Performance
The Z1 G2 Thunderbolt module implements Thunderbolt 2 technology. Thunderbolt 2 technology provides 20Gbps
of combined bandwidth in each direction for both inbound and outbound PCI Express and DisplayPort protocols. The
20Gbps bandwidth is capable of transporting DisplayPort 1.2 4k video streams as a single stream or four 1920x1080 HD
streams via the MST protocol. 4k video capture input can be achieved simultaneously with 4k DisplayPort output by using
Thunderbolt's integrated PCI Express capability.
Thunderbolt module paired with Intel® HD Graphics
Intel HD Graphics
The new integrated Intel HD Graphics 4600 on Intel Core™ i5 CPU2 and Intel HD Graphics 4400 on Intel Core i3 CPU2
graphics engine provide professional entry graphics performance. Available on Intel Xeon® E3-12x5 v3 processor
2
models, it comes certified for selected popular workstation applications. The Intel HD Graphics P4600 graphics core
integrated in Intel Xeon processors has 2 graphics cores and 20 Execution Units and offers higher performance than
the previous generation Intel HD Graphics P4000, which has 16 Execution Units. The Intel HD Graphics P4600 supports
Microsoft DirectX11.1, OpenCL 1.2 and OpenGL 4.0. It supports expanded media acceleration features like full hardware
decode and encode acceleration as well as advanced video processing features.
Thunderbolt 2 features when combined with Intel HD Graphics P4600
When pairing the Z1 G2 Thunderbolt module with Intel HD Graphics one Thunderbolt 2 port is available.
Multiple displays support
Intel HD Graphics support 3 independent and simultaneous displays and support Clone, Extended and Collage modes for
the displays. In the case of 3 simultaneous displays, two High Definition Audio streams over the digital display interfaces
are supported. The HP Z1 G2 routes the 3 ports from the Intel HD Graphics as follows:
• DisplayPort 1.1a to the internal display at 2560 x 1440 @ 60 Hz maximum resolution
• DisplayPort 1.1a to the external DisplayPort connector on the rear I/O at 2560 x 1600 @ 60 Hz maximum resolution
• DisplayPort 1.2 to the optional Thunderbolt 2 module at 4096 x 2160 at 24 Hz or 3840 x 2160 @ 60 Hz maximum
resolution to a single display.
Thunderbolt module paired with NVIDIA professional graphics
Graphics
The Z1 G2 supports discrete NVIDIA professional graphics via an MXM 3.1 slot with a PCIe3 x16 link. The following
NVIDIA professional graphics cards are supported: K610M, K2100M, K3100M and K4100M.
The NVIDIA graphics can drive the internal LCD or the internal LCD plus external monitors. The discrete NVIDIA graphics
option always overrides the Intel integrated processor graphics. If you want to use the Intel integrated processor
graphics, the discrete NVIDIA graphics card must be removed from the system.
Thunderbolt 2 features when combined with NVIDIA professional graphics
When pairing the Z1 G2 Thunderbolt module with NVIDIA professional graphics, two Thunderbolt 2 ports are available.
Multiple displays support
NVIDIA professional graphics cards drive up to 4 independent and simultaneous displays and support Clone, Extended or
Mosaic modes for the displays. The Z1 G2 routes the 4 outputs of the NVIDIA card as follows:
• DisplayPort 1.1a to the internal display at 2560 x 1440 @ 60 Hz maximum resolution
• DisplayPort 1.1a to the external DisplayPort connector on the rear I/O at 2560 x 1600 @ 60 Hz maximum resolution
• DisplayPort 1.2 to the optional Thunderbolt 2 module port 1 at 4096 x 2160 maximum resolution to a single display
• DisplayPort 1.2 to the optional Thunderbolt 2 module port 2 at 4096 x 2160 maximum resolution to a single display
