Thermal Grease; Video Cards - Dell Inspiron 13z Manual

Thermal Grease

Thermal grease, also called thermal gel, thermal compound, and so on, is
used to create a heat inductive layer between a processor and heat sink.
Applying thermal grease between the processor and heat sink increases
the heat transfer from the processor to the heat sink, as the thermal
grease has better conductivity than air.

Video Cards

Video card is a component that sends video signals or information to a
display device such as a monitor or projector.
Video cards can be of two types:
• Integrated video – Often referred to as an on-board video card, it is
a chip that is part of the system board. Integrated video cards do not
have dedicated memory, and share the system memory and processor
to output video. Integrated video cards are suitable for users who do
not require high video performance.
• Discrete video – Discrete video cards are installed separately on
the system board. Discrete video cards have dedicated memory on
the cards and generally provide higher performance than integrated
video cards. These video cards are generally installed in a PCI-E x16
expansion slots on the system board. Legacy connectors for
video cards include PCI and AGP. These cards are best suited for
graphic-intensive applications, playing high-definition video games,
and so on.
NOTE: When a discrete video card is installed on a computer that also
has an integrated video card, the integrated video card is disabled.
Use the system setup program to manually enable the integrated
video card.
• Accelerated Processing Unit (APU) – APUs are formed by etching a
graphics processing unit (GPU), or any other processing system on
the same chip as the CPU. Hence, APUs provide higher data transfer
rates while reducing the power consumption which improves the
performance of the computer when compared to Integrated video.
