What a freshly fabbed $300 AMD CPU gets you

Across each Zen CPU complexes are 20 thermal diodes, 48 power supply
monitors, nine voltage droop detectors, and more than 1,300 critical
path monitors. An Infinity Fabric control plane monitors these
readings 1,000 times a second, and are accurate to 1mA, 1mV, 1mW, and
1°C.

A machine intelligence unit's algorithms adapts to provide core
voltages based on loading and temperature.

Software provisions power management operatives, usually provided by
motherboard BIOS tweak utilities, will operate at an hundredth's-more
factor of course granularity, to an operational speed of Ryzen's
on-chip capacity;-- in later singularity the terminology is called a
PO power state.

....Notably for Ryzen chips capable of overclocking, as with mating
motherboard chipsets so enabled. Interesting in that selecting that
preference, enabling overclocking -- all those fancy and new AMD power
schemes, obviously not some inconsiderable feat, get basically shot to
hell. Along with a standard disclaimer issuance, that your Ryzen may
prematurely fail, melt into oblivion, due to a zealous regard for
speed.

Correction:
Coarse Granularity, a MB/BIOS software utility, in conjunction to an
OS factor and layer of what the BIOS has additionally to offer by way
of user options specified by AMD Ryzen.

will lm_sensors be able to tell you how warm it is running?

Sure...I'd think. (I'm a Speedfan-ner, unique to going back
conceivably to 386s and Winderz95. For the most a relatively
functional setup, juggling about chipset selections for fewer entire
updated revisions, or eventually popping in an approximate chipset to
admissible readings.)

lm_sensors (Linux-monitoring sensors), is a free open source
software-tool for Linux that provides tools and drivers for monitoring
temperatures, voltage, humidity, and fans. It can also detect chassis
intrusions.
https://en.wikipedia.org/wiki/Lm_sensors

Provided support and necessary updates, if required for a socket AMD4
setup, to polling relevant MB port addresses.

HWMonitor is the parent identity to LM-Sensors...

As stated on their site, "most common sensor chips." Ryzen is
already pretty common: it's getting some serious premier showtime
paired to Intel: whambam, and Intel dropped $100 straight across their
flagship chips almost to the day AMD opened the sluices for Ryzen.

Since it is part of an internal hardware management plane,
there is no guarantee any of that will be exported for
your usage.

Things like that are only guaranteed to be visible if they're
addressable on a hardware bus. And the CPU doesn't need for
those to be visible, as they're under some kind of internal control.

A practical motherboard will have the usual SuperI/O with hardware
monitor, and the usual number of sensors (3 temp, 3 fan, 9 voltage
if you're lucky). The CPU can still present the anode and cathode
of a single thermal diode, for usage by a SuperI/O hardware
circuit. Lm_sensors will use the SuperI/O, like always.

I called a few local PC shops, and they are out of the top-shelf 1800x CPU.
(online sellers are claiming to have it in stock)
So that's what is in demand. I wonder if anybody will be rushing out for
the mid-range Ryzen 5 next month.....

I looked at the pricing here, and I'll have
to wait for the dual core one, before I could
afford it.

Three out of four MB models for a Ryzen are presently also out of
stock (of 17 MB capable of running a Ryzen). The 5 series is already
being sold over an illegal world market, ie not as AMD endorsed for
scheduled release.
