Considering WebAssembly for WebXPRT 4

Earlier this month, we discussed a few of our ideas for possible changes in WebXPRT 4, including new web technologies that may work well in a browser benchmark. Today, we’re going to focus on one of those technologies, WebAssembly, in more detail.

WebAssembly (WASM) is a binary instruction format that works across all modern browsers. WASM provides a sandboxed environment that operates at native speeds and takes advantage of common hardware specs across platforms. WASM’s capabilities offer web developers a great deal of flexibility for running complex client applications in the browser. That level of flexibility may enable workload scenario options for WebXPRT 4 such as gaming, video editing, VR, virtual machines, and image recognition. We’re excited about those possibilities, but it remains to be seen which WASM use cases will meet the criteria we look for when considering new WebXPRT workloads, such as relevancy to real life, consistency and replicability, and the broadest-possible level of cross-browser support.

One WASM workload that we’re investigating is a web-based machine learning workload with TensorFlow for JavaScript (TensorFlow.js). TensorFlow.js offers pre-trained models for a wide variety of tasks, including image classification, object detection, sentence encoding, and natural language processing. TensorFlow.js originally used WebGL technology on the back end, but now it’s possible to run the workload using WASM. We could also use this technology to enhance one of WebXPRT’s existing AI-themed workloads, such as Organize Album using AI or Encrypt Notes and OCR Scan.

We’re can’t yet say that a WASM workload will definitely appear in WebXPRT 4, but the technology is promising. Do you have any experience with WASM, or ideas for WASM workloads? There’s still time for you to help shape the future of WebXPRT 4, so let us know what you think!

Moving forward with WebXPRT 4

In the coming months, we’ll be moving forward with the first stages of the WebXPRT 4 development process. It’s been a while since we last asked readers to send their thoughts about web technologies and workloads that may be a good fit for WebXPRT 4, but we’re still very much open to ideas. If you missed our previous posts about possible changes for WebXPRT 4, we recap the most prominent ideas below. We also request specific feedback regarding a potential battery life component.

  • Community members have asked about a WebXPRT 4 battery life test. Any such test would likely be very similar to the performance-weighted battery life test in CrXPRT 2 (as opposed to a simple rundown test). While WebXPRT runs in almost any browser, cross-browser compatibility issues could cause a WebXPRT battery life test to run in only one browser. If this turned out to be the case, would you still be interested in using the battery life test? Please let us know.
  • One of the most promising ideas is the potential addition of one or more WebAssembly (WASM) workloads. WASM is a low-level, binary instruction format that works across all modern browsers. It offers web developers a great deal of flexibility and provides the speed and efficiency necessary for running complex client applications in the browser. WASM enables a variety of workload scenario options, including gaming, video editing, VR, virtual machines, image recognition, and interactive educational content.
  • We are also considering adding a web-based machine learning workload with TensorFlow for JavaScript (TensorFlow.js). TensorFlow.js offers pre-trained models for a wide range of tasks including image classification, object detection, sentence encoding, and natural language processing. We could also use this technology to enhance one of WebXPRT’s existing AI-themed workloads, such as Organize Album using AI or Encrypt Notes and OCR Scan.
  • Other ideas include using a WebGL-based workload to target GPUs, and simulating common web applications.

We’ll start work on WebXPRT 4 soon, but there’s still time to send your comments and ideas, so please do so as quickly as possible!

The XPRTs can help with your holiday shopping

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:


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!

Using WebXPRT 3 to compare the performance of popular browsers (Round 2)

It’s been nine months since we’ve published a WebXPRT 3 browser performance comparison, so we decided to put the newest versions of popular browsers through the paces to see if the performance rankings have changed since our last round of tests.

We used the same laptop as last time: a Dell XPS 13 7930 with an Intel Core i3-10110U processor and 4 GB of RAM running Windows 10 Home, updated to version 1909 (18363.1139). We installed all current Windows updates and tested on a clean system image. After the update process completed, we turned off updates to prevent them from interfering with test runs. We ran WebXPRT 3 three times on five browsers: Brave, Google Chrome, Microsoft Edge, Mozilla Firefox, and Opera. The posted score for each browser is the median of the three test runs.

In our last round of tests, the four Chromium-based browsers (Brave, Chrome, Edge, and Opera) produced scores that were nearly identical. Only Mozilla Firefox produced a significantly different (and better) score. The parity of the Chromium-based browsers was not surprising, considering they have the same underlying foundation.

In this round of testing, the Chromium-based browsers again produced very close scores, although Brave’s performance lagged by about 4 percent. Firefox again separated itself from the pack with a higher score. With the exception of Chrome, which produced an identical score as last time, every browser’s score was slightly slower than before. There are many possible reasons for this, including increased overhead in the browsers or changes in Windows, and the respective slowdowns for each browser will probably be unnoticeable to most users during everyday tasks.

Do these results mean that Mozilla Firefox will provide you with a speedier web experience? As we noted in the last comparison, a device with a higher WebXPRT score will probably feel faster during daily use than one with a lower score. For comparisons on the same system, however, the answer depends in part on the types of things you do on the web, how the extensions you’ve installed affect performance, how frequently the browsers issue updates and incorporate new web technologies, and how accurately each browsers’ default installation settings reflect how you would set up that browser for your daily workflow.

In addition, browser speed can increase or decrease significantly after an update, only to swing back in the other direction shortly thereafter. OS-specific optimizations can also affect performance, such as with Edge on Windows 10 and Chrome on Chrome OS. All of these variables are important to keep in mind when considering how browser performance comparison results translate to your everyday experience.

What are your thoughts on browser performance? Let us know!

WebXPRT 3: relevant, reliable, and easy to use

WebXPRT continues to be the most widely-used XPRT benchmark, with just over 625,000 runs to date. From the first WebXPRT release in 2013, WebXPRT has been popular with device manufacturers, developers, tech journalists, and consumers because it’s easy to run, it runs on almost anything with a web browser, and its workloads reflect the types of web-based tasks that people are likely to encounter on a daily basis.

We realize that many folks who follow the XPRTs may be unaware of the wide variety of WebXPRT uses that we frequently read about in the tech press. Today, we thought it would be interesting to bring the numbers to life. In addition to dozens of device reviews, here’s a sample of WebXPRT 3 mentions over the past few weeks.

As we plan for the next version of WebXPRT, we want to be sure we build a benchmark that continues WebXPRT’s legacy of relevant workloads, ease-of-use, and broad compatibility. We know what works well in our lab, but to build a benchmark that meets the needs of a diverse group of users all around the world, it’s important that we hear from all types of testers. We recently discussed some of the new technologies that we’re considering for WebXPRT 4, so please don’t hesitate to let us know what you think about those proposals, or send any additional ideas you may have!

Potential web technology additions for WebXPRT 4

A few months ago, we invited readers to send in their thoughts and ideas about web technologies and workload scenarios that may be a good fit for the next WebXPRT. We’d like to share a few of those ideas today, and we invite you to continue to send your feedback. We’re approaching the time when we need to begin firming up plans for a WebXPRT 4 development cycle in 2021, but there’s still plenty of time for you to help shape the future of the benchmark.

One of the most promising ideas for WebXPRT 4 is the potential addition of one or more WebAssembly (WASM) workloads. WASM is a low-level, binary instruction format that works across all modern browsers. It offers web developers a great deal of flexibility and provides the speed and efficiency necessary for running complex client applications in the browser. WASM enables a variety of workload scenario options, including gaming, video editing, VR, virtual machines, image recognition, and interactive educational content.

In addition, the Chrome team is dropping Portable Native Client (PNaCL) support in favor of WASM, which is why we had to remove a PNaCL workload when updating CrXPRT 2015 to CrXPRT 2. We generally model CrXPRT workloads on existing WebXPRT workloads, so familiarizing ourselves with WASM could ultimately benefit more than one XPRT benchmark.

We are also considering adding a web-based machine learning workload with TensorFlow for JavaScript (TensorFlow.js). TensorFlow.js offers pre-trained models for a wide variety of tasks including image classification, object detection, sentence encoding, natural language processing, and more. We could also use this technology to enhance one of WebXPRT’s existing AI-themed workloads, such as Organize Album using AI or Encrypt Notes and OCR Scan.

Other ideas include using a WebGL-based workload to target GPUs and investigating ways to incorporate a battery life test. What do you think? Let us know!
