Looking for performance clues

We’ve written before about how the operating system and other software can influence test scores and even battery life. Benchmarks like the XPRTs provide overall results, but teasing out which factors affect those results may require some detective work. The key is to collect individual data points as evidence to what may be causing performance [...]

Best practices

Recently, a tester wrote in and asked for help determining why they were seeing different WebXPRT scores on two tablets with the same hardware configuration. The scores differed by approximately 7.5 percent. This can happen for many reasons, including different software stacks, but score variability can also result from different testing behavior and environments. While [...]

CES 2017

I’ve attended many tech shows over the years, but this year’s CES has more energy than any I’ve attended in a long time. Part of the energy is the breadth of products. There are amazingly slim TVs that make my TV at home, which I thought was slim, look fat. And, there are beautiful 8K [...]

Tracking device evolution with WebXPRT ’15, part 2

Last week, we used the Apple iPhone as a test case to show how hardware advances are often reflected in benchmark scores over time. When we compared WebXPRT 2015 scores for various iPhone models, we saw a clear trend of progressively higher scores as we moved from phones with an A7 chip to phones with [...]

An anniversary update

The Windows 10 Anniversary Update release is scheduled for August 2, and we’ve been running the XPRTs on the Windows Insider preview builds. While we can’t publish performance data from developer builds, we’re happy to say that WebXPRT and TouchXPRT run well on the Anniversary Update. The story for HDXPRT 2014 is more complicated. Back [...]

Golden tickets go global

There are seven large halls of booths with phones, tablets, accessories, and gadgets of every sort. I have felt Fujitsu’s haptic technology on a tablet, seen phones [...]
