Soon, we’ll know the truth

I’m writing this on the morning of one of the most anticipated events in tech, Samsung’s rollout of the new Galaxy S4 phone.  There have been many leaks, and it will be interesting to see how many are true. One feature generating buzz would let you scroll just by moving your eyes. Samsung filed for the patent, but there are conflicting reports about whether eye scrolling made it into the Galaxy S4.

The leaked reports say that the U.S. version of the Galaxy S4 will use Qualcomm Inc.’s quad-core chip, while versions for other markets will use Samsung’s Exynos 5 Octa-core chip. As we continue development of PhoneXPRT, I will be very interested to see how the different processors stack up performance wise.

For browser-level performance, WebXPRT 2013 is available today. If you get a new Galaxy S4, try out WebXPRT 2013 on it.  As it says on the page, your run is confidential. However, anyone who shares a Galaxy S4 score in the next week gets a free t-shirt (until they are gone). You can tag BenchmarkXPRT on a Facebook post, use the hashtag #WebXPRT on Twitter, or email us at

In other news, the HDXPRT 2013 comment period has ended and we’re working on the design document.  We’ll be sharing that with the community next week. If you have comments you haven’t sent in, please do so, and we’ll try to address them in the design document.

No time to rest

Last week was possibly our biggest week ever. We announced PhoneXPRT, a new benchmark for evaluating the performance of smartphones, and released TouchXPRT 2013 and WebXPRT 2013 to the general public.

Since then, there’s been a lot of interest. The numbers keep going up! We’re not just talking about page views – people are downloading TouchXPRT and lots of people are running WebXPRT.

People have also been downloading the TouchXPRT source, which is very exciting. We strongly encourage community members to look at how the benchmark is put together. If you have programming skills and want to submit code, get in touch with us at  We’d love to hear from you!

Oh, and there’s a new video! This one introduces WebXPRT to the public. It gives a good idea of the range of devices WebXPRT will run on.

That’s a lot for one week. We’re not resting on our laurels, though. Obviously, we’re working on PhoneXPRT. However, let’s not forget about HDXPRT. The comment period for HDXPRT 2013 officially closed on March 6 and we are starting to work on the HDXPRT 2013 design document. If you have any feedback you haven’t sent, please do send it on. We’ll do our best to incorporate it into the design document.

What a week!

This has been quite a week for the BenchmarkXPRT family. We kicked off the week by announcing a new benchmark: PhoneXPRT. PhoneXPRT is designed to test small form factor devices, such as smart phones.  PhoneXPRT will initially run on Android. For more information, read the press release at

There was more to come. Today we formally released TouchXPRT 2013 and WebXPRT 2013. The community and the media have been using these as community previews for weeks now. Now that we’ve released the benchmarks, anyone may freely use them.  You can read the press release at

We have also released the TouchXPRT 2013 source to the community. The instructions for building the benchmark are the same as for building the community preview. Remember that community members have access to the source, but it is not available to the general public.

As WebXPRT 2013 moves from being a community preview to a public release, people may have concerns about privacy. While anyone using WebXPRT 2013 agrees to share their results, the database does not store any identifying information.

Remember, the HDXPRT comment period is still open! Please send your comments in. If you’ve not read the RFC yet, you can find it at
