# RK3588 boards (Orange Pi 5, Banana Pi BPI-M7, Radxa ROCK 5B): what they share and where they differ

> The Rockchip RK3588/RK3588S family (4x Cortex-A76 + 4x Cortex-A55, 6 TOPS NPU) powers many high-end Raspberry Pi alternatives. The boards differ mainly in PCIe lanes to the NVMe slot, Ethernet speed, header size and software support.

## The shared SoC

Rockchip's **RK3588** (and the reduced-I/O **RK3588S**): 8 nm, **4x Cortex-A76 + 4x Cortex-A55**, a **6 TOPS** triple-core NPU (INT4/INT8/INT16/FP16 and more), and rich high-speed I/O (PCIe 3.0/2.0, SATA, USB 3.1, multiple camera inputs). CPU performance is broadly similar across boards; the **board design and software** make the difference.

## Board differences (from the vendors' pages)

| | Orange Pi 5 | Banana Pi BPI-M7 | Radxa ROCK 5B |
|---|---|---|---|
| SoC | RK3588S | RK3588 | RK3588 |
| RAM options | 4 / 8 / 16 GB LPDDR4/4X | 8 / 16 / 32 GB LPDDR4/4x | several options; check the exact variant |
| NVMe slot | M.2 M-key, **PCIe 2.0** | M.2 Key M, **PCIe 3.0 x4** | M.2 M Key, **PCIe 3.0** (no M.2 SATA) |
| Ethernet | 1 GbE | **2x 2.5 GbE** | **2.5 GbE with PoE** (PoE HAT needed) |
| Onboard eMMC | no (microSD, NVMe) | yes | eMMC module connector |
| Header | **26-pin** | 40-pin | 40-pin |

## Picking one

- **NVMe throughput matters** (databases, NVR recordings): prefer a PCIe 3.0 slot (BPI-M7, ROCK 5B).
- **Network appliance or router-like duties**: dual 2.5G (BPI-M7), or PoE-powered installations (ROCK 5B with PoE HAT).
- **Maximum RAM for local LLMs or many containers**: check the largest RAM option actually in stock.
- **NPU use**: the NPU needs Rockchip's runtime (RKNN) and a kernel with the NPU driver. Verify that your chosen OS image supports it; many generic images don't.
- Across all of them: check OS support first (see the OS-choice item). The board with the best-maintained image beats the one with the best spec sheet.

## Claims

- The Rockchip RK3588 is built on an 8 nm process with quad-core Cortex-A76 plus quad-core Cortex-A55 CPUs and a 6 TOPS triple-core NPU. (unverified)
- The Orange Pi 5's M.2 socket uses PCIe 2.0, while the Banana Pi BPI-M7 and Radxa ROCK 5B provide PCIe 3.0 on their M.2 M Key slots. (unverified)
