Put another way: if AMD (and especially Intel) don't do something about this they're going to get completely eaten alive by ARM.

The amount of processing power available in a modern smartphone is truly mind-boggling. I'd love to see a chart showing the chip cost and energy cost of the power on an M1 chip in each previou syear. I would guess that 30+ years ago you'd be in the millions of dollars and watts of power but that's just a guess.

As we see from the modern M1/M2 Macbooks, these lower TDP SoCs are more than capable of running a computer for most people for most things. The need for an Intel or AMD CPU is shrinking. It's still there and very real but the waters are rising.

When I was an undergrad, one of my professors was exploring “approximate” computation (forget what it was technically called). The gist was that you build mathematical circuitry that approximates an answer instead of giving you a concrete answer (kinda like floating point but also applied to Boolean algebra, integer math etc). The reasoning was that the approximation could let you reduce the power. I wonder where tha…

"Fuzzy logic" was the "AI" hype buzzword of the 90s.

What if all the text in your comment was approximately the correct set of letters in each word?

As long as the first and last are good you can kinda figure it out

In my own experience, the supposed ARM chip superiority claims are almost entirely marketing. I get significantly better performance (15-50%) from nearly all of my CPU workloads on modern Intel/AMD hardware vs the ARM Apple devices.

For many things, like neural networks, it's probably good enough.

nVidia's DLSS works somewhat like that: the game engine generates a low-res/noisy/low framerate image, and the GPU refines it with an ML model.
