BIOS升级包中并没有此类的描述。

ENHANCEMENTS:
- Updates the NVIDIA N17P-Q3 Graphics VBIOS to version 84.06.7A.00.14.
- Provides the updated Intel i219 UEFI drivers.
- Provides the updated Realtek UEFI drivers.
- Provides improved security on systems using the Skylake processor.
- Provides Battery Safety Mode for systems subject to a Battery Safety Recall.
- Provides improved security of UEFI code and variables in an Intel system. HP
strongly recommends transitioning promptly to this updated BIOS version which
supersedes all previous releases.

NOTE: Due to the security changes in this release, attempts to install older
BIOS versions require the user to be physically present to accept the older
version.

FIXES:
- Fixes an issue where a system connected to a Targus dock does not power on
properly and stops functioning (hangs) when a Dell keyboard is connected to the
dock.
- Fixes an issue on a system with an Intel processor where the CPU usage is
unexpectedly high when Wake On LAN is used.
- Fixes an issue where an integrated microphone that has been disabled in the
F10 BIOS menu continues to function on the system.
- Fixes an issue where an internal speakers that have been disabled in the F10
BIOS menu continue to function on the system.
- Fixes an issue where the headphone output that has been disabled in the F10
BIOS menu continues to function on the system.
- Fixes an issue where audio input/output cannot be changed to an external
device connected to the system.
- Fixes an issue on a system that has an NVIDIA N17P-Q3 graphics installed with
Legacy support disabled where the system displays a blank screen during POST
(power-on self test).

这一项不是针对intel熔断、幽灵漏洞的？

是。

我记得明明我打了一行字上去，贴出来就没了，我的意思是说BIOS中没有关于更新了BIOS之后Intel CPU或芯片组性能有下降多少的描述，在官网的说明上也没有关于此信息的描述。

性能下降一定会有，但是具体多少就不一定了，毕竟每个人用的软件不一样，没办法具体测试。
