In a recent update, Hardkernel added three new SBCs to their ODROID series the ODROID H4, ODROID H4+, and ODROID H4 Ultra. The ODROID H4 and the H4+ features a 4-core Intel N97 processor, while the flagship H4 Ultra utilizes the 8-core Intel i3 N305 processor.

The N97 is an Intel processor with 4 cores (4C) operating at a clock speed range of 2.0 – 3.6 GHz. It has 6MB of cache memory, a low power consumption of 12W TDP, and integrated Intel UHD Graphics (reaching up to 1.20 GHz) with 24 Execution Units.

In comparison, the Core i3-N305 boasts 8 cores and 8 threads (8C/8T), a clock speed range of 1.8 – 3.8 GHz, 6MB of Smart Cache, slightly higher power consumption at 15W TDP, and Intel UHD Graphics (peaking at 1.25 GHz) with a greater number of Execution Units at 32.

The units have DDR5 SO-DIMM slots supporting up to 4800 MT/s and 48GB capacity. Storage includes eMMC connectors and options for SATA3 ports and an M.2 slot. Networking features two 2.5 GbE LAN ports with Wake-On-LAN. Display support includes triple 4K@60Hz. Audio capabilities include dual 3.5mm jacks and SPDIF out. Connectivity offers USB 3.0, USB 2.0 ports, and a 24-pin expansion header for UART and I2C.
