Patched Laptops: Testing Meltdown & Spectre Patches on Ultraportable-Class Hardware

[Julio Franco]

You've probably seen our coverage and tests over the past few weeks on the Meltdown and Spectre vulnerabilities, or more specifically the performance drops you can expect from the patches that address these issues. We've already covered what you can expect on modern desktop systems, however today we'll be diving into the mobile side of things to see how Meltdown and Spectre patches affect ultraportable laptops.

You mean the PCMark 8 one?

PCMark and 3DMark were wrong (higher is better is correct), now fixed, thank you.
