What AI models can the Rockchip RK3566 / RK3568 (8 GB) run?
- RAM
- 8.0 GB
- Usable for models
- 6.4 GB
- Memory bandwidth
- 13 GB/s
- Runs models on
- CPU cores
- Released
- 2021
Models run on the CPU cores here, so the memory’s speed and how fast those cores can read it set the pace: small models (about 1-4B) are usable, bigger ones are slow. We plan around 6.4 GB of the 8.0 GB (what Linux leaves free for a model). 0.8 TOPS NPU (about 1 TOPS on the RK3568) for small vision models through Rockchip’s RKNN toolkit.

| Maker | Rockchip |
|---|---|
| Type | Single-board computer or edge AI board |
| Share of memory for models | 80% (what Linux typically leaves free on a board this size) |
| Chip | Rockchip RK3566 |
| AI accelerator | 0.8 TOPS NPU (about 1 TOPS on the RK3568) for small vision models through Rockchip’s RKNN toolkit. |
| Boards with this chip | Radxa ROCK 3A / 3C / ZERO 3 · Orange Pi 3B · Pine64 Quartz64 · FriendlyElec NanoPi R5S |
| Memory type | LPDDR4/LPDDR4X or DDR4 up to 3200 MT/s, 32-bit |
| Bandwidth figure | 12.8 GB/s, the chip’s rated memory speed |
| Note | 4× Cortex-A55 at 1.8 GHz (RK3566) or 2.0 GHz (RK3568), Mali-G52 2EE GPU, up to 8 GB. Entry level: small models only, at a few tokens per second. Four A55 cores can’t read memory at anything near its rated speed, so we assume 20% (estimate). |
