As the title reads, my GPU is spiking from 0-100% for no reason...

Why?

Acivity Monitor is showing CPU...

It appears GPU is 0% in your screenshot.

what is this interface...can not account for third party software(?)

Is there an issue?

you have 16 cores x 100% so your "spike of "100%" is barely idling...

in Activity Monitor you can add %GPU if you think it worth it...

Control click in the column header area and make some changes to suit your needs...

Thanks for the replies...

You can see on the bottom of the screenshot how the graph looks. Sadly when I took the screenshot it was at 0%.

that is why I posted that as the Activity Monitor does not show the GPU graph automatically, so I have this tool to monitor it (Stats).

This happens from time to time and I don't have anything GPU heavy running, other than what you can see in the Activity Monitor.

The symptoms manifest in heat mostly and some lagging when moving windows and browsing. So I cannot do any heavier work if I don't reboot. That is also how I spotted this as everything I did was kinda slow.

As this is my first M based Mac (been using them since G3 era) this is new to me as I always had a discreet GPU in them...

Look, I know how it is unified and all, there are still separate cores between CPU and GPU so even though they share memory and other stuff, they don't do each other's workload.

The only thing I see in the Activity Monitor is Notification Center takes most of the GPU time and I've seen it take up to 60% of GPU, but nothing when spiking.

Next time it happens I will check the logs, maybe I can see more then and post it here...

—A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies

Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled temporarily.

Login and test. Reboot  as normal and test.  Caches get rebuilt automatically.

This test will tell you if third party interference; most extensions etc are not loaded in safe boot mode.

—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support

 This will tell you if it a universal issue or isolated to your user/admin account.

unplug all non-essential  peripherals when testing

Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

all known to cause issues on the macOS

if you had an issue you would suspect to be pegged in the RED.

not seeing it in your screen shot above(?)

for comparison ref:

Your M-series Apple SoC — has unified memory, allowing the GPU and CPU to share memory without penalty;

some operations lend themselves to the CPU, others are ideal for the GPU.

Is this interfering with user-perceived operation of your computer in some substantial way?

If so, please describe your overall symptoms.
