Is RK3568 worth it over RK3566 for a consumer product?

Rarely. The extra cost buys PCIe, SATA, dual Ethernet and triple display. Consumer products usually do not use them, so the RK3566 board is the better value.

Does RK3588 need active cooling?

Under sustained NPU or multi-stream decode load, yes in most enclosures. A fanless design has to be validated thermally in DVT, not assumed.

RK3566, RK3568 or RK3588: choosing for a screen-based product

Nearly every Android-based device brief we receive names one of three Rockchip parts: RK3566, RK3568 or RK3588. They are often treated as a price ladder. In practice the differences that decide a project are the ones that show up in the mechanical design and the thermal solution, not in the benchmark.

RK3566: the single-screen workhorse

Quad Cortex-A55 with a Mali-G52 GPU and a 0.8 TOPS NPU, 4K decode and 1080p encode. It is the cheapest way to put a good-looking Android UI on one screen with video playback: kiosks, e-readers, smart speakers with displays, single-screen POS, OTT boxes. If your product has one panel, modest AI and no expansion cards, this is the sensible default.

Watch for: encode. 1080p encode is enough for recording or a video call, not for multi-stream NVR work.

RK3568: the same CPU, different IO

RK3568 shares the A55/G52/0.8 TOPS core but adds the interfaces that industrial products need: full-link ECC memory, its own ISP, triple-display support, PCIe, SATA and dual gigabit Ethernet on typical boards. It is the part for NVRs, gateways, industrial control, face-access terminals and NAS boxes.

Watch for: the price difference buys IO, not compute. If you do not need PCIe, SATA, dual Ethernet or three screens, you are paying for connectors.

RK3588: when the product needs real headroom

Four Cortex-A76 plus four Cortex-A55, Mali-G610, 6 TOPS NPU, 8K decode capability, PCIe 3.0, SATA 3.0 and USB 3.1. This is the part for multi-camera analytics, robotics controllers, edge AI boxes and multi-screen products.

Watch for: thermals and power. An RK3588 board under sustained NPU load needs a real thermal solution and a power budget to match; a fanless 8 mm enclosure will throttle, and the schedule impact lands in DVT, not in the datasheet.

The decision order we use

First, how many displays and at what resolution. Second, does the product encode video continuously. Third, does it need PCIe, SATA or dual Ethernet. Fourth, what thermal budget the enclosure can afford. Those four answers pick the part before price is discussed — and the answer is often the cheaper one.

A note on lifecycle

Parts in this family ship for years, but board designs age: DDR availability, connector EOLs and Android version support all move. For a product with a five-year plan, choose the board vendor for their supply commitment as much as for the SoC.
