A clarification from Brett Howse

on February 18, 2016

A couple of weeks ago, I described a conversation I had with Brett Howse of AnandTech. Brett was kind enough to send a clarification of some of his remarks, which he gave us permission to share with you.

“We are at a point in time where the technology that’s been called mobile since its inception is now at a point where it makes sense to compare it to the PC. However we struggle with the comparisons because the tools used to do the testing do not always perform the same workloads. This can be a major issue when a company uses a mobile workload, and a desktop workload, but then puts the resulting scores side by side, which can lead to misinformed conclusions. This is not only a CPU issue either, since on the graphics side we have OpenGL well established, along with DirectX, in the PC space, but our mobile workloads tend to rely on OpenGL ES, with less precision asked of the GPU, and GPUs designed around this. Getting two devices to run the same work is a major challenge, but one that has people asking what the results would be.”

I really appreciate Brett taking the time to respond. What are your thoughts in these issues? Please let us know!

TouchXPRT 2016 is here!

By Eric Hale

on February 15, 2016

Today, we released TouchXPRT 2016, the latest version of our tool for evaluating the performance of Windows devices. The BenchmarkXPRT Development Community has been using a community preview for several weeks, but now anyone can run TouchXPRT 2016 and publish their results.

TouchXPRT 2016 is compatible with systems running Windows 10 and Windows 10 Mobile. The new release includes the same performance workloads as TouchXPRT 2014, but with updated content and in the form of a Universal Windows app.

TouchXPRT 2016 is available at TouchXPRT.com and in the Windows App store.

After trying TouchXPRT 2016, please submit your scores and send any comments to BenchmarkXPRTsupport@principledtechnologies.com. We’re eager to find out how you’ll use this tool!

Comparing apples and oranges?

By Eric Hale

on February 4, 2016

My first day at CES, I had breakfast with Brett Howse from AnandTech. It was a great opportunity to get the perspective of a savvy tech journalist and frequent user of the XPRTs.

During our conversation, Brett raised concerns about comparing mobile devices to PCs. As mobile devices get more powerful, the performance and capability gaps between them and PCs are narrowing. That makes it more common to compare upper-end mobile devices to PCs.

People have long used different versions of benchmarks when comparing these two classes of devices. For example, the images for benchmarking a phone might be smaller than those for benchmarking a PC. Also, because of processor differences, the benchmarks might be built differently, say a 16- or 32-bit executable for a mobile device, and a 64-bit version for a PC. That was fine when no one was comparing the devices directly, but can be a problem now.

This issue is more complicated than it sounds. For those cases where a benchmark uses a dumbed-down version of the workload for mobile devices, comparing the results is clearly not valid. However, let’s assume that the workload stays the same, and that you run a 32-bit benchmark on a tablet, and a 64-bit version on a PC. Is the comparison valid? It may be, if you are talking about the day-to-day performance a user is likely to encounter. However, it may not be valid if you are making statement about the potential performance of the device itself.

Brett would like the benchmarking community to take charge of this issue and provide guidance about how to compare mobile devices and PCs. What are your thoughts?

The XPRT Women Code-a-Thon

By Eric Hale

on January 28, 2016

As Justin explained last week, we’ve resolved the issue we found with the TouchXPRT CP. I’m happy to say that the testing went well and that we released CP3 this week.

It’s been only three weeks since we announced the XPRT Weekly Tech Spotlight, and we already have another big announcement! Principled Technologies has joined with ChickTech Seattle to host the first ever XPRT Women Code-a-Thon! In this two-day event, participants will compete to create the best new candidate workload for WebXPRT or MobileXPRT. The workloads can’t duplicate existing workloads, so we are looking forward to seeing the new ideas.

Judges will study all the workloads and award prizes to the top three: $2,500 for first place, $1,500 for second place, and $1,000 for third place. Anyone interested can register here.

PT and the BenchmarkXPRT Development Community are committed to promoting the advancement of women in STEM, but we also win by doing good. As with the NCSU senior project, the BenchmarkXPRT Development Community will get some fresh perspectives and some new experimental test tools. Everyone wins!

So much has happened in 2016 and January isn’t even over yet. The year is off to a great start!

TouchXPRT 2016 Community Preview 3 is available

By Eric Hale

on January 28, 2016

Today we are releasing TouchXPRT 2016 Community Preview 3 (CP 3). As we discussed in the blog, CP 3 resolves an issue reported on some systems, where the Create Slideshow test would take longer than expected to complete due to the output video not rendering correctly.

As with all community previews, TouchXPRT 2016 CP 3 is available only to community members. Members may download the preview from the TouchXPRT tab in the Members’ Area.

For more details about TouchXPRT 2016, please consult the release notes for further details (login required).

After you try out CP 3, please send us your comments. Either post them to the forum or mail them to BenchmarkXPRTsupport@principledtechnologies.com. If you send us information that’s relevant to the entire community, we may post an anonymous version of your comments to the forum.

Thanks for your participation!

In the spotlight

By Eric Hale

on January 14, 2016

I’m happy to be back in North Carolina, but I had a really great time at CES. I talked to over a dozen companies about the XPRTs and the XPRT Weekly Tech Spotlight, and had some good conversations. Hopefully, some of these companies’ devices will be among the first ones we showcase when the XPRT Weekly Tech Spotlight goes live next month.

Of course, I saw some really great tech at CES! Amazing TVs and cars, magic mirrors, all kinds of drones, and the list goes on. Before the show, the Internet of Things was predicted to be big this year, and boy, was it! Smart refrigerators, door locks, and thermostats were just the beginning. Some of my favorite examples were the chopsticks and footbath—both Bluetooth enabled—and “the world’s first remote controlled game shoe.”

Clearly IoT is the Wild West of technology right now. We’re had some conversations about how the XPRTs might be able to help consumers navigate the chaos. However, with a class of products this diverse, there are a lot of issues to consider. If you have any thoughts about this, let us know!
