More than Chromebooks

Recently, we got a question from AnandTech asking how hard it would be to get CrXPRT to run on Chrome on Windows.

The short answer is that getting it to run isn’t difficult. However, as we have written about many times in the past, it’s not enough for a benchmark to simply run on a device. The results it produces must be comparable. Even if the benchmark appears to run identically, small differences in timers or how the platform reports its state can have a big impact.

To date, we have been dealing only with Chromebooks of various flavors. However, we’re now testing CrXPRT on a much wider range of devices. The results are generally looking reasonable, although we’re finding some minor issues. For example, the battery information isn’t as granular on some devices as it is on Chromebooks.

As soon as we are sure that CrXPRT is returning reasonable results on the new classes of devices, you’ll be the first to know!

In other news, we’re planning to remove TouchXPRT 2013 from the Windows Store on February 16. We wanted to have a period of overlap with TouchXPRT 2014 to allow labs time to transition. It’s been over 6 months, and we feel this is a good time. TouchXPRT 2013 will remain available in the members’ area of the BenchmarkXPRT.com Web site.

So easy a child can do it!

Tomorrow we are releasing a new video featuring CrXPRT. This one is set in a school science fair, where “Ellie Smith” explains how she used CrXPRT to help her school decide which Chromebook to buy. We were lucky enough to get a thoroughly professional and charming young actress to play the role of Ellie. (I have a tiny cameo as the guy in the gray sport coat at the back of the room.)

Before we started shooting the video, we asked an actual 10-year-old to install and run CrXPRT. I hate to sound like an old commercial, but it really was so simple that a child could do it!

We also created a faux science report to go with the video. An adult—not a sixth-grader—wrote the report, but the results in it and in the video are real. (You can follow the links in the science report to see the real-world results online.)

When it goes live, you’ll find the video and the report on CrXPRT.com, as well as on YouTube and SlideShare. We hope you’ll enjoy seeing Ellie’s project!

The busiest year ever!

As 2014 winds down, it’s a good time to look back at the year. And what a year it has been! This is the year that the XPRTs really went global. The benchmarks are in wider use than ever. The community continues to grow.

Here are a few of the big things that happened this year:

 

It’s going to be hard to top this year, but we are certainly going to try! There’s another video coming soon. We’re already working on WebXPRT 2015. (If you haven’t commented on the WebXPRT 2015 design document yet, it’s not too late.) We’re making plans for MWC 2015. And there’s a lot more in the works!

Whatever your traditions are, we hope you have a wonderful holiday season. See you in 2015.

CrXPRT 2015 is here!

Today, we’re releasing CrXPRT 2015, our benchmark for evaluating the performance and battery life of Chrome OS devices. The BenchmarkXPRT Development Community has been using community previews for several weeks, but now that we’ve released the benchmark, anyone can download CrXPRT and publish results.

Download CrXPRT 2015 from the Chrome Web Store

You can read more about CrXPRT in the CrXPRT 2015 User Manual located here. The User Manual also explains how to configure your device for testing and discusses the options that are available to you.

After trying out CrXPRT, please send your comments to BenchmarkXPRTsupport@principledtechnologies.com.

Today is the day!

We release CrXPRT 2015 to the public later today. Many thanks to all the community members who’ve used the community previews for all their help. CrXPRT will be available in the Chrome Web Store, but for now, it will not be available as a direct download from the CrXPRT page. We’re looking into ways to host a direct download on our site, and hope to have a solution after the first of the year. If you’re having problems getting CrXPRT from the store, the community previews will still be available in the members’ area.

If you are new to testing in a Chrome environment, be aware of some things. One is that a Chromebook will check for updates every time it reboots. If you’re running multiple tests, be sure to not reboot the system, or it may upgrade the operating system between your tests.

For those testing multiple devices, it’s a good idea to use a separate account for each device. If you have multiple Chromebooks logged into the same account, Chrome OS will sync all devices. This could be useful in some circumstances, but it could be a problem at other times.

We are very excited about the release. Let us know what you think!

Timing is everything

Eric Hale

on December 11, 2014

We have a couple instances of interesting timing this week.

A few weeks ago, we released the second community preview for CrXPRT (CP2).  It’s been doing very well and we’re planning to release CrXPRT to the public next week. Many thanks to all the community members who have helped make this possible.

Because the release is so close to the end of the year, the general release will be CrXPRT 2015. However, the community previews were dated 2014, which is potentially confusing. We want to reassure you that the results will still be comparable. As we discussed last week, for any of the XPRT benchmarks, the results from the community previews are always comparable to those from the final release.

In other news, we fixed the intermittent problem BatteryXPRT was having on the Nexus 9. The tests are looking good. In a bit of really good timing, this week Google started rolling out Android 5.01. We will be going back and retesting the devices with the newer version of the OS. We don’t expect any new problems, but it’s very nice that we got to check it out before we released the patch.
