Transparent goals

Recently, Forbes published an article discussing a new report on phone battery life from Which?, a UK consumer advocacy group. In the report, Which? states that they tested the talk time battery life of 50 phones from five brands. During the tests, phones from three of the brands lasted longer than the manufacturers’ claims, while phones from another brand underperformed by about five percent. The fifth brand’s published battery life numbers were 18 to 51 percent higher than Which? recorded in their tests.

Folks can read the article for more details about the tests and the brands. While the report raises some interesting questions, and the article provides readers with brief test methodology descriptions from Which? and one manufacturer, we don’t know enough about the tests to say which set of claims is correct. Any number of variables related to test workloads or device configuration settings could significantly affect the results. Both parties may be using sound benchmarking principles in good faith, but their test methodologies may not be comparable. As it is, we simply don’t have enough information to evaluate the study.

Whether the issue is battery life or any other important device spec, information conflicts, such as the one that the Forbes article highlights, can leave consumers scratching their heads, trying to decide which sources are worth listening to. At the XPRTs, we believe that the best remedy for this type of problem is to provide complete transparency into our testing methodologies and development process. That’s why our lab techs verify all the hardware specs for each XPRT Weekly Tech Spotlight entry. It’s why we publish white papers explaining the structure of our benchmarks in detail, as well as how the XPRTs calculate performance results. It’s also why we employ an open development community model and make each XPRT’s source code available to community members. When we’re open about how we do things, it encourages the kind of honest dialogue between vendors, journalists, consumers, and community members that serves everyone’s best interests.

If you love tech and share that same commitment to transparency, we’d love for you to join our community, where you can access XPRT source code and previews of upcoming benchmarks. Membership is free for anyone with a verifiable corporate affiliation. If you have any questions about membership or the registration process, please feel free to ask.

AIXPRT Community Preview 2 is almost here!

In last week’s blog, we predicted that the second AIXPRT Community Preview (CP2) would be ready for release later this month. Since then, the development process has accelerated, and we now expect to release CP2 as early as tomorrow, May 10.

Those who have access to the existing AIXPRT Community Preview GitHub repository will be able to access CP2 the same way as before. In addition to making the build available on GitHub, we’ll also post CP2 on an AIXPRT tab in the XPRT Members’ Area (login required). If you don’t have a BenchmarkXPRT Development Community membership, please contact us and we’ll help you register.

Testing with AIXPRT CP2 in Ubuntu will be the same as with the first CP, and none of the CP2 changes will affect results. In Windows, testers will be able to use OpenVINO to target a system’s CPU and GPU, and TensorFlow to target CPUs. We’re still investigating ways to support TensorFlow GPU and TensorFlow-TensorRT testing in Windows.

We’re also continuing to work on the improvements to the AIXPRT results viewer that we mentioned last week. We won’t be able to implement all of the changes by tomorrow, but rather than waiting until we’re finished, we’ll be rolling out improvements as they become ready.

We’ll continue to keep everyone up to date with AIXPRT news here in the blog. If you have any questions or comments, please let us know.

An update on AIXPRT development

It’s been almost two months since the AIXPRT Community Preview went live, and we want to provide folks with a quick update. Community Preview periods for the XPRTs generally last about a month. Because of the complexity of AIXPRT and some of the feedback we’ve received, we plan to release a second AIXPRT Community Preview (CP2) later this month.

One of the biggest additions in CP2 will be the ability to run AIXPRT on Windows. AIXPRT currently requires test systems to run Ubuntu 16.04 LTS. This is fine for testers accustomed to Linux environments, but presents obstacles for those who want to test in a traditional Windows environment. We will not be changing the tests themselves, so this update will not influence existing results from Ubuntu. We plan to make CP2 available for download from the BenchmarkXPRT website for people who don’t wish to deal with GitHub.

Also, after speaking with testers and learning more about the kinds of data points people are looking for in AIXPRT results, we’ve decided to make significant adjustments to the AIXPRT results viewer. To make it easier for visitors to find what they’re looking for, we’ll add filters for key categories such as batch size, toolkit, and latency percentile (e.g., 50th, 90th, 99th), among others. We’ll also allow users to set desired ranges for metrics such as throughput and latency.

Finally, we’re adding a demo mode that displays some images and other information on the screen while a test is running to give users a better idea what is happening. While we haven’t seen results change while running in demo mode, users should not publish demo results or use them for comparison.

We hope to release CP2 in the second half of May and a GA version in mid-June. However, this project has more uncertainties than we usually encounter with the XPRTs, so that timeline could easily change.

We’ll continue to keep everyone up to date with AIXPRT news here in the blog. As always, we appreciate your suggestions. If you have any questions or comments about AIXPRT, please let us know.

All about the AIXPRT Community Preview

Last week, Bill discussed our plans for the AIXPRT Community Preview (CP). I’m happy to report that, despite some last-minute tweaks and testing, we’re close to being on schedule. We expect to take the CP build live in the coming days, and will send a message to community members to let them know when the build is available in the AIXPRT GitHub repository.

As we mentioned last week, the AIXPRT CP build includes support for the Intel OpenVINO, TensorFlow (CPU and GPU), and TensorFlow with NVIDIA TensorRT toolkits to run image-classification workloads with ResNet-50 and SSD-MobileNet v1 networks. The test reports FP32, FP16, and INT8 levels of precision. Although the minimum CPU and GPU requirements vary by toolkit, the test systems must be running Ubuntu 16.04 LTS. You’ll be able to find more detail on those requirements in the installation instructions that we’ll post on AIXPRT.com.

We’re making the AIXPRT CP available to anyone interested in participating, but you must have a GitHub account. To gain access to the CP, please contact us and let us know your GitHub username. Once we receive it, we’ll send you an invitation to join the repository as a collaborator.

We’re allowing folks to quote test results during the CP period, and we’ll publish results from our lab and other members of the community at AIXPRT.com. Because this testing involves so many complex variables, we may contact testers if we see published results that seem to be significantly different than those from comparable systems. During the CP period, On the AIXPRT results page, we’ll provide detailed instructions on how to send in your results for publication on our site. For each set of results we receive , we’ll disclose all of the detailed test, software, and hardware information that the tester provides. In doing so, our goal is to make it possible for others to reproduce the test and confirm that they get similar numbers.

If you make changes to the code during testing, we ask that you email us and describe those changes. We’ll evaluate if those changes should become part of AIXPRT. We also require that users do not publish results from modified versions of the code during the CP period.

We expect the AIXPRT CP period to last about four to six weeks, placing the public release around the end of March or beginning of April. In the meantime, we welcome your thoughts and suggestions about all aspects of the benchmark.

Please let us know if you have any questions. Stay tuned to AIXPRT.com and the blog for more developments, and we look forward to seeing your results!

Principled Technologies and the BenchmarkXPRT Development Community release HDXPRT 4, a benchmark designed to show how well Windows devices handle real-world media tasks

Durham, NC, February 25 — Principled Technologies and the BenchmarkXPRT Development Community have released HDXPRT 4, a free benchmark that gives objective information about how well Windows 10 devices handle common media-creation tasks. HDXPRT 4 uses real commercial applications, like Photoshop and MediaEspresso, to perform tasks based on three everyday scenarios: photo editing, video conversion, and music editing. After the test is finished, the tool provides an overall measure by generating a single performance score. Anyone can go to HDXPRT.com to compare existing performance results on a variety of devices, or to download the app for themselves.

“When we started working on HDXPRT 4, we knew we wanted to create a benchmark that accurately reflects the kind of work average consumers do when creating content on their PCs,” said Bill Catchings, co-founder of Principled Technologies, which administers the BenchmarkXPRT Development Community. “HDXPRT delivers clear results that make sense to the wide audience of buyers shopping for new Windows systems.”

HDXPRT is part of the BenchmarkXPRT suite of performance evaluation tools, which includes WebXPRT, MobileXPRT, TouchXPRT, CrXPRT, and BatteryXPRT. The XPRTs help users get the facts before they buy, use, or evaluate tech products such as computers, tablets, and phones.

HDXPRT 4 is here!

We’re excited to announce that HDXPRT 4 is now available to the public! Just like previous versions of HDXPRT, HDXPRT 4 uses trial versions of commercial applications to complete real-world media tasks. The HDXPRT 4 installation package includes installers for some of those programs, such as Audacity and HandBrake. For other programs, such as Adobe Photoshop Elements and CyberLink Media Espresso, users will need to download the necessary installers prior to testing by using the links and instructions in the HDXPRT 4 User Manual.

In addition to the editing photos, editing music, and converting videos workloads from prior versions of the benchmark, HDXPRT 4 includes two new Photoshop Elements scenarios. The first utilizes an AI tool that corrects closed eyes in photos, and the second creates a single panoramic photo from seven separate photos.

HDXPRT 4 is compatible with systems running Windows 10, and is available for download at HDXPRT.com. The installation package is about 4.8 GB, so the download may take several minutes. The setup process takes about 30 minutes on most computers, and a standard test run takes approximately an hour.

After trying out HDXPRT 4, please submit your scores here and send any comments to BenchmarkXPRTsupport@principledtechnologies.com. To see test results from a variety of systems, go to HDXPRT.com and click View Results, where you’ll find scores from a variety of devices. We look forward to seeing your results!
