Thinking ahead to the next HDXPRT

on November 12, 2020

We’re currently formulating our 2021 development roadmap for the XPRTs. In addition to planning CloudXPRT and WebXPRT updates, we’re discussing the possibility of releasing HDXPRT 5 in 2021. It’s hard for me to believe, but it’s been about two and a half years since we started work on HDXPRT 4, and February 2021 will mark two years since the first HDXPRT 4 release. Windows PCs are more powerful than ever, so it’s a good time to talk about how we can enhance the benchmark’s ability to measure how well the latest systems handle real-world media technologies and applications.

When we plan a new version of an XPRT benchmark, one of our first steps is updating the benchmark’s workloads so that they will remain relevant in years to come. We almost always update application content, such as photos and videos, to contemporary file resolutions and sizes. For example, we added both higher-resolution photos and a 4K video conversion task in HDXPRT 4. Are there specific types of media files that you think would be especially relevant to high-performance media tasks over the next few years?

Next, we will assess the suitability of the real-world trial applications that the editing photos, editing music, and converting videos test scenarios use. Currently, these are Adobe Photoshop Elements, Audacity, CyberLink MediaEspresso, and HandBrake. Can you think of other applications that belong in a high-performance media processing benchmark?

In HDXPRT 4, we gave testers the option to target a system’s discrete graphics card during the video conversion workload. Has this proven useful in your testing? Do you have suggestions for new graphics-oriented workloads?

We’ll also strive to make the UI more intuitive, to simplify installation, and to reduce the size of the installation package. What elements of the current UI do you find especially useful or think we could improve?

We welcome your answers to these questions and any additional suggestions or comments on HDXPRT 5. Send them our way!

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

By Justin Greene

on November 5, 2020

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!

A first look at the upcoming AIXPRT learning tool

By Justin Greene

on October 29, 2020

Last month, we announced that we’re working on a new AIXPRT learning tool. Because we want tech journalists, OEM lab engineers, and everyone who is interested in AIXPRT to be able to find the answers they need in as little time as possible, we’re designing this tool to serve as an information hub for common AIXPRT topics and questions.

We’re still finalizing aspects of the tool’s content and design, so some details may change, but we can now share a sneak peak of the main landing page. In the screenshot below, you can see that the tool will feature four primary areas of content:

The FAQ section will provide quick answers to the questions we receive most from testers and the tech press.
The AIXPRT basics section will describe specific topics such as the benchmark’s toolkits, networks, workloads, and hardware and software requirements.
The testing and results section will cover the testing process, the metrics the benchmark produces, and how to publish results.
The AI/ML primer will provide brief, easy-to-understand definitions of key AI and ML terms and concepts for those who want to learn more about the subject.

We’re excited about the new AIXPRT learning tool, and will share more information here in the blog as we get closer to a release date. If you have any questions about the tool, please let us know!

Following up with MobileXPRT 3 on Android 11

By Justin Greene

on October 22, 2020

As we discussed last week, we’ve learned that MobileXPRT 3 is crashing after installation on some Android 11 phones. We now know what is causing this behavior: changes to the storage strategy and permissions requirements in Android 11. The new file storage strategy is called scoped storage. By default, scoped storage restricts an app’s storage access to app-specific directories and media, and prohibits general access to external or public directories. This default setting requires an opt-in permissions prompt that MobileXPRT 3 does not currently have. It also prevents third-party apps such as email clients or file managers from being accessing MobileXPRT 3 results files.

To fix this, we are planning to rebuild MobileXPRT 3 to (1) point all of the benchmark’s file references to its private directory, and (2) allow users to zip results files and attach them to results submission emails. While we do not expect that either of these changes will affect performance results, we’ll perform testing to confirm this before we publish the new build.

We don’t expect these changes to take too long, and will keep you updated here in the blog. If you have any questions about the update process or MobileXPRT 3, please let us know!

New MobileXPRT 3 installations may crash on Android 11

By Justin Greene

on October 15, 2020

We recently received a tech support inquiry about problems with new MobileXPRT 3 installations on some Android 11 phones. The tester installed MobileXPRT 3 on a selection of phones running Android 11, and the app crashed immediately upon opening. We were able to reproduce the issue on multiple phones in our lab, and currently know that the issue may happen on the Google Pixel 3, Google Pixel 4a 5G, Google Pixel 4XL, Google Pixel 5, and the OnePlus 8T (running Android 11 with an Oxygen OS skin).

MobileXPRT 3 continues to run without issues on Android 9 and 10 phones. When we updated an Android 10 phone with an existing MobileXPRT 3 installation to Android 11, we found that the benchmark ran successfully. This suggests a lack of fundamental incompatibilities between MobileXPRT 3 and current versions of Android 11. Because some of our lab techs experienced crashes immediately after the app asked for permissions, we think it’s possible that new permissions-setting requirements in Android 11 are causing the problem.

We’re currently working to isolate the problem and identify a course of action. We’ll share more information here in the blog as soon as possible. If you’ve encountered this problem in your testing, we apologize for the inconvenience, and we’re thankful for your patience as we work towards a solution.

If you have any information you’d like to share about running MobileXPRT 3 on Android 11, please let us know!

Next up: a white paper about the CloudXPRT data analytics workload

By Justin Greene

on October 8, 2020

Soon, we’ll be publishing a CloudXPRT white paper that focuses on the benchmark’s data analytics workload. We summarized the workload in the Introduction to CloudXPRT white paper, but in the same way that the Overview of the CloudXPRT Web Microservices Workload paper did, the new paper will discuss the workload in much greater detail.

In addition to providing practical information about the installation package and minimum system requirements for the data analytics workload, the paper will describe test configuration variables, structural components, task workflows, and test metrics. It will also include guidance on interpreting test results and submitting them for publication.

As we’ve noted, CloudXPRT is one of the more complex tools in the XPRT family, with no shortage of topics to explore. Possible future topics include the impact of adjusting specific test configuration options, recommendations for results reporting, and methods for results analysis. If there are specific topics that you’d like us to address in future white papers, please feel free to send us your ideas!

We hope that the upcoming Overview of the CloudXPRT Data Analytics Workload paper will serve as a go-to resource for CloudXPRT testers, and will answer any questions you have about the workload. Once it goes live, we’ll provide links in the Helpful Info box on CloudXPRT.com and the CloudXPRT section of our XPRT white papers page.

If you have any questions, please let us know!
