AMD vs AVGO: Merchant GPU vs Custom Silicon — Two Different AI Chip Bets
AMD and Broadcom both win from AI chip spending but through completely opposite approaches. AMD tries to sell general-purpose GPUs to anyone who would otherwise buy Nvidia — competing head-on in the merchant GPU market. Broadcom builds custom silicon specifically for Google, Meta, and Apple, plus dominates the networking chips that connect every AI cluster. One is fighting Nvidia directly; the other is becoming the infrastructure beneath Nvidia's market.
AMD Is Fighting Nvidia Directly — Broadcom Is Building Around It
AMD's MI300X is a genuine GPU that hyperscalers deploy for AI inference workloads. Microsoft has confirmed it, Meta has deployed it, and the chip earns its place in AI clusters alongside Nvidia hardware. AMD's bet is that Nvidia's dominance in training GPUs doesn't automatically translate to inference, where cost matters more and workload specificity matters less. The thesis is sound — but AMD is fighting for every deployment against a competitor with a 15-year software head start.
Broadcom's approach is more surgical. Rather than competing with Nvidia directly, it works with hyperscalers to build chips for their specific workloads. A Google TPU isn't a general GPU — it's a chip that does one thing extremely well (Google's transformer model inference) and does it at a fraction of the cost of a general-purpose GPU. Broadcom earns design fees and long-term manufacturing royalties from these partnerships. And separately, it sells the Ethernet and networking chips that connect every AI cluster, regardless of which GPU brand runs in it.
Business Comparison
- MI300X AI GPU — real inference deployments
- EPYC CPU: 30%+ data center server share
- ROCm software improving, still behind CUDA
- Fabless — manufacturing via TSMC N3/N5
- Higher growth potential if AI GPU scales to $10B+
- Custom XPUs for Google, Meta, Apple
- AI networking: Ethernet ASICs, silicon photonics
- VMware software: $4B+ recurring annual revenue
- ~1.5-2% dividend, growing for 15+ years
- Less volatile — diversified revenue reduces AI cycle risk
Broadcom's VMware Acquisition Changed Its Risk Profile
When Broadcom acquired VMware in 2023 for $69B, it was controversial. But two years later the strategic logic is clear: VMware's virtualization software gives Broadcom $4B+ in recurring annual software revenue that is not correlated with semiconductor cycles. When chip demand slows, software revenue holds. When hyperscaler AI capex pulls back, enterprise software customers keep paying subscriptions.
AMD has no comparable buffer. Its revenue is entirely semiconductor-driven — CPUs and GPUs. When PC sales slow or data center spending pauses, AMD's revenue shows it directly. Broadcom's VMware revenue smooths the cycle, supports the dividend, and funds R&D without requiring semiconductor markets to cooperate. This makes AVGO a structurally more defensive position than AMD, even though both are classified as semiconductor companies.
Who Should Buy Which
Technical Signals — What to Watch
- AMD RSI: AMD is more volatile — RSI swings from below 30 on earnings misses to above 70 on AI GPU announcements. RSI below 35 after fear-driven selloffs has historically been a medium-term buying opportunity.
- AVGO technicals: Broadcom is smoother and steadier. It respects the 50-day EMA in uptrends and moves on earnings beats with less drama than AMD. Earnings gaps in AVGO tend to hold as support better than AMD's.
- AMD key metric: Quarterly MI300X / AI GPU revenue and full-year AI GPU guidance. Any significant upward revision moves AMD sharply higher.
- AVGO key metric: Custom silicon revenue guidance and new hyperscaler customer announcements. The market re-rates AVGO when it wins new XPU partnerships.
