As an almost exclusively microcontroller user of Arm's products, a big meh from me. v8 is still slowly rolling out. M33 is making headway but I was really hoping for M55 to be the bigger driver.

That folks are still making new Cortex-A7 (2011) designs is wild. A-35 doesn't seem to be very popular or better.

Cortex-M33 (2016) derives–as you allude to–from ARMv8 (2015). But yeah it barely seems only barely popular, even now.

Having witnessed some of the 9p's & aughts computing, I never in a million years would have guessed microcontrollers & power efficient small chips would see so little change across a decade of time!!

It's because the software ecosystem around them is so incredibly lousy and painful.

Once you get something embedded to work, you never want to touch it again if you can avoid it.

I was really, really, really hoping that the RISC-V folks were going to do better. Alas, the RISC-V ecosystem seems doomed to be repeating the same levels of idiocy.

Switching microcontrollers means you have a lot of work to do to redo the HW design, re-run all of your pre-production testing, update mfg/QA with new processes and tests, possibly rewrite some of your application.. and you need to price in a new part to your BOM, figure out a secure supply for some number of years... And that just assumes you don't want to do even more work to take advantage of the new chip's capabilities by rewriting even more of your code. All while your original CPU probably still does fine because this is embedded we're talking about and your product already does what it needs to do.

You can get a lot of mileage out of a Cortex-M7. NXP has some which run up to 1 GHz - that's a ridiculous amount of power for a "microcontroller". It'd easily outperform an early-to-mid-2000s desktop PC.

Isn’t there some dynamic at play where STM will put one of these on a board, that board becomes a “standard” and then it’s cloned by other manufacturers, lowering cost? (legality aside)

STM32H5 in 2023 (M33): https://newsroom.st.com/media-center/press-item.html/p4519.h...

GD32F5 in 2024: https://www.gigadevice.com/about/news-and-event/news/gigadev...

STM32N6 in 2025 (M55): https://blog.st.com/stm32n6/

i.e. it takes some time for new chips to hit cost targets, and most applications don’t need the latest chips?

I don’t know a lot about the market, though, and interested to learn more

Same. On v7 still for most things, even on newer MCUs. The v8 ones, for the use cases I've encountered, primarily add IOT features like secured Flash.

This is nothing about ARMv9 the ISA but much more about their new CEO Rene Haas. Arm has always been pricing their design on the lower end, bundling GPU and other designs IP. I have long argued since they enter 64bit era their performance profile and profits does not align well especially when comparing to AMD and Intel.

Even with the increased pricing the Cortex X5 / X925 and upcoming X6 / X930 they are still pretty good value. Unless Apple has something big with A19 / M5 the X6 / X930 should be competitive with M4 already. I just wish they spend a little more money on R&D for the GPU IP side of things.

Hoepfully we have some more news from Nvidia in Computex 2025

Before reading article: I would like to know if this architecture will help Linux close to Apple architecture efficiencies....

After reading article: I suddenly realize that CPUs will probably no longer pursue making "traditional computing" any faster/efficient. Instead, everything will be focused on AI processing. There are absolutely no market/hype forces that will prompt the investment in "traditional" computing optimization anymore.

I mean, yeah, there's probably three years of planning and execution inertia, but any push to close the gap with Apple by ARM / AMD / Intel is probably dead, and Apple will probably stop innovating the M series.

apple M4 vs Intel Core Ultra 9 285K. apple m4 vs AMD Ryzen AI 9 365

apple has to do something.

im not sure intel cpus can have 196GB ram, or it is some mobile ram manufacturing limit, but i really want to have atleast 96GB in notebook, tablet.

M4 still has >2x better performance per watt than either of those chips. Of course they are pretty much ignoring desktop so they can’t really compete with AMD/Intel when power is not an issue but that’s not exactly new

You think so? I posit that the deliverance of AI/ML (LLM/genAI) services and experiences are predicated upon "traditional computing" - so, there will be some level of improvement in this domain for at least quite some time longer.
