Business Model
What each company does and how it makes money
Ambiq Micro designs ultra-low-power semiconductor chips for battery-powered IoT and wearable devices. It generates revenue primarily from selling its Apollo system-on-chip and Atomiq AI accelerator products — with technical support services as a secondary stream — through a global sales representative network. The company's key advantage is its proprietary subthreshold power-optimized technology that enables significantly longer battery life than conventional chips, creating a strong moat in power-sensitive edge AI applications.
Advanced Micro Devices designs and sells high-performance computing and graphics processors for PCs, data centers, gaming consoles, and embedded systems. It generates revenue primarily from sales of CPUs (~50% of revenue) and GPUs (~30%), with the remainder coming from semi-custom chips for game consoles and embedded processors. AMD's key advantage is its competitive x86 CPU architecture and GPU technology that directly challenges market leader Intel in performance-per-dollar across multiple segments.
