Motorola DROID RAZR HD Full Review

Performance Testing: CPU, Browser And Graphics

In addition to using the Motorola DROID RAZR HD in a variety of everyday usage scenarios, we also conducted some formal performance testing to see how well the handset compares to other smartphones in the same class of devices.
CPU testing
Android CPU testing

In the Linpack test, the Droid RAZR HD put up an impressive score, thrashing flagship phones from six to nine months ago and even besting the HTC One X and Galaxy S III by just a hair, though they share the same dual-core Qualcomm Krait architecture in the Snapdragon S4 SoC.

Graphics testing
Android graphics testing



In our graphics tests with GLBenchmark and An3DBench XL, the RAZR HD proved itself about on par with other high-end Android superphones, but unable to catch the powerful A6-based Apple iPhone 5.  Fillrate for the dual-core Qualcomm Snapdragon S4 SoC with Adreno 225 graphics isn't anything to write home about, though overall geometry and rendering throughput is respectable. However, actual gaming on the RAZR HD was plenty responsive with some of Mot/Verizon's included titles like Real Racing 2.

JavaScript testing
JavaScript Android and iPhone testing

Sunspider measures Javascript performance, which is very common workload for web applications and sites when browsing the Internet.  Only the HTC One X and Galaxy S III phones completed the SunSpider test with quicker times, and even those two just barely beat out the RAZR HD.

Rightware BrowserMark testing
Browser-based testing

Rightware's BrowserMark is a benchmark that provides tests to measure browser performance in the context of JavaScript, HTML5, WebGL, CSS and other standards. This benchmark puts the RAZR HD near the top of our Android heap currently (about on par with the RAZR M, and within the test's margin of error).  However, again the iPhone 5 takes the lead spot in this metric.
