How To Test 208 Billion Transistors

Nvidia’s Blackwell Ultra has 208 billion transistors across 2 dies. Those dies are made in a titanic fab. Using an intricate process with hundreds of steps, dealing in the dozens of nanometers. So dumb question: How do we know it all worked? How can we be sure that the thing being made actually does its job and not be “the other guy”? This is why the multi-billion dollar Automated Test Equipment or ATE industry exists. In today’s video, an underrated part of the semiconductor ecosystem. ---------------------------------------- Get all episodes of Asianometry, Sharp Tech, Sharp China, Stratechery Updates and Interviews, Greatest of All Talk, and Dithering as part of Stratechery Plus [https://stratechery.passport.online/member/plan/4ycW4SE71Cy6ryrijywbTG] for $15/month or $150/year. ---------------------------------------- Listen to Stratechery [https://open.spotify.com/show/1jRACH7L8EQCYKc5uW7aPk].

Gas Turbine Blades and their Heat-Defying Single-Crystal Superalloys

A gas turbine’s high pressure rotor takes on some of the most extreme temperatures in industry. And must do it for 100,000 operating hours. Right now, we are booked out of gas turbines for the rest of the decade. The shortage got me thinking about fan blades. Today, modern gas turbine inlet temperatures can reach an infernal 1,600 degrees Celsius. That’s hotter than most lavas. What can handle such extreme conditions? Some of the most special metals you will ever see in your life. Metals tortured to survive things that regular metals never can. And it is still not enough. In today’s video, my friends, we study the blade. And the materials that make them. ---------------------------------------- Get all episodes of Asianometry, Sharp Tech, Sharp China, Stratechery Updates and Interviews, Greatest of All Talk, and Dithering as part of Stratechery Plus [https://stratechery.passport.online/member/plan/4ycW4SE71Cy6ryrijywbTG] for $15/month or $150/year. ---------------------------------------- Listen to Stratechery [https://open.spotify.com/show/1jRACH7L8EQCYKc5uW7aPk].

VLIW: The “Impossible” Computer

You are walking down an alleyway late one night, and suddenly behind you, a mysterious dark figure appears and says. Sir, I promise you a computer. A computer up to 20 times faster than what is on the market. You think. Well, what sort of unholy, insane 2-nanometer silicon will this computer be using? No, the dark figure replies. Ordinary hardware. Same as what everyone else is using. Maybe even a bit slower, clock time-wise. So what is the catch? If you accept this computer, then you must also accept some of the most brilliant but maniacal compiler software ever created. Oh. In today’s video, we trace a radical idea to a computer 10-30 times faster than anything thought possible. They said it was impossible. An intrepid platoon of geniuses proved them wrong. ---------------------------------------- Get all episodes of Asianometry, Sharp Tech, Sharp China, Stratechery Updates and Interviews, Greatest of All Talk, and Dithering as part of Stratechery Plus [https://stratechery.passport.online/member/plan/4ycW4SE71Cy6ryrijywbTG] for $15/month or $150/year. ---------------------------------------- Listen to Stratechery [https://open.spotify.com/show/1jRACH7L8EQCYKc5uW7aPk].

The Supercritical CO2 Turbine: Waterless Wonder

For over a hundred years, steam turbines have generated power using water and steam. Over the years, that steam got hotter and more pressurized. It made the turbines more efficient, but also made them big and complicated. Now here comes a different type of turbine. Radically smaller. Drastically simpler. These turbines have CO2 running through their veins instead of steam. In today’s video, supercritical carbon dioxide turbines. The waterless wonder that may be 10 times smaller than their counterparts. ---------------------------------------- Get all episodes of Asianometry, Sharp Tech, Sharp China, Stratechery Updates and Interviews, Greatest of All Talk, and Dithering as part of Stratechery Plus [https://stratechery.passport.online/member/plan/4ycW4SE71Cy6ryrijywbTG] for $15/month or $150/year. ---------------------------------------- Listen to Stratechery [https://open.spotify.com/show/1jRACH7L8EQCYKc5uW7aPk].

Singapore’s Sound Card Hero

It used to be that if you wanted to get good audio on your computer, you had to get a sound card. And if you needed a sound card, there was just one choice: Sound Blaster. The company behind this iconic brand, Creative Labs or Technology, actually came from the city of the Merlion: Singapore. Their fortunes rose and fell with that of their most iconic product. In today’s video, a look at Singapore’s sound card tech hero. ---------------------------------------- Get all episodes of Asianometry, Sharp Tech, Sharp China, Stratechery Updates and Interviews, Greatest of All Talk, and Dithering as part of Stratechery Plus [https://stratechery.passport.online/member/plan/4ycW4SE71Cy6ryrijywbTG] for $15/month or $150/year. ---------------------------------------- Listen to Stratechery [https://open.spotify.com/show/1jRACH7L8EQCYKc5uW7aPk].
