AI accelerator
Teradyne’s discussion of "AI accelerator" in the transcript centers primarily on the company’s strategic positioning and growth opportunities in the semiconductor test equipment market, particularly related to GPU and memory testing for AI accelerators. The topic arises mainly during the Q&A session with analysts, where management elaborates on market size, product development, competitive advantages, and quality challenges in AI accelerator manufacturing.
Gregory Stephen Smith (likely CEO or senior executive) highlights the significant opportunity in the merchant AI accelerator space, especially GPUs, which represent the majority of the compute TAM:
"So in terms of the merchant AI accelerator space, so GPUs in general, that's big. I mean it is the majority of the compute TAM. In general terms, we're probably looking at -- in -- back in 2024, there was about $2.3 billion of compute. And so making progress into merchant compute taps us into a pretty big pool. So probably in the neighborhood of 2x the size of the VIP compute out in the later parts of this -- of the term, probably more than 2x the VIP compute."
This indicates Teradyne views AI accelerators, particularly GPUs, as a large and growing market segment that could significantly expand their test equipment revenue beyond their existing VIP ASIC compute business.
Teradyne is actively developing and delivering electro-optical test solutions that incorporate silicon photonics instrumentation (via their Quantify acquisition) to address AI accelerator testing needs:
"Teradyne is already delivering an electro-optical test solution. Right now and over the next 24 months, that solution is going to incorporate more and more of the quantify photonics instrumentation. And we expect that, that part of the market is going to grow, and we expect that, that having a superior solution in that space will allow us to grow share in the AI accelerator space, both merchant and VIP."
The company emphasizes that their success in penetrating the AI accelerator market depends on product differentiation, particularly in throughput, reliability, and time to market:
"Now that we've been invited to the dance, now it is our -- like our level of success is going to be dictated by the differentiation of our product offering. And that is -- we believe that we have advantages in throughput, in reliability and in time to market."
This suggests Teradyne is confident in its technology edge but acknowledges the need to prove it to customers to gain market share.
Teradyne discusses a specific quality challenge related to High Bandwidth Memory (HBM) stacks used in AI accelerators. Yield fallout due to defective HBM stacks after assembly is a significant issue:
"What is happening is that after those AI accelerators have been assembled, they're actually seeing significant yield fallout due to HBM problems. And so what they're trying to do is they're trying to decrease the number of defective HBM stacks that get installed in these accelerators."
Teradyne is addressing this by enabling an additional test step post-dicing of HBM stacks to catch faults earlier, improving overall yield and quality:
"The thought is if you do a test step after you cut that HBM stack die wafer into individual HBM stacks, you're going to be able to catch a set of faults that you didn't see before."
This highlights Teradyne’s role in advancing test methodologies critical to AI accelerator manufacturing quality and reliability.
While the transcript does not provide explicit revenue guidance tied solely to AI accelerators, the discussion implies that AI accelerator testing is a key growth driver for Teradyne’s semiconductor test segment. The company is investing in manufacturing capabilities and product innovation to capture this expanding market:
"We expect that, that having a superior solution in that space will allow us to grow share in the AI accelerator space, both merchant and VIP."
"There are some expenses that we're taking in 2025, mostly associated with establishing manufacturing in the U.S. ... as our robotics volumes increase, since we are internally manufacturing most of robotics, we will be able to absorb our fixed costs associated with operations as our volumes go up, and we would expect to see that absorption having a positive effect on gross margins."
Although robotics is a separate segment, the manufacturing investment and operational leverage mentioned may also support AI accelerator test equipment production.
Teradyne views the AI accelerator market—especially GPUs and associated memory stacks—as a large and growing opportunity that could significantly expand their semiconductor test equipment TAM. The company is actively developing advanced electro-optical test solutions incorporating silicon photonics to address this market, leveraging recent acquisitions and internal innovation.
Success in this space depends on proving product differentiation in throughput, reliability, and time to market. Teradyne is also addressing critical quality challenges in AI accelerator manufacturing, such as yield fallout from defective HBM stacks, by enabling new test insertion points.
Overall, AI accelerators represent a strategic growth area for Teradyne, with management signaling confidence in their technology and market positioning while acknowledging the competitive and execution challenges ahead.
"So in terms of the merchant AI accelerator space, so GPUs in general, that's big. I mean it is the majority of the compute TAM."
"Teradyne is already delivering an electro-optical test solution... having a superior solution in that space will allow us to grow share in the AI accelerator space, both merchant and VIP."
"Now that we've been invited to the dance, now it is our -- like our level of success is going to be dictated by the differentiation of our product offering."
"What is happening is that after those AI accelerators have been assembled, they're actually seeing significant yield fallout due to HBM problems."
"The thought is if you do a test step after you cut that HBM stack die wafer into individual HBM stacks, you're going to be able to catch a set of faults that you didn't see before."
This analysis reflects Teradyne’s strategic focus on AI accelerator test equipment as a key growth driver and highlights the company’s efforts to innovate and differentiate in this competitive and technically demanding market.
