Tracking device evolution with WebXPRT ‘15

on October 20, 2016

The XPRT Spotlight on the Apple iPhone 7 Plus gives us a great opportunity to look at the progression of WebXPRT 2015 scores for the iPhone line and see how hardware and software advances are often reflected in benchmark scores over time. This week, we’ll see how the evolution of Apple’s mobile CPU architecture has boosted web-browsing performance. In a future post, we’ll see the impact of iOS development.

As we’ve discussed in the past, multiple factors can influence benchmark results. While we’re currently using the iPhone as a test case, the same principles apply to all types of devices. We should also note that WebXPRT is an excellent gauge of expected web-browsing performance during real-world tasks, which is different than pure CPU performance in isolation.

When looking at WebXPRT ’15 scores in our database, we see that iPhone web-browsing performance has more than doubled in the last three years. In 2013, an iPhone 5s with an Apple A7 chip earned an overall WebXPRT ’15 score of 100. Today, a new iPhone 7 Plus with an A10 Fusion chip reports a score somewhere close to 210. The chart below shows the WebXPRT ’15 scores for a range of iPhones, with each iPhone’s CPU noted in parentheses.

Moving forward from the A7 chip in the iPhone 5s to the A8 chip in the iPhone 6 and the A9 chip in the iPhone 6s and SE, we see consistent score increases. The biggest jump, at over 48%, appears in the transition from the A8 to the A9 chip, implying that folks upgrading from an iPhone 6 or 6 Plus to anything newer would notice a huge difference in web performance.

In general, folks upgrading from an A9-based phone (6S, 6S Plus, or SE) to an A10-based phone (7 and 7 Plus) could expect an increase in web performance of over 6.5%.

The scores we list represent the median of a range of scores for each device in our database. These scores come from our own testing, as well as from device reviews from media outlets such as AnandTech, Notebookcheck, and Tom’s Hardware. It’s worth noting that the highest A9 score in our database (AnandTech’s iPhone SE score of 205) overlaps with the lowest A10 Fusion score (Tom’s Hardware of Germany’s iPhone 7 score of 203), so while the improvement in median scores is clear, performance will vary according to individual phones and other factors.

Soon, we’ll revisit our iPhone test case to see how software updates can boost device performance without any changes in hardware. For more details on the newest iPhones, visit the Spotlight comparison page to see how iPhone 7 and 7 Plus specs and WebXPRT scores stack up.

Taking a detour

By Eric Hale

on October 13, 2016

Back in April, Bill announced that we would be starting development of a cross-platform benchmark. This announcement generated a lot of interest and we got lots of good feedback and ideas.

We knew from the start that getting a cross-platform benchmark right would be hard. However, it proved to be even trickier than we thought. As I explained before, benchmarks not only have to run well, but the results must be fair to all platforms involved. Achieving both of these requirements has been a challenge.

At the same time we’ve been devoting a great deal of effort and resources to the cross-platform benchmark, some increasingly popular new use cases have been receiving less attention than they deserve. We’ve decided that the cross-platform benchmark is not the best use of the Community’s resources, and are going to put it on the shelf for a while. This will free up the resources to let us really dig into some newer technologies.

Thanks again to everyone who responded.

An exciting milestone for WebXPRT!

By Justin Greene

on October 5, 2016

If you’re familiar with the run counter on WebXPRT.com, you may have noticed that WebXPRT recently passed a pretty significant milestone. Since we released WebXPRT 2013, users running WebXPRT 2013 and 2015 have successfully completed over 100,000 runs!

We’re thrilled about WebXPRT’s ongoing popularity, and we think that it’s due to the benchmark’s unique combination of characteristics: it’s easy to run, it runs quickly and on a wide variety of platforms, and it evaluates device performance using real-world tasks. Manufacturers, developers, consumers, and media outlets in more than 358 cities, from Aberdeen to Zevenaar, and 57 countries, from Argentina to Vietnam, have used WebXPRT’s easy-to-understand results to compare how well devices handle everyday tasks. WebXPRT has definitely earned its reputation as a “go-to” benchmark.

If you haven’t run WebXPRT yet, give it a try. The test is free and runs in almost any browser.

We’re grateful for everyone who’s helped us reach this milestone. Here’s to another 100,000 runs!

Rebalancing our portfolio

By Bill Catchings

on September 29, 2016

We’ve written recently about the many new ways people are using their devices, the growing breadth of types of devices, and how application environments also are changing. We’ve been thinking a lot about the ways benchmarks need to adapt and what new tests we should be developing.

As part of this process, we’re reviewing the XPRT portfolio. An example we wrote about recently was Google’s statement that they are bringing Android apps to Chrome OS and moving away from Chrome apps. Assuming the plan comes to fruition, it has big implications for CrXPRT, and possibly for WebXPRT as well. Another example is that once upon a time, HDXPRT included video playback tests. The increasing importance of 4K video might mean we should bring them back.

As always, we’re interested in your thoughts. Which tests do you see as the most useful going forward? Which ones do you think might be past their prime? What new areas do you like to see us start to address? Let us know!

Over the coming weeks, we’ll share our conclusions based on these market forces and your feedback. We’re excited about the possibilities and hope you are as well.

Doing things a little differently

By Eric Hale

on September 8, 2016

I enjoyed watching the Apple Event live yesterday. There were some very impressive announcements. (And a few which were not so impressive – the Breathe app would get on my nerves really fast!)

One thing that I was very impressed by was the ability of the iPhone 7 Plus camera to create depth-of-field effects. Some of the photos demonstrated how the phone used machine learning to identify people in the shot and keep them in focus while blurring the background, creating a shallow depth of field. This causes the subjects in a photo to really stand out. The way we take photos is not the only thing that’s changing. There was a mention of machine learning being part of Apple’s QuickType keyboard, to help with “contextual prediction.”

This is only one product announcement, but it’s a reminder that we need to be constantly examining every part of the XPRTs. Recently, we talked a bit about how people will be using their devices in new ways in the coming months, and we need to be developing tests for these new applications. However, we must also stay focused on keeping existing tests fresh. People will keep taking photos, but today’s photo editing tests may not be relevant a year or two from now.

Were there any announcements yesterday that got you excited? Let us know!

A Chrome-plated example

By Eric Hale

on September 1, 2016

A couple of weeks ago, we talked about how benchmarks have to evolve to keep up with the changing ways people use their devices. One area where we are expecting a lot of change in the next few months is Chromebooks.

These web-based devices have become very popular, even outselling Macs for the first time in Q1 of this year. Chromebooks run Google Apps and a variety of third-party Chrome apps that also run on Windows, Mac, and Linux systems.

Back in May, Google announced that Android apps would be coming to Chromebooks. This exciting development will bring a lot more applications to the platform. Now, Google has announced that they will be “moving away” from the Chrome apps platform and will be phasing out Chrome app support on other platforms within the next two years.

Clearly, the uses of Chromebooks are likely to change a lot in coming months. Interestingly, part of the rationale Google gives for this decision is the development of powerful new Web APIs, which will have implications for WebXPRT as well.

As we’ve said before, we’ll be watching and adapting as the applications change.
