Your Phone's Next Speed Boost May Come From Magnetic Chips (phys.org) 29
alternative_right writes: A new technology has been proposed that could fundamentally solve the issue of smartphones overheating during high-spec gaming or extended video streaming. Researchers at KAIST have discovered the principle of processing signals using the minute vibrations of magnets (spin waves) instead of electrons. This method significantly reduces heat generation and power consumption while enabling instantaneous frequency switching within the several GHz range. This breakthrough is expected to pave the way for smart devices with less heat and longer battery life, as well as ultra-low-power, high-speed computing. Professor Kab-Jin Kim from the Department of Physics said: "This study is a case that proves we can implement and control the nonlinear dynamics of magnons -- the principle of information processing using magnetic vibrations -- in actual nano-devices, which had previously only been proposed in theory. It will serve as an important foundation for the development of a new information processing paradigm using spin waves instead of electrons."
The findings have been published in the journal Nature Communications.

Theoretically possible, but both memristor and magnon technology needs to advance a lot.
I remain surprised we haven't seen memristors outside the lab yet - invented in 1971, the first working ones created around 2008. You'd think we'd have at least transistor replacements by now (small clusters of memristors can be combined to make smaller, more efficient transistors).
Magnonics, though... they're decades more recent and the basics are still being worked out.

Just as all phones are standardizing on using electromagnetic fields for charging. I can already picture it: a dongle you put in your car's wireless charging compartment, with a wire running out plugged into your phone that's bouncing around your floor.

Yes, this may eventually go into production. No, it will not be the "next" thing or the one after it. While very few of these discoveries make it, those that do take 20 years, 30 years or longer to get there.

The computer architecture we use for AI given what it does and how much of it is probabilistic is really dumb and wasteful, spintronics is one candidate to speed it up if a few problems are solved.

Any performance uplift of RAM applies equally to any use of RAM. AI isn't special here.

It is actually pretty deep with AI. Long ago here I was writing about how memory that minimizes erasure should use less energy than flash memory with its erase cycles, and that is what MRAM does. Spin changes only consume energy with bit change instead of full erase voltage discharge. (Landauerâ(TM)s principle) If you look a brain architecture (20 watts) vs AI simulations (200,000 watts to do similar) on difference is the brain maximizes non erasure. Thoughts are combinatorics selections that fire oth

There are no materials that attenuate magnetic fields in the way that we can with shields and electric fields, you can only attenuate magnetic fields and they travel through any material. Because of this it's likely that any computer with magnetic computing would suffer from interference.
