I just bought the Dell laptop because I needed a physical machine to test the AVX512 workloads that I created.

For those who care, the performance uplift over AVX2 was largely in line with expectations - 2-2.5X faster.

The 2.5X uplift was due to fact that I leveraged some of the 8 opmask registers to reduce the number of necessary AVX512 instructions in the loop.

There is one peculiar thing about this laptop that I hope someone could help me understand.

When you setup (or modify) a Windows 10 power plan, you are presented with a list of parameters to tweak in the advanced settings dialog.

In this laptop, many of these options are missing:

USB settings
Intel graphics settings
PCI express
Processor power management
Multimedia settings

Perhaps I missed a few.

Why is that?

Also, when I tried to enable Ultimate Performance mode, it failed (it worked on my Kaby Lake Windows 10 laptop at work - that laptop has the missing options listed above).

I obviously want to maximize the performance of this laptop since I am doing performance testing but it feels like I am missing something that is preventing me from extracting the maximum possible performance from the hardware.
