I like the Apollo3 in the Sparkfun Artemis module, but yowza, take a look at its new big brother the Apollo4:
  • 2M of MRAM (I think that means it is magnetoresistive non-volatile RAM instead of flash for program storage)
  • 1.8M of SRAM
  • Cortex M4 with floating point running at 96 MHz or 192 MHz processor clock
  • USB interface
  • Bluetooth LE
  • MIPI Display Driver
  • Crypto engine
  • 3uA/MHz]
More details here: https://ambiq.com/apollo4/

Hey Sparkfun, any plans for an Artemis Module based on the Apollo4?

If the apollo4 clocking mechanisms are like the apollo3, it means that the apollo4 at 96 MHz will draw the same power as an apollo3 at 48 MHz. It would be amazing!

I can't help myself: long ago (early-ish 1990's), I worked at HP Labs. At one point, I got a brand new HP PA-RISC workstation. It ran at 99 MHz, and it was unbelievably fast compared to the PCs of the day. The new Apollo4 is roughly as capable a processor, and running at 96 MHz, it will be drawing about the same amount of current as the 'power on' indicator LED on that old workstation. Where will we be in another 25 years...
