Virginia Report Finds Groundwater Running Dry for New Data Centers
No locations east of I-95 can support major new groundwater withdrawals under current Virginia permitting standards, officials say.
A Virginia study concludes that no location in the US Coastal Plain east of Interstate 95 can support major new groundwater withdrawals under the state's permitting standards. The finding matters because this region contains the world's largest concentration of data centers, which are water-intensive facilities that have traditionally supplemented municipal water supplies with on-site groundwater wells. The report tested whether a hypothetical industrial facility withdrawing three million gallons of groundwater per day could qualify for a permit and found that maximum sustainable withdrawals in areas near the Interstate 95 corridor were below 30,000 gallons per day, forcing data center operators to rely more heavily on municipal water systems. Groundwater levels peaked around 2021 and are now expected to decline within five to 10 years under current conditions, with population growth and rising chloride concentrations adding further pressure to the region's constrained water resources.

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 […]
