The Raspberry Pi 5 is still the default answer to "which single-board computer should I buy," and for most people it should be. But "default" and "best for your project" are different questions. If you are hitting a wall on RAM, on PCIe bandwidth, on NPU access, or on x86 software compatibility, there are boards that beat the Pi 5 outright on those specific axes, and several of them cost about the same.
Quick Picks
- Best overall Pi 5 alternative: Radxa ROCK 5B — RK3588 octa-core, 6 TOPS NPU, PCIe 3.0 x4 NVMe, 2.5GbE, from $59.
- Best for storage and networking: FriendlyElec NanoPC-T6 — same SoC, LPDDR5, dual 2.5GbE, $109 to $139.
- Best maximum-RAM board: Orange Pi 5 Plus — up to 32GB LPDDR5, Wi-Fi 6E, HDMI 2.1.
- Best when you need x86: UP Xtreme i11 — Core i7-1165G7, Iris Xe, dual 2.5GbE, $299 to $399.
- Still the safe default: Raspberry Pi 5 (8GB) — nothing else matches its documentation and software ecosystem.
What the Pi 5 Actually Gives You, and Where It Stops
The Pi 5 runs a Broadcom BCM2712: four Cortex-A76 cores at 2.4GHz, VideoCore VII graphics, 2GB to 16GB of LPDDR4X depending on variant, dual micro-HDMI at 4Kp60, Gigabit Ethernet, Wi-Fi 5. That is a real generational jump over the Pi 4's Cortex-A72 at 1.8GHz, and for a media center, a home automation hub, a classroom board, or almost any GPIO project, it is more than sufficient.
Three limits push people off it. First, PCIe: the Pi 5 exposes a single lane of PCIe 2.0 through an FFC connector, which needs a HAT and delivers roughly 450MB/s after overhead. Second, Ethernet tops out at Gigabit. Third, there is no NPU at all, so anything involving on-device inference runs on the CPU or an external accelerator.
If none of those three matter to your project, stop reading and buy the Pi 5. If one of them does, the rest of this guide is for you.
RK3588 Boards: The Real Step Up
The Rockchip RK3588 is the SoC that made "Pi alternative" a serious category rather than a compromise. Four Cortex-A76 performance cores plus four Cortex-A55 efficiency cores, a Mali-G610 MP4 GPU, a 6 TOPS NPU, and 8K30 H.265/VP9 plus 4K60 AV1 hardware decode.
The Radxa ROCK 5B is the cheapest credible way into that silicon. A full-size M.2 M-key slot gives you PCIe 3.0 x4 for NVMe — four lanes of Gen 3, not one lane of Gen 2 through an adapter — plus 2.5GbE, dual HDMI with one output capable of 8K30, and 2x USB 3.0. At $59 for 4GB, $79 for 8GB and $99 for 16GB, it undercuts the equivalent Pi 5 variants while roughly doubling CPU throughput.
The FriendlyElec NanoPC-T6 takes the same SoC and spends the extra money where a server build needs it: LPDDR5 instead of LPDDR4X, two 2.5GbE ports instead of one, Wi-Fi 6 on an M.2 E-key slot, an onboard RTC, and 12V barrel-jack power for always-on duty. On a 128 x 105mm board it is bigger than a Pi, and that is the point — it is built to be a small server, not a hobby board.
The Orange Pi 5 Plus is the RAM answer. Up to 32GB LPDDR5 puts it in range of workloads that simply will not fit on a 16GB board, and it adds Wi-Fi 6E and HDMI 2.1.
The Catch: Mainline Kernel Support
This is the part most roundups skip. A Pi 5 and an RK3588 board both list "Debian, Ubuntu." They are not the same product. Raspberry Pi boards run on a mainline kernel with first-party image support and a published support horizon out to 2036. RK3588 mainline support is still partial: as of late 2024 the SoC could not output HDMI on a mainline kernel at all, MIPI DSI was targeted at 6.14, and the NPU driver remained unupstreamed.
In practice that means RK3588 boards run well on vendor images and on Armbian, and less well on a stock upstream distro. If you want to install whatever Debian release you like in five years and have it just work, that is a real argument for the Pi. If you are happy on a vendor or Armbian image, it is not a problem today.
When You Need an NPU
The Pi 5 has no AI accelerator. Every RK3588 board above has a 6 TOPS NPU reachable through Rockchip's RKNN toolkit, which is enough for object detection, pose estimation, classification, and similar edge-vision work at usable frame rates. If inference is the point of your build, this is the single clearest reason to leave the Pi platform.
When You Need x86
Some software has no ARM build and never will. Industrial control stacks, legacy Windows applications, and a long tail of vendor tooling all fall into this bucket, and no amount of ARM performance fixes it.
The UP Xtreme i11 is the answer at the high end: an Intel Core i7-1165G7 Tiger Lake chip boosting to 4.7GHz, Iris Xe graphics that can run OpenVINO-accelerated inference, 16GB LPDDR4X, M.2 NVMe, dual 2.5GbE, and a 40-pin GPIO header on a 115 x 78mm board. It has a configurable 12-28W TDP and extended temperature options on select SKUs.
It is also $399 for the i7, $349 for the i5 and $299 for the i3 — three to four times an RK3588 board. Buy it because you need x86 compatibility or laptop-class single-thread performance, not because you want a faster Pi.

Winner: Radxa ROCK 5B
For most people leaving the Pi 5, the Radxa ROCK 5B is the board to buy. It is the cheapest entry to RK3588, it fixes all three of the Pi 5's real limits at once — four lanes of Gen 3 PCIe, 2.5GbE, a 6 TOPS NPU — and at $79 for 8GB it costs less than the equivalent Pi 5. The trade is documentation depth and mainline kernel maturity, and if you are comfortable on Armbian or a vendor image, that trade is worth making.
Pick the NanoPC-T6 instead if the build is a router, firewall or NAS where the second 2.5GbE port earns its keep. Pick the Orange Pi 5 Plus if you need more than 16GB. Pick the UP Xtreme i11 if the software is x86-only. And stay on the Pi 5 if none of those apply, because the ecosystem is genuinely worth something the day a build breaks.
