Apple‘s hardware diagnostic test tool is built into Macs. Four Apple Silicon Max, there’s a new procedure to activate it.
Apple Diagnostics, formerly known as Apple Hardware Test, can check your Mac for hardware issues.

I haven’t used it in a long time, and when I have in the past I often got false negatives. I remember one time I was running it on a Mac, the GPU was failing and it could clearly be seen by all the artifacts on the display, but somehow it passed Apple‘s diagnostic test.
Even the Apple stores in-house diagnostic test that is used by the geniuses often gives false negatives. I posted my experience on the forum with a failing HDD in a fusion drive. It was clearly signs of a failing drive, but the Apple store refused to replace it under the AppleCare warranty because it kept passing their hardware test.
They would wipe the drive, reinstall the software, only for me to take home my Mac and have the problem come back a few days later. I would take it back to the Apple store, rinse and repeat for months.
Eventually, 12 days before my warranty was over, the drive fully failed, and failed hard. The failure screwed up the boot loader on the iMac so that it wouldn’t boot into recovery, not an external boot drive, or even their own diagnostic tool. They finally replaced it under the warranty.
12.6 , planning upgrade to Ventura. You think Ventura should improve speed ?
P.S. Read up on issues with some of my software and decided to wait until 13.1
Personally, I would wait before updating to Ventura, at least until there’s a stable release.
Then again, it sounds like you’re already having some issues, so maybe it might be worth trying some thing like installing Ventura.
In addition to apples hardware diagnostic test tool, you can try some other third-party software.
You can try geek bench, and compare your MacBook Pro‘s score against Watson the Mac listings.
Black magic disk speed test is pretty popular, but it only does sequential tests.
I like this other software to task disk speed, but I can’t recall the name right now. I will have to check one of my Macs and post it on here.
I think there is a memory stress test app on the Mac App Store for free. Again I cannot remember the name of it, but I think that’s where I got it from.
