The Qualcomm Dragonwing Q-2390 and IQ-2390 share the same basic compute shape: one Arm Cortex-A78 core, three Cortex-A55 cores, graphics, a Hexagon NPU rated at 1.1 TOPS, and a real-time RISC-V microcontroller. The buying decision is therefore about deployment conditions, connectivity, and lifecycle requirements rather than a simple core-count difference.
What is Q-2390 designed for?
Qualcomm Dragonwing Q-2390 is the commercial-grade option for compact connected products. Qualcomm lists retail, access control, smart-home hubs, media stations, home robots, and enterprise terminals as target applications. Its quad-core CPU runs up to 1.9 GHz, uses LPDDR4x memory up to 8 GB, and combines application processing, GPU, vision, AI, and connectivity on one platform.
The practical advantage is integration. A product designer can divide work between the application CPU, Adreno 704 GPU, Hexagon AI engine, image signal processor, and RISC-V MCU instead of adding several separate controllers.
When is IQ-2390 the better fit?
Qualcomm Dragonwing IQ-2390 is the industrial-grade counterpart. It adds ECC memory protection, an operating range of -30°C to 115°C, time-sensitive networking, industrial packaging, and stated 10-year supply longevity. Those features matter more in a factory controller, machine-vision gateway, PLC, energy meter, or elevator panel than a marginal increase in peak CPU frequency would.
Both parts support Android, Yocto Linux, Ubuntu, and Zephyr in Qualcomm’s product material. The right choice depends on the system’s environment and maintenance horizon: Q-2390 fits commercial designs, while IQ-2390 is structured for harsher conditions and longer deployment cycles.
How should you compare embedded CPUs?
Start with operating temperature, memory error protection, I/O, software support, and product longevity. Only then compare core counts and clock speed. The Qualcomm CPU collection shows the company’s broader Arm lineup, while the compare page is useful when you need to place these edge SoCs beside laptop-oriented Snapdragon entries.
