Same RK3588 Chip, Two Different Boards: Where Kiwi Pi 5 Pro and Orange Pi 5 Plus Split

Two single-board computers can share a processor and still behave very differently once they are deployed. The Kiwi Pi 5 Pro and the Orange Pi 5 Plus are a clear example of how board design, more than silicon, shapes what an RK3588 system is good at.
As Rockchips.net explains in its comparison of the two boards, both are built on the Rockchip RK3588, an 8nm chip with four Cortex-A76 cores at 2.2GHz, four Cortex-A55 cores at 1.8GHz, Mali-G610 MC4 graphics and a triple-core 6 TOPS NPU. Each can decode 8K video at 60fps and encode it at 30fps. In raw computing terms, the two are close: Geekbench 5 scores land within 5% of each other, and the NPU delivers equivalent frame rates in object detection tests.
The first real divergence is in how each board is powered and cooled. The Kiwi Pi 5 Pro takes its power over USB Type-C PD at 12V/2A and relies on a passive heatsink, with a fan available as an option. The Orange Pi 5 Plus uses a 5V/4A barrel connector and ships with an active fan. That choice affects behavior under sustained load. The Orange Pi throttles later thanks to its fan, but it draws 10 to 15% more power under load, while the Kiwi Pi stays cooler in passive setups. At idle, both sit at roughly 3W.
Memory and storage defaults point in different directions as well. The Kiwi Pi 5 Pro starts with 8GB of LPDDR4X, configurable up to 32GB, and 128GB of eMMC that can grow to 512GB. It adds a PCIe 3.0 x4 M.2 2280 slot and a TF card slot. The Orange Pi 5 Plus comes with 16GB of LPDDR4/4X and a 32GB eMMC base model, alongside an M.2 NVMe slot and its own TF card slot. According to the comparison, memory bandwidth favors the Kiwi Pi's LPDDR4X configuration.
Networking is where the gap becomes operationally significant. The Kiwi Pi 5 Pro has two 2.5G RJ45 ports, Wi-Fi 6 with Bluetooth 5.4 and an M.2 slot for 4G or 5G modules. The Orange Pi 5 Plus offers one 2.5G port, Wi-Fi 6 with Bluetooth 5.0 and no cellular option. For anyone building a gateway, firewall or remote node, a second wired port and a cellular fallback change what the board can do without extra adapters.
Display and expansion follow the same pattern. The Kiwi Pi 5 Pro drives two screens through HDMI 2.1 and HDMI 2.0, adds MIPI-DSI and MIPI-CSI camera interfaces, and carries 60-pin, 50-pin and 39-pin headers. Its USB set includes four USB 3.0 host ports and a USB-C port with USB 3.1, DisplayPort Alt Mode and PD. The Orange Pi 5 Plus has a single HDMI 2.1 output with MIPI-DSI and eDP options, two USB 3.0 and two USB 2.0 ports, and a standard 40-pin GPIO header.
On software, both support mainline Linux kernel development, GPU and NPU acceleration, TensorFlow Lite and PyTorch. The Kiwi Pi 5 Pro lists Android 15, Ubuntu 22.04 LTS and Debian 11 with Linux 5.10 and 6.10 kernels, backed by detailed technical manuals and schematics. The Orange Pi 5 Plus supports Orange Pi OS in Android and Debian variants, Ubuntu 20.04 and 22.04, Debian 11 and a range of community distributions, with documentation that leans more on its community.
The result is a division of roles. The Kiwi Pi 5 Pro fits network appliances, multi-display systems, industrial automation and remote deployments, while the Orange Pi 5 Plus suits media centers, general-purpose computing and budget-conscious projects that benefit from community support.
