Google, Not Nvidia, May Be the Real Threat to AMD's AI Position

Alphabet's Cloud operating income tripled to $11.121 billion from $3.594 billion, and the quarter it did so also showed why AMD's second place in AI accelerators looks less secure than the standings suggest. The rival now bidding for accelerator budgets is not Nvidia. It is a customer.

AMD (NASDAQ: AMD) and Alphabet (NASDAQ: GOOGL) reported third-quarter results within a week of each other, and both reports describe the same contest: AI accelerators. Investors usually frame AMD's competition as Nvidia (NASDAQ: NVDA). Google may be the quieter threat, because TPU racks sold through Google Cloud can fill data center slots an Instinct GPU could have taken.

What did AMD's quarter actually deliver?

The numbers are strong. AMD posted revenue of $13.377 billion, up 44.7%. Data Center revenue reached $8.546 billion, and the segment's operating margin rose to 34% from 25%. That jump shows Instinct GPUs and EPYC CPUs scaling profitably rather than buying share. Lead customers, including Anthropic and OpenAI, brought their first Helios racks online during the quarter.

Not everything cooperated. Gaming revenue fell 40% to $773 million as console chip sales slowed. A 40% decline in one segment is the kind of detail that keeps a chief financial officer awake.

How fast is Google's accelerator business growing?

Faster each quarter, which is the part AMD shareholders should reread. Google Cloud revenue growth accelerated from 48% in the fourth quarter of 2025 to 63%, then 82%, then 103%. Growth at that pace does not usually reverse on its own.

Sundar Pichai said on the results: "We're also seeing strong demand for our TPU systems across a wide range of customers." The phrase "a wide range" remains vague, and analysts have no roster of named TPU buyers yet. Earlier reporting suggested TPU volume could triple to 8.8 million units by 2027, though that figure is a projection rather than a confirmed order book.

The commercial structures differ sharply:

• AMD sells merchant silicon: Instinct GPUs and Helios racks to whoever will buy them.
• Google sells chips, cloud capacity and Gemini models as one integrated stack.
• AMD's weak spot this quarter was Gaming, down 40%.
• Alphabet's weak spot is free cash flow of -$9.065 billion.

What happens when a supplier competes with its customer?

On AMD's earnings call, analysts pressed CEO Lisa Su on custom chips designed by customers. She answered: "The key is for us to continue to show that TCO advantage across workloads." AMD is designing MI500 and MI600 together with frontier labs, and it is buying Taalas for specialized inference silicon. Those moves show the company takes custom silicon seriously.

Here the geometry turns awkward. Google Cloud runs instances on 5th Gen AMD EPYC CPUs, so AMD still sells Google processors even as TPUs compete for accelerator budgets. Alphabet's quarterly capital spending hit $51.355 billion, up 114%. That is the price of building out a full stack, and it is roughly four times AMD's entire quarterly revenue.

Will fourth-quarter Helios shipments hold the line?

AMD guided fourth-quarter revenue to about $17 billion, plus or minus 3%. Su also said "demand is higher than supply." Shortage is flattering until it is not; impatient buyers with workloads to run can move toward TPU capacity while Helios allocation sorts itself out.

The market has already picked its favorite. AMD expects revenue to grow more than 80% in 2027, and its shares are up 158.17% year to date. Alphabet's shares are down 6.06% over the same stretch. AMD remains the purer AI hardware growth story; Alphabet trades at a P/E near 13, a valuation that reflects a business still supported by Search, but its negative free cash flow argues for caution on both sides of the trade.

The test ahead is specific. If TPUs start appearing at labs now running Helios, AMD's accelerator position faces a direct challenge from a company that also buys its server CPUs.
