Intel releases its post Meltdown and Spectre performance figures

@ 2018/01/11
Impact a little worse than claimed

Chipzilla has come out with some performance impact data on its post patch 6th, 7th and 8th Generation Intel Core processor platforms using Windows 10 and its figures are not exactly good for older PCs.

Intel previously said that we expected its performance impact should not be significant for average computer users, and it thinks the data it is sharing today support that expectation on these platforms.

Intel said: "The performance impact of the mitigation on 8th generation platforms (Kaby Lake, Coffee Lake) with SSDs is small. Across a variety of workloads, including office productivity and media creation as represented in the SYSMark2014SE benchmark, the expected impact is less than six percent. In certain cases, some users may see a more noticeable impact. For instance, users who use web applications that involve complex JavaScript operations may see a somewhat higher impact (up to 10 percent based on our initial measurements). Workloads that are graphics-intensive like gaming or compute-intensive like financial analysis see minimal impact.
