Phone, Laptop & PC Benchmark – Free CPU Test | DeadTier

Is your phone as good as they say? DeadTier is a free performance test and CPU benchmark that runs in the browser on any phone, tablet, laptop or desktop. Press Run, and in about a minute you'll have a score out of 100, a tier for its type - is this actually a good phone, or a good laptop? - and how smooth it really is when pushed hard. Nothing to install, and every number is measured on the device running it.

Running the test needs JavaScript, because the test is code that runs on your device. The written pages do not:
