Ferroelectric Helps Break Transistor Limits

news.ycombinator.com Katherine Bourzac 2025-12-11 15:39:50

Integrating an electronic material that exhibits a strange property called negative capacitance can help high-power gallium nitride transistors break through a performance barrier, say scientists in California. Research published in Science suggests that negative capacitance helps sidestep a physical limit that typically enforces trade-offs between how well a transistor performs in the “on” state versus how well it does in the “off” state. The researchers behind the project say this shows that n

Unreal Engine ray tracing stuttering in AMD RDNA 4 GPUs linked to Nvidia-optimized game code

What just happened? Ray tracing was supposed to be faster and smoother on AMD's latest GPUs, yet some demanding games still struggle. A closer look now points to the real reason behind the disappointing performance. It's not just hardware limitations at play – engine choices and driver quirks are also shaping the experience.

In 2002, artificial intelligence was still in winter. Despite decades of effort, dreams of bestowing computers with humanlike cognition and real-world understanding had not materialized. To look for a way forward, a small group of scientists gathered for “The St. Thomas Common Sense Symposium.” AI pioneer Marvin Minsky was the central presence, along with his protégé Pushpinder Singh.

“Don’t cannibalize the audience” is an unwritten mantra in Hollywood. If a movie that is coming out has a similar subject matter or serves a similar viewership as one you are releasing, you try and put some distance between them so as not to ruin your chances of success.
