  • The Compute 100: Austin Lyons, Analyst & Writer, Chipstrat

    October 06, 2026 · 📺 The Compute 100

    Today's guest is Austin Lyons, the writer behind Chipstrat. Austin started his career as an engineer — graduate work in electrical engineering at the University of Illinois under semiconductor physicist Eric Pop, followed by time at Intel. From there, he made the shift to analysis and writing, building Chipstrat into one of the most widely-read independent newsletters covering semiconductors, optics, networking, and physical AI. Austin is one of those rare people who can actually read the silicon and explain the market. When people want to know what is really happening in the compute stack, A…

  • Every Muse User Gets 2 CPUs and 8GB in Meta's Cloud. Your Phone Already Has That

    October 01, 2026 · 📺 Semi Doped

    The push to run AI agents on edge devices will not be driven by model labs or hardware vendors, but by service providers like Meta whose ad-based business models create a powerful financial incentive to offload massive cloud compute costs onto the user's own powerful-but-idle hardware. Austin Lyons and Vik Sekar break down why the failed "AI PC" push has given way to a new, economically-driven strategy for on-device AI. They discuss how Qualcomm's acquisition of Modular provides the key software layer and why the ultimate vision is an "ecosystem of you" where the device acts as a context-aware…

  • Qualcomm's Durga Malladi: HBC vs HBM, Dragonfly AI 250, and Winning on TCO

    September 24, 2026 · 📺 Semi Doped

    Qualcomm re-entered the data center inference market late — competitive GPUs, XPUs, and custom accelerators are already out there. Durga Malladi (EVP/GM, Technology Planning, Edge & Data Center) explains why they didn't build another me-too accelerator and instead placed a differentiating technical bet: High Bandwidth Compute (HBC). The difference between HBC and HBM: HBM is stacked DRAM that shuttles data across wide buses to a separate accelerator — very high bandwidth, but expensive and power-hungry. HBC bonds stacked DRAM directly on top of a custom logic die using wafer-on-wafer techniqu…

  • Pacing AI Means More Compute, Not Less

    September 18, 2026 · 📺 Semi Doped

    The debate over "pacing" AI for safety is a red herring, since more safety work doesn't slow things down; it increases demand for compute hardware. Austin Lyons and Vik Sekar unpack Dario Amodei's call to slow down frontier AI development, arguing that the true governors on AI are not voluntary agreements but physical data center bottlenecks and geopolitical realities. They conclude that the push for more safety and interpretability will ultimately drive more sales of both training (GPUs) and inference (XPUs) hardware. Today's sponsor is G2i — expert training data, evals, and RL environments…

  • TSMC Will Buy High NA After All: ASML's New 6x12-Inch Mask

    September 14, 2026 · 📺 Semi Doped

    The emergence of user-friendly AI agents is creating massive new hardware demand, which in turn is forcing the semiconductor industry into a complex, multi-year transition to High NA EUV lithography and an entirely new 12-inch photomask standard. Austin Lyons and Vik Sekar unpack the physics and economics of ASML's move to High NA, explaining why it necessitates a shift from 6-inch to 6x12-inch masks and what this means for the timelines of TSMC, Intel, and Samsung. "This is where you have to get the whole supply chain coordinated around this. And this is why you really ultimately need ASML's…

  • OpenAI’s Jalapeño! Feeling Hot Hot Hot!

    August 28, 2026 · 📺 Semi Doped

    Austin and Vik react to OpenAI's Jalapeño announcement at Hot Chips. Plus extra spicy questions like should OpenAI sell it, how much of this was AI-written RTL, and where is Anthropic's chip? Key Takeaways: The chip's core design philosophy is "dark silicon is cheaper than idle accelerators" — using one balanced chip and power-gating unused blocks is more efficient than a two-chip (e.g. GPU + LPU) solution. The unprecedented nine-month RTL-to-tapeout cycle was enabled by AI for EDA tools, serving as a wake-up call that small, expert teams can now develop Rubin-class chips in under a year.…

Notable quotes

“On the semiconductor side the biggest constraint, of course besides memory, is substrates. Substrates, PCB materials, substrate materials, all of these components were severely underinvested in. Much of the supply chains that create the materials in Japan, those firms are sort of a lot more conservative and unwilling to invest heavily in capacity. And so we've seen tremendous bottlenecks there in terms of what can be”

“In any buildout over the last few decades, we've always had the industry double order, triple order, and too much capacity get built out and supply chains are really bad at forecasting demand. This is a bit of self-moderation especially on the finance side. If we go back a year or two ago any cloud that wanted capital could pay a pretty high interest rate but they could get it. Now if you don't have really high-grade”

“The problem with these technologies is that they don't run at the speed of copper, which means to say 200 gigs per lane runs within a single rack today even bidirectionally. These technologies don't do that. So you you know microLEDs could probably run at 50 gig and microLEDs run at maybe 3 gig, you know. So they're much slower. So what you have to do is you have to convert the 200 gigs per lane that's coming out of ”

“The whole stir-up happened on the conference show floor where everybody's like, 'Oh, did you catch that talk by Bill Brennan?' And I was like, 'Oh, wait. I was watching the stuff over here.' But luckily, you know, the YouTube videos helped. I watched it immediately as soon as it was posted. So the whole thing was, the background is that for the longest time we've been thinking that microLEDs are going to be the way t”

“So, packaging used to be a fairly boring space and sort of like low value, low margin in that uh obviously if you like go way back in time, packaging was literally like taking discrete transistors and kind of like wiring to them together and then it was like taking discrete chips on a board and like printed circuit boards, you know, and just like big trace copper traces in between them. But nowadays we've moved into ”

“So, although there's like all the CPU deployments on the cloud and everybody's excited about the prospect of CPU, I'm like look, my phone is already my portal to the AI world. It's happening right now. It keeps buzzing about all the scheduled tasks I have. You're putting up stuff for sale. Everybody's happy. Things are getting done. You're making money. But then what's my CPU doing here? Nothing. So I'm like why don'”
