ODROID H4 Plus
Reduced power consumption and higher performance
The ODROID H4 series enhances its versatility by introducing the budget-friendly H4 with simplified hardware on one end of the spectrum, and the high-performance 8-core H4 Ultra flagship on the other end, complementing the H4+.
Comparing H4, H4+, and H4 Ultra to H3+
To assess the performance of the H4 series and its variants against their predecessor, we've chosen to compare them specifically with the H3+ and H3+ UP, which were the fastest in the previous H-series lineup.
For a reminder of how the H3 and H3+ stack up against the H2+, you can check out the comparison here:

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.
Specifications and Comparisons:
Note: While the Intel ARK pages specify the Alder Lake N max. memory to be 16GB, we validated that 32 and 48 GB DDR5 SO-DIMMs 4800 or 5600 MT/s work as well. The 5600 MT/s will run at 4800 MT/s. The Intel specifications for the H2 and H3 processors were
limited as well, but many users were able to (respectfully) pump up the max. memory to 32 and 64 GB.
