Specter bugs are actually two versions, CVE-2017-5715 can be resolved through software updates, CVE-2017-5053 you must be hardware-level repair, seven generations of Core Duo has been completed.
Now Intel has released a patch for the second generation of Specter vulnerabilities to the fourth generation of Core Haswell and the fifth generation of the Broadwell family, emphasizing a stable patch, that is, it should not cause a restart.
Haswell first released in 2013, the following year conducted a speed upgrade, so the product is particularly large.
Broadwell is the product of 2015, but most are mobile platforms, only two on the desktop, so the impact is relatively small.
