Intel has released a PR statement saying they have released updates for Meltdown and Spectre that make systems immune from both exploits. Supposedly they are doing this with firmware and software patches. Also, they will have updates issued for 90% of the processors introduced over the last 5 years by the end of next week. They appear to be confident that performance impact will be able to be worked around with additional software updates. However, I'll take all of this with a grain of salt until independent sources confirm these claims. Intel continues to believe that the performance impact of these updates is highly workload-dependent and, for the average computer user, should not be significant and will be mitigated over time. While on some discrete workloads the performance impact from the software updates may initially be higher, additional post-deployment identification, testing and improvement of the software updates should mitigate that impact.
