Thunderbolt

2 technology overview

The Thunderbolt 2 module provides transformational high-speed, dual protocol

I/O that enables unmatched performance over current I/O technologies with

20Gbps bi-directional transfer speed. It provides exibility and simplicity by

supporting both data (PCIe) and video (DisplayPort) on a single connection that

can daisy-chain up to six devices.

2 technology overview

Thunderbolt 2 technology key features

The Z1 G2 provides Thunderbolt 2 technology via an optional module that replaces the ODD in the side I/O bay.

This module uses the Intel® DSL5520 Thunderbolt 2 controller and provides two Thunderbolt 2 ports when used

with NVIDIA professional graphics. When pairing the Z1 G2 Thunderbolt module with Intel HD Graphics, one

Thunderbolt 2 port is available.

Thunderbolt technology dramatically increases the data transfer rate enabling faster backup, editing and le sharing,

signicantly reducing the time to complete key tasks. Thunderbolt technology was specically designed with inherently

low latency and highly accurate time synchronization capabilities. These features enable extremely accurate audio and

video creation, playback and editing that no other standard interconnect technology can match.

Each Thunderbolt 2 port provides:

• 20Gbps bi-directional data transfer

• Data & Video on a single cable with dual-protocol PCI Express and DisplayPort

• Daisy-chaining of up to 6 devices

• Uses native PCIe and DisplayPort protocol software drivers

• Power over cable for bus-powered devices

• Compatible with existing DisplayPort devices

• DisplayPort 1.2 capability with Multi Stream Transport (MST) support that enables the transport of multiple

A/V streams over a single connector

• Maximum 4096 x 2160 resolution at 60 Hz (8-bit display) or at 30 Hz (10-bit display) to a single display

• Maximum 3840 x 2160 resolution at 60 Hz (8-bit display) or at 30 Hz (10-bit display) across 4 displays

— Each of the 4 displays can support a 1920 x 1080 resolution

• 4K video le transfer and display simultaneously

• Full backward compatibility with Thunderbolt devices

HP recommends Windows.
