Agenda
• Wicked Fast Storage : Intel® Optane™ SSDs
Based on 3D XPoint™ Technology
• Client/Workstation Impact (and why)
• Data Center Impact (and why)
• And Beyond : Intel® DIMMs Based on 3D
XPoint™ Technology

3D XPoint™ Technology
Cross Point
Structure
Selectors allow dense
packing and individual
access to bits
Scalable
Memory layers
can be stacked in
a 3D manner

Breakthrough
Material Advances
Compatible switch and
memory cell materials
High Performance
Cell and array architecture that
can switch states 1000x¹ faster
than NAND
¹Technology claims are based on comparisons of latency, density and write cycling metrics amongst memory technologies recorded on published specifications of
in-market memory products against internal Intel specifications.

Historically Significant Storage Advances
“There is an old
network saying:
Bandwidth
problems can be
cured with money.
Latency problems
are harder because
the speed of light is
fixed—you can’t
bribe God.”
