Rockchip RK3576
A high-tier chip that brings 6 TOPS of AI and 8K@30 decode below the RK3588 price point. The middle path when you need serious NPU performance but not the full flagship.
Boards using it: KTM-S76.
At a glance
| CPU | 4×Cortex-A72 + 4×Cortex-A53, up to 2.2 GHz |
| NPU | 6 TOPS |
| Video decode | 8K@30 |
| Displays | Up to 3 independent |
| Memory | LPDDR4/4X/5 |
What it means for your product
The headline is the 6 TOPS NPU — the same AI tier as RK3588, which makes the RK3576 a strong choice for vision and inference workloads that would overwhelm the ~1 TOPS RK3568. Multi-model or multi-camera analytics are on the table here.
Video decode reaches 8K but at 30 fps (versus RK3588's 8K@60). For signage that is almost always 4K or 1080p in practice, this is ample; 8K@30 is headroom rather than a working resolution.
Three independent displays cover video-wall and multi-screen builds short of the RK3588's four.
Choosing between RK3576 and RK3588
Both give you 6 TOPS. Step up to RK3588 when you specifically need 8K@60, four displays, or the A76 CPU's higher single-thread performance. Otherwise the RK3576 delivers the AI capability at lower cost and heat.
Software
Runs the same firmware and API as every KTM board. NPU deployment is via Rockchip's RKNN toolchain.
