Hardkernel ODROID-C5 is a lower-cost upgrade to the ODROID-C4 SBC with a faster and more efficient Amlogic S905X5M quad-core Cortex-A55 SoC clocked at 2.5 GHz, 4GB DDR4 RAM, and almost the same features as the previous generation Amlogic S905X3 single board computer. Our Amlogic S905X4 vs S905X5M comparison also mentions that the S905X5M implemented HDMI 2.1 features like QMS, VRR, QFT, and SBTM, but Hardkernel does not mention anything about that. However, there’s one downside since the Amlogic S905X5M lacks the PCIe/USB 3.0 found in the S905X3, so the new SBC only features USB 2.0 ports, while the ODROID-C4 has four USB 3.0 ports. If it does not matter for your use case, then the ODROID-C5 is better and cheaper in every way.
