If you’ve been shopping for a single-board computer anytime in the last couple of years, you’ve run into this chip. Orange Pi, Radxa, Banana Pi, KiwiPi – what do they all have in common? That’s right: Rockchip RK3588.
The chip launched in 2022, and it’s still not giving up ground. Why? Because it’s genuinely good. 8 cores, decent graphics, built-in NPU, 8K video support, PCIe 3.0. All at a reasonable price. The chip is four years old now, and it’s still dominating the SBC market.
In this article, I’ll break down what this thing actually is, what it’s good for, and why it still matters in 2026. Spoiler: the RK3688 is coming, but the RK3588 isn’t going anywhere.
Right to the point: If you’re already looking at specific RK3588 boards, we’ve got a detailed breakdown of RK3588 SBC options from Orange Pi and Kiwi Pi. That covers models, pricing, and real-world use cases. And if you want to peek into the future, check out the Rockchip RK3688 SBC – but that’s still just a paper launch for now.

What Exactly Is the Rockchip RK3588?
The RK3588 is a system-on-chip (SoC) from Rockchip. In plain English: one small chip that contains everything – CPU, GPU, NPU, memory controllers, and peripheral interfaces.
It replaced the aging RK3399 (which is still limping along in some devices). And it looks like it’s here to stay.
Quick facts:
- 8 cores: four big Cortex-A76 cores up to 2.2-2.4 GHz + four little Cortex-A55 cores up to 1.8 GHz
- Process: 8nm – not the latest, but power-efficient enough
- Graphics: Mali-G610 MC4 with Vulkan 1.2 and OpenCL 2.0 support
- NPU: triple-core, 6 TOPS – for on-device AI without the cloud
Why Everyone Loves This Chip
CPU and GPU – Power and Multimedia
Eight cores in a big.LITTLE setup. When you need performance, the big Cortex-A76 cores kick in. For background tasks, the little Cortex-A55 cores handle things quietly.
The Mali-G610 MC4 GPU can drive up to four displays simultaneously. For gaming, it’s roughly PS2 and Vita level through emulators. For media, it handles 8K without breaking a sweat.
NPU – Local AI Without the Cloud
6 TOPS. That’s not just a marketing number. You can run YOLOv5, ResNet, face recognition, object detection – all locally. No internet, no latency.
For context: the Raspberry Pi 5 has no NPU at all. And the upcoming RK3688 will have 20-30 TOPS, but it’s not out yet.
Video – 8K, Seriously
Decoding: 8K@60fps (H.265, VP9, AV1). Encoding: 8K@30fps (H.265, H.264).
Want a media server? Done. A streaming appliance? Easy. A video wall? Sure, why not.
PCIe 3.0 x4 – Finally
This is arguably the most important feature. You can connect an NVMe SSD without adapters. Or an M.2 AI accelerator. Or even an external GPU (though that’s getting into experimental territory).
Competitors struggle here. The Raspberry Pi 5 has PCIe 2.0. The RK3399 had no PCIe at all. The RK3588 gives you a proper full-speed interface.
What About the RK3588S?
Don’t get confused. There are two versions: the full RK3588 and the cut-down RK3588S. The RK3588 vs RK3588S comparison is worth a read, but here’s the short version:
- RK3588S is a trimmed-down version for budget devices
- Fewer PCIe lanes (only 2.0 x1)
- Fewer video outputs
- Cheaper
If you need a full PC or server, get the RK3588. For compact tablets or smart displays, the RK3588S is fine.
Software – It’s a Thing
It’s not perfect, but it works.
Rockchip provides the RKNN SDK for the NPU. It supports TensorFlow, PyTorch, ONNX, Caffe. The compiler is a bit picky – not all models work without some tinkering. But the community is large, and most problems have already been solved by someone.
Linux support is solid: Ubuntu, Debian, Armbian. Android 12/13 too. There are Batocera builds for retro gaming, LibreELEC for media centers.
The downsides: documentation can be outdated, and proprietary drivers can be annoying. But if you’re not an open-source purist, you’ll manage.
Which Boards Use the RK3588?
Here are the most popular options:
If you think the SBC market is standing still, think again. While Raspberry Pi is preparing the Pi 6 (which won’t arrive until 2028 at the earliest), Rockchip has already announced the RK3688. The Raspberry Pi 6 analysis shows the Pi Foundation is losing momentum. Rockchip has 6 TOPS today, and the RK3688 promises 32 TOPS tomorrow. Raspberry Pi? Just promises.
FAQ
Can I run Windows on the RK3588?
Officially, no. Unofficially, there are Windows on ARM builds, but drivers are a mess. I wouldn’t bother.
What cooler do I need?
It runs hot. Without active cooling (fan + heatsink), it will throttle within 10-15 minutes under load. Idle temps are around 50°C, load temps hit 85-90°C.
How much power does it use?
Idle: 3-5W, under load: 15-20W (with peripherals). Reasonable for an SBC.
Is it good for AI projects?
Yes, the 6 TOPS NPU handles detection, classification, and segmentation well. For large language models, it’s underpowered, but for cameras and robots, it’s the best option.
What’s the difference between RK3588 and RK3588S?
The S version is cut down: fewer ports, PCIe 2.0 x1 instead of 3.0 x4, fewer video outputs. Cheaper, but weaker.
My Take
The RK3588 is the must-have chip of 2022-2026. It hasn’t lost relevance, and it probably won’t for the next couple of years. Sure, the new Rockchip RK3688 will be more powerful, but it’s not out yet. And the Raspberry Pi 6 will have better software, but it won’t ship until 2028.
The RK3588 is available now; it works and is stable. It handles 90% of use cases.
