Sneak a peek at HDXPRT 4

on August 23, 2018

A few months ago, we shared some details about HDXPRT 4 development progress. Now that we’re closer to releasing a community preview build, we wanted to offer a sneak peek at the new benchmark. We may still tweak a few things during pre-release testing, but we’re close to the final look.

Below, you can see the benchmark’s new start page. After installation and completing a few brief pre-test configuration steps, running HDXPRT 4 is as easy as entering a test name and clicking the start button.

During the test, you’ll see HDXPRT’s real-world trial applications such as Adobe Photoshop Elements and CyberLink Media Espresso open and close during each iteration, though you won’t see workload graphics within the HDXPRT UI harness. When the test finishes, the results screen pops up. As you can see below, the results screen displays the overall and individual workload category scores in a straightforward and easy-to-understand manner. Below the workload scores, a button provides access to additional test and system information.

We’re not yet ready to share a date for the community preview, but we’ll provide more information in the coming weeks. As always, XPRT community previews are only available to BenchmarkXPRT Development Community members. If you’re interested in testing the HDXPRT 4 Community Preview, we invite you to join the community now. If you have any questions or comments about HDXPRT or the community, please contact us.

AI and the next MobileXPRT

By Justin Greene

on August 16, 2018

As we mentioned a few weeks ago, we’re in the early planning stages for the next version of MobileXPRT—MobileXPRT 3. We’re always looking for ways to make XPRT benchmark workloads more relevant to everyday users, and a new version of MobileXPRT provides a great opportunity to incorporate emerging tech such as AI into our apps. AI is everywhere and is beginning to play a huge role in our everyday lives through smarter-than-ever phones, virtual assistants, and smart homes. The challenge for us is to identify representative mobile AI workloads that have the necessary characteristics to work well in a benchmark setting. For MobileXPRT, we’re researching AI workloads that have the following characteristics:

They work offline, not in the cloud.
They don’t require additional training prior to use.
They support common use cases such as image processing, optical character recognition (OCR), etc.

We’re researching the possibility of using Google’s Mobile Vision library, but there may be other options or concerns that we’re not aware of. If you have tips for places we should look, or ideas for workloads or APIs we haven’t mentioned, please let us know. We’ll keep the community informed as we narrow down our options.

MWCS18 and AIXPRT: a new video

By Justin Greene

on July 12, 2018

A few weeks ago, Bill shared his first impressions from this year’s Mobile World Congress Shanghai (MWCS). “5G +” was the major theme, and there was a heavy emphasis on 5G + AI. This week, we published a video about Bill’s MWCS experience and the role that the XPRTs can play in evaluating emerging technologies such as 5G, AI, and VR. Check it out!

You can read more about AIXPRT development here. We’re still accepting responses to the AIXPRT Request for Comments, so if you would like to share your ideas on developing an AI/machine learning benchmark, please feel free to contact us.

Which browser is the fastest? It’s complicated.

By Justin Greene

on July 5, 2018

PCWorld recently published the results of a head-to-head browser performance comparison between Google Chrome, Microsoft Edge, Mozilla Firefox, and Opera. As we’ve noted about similar comparisons, no single browser was the fastest in every test. Browser speed sounds like a straightforward metric, but the reality is complex.

For the comparison, PCWorld used three JavaScript-centric test suites (JetStream, SunSpider, and Octane), one benchmark that simulates user actions (Speedometer), a few in-house tests of their own design, and one benchmark that simulates real-world web applications (WebXPRT). Edge came out on top in JetStream and SunSpider, Opera won in Octane and WebXPRT, and Chrome had the best results in Speedometer and PCWorld’s custom workloads.

The reason that the benchmarks rank the browsers so differently is that each one has a unique emphasis and tests a specific set of workloads and technologies. Some focus on very low-level JavaScript tasks, some test additional technologies such as HTML5, and some are designed to identify strengths or weakness by stressing devices in unusual ways. These approaches are all valid, and it’s important to understand exactly what a given score represents. Some scores reflect a very broad set of metrics, while others assess a very narrow set of tasks. Some scores help you to understand the performance you can expect from a device in your everyday life, and others measure performance in scenarios that you’re unlikely to encounter. For example, when Eric discussed a similar topic in the past, he said the tests in JetStream 1.1 provided information that “can be very useful for engineers and developers, but may not be as meaningful to the typical user.”

As we do with all the XPRTs, we designed WebXPRT to test how devices handle the types of real-world tasks consumers perform every day. While lab techs, manufacturers, and tech journalists can all glean detailed data from WebXPRT, the test’s real-world focus means that the overall score is relevant to the average consumer. Simply put, a device with a higher WebXPRT score is probably going to feel faster to you during daily use than one with a lower score. In today’s crowded tech marketplace, that piece of information provides a great deal of value to many people.

What are your thoughts on browser testing? We’d love to hear from you.

A note about a recent CrXPRT update

By Justin Greene

on June 21, 2018

A tester from Acer recently contacted us about an issue where CrXPRT was freezing indefinitely during the Photo Effects workload. We initially thought the problem was limited to a specific hardware platform or Chrome OS version, but soon discovered the issue was affecting all CrXPRT tests, regardless of the system.

After quite a bit of troubleshooting, we were able to find and fix what turned out to be simple bug. The problem started with a change we made to increase security and strengthen compliance with GDPR by moving all our web pages to HTTPS. Specifically, we added a redirect that forced principledtechnologies.com to www.principledtechnologies.com. Chrome apps have a manifest property that defines which websites can connect to the application. Because we hadn’t reconfigured the CrXPRT path permissions to account for the new redirect, the test failed. We made the necessary edits to the manifest, tested the fix, and uploaded the updated package (build number 1.0.2.1) to the Chrome Web Store.

If you’re still encountering this problem during testing, check to be sure the app has updated on your system. The changes we made do not affect performance, and all completed CrXPRT test scores from before and after the update are valid and comparable.

We’re grateful whenever community members report issues! If you ever have any problems, questions, or comments regarding any of the XPRTs, please feel free to contact us.

WebXPRT passes another milestone!

By Justin Greene

on June 14, 2018

We’re excited to see that users have successfully completed over 250,000 WebXPRT runs! From the original WebXPRT 2013 to the most recent version, WebXPRT 3, this tool has been popular with manufacturers, developers, consumers, and media outlets around the world because it’s easy to run, it runs quickly and on a wide variety of platforms, and it evaluates device performance using real-world tasks.

If you’ve run WebXPRT in any of the more than 458 cities and 64 countries from which we’ve received complete test data—including newcomers Lithuania, Luxembourg, Sweden, and Uruguay—we’re grateful for your help in reaching this milestone. Here’s to another quarter-million runs!

If you haven’t yet transitioned your browser testing to WebXPRT 3, now is a great time to give it a try! WebXPRT 3 includes updated photo workloads with new images and a deep learning task used for image classification. It also uses an optical character recognition task in the Encrypt Notes and OCR scan workload and combines part of the DNA Sequence Analysis scenario with a writing sample/spell check scenario to simulate online homework in the new Online Homework workload. Users carry out tasks like these on their browsers daily, making these workloads very effective for assessing how well a device will perform in the real world.

Happy testing to everyone, and if you have any questions about WebXPRT 3 or the XPRTs in general, feel free to ask!
