The ODROID H-series is growing with three brand new models.

Again, the new generation is more powerful and offers higher performance. 
It also delivers key new IO that will please many users.

Introducing the ODROID-H4, H4+ and H4 Ultra

ODROID is introducing the ODROID-H4, H4+ and H4 Ultra, which is equipped with higher performance and richer interfaces (ODROID H4 Series requires a 92x92x15mm Fan for all cases, case Type 4 uses 92x92x25mm but is included with the Type 4 Case.).

KEY FEATURES

• Faster CPU architecture Alder Lake N vs. Jasper Lake. Plus AVX2 extensions.
• Faster DRAM interface DDR5 4800 MT/s vs. DDR4 2933 MT/s.
• Higher base and boost CPU frequencies and more powerful iGPU.
• The increase from 2 to 4 SATA ports allows connection to a greater number of storage devices, ODROID-H4+ and ODROID H4 Ultra only.
• An additional DisplayPort added allows the simultaneous use of up to 3 monitors.
• Low cost ODROID H4 for compute and graphics applications (e.g signage, robot, factory automation,..)
• Flagship H4 Ultra doubling the number of CPU cores, from 4 to 8 cores.
• Dual BIOS: If the BIOS is corrupted due to a power outage during update, etc., you can boot into the backup BIOS and recover by moving the jumper next to the DC jack. This feature is only available on ODROID-H4+ and ODROID H4-Ultra.
• The new H4 cases format has been improved so that a cooling fan can be mounted inside the case.
• A Mini-ITX kit for seamless integration with generic ITX PC cases.

NOTES

• The idle power of the H4+ and H4 Ultra models is almost identical, well below the margin of error.
• Even when set to Unlimited Performance Mode (PL4=0), the power difference in idle state is negligible.
• If you change the PCIe ASPM option to Auto, idle power can be reduced by about 1~2 Watt even in the Desktop GUI environment.
• The difference in idle power between the H4 and H4+ models is approximately 0.7 to 1.5 Watt due to the external PCIe-to-SATA controller IC and the power circuitry for SATA devices.
• Only one Ethernet cable is connected.
• In this test, Ubuntu Desktop OS was used, and we think that power consumption could have been slightly reduced if Ubuntu Server OS had been used.
