Intel® Gigabit CT Desktop Adapter
Bringing PCI Express* Gigabit Performance to the Desktop

For PCs with PCI Express* (PCIe*) slots,
the Intel® Gigabit CT Desktop Adapter of-
fers the newest technology for maximiz-
ing system performance and increasing
end-user productivity. Specically, the
Intel Gigabit CT Desktop Adapter uses au-
to-negotiation to ensure the adapter runs
at the highest available network speed
(10, 100, or 1000 Mbps), and maintains full
bandwidth capacity with the dedicated
bandwidth of a PCIe input/output (I/O) bus
to provide connectivity you can count on.
Based on the low-power Intel® 82574L
Gigabit Ethernet Controller, this desktop
adapter offers optimal performance in
a low-cost, low-power, compact prole.
Teaming support and an array of other
advanced features enable customers to
use this adapter as an entry-level server
adapter as well.

Fast servers and server connections are
important for high network performance.
However, server speed cannot overcome
the drag of slow desktop performance.
When a desktop PC initiates a transaction
with the network server, the server quick-
ly performs its portion of the transac-
tion, but must wait for the desktop PC to
complete its part of the transaction. The
slower the PC, the longer the server must
wait for transaction completion before
moving to the next transaction. With PCIe
Gb performance to the desktop, transac-
tions on the PC side complete signicantly
faster, allowing the network to service
more transactions faster.

PCI Express is the third-generation I/O
standard with performance that super-
cedes the previous PCI and PCI-X* slot
standards. The key to PCIe performance is
its higher dedicated I/O bandwidth. Unlike
the PCI bus, which shares its I/O resources
with all devices on the bus, PCIe dedicates
its I/O to a single device. The Intel Gigabit
CT Desktop Adapter allows you to take ad-
vantage of this dedicated I/O by combining
Gigabit Ethernet with PCI Express to pro-
vide high-performance network connec-
tivity for desktops with PCI Express slots.
Make the Intel Gigabit CT Desktop Adapter
your choice for applications utilizing rich
media content such as video streaming,
web applications, music, and gaming.
