With the new improved Intel patches to protect against Spectre and Meltdown, The Tech Report made the effort to revisit the performance impact you can expect on a system with a Core i7-7700HQ and a Samsung PM961 512 GB NVMe SSD.  Javascript tests show a noticeable drop in performance and while PCMark Essentials total score showed a dip in performance the gaming specific tests did not.  It will be interesting to see if this levels the playing field between Ryzen and Skylake, as the performance delta is already very small.  Check out the full results here.

"Intel recently released stable microcode updates to mitigate the Spectre vulnerability on Skylake and newer CPUs. We ran back-to-back tests with and without the patch on one of our Kaby Lake systems to see just how much performance suffers in exchange for safety."
