Hardkernel ODROID-XU4 (Single-Board Computer/Samsung Exynos 5422/Octa-Core big.LITTLE/2GB LPDDR3) Review
The ODROID-XU4 has been a fixture of the SBC hobbyist scene since 2015, built around a Samsung Exynos big.LITTLE octa-core design that was notably powerful for its era and remains adequate for many Linux projects today.
Samsung's Exynos 5422 pairs four Cortex-A15 performance cores with four Cortex-A7 efficiency cores, an architecture approach that predates similar big.LITTLE designs becoming standard across the SBC market.

A Decade of Community Support
The XU4's long market life has produced an unusually deep well of community documentation, cases, and compatible accessories, a genuine advantage for buyers who value proven, well-documented hardware over the newest specs.
Comparison to Alternatives
Against the Hardkernel ODROID-C4 already on this site, the XU4 offers more raw CPU performance thanks to its octa-core big.LITTLE design, at a higher price and older manufacturing process. Against the Hardkernel ODROID-N2+ already on this site, the XU4 is the older, though still capable, sibling in Hardkernel's lineup.
