Short answer: Сайт RK3568 vs AM62x decision splits along one clear line: AI capability versus contractual longevity. The ieeker YKR-RK3568 development board includes a 1.0 TOPS NPU, four simultaneous display outputs, and PCIe 3.0 — all absent or limited on AM62x — at a lower system cost. The TI AM62x has no dedicated NPU (AI runs on CPU/Neon SIMD only) but offers a Cortex-M4F real-time co-processor, a built-in Hardware Security Module, and TI's documented 15–20 year longevity program — the deciding factor for medical, automotive-adjacent, and long-lifecycle industrial programs where a written supply commitment is a contractual requirement.
Сайт RK3568 vs AM62x comparison comes up constantly for engineers scoping mid-range industrial embedded projects — HMI panels, IoT gateways, and connectivity modules where an i.MX8M Plus or RK3588 would be overkill on cost. Both SoCs target the same quad-core Cortex-A53/A55 performance class and the same 5–10W power envelope, but they come from very different design philosophies: Rockchip builds for multimedia-heavy consumer-adjacent industrial applications with AI inference; TI builds for long-lifecycle industrial and automotive-grade deployments with functional safety and security as first-class features.
This guide breaks down the RK3568 vs AM62x trade-offs across NPU/AI capability, real-time co-processor, display and multimedia, security architecture, industrial interfaces, longevity program, and BOM cost — with a clear decision framework for which platform fits your project.

The AI Capability Gap: RK3568's NPU vs AM62x's CPU-Only AI
The single most significant technical difference in the RK3568 vs AM62x comparison is AI inference capability — and it's not a close call. The RK3568 includes a dedicated 1.0 TOPS NPU using the RKNN architecture, the same toolchain used across Rockchip's RK3566/RK3568/RK3588 family. The AM62x has no dedicated neural processing unit at all. TI's own positioning describes AM62x AI capability as software running on the Cortex-A53 cores' Neon SIMD units, suitable for "simple AI functions such as face recognition and other HMI enhancements" — not real-time object detection or multi-class inference.
In practical terms: a YOLOv5s object detection model that runs at ~22fps on the RK3568's NPU via RKNN-Toolkit2 would run at well under 1fps on AM62x's CPU-only inference — Neon SIMD acceleration helps with simple operations (basic face detection via Haar cascades, lightweight keyword spotting) but cannot deliver real-time inference for modern CNN-based vision models.
If your project roadmap includes any of the following, the RK3568's NPU is a hard requirement that AM62x cannot satisfy without an external AI accelerator (adding cost, board space, and a PCIe or USB dependency that AM62x's lack of PCIe makes awkward): defect detection, face recognition at video frame rates, gesture recognition, predictive maintenance using CNN/LSTM models, or any vision-based quality inspection. For applications with genuinely no AI/ML requirement — pure data acquisition, protocol conversion, basic HMI display — this gap is irrelevant and AM62x's other strengths become more relevant.
RK3568 vs AM62x: Real-Time Control and Hardware Security
Where AM62x pulls ahead in the RK3568 vs AM62x comparison is in two areas that matter for safety-relevant and security-sensitive industrial designs: real-time I/O and hardware security architecture.
Cortex-M4F + PRU-ICSS: Isolated Real-Time Domain
The AM62x integrates a Cortex-M4F running at 400MHz plus a dual-core PRU-ICSS (Programmable Real-time Unit) — both isolated from the Linux application cores with their own memory and I/O. As Toradex documents for the Verdin AM62, this heterogeneous architecture allows offloading hard real-time tasks to the M4 for extremely low latency, with TI providing FreeRTOS tooling for this purpose. The PRU-ICSS additionally enables bit-banged real-time I/O protocols (custom encoder interfaces, EtherCAT slave implementations, precise PWM generation) that would be impossible on a general-purpose Linux CPU.
The RK3568 has no equivalent isolated real-time domain. A PREEMPT_RT-patched Linux kernel on RK3568 achieves good soft real-time performance (180-220µs typical interrupt latency, as covered in our RK3568 vs i.MX8M Plus comparison), but this is fundamentally different from a dedicated, isolated MCU domain that continues operating even if the Linux side crashes or is mid-reboot.
Hardware Security Module: AM62x's Built-In Crypto Engine
The AM62x includes a dedicated Hardware Security Module (HSM) with a user-programmable secure core, session-aware cryptographic engine, and dedicated security DMA — purpose-built for secure boot chains, encrypted firmware images, and key management that's isolated from the main application processor. This is meaningfully more robust than the RK3568's secure boot implementation, which relies on the main CPU's TrustZone rather than a physically separate security domain.
For products requiring formal security certifications (Common Criteria, IEC 62443 for industrial cybersecurity) or handling sensitive cryptographic operations (payment terminals, secure access control, encrypted data loggers), AM62x's HSM provides a hardware foundation that simplifies certification. For typical industrial HMI and gateway products without these specific certification requirements, RK3568's secure boot is adequate.
From the Factory Floor: A Medical Device Startup's AM62x vs RK3568 Decision
About a year ago, we were contacted by a medical device startup in the Netherlands developing a portable diagnostic device — a handheld unit combining a 5-inch touch display, a custom optical sensor module, Bluetooth connectivity to a companion app, and an embedded ML model for preliminary result classification. They had been evaluating both AM62x and RK3568 platforms and asked us for an honest assessment, given that we manufacture RK3568 boards.
Their requirements pulled in both directions. The ML classification model — a CNN trained on their optical sensor data — needed real-time inference at the point of measurement, which pointed toward RK3568's NPU. But their device was pursuing Class IIa medical device certification under EU MDR, which placed significant weight on documented component longevity (a 10-year minimum supply commitment was part of their regulatory submission strategy) and security architecture documentation for their data handling subsystem — both factors favoring AM62x.
We gave them a direct recommendation: prototype on RK3568 first to validate the ML model's real-world accuracy and inference timing, because if the model couldn't hit their required <2-second result time on AM62x's CPU-only inference, the AM62x path was a non-starter regardless of its other advantages. We supplied a YKR-RK3568 evaluation board, and their ML team validated their quantized model at 380ms inference time — well within spec, with significant headroom.
With the AI requirement satisfied on RK3568, the remaining question was the 10-year longevity commitment. We worked with them on an alternative path: rather than relying solely on Rockchip's SoC-level commitment, we structured a bonded inventory agreement covering their projected 10-year unit volume based on their regulatory submission's worst-case demand forecast, combined with our written component change notification (ECN) policy. Their regulatory consultant confirmed this satisfied the MDR technical documentation requirement for supply chain risk — a written supplier commitment plus inventory buffer was an acceptable equivalent to a chip-vendor longevity program for their risk classification.
Their device passed MDR technical file review eleven months later, with the RK3568-based design and our supply agreement cited in the supply chain risk section without further questions. The lesson: AM62x's TI longevity program is valuable but not the only path to satisfying long-lifecycle supply requirements — and when AI capability is a hard requirement, it's worth exploring supplier-level commitments before defaulting to AM62x on longevity grounds alone.
Display, Multimedia, and Industrial Interface Comparison
Beyond AI and real-time architecture, the RK3568 and AM62x diverge significantly in display capability and expansion interfaces — relevant for HMI panels, gateways, and multi-peripheral industrial designs.
Display: RK3568's 4-Output Advantage
The RK3568 supports up to four simultaneous display outputs (MIPI DSI, dual LVDS, eDP, HDMI 2.0) and 4K H.265/H.264 video decode at 60fps. AM62x (AM625 variant) supports dual LVDS or LVDS+HDMI — two outputs — with video decode limited to 1080p. For single-panel HMI applications, both are sufficient. For dual-display configurations (operator panel + supervisor display, or primary display + camera preview), RK3568's headroom is meaningfully larger. For details on RK3568's display interface selection (LVDS vs MIPI DSI vs eDP) for industrial HMI design, see our RK3568 HMI panel guide.
Networking: TSN Switch vs Dual Independent MACs
AM62x's integrated 3-port Gigabit Ethernet switch with Time-Sensitive Networking (TSN) support is a genuine differentiator for industrial Ethernet applications — PROFINET IRT, EtherCAT, and other deterministic Ethernet protocols benefit directly from TSN-capable switching at the SoC level, without external switch ICs. RK3568's dual independent GbE MACs serve a different purpose: LAN/WAN separation for gateway architectures (as covered in our RK3568 IoT gateway guide), not deterministic real-time Ethernet. If your application is a TSN-based industrial Ethernet node, AM62x's integrated switch is the better architectural fit.
Expansion: PCIe and SATA Absence on AM62x
RK3568's PCIe 3.0 ×2 and SATA III enable straightforward 4G/5G modem integration, NVMe/SSD storage, and additional expansion cards. AM62x has neither — expansion is limited to USB, SDIO (for Wi-Fi/BT modules), and the CAN-FD/serial interfaces via PRU. For IoT gateway designs requiring cellular connectivity and local data historian storage, AM62x's lack of PCIe means cellular modems connect via USB (functional but less elegant than PCIe M.2) and there's no path to SATA SSD storage — eMMC or SD card only.
RK3568 vs AM62x: The Decision Guide
Choose the ieeker YKR-RK3568 if:
- Your application includes any AI/ML inference — object detection, face recognition, anomaly detection, visual quality inspection. AM62x's CPU-only AI cannot run these workloads in real time.
- You need more than 2 simultaneous display outputs or 4K video decode — RK3568's Mali-G52 and 4-output display controller provide significant headroom over AM62x
- Your design requires PCIe (cellular modem, NVMe SSD) или SATA storage — AM62x has neither natively
- You need strong Android support — RK3568's Android 12 BSP is actively maintained; AM62x is Linux/Yocto-focused with no Android path
- Your supply chain risk can be addressed via supplier-level commitments (bonded inventory, written ECN policy) rather than requiring a chip-vendor 15-year+ program specifically
Choose the AM62x if:
- Your project has zero AI/ML inference requirement — pure HMI display, data acquisition, or protocol conversion with no vision or pattern-recognition workload
- You need an isolated real-time domain — Cortex-M4F + PRU-ICSS for hard real-time control loops, custom encoder protocols, or EtherCAT/PROFINET slave implementations
- Your product requires TSN-capable Ethernet switching at the SoC level for deterministic industrial Ethernet
- Your regulatory submission specifically requires a documented 15–20 year chip-vendor longevity program as part of the supply chain risk assessment, and supplier-level alternatives are not acceptable to your certification body
- Your design benefits from a dedicated Hardware Security Module for formal security certification (IEC 62443, Common Criteria)
IEEKER YKR-RK3568 for Industrial Embedded Projects
The ieeker YKR-RK3568 development board brings the RK3568's 1.0 TOPS NPU, 4-display-output capability, dual GbE, PCIe 3.0, and SATA III to industrial projects — manufactured in-house with validated Buildroot, Debian 11, Ubuntu 22.04, and Android 12 images. For teams weighing the RK3568 vs AM62x decision where AI capability is on the requirements list — even tentatively — we recommend prototyping on RK3568 first, since the AM62x path closes off entirely if CPU-only inference doesn't meet your latency target.
For projects with confirmed 15-year+ longevity contractual requirements where AI is not needed, AM62x-based platforms from TI's partner ecosystem (Toradex, Variscite, Phytec) are well-suited — and we're happy to provide an honest comparison if you're evaluating both. For supply chain risk mitigation as an alternative to chip-vendor longevity programs, see our embedded board manufacturer evaluation guide covering bonded inventory and ECN policy structures.

→ Request YKR-RK3568 Evaluation Board →Часто задаваемые вопросы
Does AM62x have an NPU?
No. The AM62x family (AM623/AM625) has no dedicated Neural Processing Unit. AI/ML workloads run on the Cortex-A53 cores' Neon SIMD instructions, which TI describes as suitable for "simple AI functions such as face recognition and other HMI enhancements" rather than real-time object detection. If your application needs CNN-based vision inference at video frame rates, RK3568's 1.0 TOPS NPU is required — AM62x cannot do this without an external accelerator.
Is RK3568 or AM62x better for an HMI panel?
RK3568 for most HMI panels — it supports more display outputs (up to 4 vs AM62x's 2), 4K video decode vs AM62x's 1080p, and has a more capable GPU. If the HMI also needs vision-based features (face recognition login, visual inspection results display), RK3568's NPU is required. AM62x remains a viable choice for simple single-display HMI panels with no AI requirement, especially where TSN Ethernet or a 15-year longevity commitment matters more than display capability.
What is PRU-ICSS on the AM62x?
PRU-ICSS (Programmable Real-time Unit and Industrial Communication Subsystem) is a pair of small, fast, deterministic co-processors integrated into TI Sitara SoCs including AM62x. They run independently of the main Linux cores and are used for bit-banged real-time protocols — custom encoder reading, precise PWM generation, and industrial fieldbus protocol implementations like EtherCAT slave or Profibus that require microsecond-level timing the main CPU cannot guarantee under Linux scheduling.
Can RK3568 match TI's 15-year longevity program?
Rockchip does not publish a chip-level 15-20 year longevity program equivalent to TI's. The RK3568J industrial-grade variant has extended availability, but for programs with a hard 15-year+ contractual requirement, this is a genuine gap. However, supplier-level commitments — bonded inventory programs, written Engineering Change Notice (ECN) policies, and Last Time Buy procedures — can address supply chain risk requirements in many regulatory frameworks, as covered in our supplier evaluation guide. Whether this is acceptable depends on your specific certification body's requirements.
What is Time-Sensitive Networking (TSN) and do I need it?
Time-Sensitive Networking (TSN) is a set of IEEE 802.1 standards that enable deterministic, low-latency Ethernet communication suitable for industrial control. You need TSN if your application implements PROFINET IRT, EtherCAT-over-TSN, or other deterministic industrial Ethernet protocols requiring guaranteed bounded latency. For standard Modbus TCP, OPC UA, or MQTT-based gateways (the majority of IoT gateway applications), TSN is not required and RK3568's standard dual GbE is sufficient. See our RK3568 IoT gateway guide for typical gateway networking architecture.
