This avoids flushes on VM transitions to give a lower-cost VM transition time
and an overall reduction in virtualization overhead.
Guest Preemption Timer
Mechanism for a VMM to preempt the execution of a guest OS after an amount
of time specified by the VMM. The VMM sets a timer value before entering a
guest
guest
The feature aids VMM developers in flexibility and Quality of Service (QoS)
guarantees
Descriptor-Table Exiting
Descriptor-table exiting allows a VMM to protect a guest OS from internal
(malicious software based) attack by preventing relocation of key system data
structures like IDT (interrupt descriptor table), GDT (global descriptor table),
structures like IDT (interrupt descriptor table), GDT (global descriptor table),
LDT (local descriptor table), and TSS (task segment selector).
A VMM using this feature can intercept (by a VM exit) attempts to relocate
these data structures and prevent them from being tampered by malicious
software.

Intel Graphics Dynamic Frequency
Graphics render frequency are selected by the Intel graphics driver dynamically based
on graphics workload demand as permitted by Intel Turbo Boost Technology Driver. The
processor core die and the integrated graphics and memory controller core die have an
individual TDP limit. If one component is not consuming enough thermal power to
reach its TDP, the other component can increase its TDP limit and take advantage of the
unused thermal power headroom. For the integrated graphics, this could mean an
increase in the render core frequency (above its rated frequency) and increased
graphics performance.

Note:
Please note that processor Turbo is not supported on Celeron processor skus.
Processor Utilization of Intel Graphics Dynamic Frequency require the following

Enabling Intel Turbo Boost Technology and Intel Graphics Dynamic Frequency will
maximize the performance of the GPU within its specified power levels. Compared with
previous generation products, Intel Turbo Boost Technology and Intel Graphics
Dynamic Frequency will increase the ratio of application power to TDP. Thus, thermal
solutions and platform cooling that are designed to less than thermal design guidance
might experience thermal and performance issues since more applications will tend to
run at the maximum power limit for significant periods of time. For more details, refer
