Broadcom's AI Surge: Custom Chips Dominate

Broadcom's fiscal third quarter saw an impressive 85.5% revenue increase to $29.59B, with AI semiconductor revenue jumping 221% to $16.70B. Custom XPUs accounted for 73% of this AI revenue, with major clients like Google and Meta securing multi-generation deals for Broadcom's accelerators.

AMD's second quarter revenue grew 50.1% to $11.54B, driven by a 107% surge in Data Center sales to $6.72B, now comprising 58% of its total revenue. The company's AI efforts are centered on its Instinct GPUs and EPYC CPUs, with its Helios system aiming to offer competitive performance.

Broadcom CEO Hock Tan asserted that custom-developed chips optimized for specific AI workloads surpass any GPU in performance and cost. AMD counters with its Helios system, claiming improved token efficiency per dollar, with both OpenAI and Meta distributing their orders across multiple suppliers.

Looking ahead, AMD forecasts third-quarter revenue around $13B, marking the start of its Helios ramp. Broadcom anticipates fourth-quarter AI revenue to reach $21.7B, up 236%, though its gross margins are expected to moderate slightly as custom chip sales increase. Supply chain constraints for land, power, and substrates will be critical for Broadcom's capacity realization.

Year-to-date, AMD has seen substantial stock growth, trading at a high P/E ratio near 245, making its valuation sensitive to performance. Broadcom, with $13.66B in free cash flow, offers more stable fundamentals and long-term customer contracts, positioning it favorably against AMD's direct competition with Nvidia.
