Nvidia wants to make your Windows PC an agentic and creator powerhouse
Why it matters: Nvidia just announced what it calls the most efficient PC chip ever built. RTX Spark is a Grace Blackwell system on a chip, 70 billion transistors on TSMC 3nm, with a Blackwell RTX GPU, a 20-core Arm CPU built with MediaTek, and up to 128GB of unified memory. It is purpose-built for agents, and it runs full RTX gaming and creation on the same thin-and-light laptop. It is a genuinely impressive piece of silicon.
University of Illinois team stacks three active silicon layers on a single chip, achieving 98-100% transistor yield
Forward-looking: For years, the chip industry has chased better performance by shrinking transistors and squeezing more of them onto a flat slice of silicon. That strategy is running into hard limits. A group at the University of Illinois thinks the next gains will come not from going smaller, but from going vertical.
The MacBook Neo already rattled the PC industry. Now imagine what Apple could do next
Crystal ball: Let's be clear upfront: there is no Mac Neo desktop. No leak, no supply chain rumor, no analyst note. What follows is conjecture – but conjecture worth taking seriously, because the pieces are sitting right there on Apple's workbench.
Highly anticipated: A team in Japan has developed a Wi-Fi receiver capable of operating in the extreme radiation inside nuclear reactors, an advance that could help robotics teams safely decommission aging power plants. The receiver, developed at the Institute of Science Tokyo, demonstrated resilience under radiation doses roughly 1,000 times higher than what typical electronics can withstand.
