Broadcom, AMD, and Nvidia have been talking about artificial intelligence (AI) more than any other companies, according to an analysis of more than 200 major technology players' earnings calls.

The DealHub study looked at the number of times AI, generative AI (genAI), and ChatGPT were mentioned 10 sentences before or after a sales-related phrase like "revenue" or "earnings". Each company's number of AI references per 100,000 words represents a score on the AI-Sales Index.

Broadcom executives mentioned AI technology 223 times for every 100,000 words in the company's latest two earnings calls, representing the highest ratio of any company measured in the study. The soon-to-be owner of VMware made its mark on the ecosystem as a supplier of chips for Ethernet switches and launched an AI-optimized chip earlier this year, Jericho3-AI.

And in October the chipmaker debuted a high-performance, low-power chip ideal for AI networking use cases — a 5 nm 200 G/lane optical pulse amplitude modulation (PAM) digital signal processor (DSP) known as the Sian BCM85822.

“It is primarily meant for 1.6 T deployments in traditional data center networks, but it also lays the foundation for next-generation 1.6 T/3.2 T deployments in AI [artificial intelligence] clusters,” Natarajan Ramachandran, director of product line management at Broadcom, told SDxCentral.

Broadcom estimates the BCM85822 could enable a 51.2 terabit switching capacity within a single rack unit, significantly boosting network density for cloud providers as they race to be the best home for AI workloads.

AMD, Nvidia follow closely as Google trails — but where's Microsoft?

AMD, which specializes in semiconductor manufacturing for high-performance computing, took second place with 190 mentions of AI per 100,000 words. The company announced its intent to acquire AI startup Nod.ai last month, and its MI300 GPU has garnered significant enterprise interest.

Though Nvidia's tenure in the GPU world has well-positioned it to capitalize on the growth of AI, the company's executives aren't as persistent in their use of AI terminology when communicating with shareholders during quarterly earnings conferences. The study found 160 mentions of AI per 100,000 words, placing Nvidia third on the list.

Other notably-scoring companies include Thomson Reuters at 159 mentions, tax preparation and business finances software provider Intuit (153), Salesforce (128), Alphabet (119) and S&P Global (119), followed by internet gaming company NetEase (107) and Adobe (103).

Though AI infrastructure is inextricably linked with hyperscale cloud providers like Google Cloud, Amazon Web Services (AWS) and Microsoft Azure, the data suggests the AI rush hasn't quite hit the cloud — the hardware is what's more important in today's growing ecosystem.

Google Cloud's parent company Alphabet, for example, has more than just AI eggs in its basket and tends to devote energy to areas of the business like advertising, Google Workspace and enterprise offerings.

But Microsoft and AWS didn't even make the top 10 list, despite the former's significant investments in ChatGPT creator OpenAI and the latter's dominance in the cloud computing market.
