ARM is the architecture behind Raspberry Pi and most single-board computers covered on this site. These posts deal with Java on ARM: JDK builds, performance quirks, hardware setup, and compatibility findings.
In my “Java on Single Board Computers” series, I already published several posts and videos in which I unpack the board, connect it for the first time, and try to install and run some simple Java code. In this post, I want to share some benchmarks of Java on these boards to get a better idea of the performance we can expect from Java on these platforms.
After my initial struggles with the BeagleV-Fire in a previous video, I succeeded in getting Java 25 running on RISC-V-powered BeagleV-Fire! Let me walk you through the journey and the steps I took to make it work.
As part of my 2026 learning goals around Java on RISC-V (see this post about x86 versus ARM versus RISC-V), I’ve asked various suppliers to send me evaluation boards. I already published these:
As part of my 2026 learning goals around Java on Single Board Computers and RISC-V (see this post about x86 versus ARM versus RISC-V), I’ve been asking various suppliers to send me evaluation boards. After testing the LattePanda IOTA, I received two boards from OrangePi to evaluate: the OrangePi 5 Ultra (ARM) and the OrangePi RV2 (RISC-V).
Ever since I started my #JavaOnRaspberryPi journey in 2019, which resulted in my book “Getting Started with Java on the Raspberry Pi”, I’ve been fascinated with these tiny, inexpensive computers. For 2026, I’ve set one of my goals to experiment with Java on various Single-Board Computers (SBC), going beyond my “Raspberry Pi comfort zone.” The market is flooded with SBCs ranging from budget boards (tens of euros) to powerhouses (hundreds of euros). One of the reasons of this price range is the difference between the processors they use. Raspberry Pi uses an ARM processor, but RISC-V is gaining momentum, while Intel maintains its presence. So before I start experimenting, now is the perfect time to compare these three processor families and understand their differences.
