IBM claims world’s first sub-1 nanometer chip technology
A new chip architecture from IBM can integrate nearly 100 billion transistors on a chip the size of a human fingernail—nearly twice the transistor density of the company’s previous generation of chip technology. The resulting improvement in chip compute performance and energy efficiency comes from what IBM describes as the “world’s first sub-1 nanometer chip technology” for AI data centers. “It's not just an incremental step, it's a meaningful leap forward,” said Jay Gambetta, director of IBM Re
IBM announced a new chip architecture called "nanostack" that can fit nearly 100 billion transistors on a fingernail-sized chip, roughly doubling the transistor density of its previous generation. The technology is described as "sub-1 nanometer" because it delivers computing performance improvements expected from theoretically smaller transistors, though actual physical features cannot be built smaller than 1 nanometer due to physical limitations. The nanostack architecture vertically stacks transistors in a staggered layout and could provide up to 50 percent higher computing performance or 70 percent greater energy efficiency compared to previous chips, along with 40 percent improvement in memory scaling for AI applications. Commercial chips using this technology are expected to begin production within five to ten years and could eventually replace the current mainstream nanosheet architecture used by leading semiconductor manufacturers.

Google Unveils TPU 8i Max and TPU 8tx: A Dual-Chip TPU and a Confidential TPU
Google has added two new systems to its eighth-generation TPU lineup. TPU 8i Max targets massive context windows and rack density. TPU 8tx targets secure, confidential inference. Google TPU 8i Max is a dual-chip package built from 2 TPU 8i chips. Both arrive alongside TPU 8t and TPU 8i, announced in April. TL;DR Size: TPU 8i Max = 2 TPU 8i chips in 1 package. TPU 8tx = TPU 8t silicon plus 5th Gen AMD EPYC hosts. Runs on: Google Cloud TPU systems. Performance: 8i Max doubles TPU 8

IBM Announces IBM Quantum Nighthawk r3: A New Processor to Support 10k Quantum Operations on 520 Programmable Qubits
IBM has announced IBM Quantum Nighthawk r3, its next superconducting quantum processor. It is designed to run 10,000 quantum operations accurately across 520 programmable qubits. In 2027, IBM plans to link 2 r3 chips into a single 1,040-qubit system. For developers, the announcement is speed. The current Nighthawk r2 already runs workloads up to 19x faster than IBM’s earlier processors. TL;DR Size: Nighthawk r3: 520 programmable qubits, 2,034 physical qubits, 10 l-couplers. Nightha
Why the data center you dread might never even be built
The data center boom is running into serious real-world obstacles, from widespread local opposition and permitting delays to a scramble for electricity. Before those challenges even come into play, though, there’s a more basic problem: A lot of the projects being announced may never get built in the first place. With billions of dollars in AI infrastructure […]
