We’re excited to announce that the CrXPRT 2 Community Preview (CP) is now available! BenchmarkXPRT Development Community members can access the preview using a direct link posted on the CrXPRT tab in the XPRT Members’ Area (login required), where they will also find the CrXPRT 2 CP user manual.
You can find more information about the key differences between CrXPRT 2015 and CrXPRT 2 in last week’s blog entry. During the preview period, we allow testers to publish CP test scores, but CrXPRT 2 overall performance test scores and battery life measurements are not comparable to CrXPRT 2015 scores.
We appreciate everyone’s
patience and feedback during the CrXPRT 2 development process. We’re excited to
say that we’re now wrapping up some final details and expect to release the
Community Preview (CP) within the next week.
Here is a summary of the key
differences between CrXPRT 2015 and CrXPRT 2:
we mentioned a few weeks ago, CrXPRT 2 has a completely
new UI in line with the functional and aesthetic themes we used for the latest
versions of WebXPRT, MobileXPRT, and HDXPRT, with a focus on intuitive
CrXPRT 2 performance test includes six of the seven workloads in CrXPRT 2015.
Newer versions of Chrome can’t run the Photo Collage workload without a workaround, so we removed it from CrXPRT
updated the images in the Photo Effects and Face Detection workloads to reflect
more contemporary file resolutions and sizes.
CrXPRT 2 battery life test requires a full rundown, so you’ll need charge your device
to 100 percent before you can start the test, and the length of battery life
tests will vary according to the battery life of the systems under test.
no longer require testers to enter luminance and audio measurements in order to
run a battery life test.
added a second video playback segment to each battery life iteration.
allow testers to publish CP test scores, but CrXPRT 2 overall performance test scores
and battery life measurements are not comparable to CrXPRT 2015 scores.
Only BenchmarkXPRT Development Community members will be able to download the CrXPRT 2 CP. Because the Chrome team stopped providing search and browse functions for hosted and packaged Chrome apps in the Chrome Web Store, members will need a direct link to access the app. Once the app is available, we’ll post that link, along with the CrXPRT 2 CP user manual, on the CrXPRT tab in the XPRT Members’ Area (login required). We’ll also send a message to the community and post a notice here in the blog.
As we get
closer to the CrXPRT 2 Community Preview (CP), we want to provide readers with
a glimpse of the new CrXPRT 2 UI. In line with the functional and aesthetic themes
we used for the latest versions of WebXPRT, MobileXPRT, and HDXPRT, we’re
implementing a clean, bright look with a focus on intuitive navigation. The
screenshots below show how we’ve used that approach to rework the home, battery
life test, performance test, and battery life test results screens. (We’re
still tweaking the UI, so the screens you see in the CP may differ slightly.)
On the home screen, we kept the performance test and battery life test buttons, but made it clearer that you can choose only one. We also added a link to the user manual to the bottom ribbon for quick access.
If you choose to run a battery life test and click Next, the screen below appears. The CrXPRT 2 battery life test requires a full rundown, so you’ll need charge your device to 100 percent before you can start the test. Once you’ve done that, enter a name for the test run, unplug the system, and click Start. (Note that you no longer need to enter values for screen brightness and audio levels.)
The CrXPRT 2 performance test includes updated versions of six of the seven workloads in CrXPRT 2015. (As we discussed in a previous blog post, newer versions of Chrome can’t run the Photo Collage workload without a workaround, so we removed it from CrXPRT 2.) To run the performance test, enter a name for the test run, customize the workloads if you wish, and click Start.
For the results screens, we wanted to highlight the most important end-of-test information while still offering clear paths for options such as getting additional details on the test, submitting results, and running the test again. Below, we show the results screen from a battery life test. Note the “Main menu” link in the upper-left corner, which we added to all screens to give users a quick way to navigate back to the home screen.
CrXPRT 2 development
and testing are still underway. We don’t yet have an exact release date for the
CP, but once we do, we’ll announce it here in the blog.
Today, we want to let readers know what to expect from the XPRTs over the next several months. Timelines and details can always change, but we’re confident that community members will see CloudXPRT Community Preview (CP), updated AIXPRT, and CrXPRT 2 releases during the first half of 2020.
Bill shared some details about our new datacenter-oriented benchmark,
CloudXPRT. If you missed that post, we encourage you to check it out and learn more about the need for a new kind of cloud benchmark,
and our plans for the benchmark’s structure and metrics. We’re already testing preliminary
builds, and aim to release a CloudXPRT CP in late March, followed by a version
for general availability roughly two months later.
About a month ago, we explained how the number of moving parts in AIXPRT will necessitate a different development approach than we’ve used for other XPRTs. AIXPRT will require more frequent updating than our other benchmarks, and we anticipate releasing the second version of AIXPRT by mid-year. We’re still finalizing the details, but it’s likely to include the latest versions of ResNet-50 and SSD-MobileNet, selected SDK updates, ease-of-use improvements for the harness, and improved installation scripts. We’ll share more detailed information about the release timeline here in the blog as soon as possible.
As we mentioned in December, we’re working on CrXPRT 2, the next version of our
benchmark that evaluates the performance and battery life of Chromebooks. You
can find out more about how CrXPRT works both here in the blog and at CrXPRT.com.
currently testing an alpha version of CrXPRT 2. Testing is going well, but
we’re tweaking a few items and refining the new UI. We should start testing a
CP candidate in the next few weeks, and will have firmer information for
community members about a CP release date very soon.
We’re excited about these new developments and the prospect of extending the XPRTs into new areas. If you have any questions about CloudXPRT, AIXPRT, or CrXPRT 2, please feel free to ask!
We’re currently planning the next version of CrXPRT, our benchmark that evaluates the performance and battery life of Chromebooks. If you’re unfamiliar with CrXPRT, you can find out more about how it works both here in the blog and at CrXPRT.com. If you’ve used CrXPRT, we’d love to hear any suggestions you may have. What do you like or dislike about CrXPRT? What features do you hope to see in a new version?
When we begin work on a new version of any benchmark, one of our first steps is to determine whether the workloads will provide value during the years ahead. As technology and user behavior evolve, we update test content to be more relevant. One example is when we replace photos with ones that use more contemporary file resolutions and sizes.
Sometimes the changing tech landscape prompts us to remove entire workloads and add new ones. The Photo Collage workload in CrXPRT uses Portable Native Client (PNaCl) technology, for which the Chrome team will soon end support. CrXPRT 2015 has a workaround for this issue, but the best course of action for the next version of CrXPRT will be to remove this workload altogether.
The battery life test will also change. Earlier this year, we started to see unusual battery life estimates and high variance when running tests at CrXPRT’s default battery life test length of 3.5 hours, so we’ve been recommending that users perform full rundowns instead. In the next CrXPRT, the battery life test will require full rundowns.
We’ll also be revamping the CrXPRT UI to improve the look of the benchmark and make it easier to use, as we’ve done with the other recent XPRT releases.
We really do want to hear your ideas, and any feedback you send has a chance to shape the future of the benchmark. Let us know what you think!
From time to time, we remember that some XPRT users have experience with only one or two of the benchmark tools in our portfolio. They might have bookmarked a link to WebXPRT they found in a tech review or copied the HDXPRT installer package from a flash drive in their lab, but are unaware of other members of the XPRT family that could be useful to them. To spread the word on the range of capabilities the XPRTs offer, we occasionally highlight one of the XPRT tools in the blog . Last week, we discussed CrXPRT, a benchmark for evaluating the performance and battery life of Chrome OS devices. Today, we focus on TouchXPRT, our app for evaluating the performance of Windows 10 devices.
While our first benchmark, HDXPRT, is a great tool for assessing how well Windows machines handle media creation tasks using real commercial applications, it’s simply too large to run on most Windows tablets, 2-in-1s, and laptops with limited memory. To test those devices, we developed the latest version of TouchXPRT as a Universal Windows Platform app. As a Windows app, installing TouchXPRT is easy and quick (about 15 minutes). It runs five tests that simulate common photo, video, and music editing tasks; measures how quickly the device completes each of those tasks; and provides an overall score. It takes about 15 minutes to run on most devices. Labs can also automate testing using the command line or a script.
Check out the Exploring TouchXPRT 2016 white paper. In it, we discuss the TouchXPRT development process, its component tests and workloads, and how it calculates individual workload and overall scores. We also provide instructions for automated testing.
BenchmarkXPRT Development Community members also have access to the TouchXPRT source code, so consider joining the community today. There’s no obligation and membership is free for members of any company or organization with an interest in benchmarks.
If you’ve been looking for a Windows performance evaluation tool that’s easy to use and has the flexibility of a UWP app, give TouchXPRT a try and let us know what you think!
