on Arm devices have come and gone, but none of them—except for some Microsoft SQ-based Surface devices—have made much of a name for themselves in the consumer market.

The reasons for these struggles are straightforward. While Arm-based PCs have the potential to offer consumers the benefits of excellent battery life and “always-on” mobile communications, the platform has historically lagged Intel- and AMD-based PCs in performance. Windows on Arm devices have also faced the challenge of a lack of large-scale buy-in from app developers. So, despite the past involvement of device makers like ASUS, HP, Lenovo, and Microsoft, the major theme of the Windows on Arm story has been one of very limited market acceptance.

Next year, though, the theme of that story may change. If it does, WebXPRT 4 is well-positioned to play an important part.

At the recent Qualcomm Technology Summit, the company unveiled the new 4nm Snapdragon X Elite SOC, which includes an all-new 12-core Oryon CPU, an integrated Adreno GPU, and an integrated Hexagon NPU (neural processing unit) designed for AI-powered applications. Company officials presented performance numbers that showed the X Elite surpassing the performance of late-gen AMD, Apple, and Intel competitor platforms, all while using less power.

Those are massive claims, and of course the proof will come—or not—only when systems are available for test. (In the past, companies have made similar claims about Windows on Arm advantages, only to see those claims evaporate by the time production devices show up on store shelves.)

Will Snapdragon X Elite systems demonstrate unprecedented performance and battery life when they hit the market? How will the performance of those devices stack up to Intel’s Meteor Lake systems and Apple’s M3 offerings? We don’t yet know how these new devices may shake up the PC market, but we do know that it looks like 2024 will present us with many golden opportunities for benchmarking. Amid all the marketing buzz, buyers everywhere will want to know about potential trade-offs between price, power, and battery life. Tech reviewers will want to dive into the details and provide useful data points, but many traditional PC benchmarks simply won’t work with Windows on ARM systems. As a go-to, cross-platform favorite of many OEMs—that runs on just about anything with a browser—WebXPRT 4 is in a perfect position to provide reviewers and consumers with relevant performance comparison data.

It’s quite possible that 2024 may be the biggest year for WebXPRT yet!

The holiday shopping season is fast approaching, and choosing the right tech gift can often be a daunting task. If you’re considering phones, tablets, Chromebooks, or laptops as gifts, and are unsure where to get reliable device information, the XPRTs can help!

The XPRTs provide objective, reliable measures of a device’s performance that can help to cut through the marketing noise. For example, instead of guessing whether the performance of a new laptop lives up to its billing, you can use its WebXPRT performance score to see how it stacks up against the competition on everyday tasks.

A good place to start looking for device scores is our XPRT results browser, which lets you access our database of more than 3,200 test results from over 165 sources, including major tech review publications around the world, OEMs, and independent testers. You can find a wealth of current and historical performance data across all the XPRT benchmarks and hundreds of devices. Learn how to use the results browser here.

If you’re considering a popular device, chances are good that a recent tech review includes an XPRT score for it. You can find these reviews by going to your favorite tech review site and searching for “XPRT,” or entering 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:

AnandTech used WebXPRT to evaluate the MSI Titan GT77 gaming laptop.
Notebookcheck used WebXPRT in reviews of the Apple iPhone 14 Plus, the ASUS ZenFone 9, Google Pixel 6a, and the Samsung Galaxy Z Fold4 5G.
Tom’s Guide used WebXPRT to test the Apple MacBook Pro (M1 2022).
PCMag used WebXPRT to evaluate the Apple MacBook Air (M2 20022) and Lenovo Legion 7 Gen 7 laptops.
PCWorld used WebXPRT in a review of the Microsoft Surface Pro 9.

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!

A note about WebXPRT 4 and Internet Explorer

By Justin Greene

on February 10, 2022

During some recent internal WebXPRT 4 Preview testing, we discovered that the WebXPRT 4 Preview does not run in Internet Explorer (IE) 11. In fact, before the first workload begins in IE, the WebXPRT 4 built-in WebAssembly (WASM) check fails and produces an error message.

The reason we haven’t tested WebXPRT 4 on IE 11 before now is that Internet Explorer is currently in its end-of-life phase. Microsoft has been removing support for IE 11 in Microsoft 365 and other apps for some time, they did not include the desktop version of IE 11 in Windows 11, and they are removing support for IE 11 in Windows 10 on June 15, 2022. Among Windows users, the most popular browsers are now Microsoft Edge, Google Chrome, and Mozilla Firefox.

We’re proud that WebXPRT has historically had broad, cross-platform compatibility in almost any browser. However, the modern web is rapidly incorporating powerful tools such as WASM that do not work in older legacy browsers. To maintain the benchmark’s relevance in future years, we need to deprioritize some level of legacy compatibility, and this begins with WebXPRT 4 release.

For the WebXPRT testers who wish to continue testing with IE 11, WebXPRT 3 will remain on our site for the foreseeable future. Barring any further changes from Microsoft, the benchmark should continue to run in existing instances of the Internet Explorer desktop app.

The official WebXPRT 4 launch is approaching, and we hope to announce the release date within the next few weeks! Until that time, we will continue to share the latest updates here in the blog. If you have any questions or comments about WebXPRT 4 or compatibility with legacy browsers, please feel free to contact us!
