Cmini High Speed GPU Expansion Dock JHL7440 PD85W+15W Graphics Card Expansion Dock with 60cm Thunderbolt4 Cable

Description:
- The new Thunderbolt controller provides a bidirectional transmission rate of up to 24Gbps through 4XPCle Gen3 in PCIe tunnel transmission mode. Compared with the previous generation Thunderbolt controller, there is a significant improvement in transmission rate and delay, with an amplitude of up to 50%. In some game scenarios, 1% low frames increase by more than 50%. A 99% average frame rate can increase by 20%.

Key Features:
- JHL7440 high performance main control.
- Double thunderbolt daisy chain.
- Upgraded 85W+15W double reverse charging.
- DP1.4 + USB3.2Gen2 expansion output.
- Compatible with redundant design and continuously connected.

Characteristics:
- It integrates 5 high-speed interfaces on one board. It has super strong anti-interference performance when transmitting high-speed data simultaneously, ensuring no speed drop and continuous connection.
  PCle Gen3 x 4, 24Gb/s
  10Gb/s, USB3.2Gen2
  2 x 40Gb/s, Thunderbolt
  4 x HBR3 link, DisplayPort1.4
- Multi device compatibility: After targeted optimization, it has solved the common code "12" and "43" errors in the JHL7440 series in graphics card dock application scenarios, and its compatibility is far superior to that of general graphics card docks.
- It adopts an 85W reverse charging scheme compatible with PD3.0 protocol, which can continuously maintain an output power higher than 85W and meet 99% of the device's power supply needs.
- It supports soft boot function. It can automatically start and recognize with upstream equipment, and the device will automatically start at the moment of thunderbolt connection. (The power switch needs to be turned on and the power cords must be properly connected.)
- Whether it is an external gaming monitor or a large screen TV, it can be provided using the full speed DisplayPort1.4 interface 4K at 144Hz /5K60Hz driving capability.
- In professional fields such as video editing, 3D modeling and rendering, and AI model training, external use of Cmini can provide almost lossless user experience.
- This thunderbolt graphics card docking station is perfectly compatible with various network cards, sound cards, video acquisition cards, RAID array cards, etc. based on PCIE transmission protocol, and is more than twice as fast in data exchange compared to devices based on USB/SATA protocol.
