Beijing time January 12th morning news, Intel said in the blog, PC installed Spectre/Meltdown patch, the speed will be less than 10%. Why do you say that? Anger evaluated the performance changes of the Windows 10 computers, which were installed in the 6, 7, or 8 generation of Intel CPU.
Intel believes that if the system is equipped with 8 generation CPU (that is, Kaby Lake, Coffee Lake) and SSD, the impact is minimal and decelerate less than 6%. If you install the 7 generation Kaby Lake-H mobile processor, it slows down about 7%. If it's the 6 generation Skylake-S platform, it slows down about 8%.
You may not find that the speed of the computer is slowing down because it is related to the way it is used. According to Intel's statistics, you can feel a slow speed when you browse the web and use the application. If the application application is high in performance requirements, it will feel more obvious.
At the end of last year, Intel acknowledged that the chips were really vulnerable. A few days ago, Intel confirmed that fixing the patch would slow PC, but the wording of Intel changed when it talked about the impact of patches on computer performance. How much is the impact? It may be more accurate to describe it in numbers.
In addition to today's PC test results, Intel will publish preliminary testing data on the server platform in the next few days. At the same time, Intel also stressed that it has not received any news that someone is using Spectre/Meltdown vulnerabilities to steal customer data. Anyway, it is better for users to install patches.
