Today, Navin Shenoy, Intel's executive vice president and general manager of datacenter business unit, released a second performance test article aimed at the client after the desktop user has patched patches for 'Specter' and 'Meltdown' vulnerabilities.
The performance impact is not significant for most average PC users, and the data we publish today support these notions.
Intel said defensive measures have had little impact on performance for Kaby Lake, Coffee Lake equipped with SSDs and eight generations of cores.
In a variety of workloads, including the SYSMark2014SE benchmarks represented in office software and media production, Estimated impact of less than 6%.
In certain situations, users may be more affected. For example, Users using web applications that involve complex JavaScript operations may be more affected (our initial tests show up to 10%). Computing-intensive workloads such as graphics-intensive workloads or financial analysis are the least affected.
Official tests showed that the seventh-generation Kaby Lake-H high-performance mobile platform (laptop scale) was affected by the eighth-generation platform (about 7% in the SYSMark2014SE benchmark).
For the sixth generation Skylake-S platform, tests show that performance is slightly more affected , But with the eighth generation, the seventh generation platform is still generally affected by the impact (SYSMark2014SE benchmark test of about 8%We also used Windows 7 to do benchmarks on the same platform.
As a result, the impact observed by the test was small (about 6% on the SYSMark2014SE benchmark), even lower than for systems with hard disks.
Intel also said it plans to provide representative data for the mobile and desktop platforms introduced in the past five years in the coming week.
The following table summarizes the related benchmarks, platforms and test results -
