I'm not actually enormously fussed about per-core temperature monitoring. It was nice when I was into overclocking in a big way, but now I'm more interested in systems being stable for months at a time. My 3900X system is fairly well behaved, but the odd kernel regression does hit it occasionally - one landed yesterday; my wireless mouse now won't work through the KVM switch USB port unless I replug it after I'm at a desktop. Works fine with previous kernel version.

Terascale
GCN 1.0
GCN 1.1
GCN 1.2
Buyer beware.
The 200 series was a right mess.

Intel for sure doesn't work 100% either. Intel's reputation is better but there's no good reason for that.
There have been various fatal hardware issues in the last decade that required Intel to replace hardware (both CPUs and chipsets). Intel had to deactivate various features after the fact due to brokenness (e.g. TSX) as well. AMD arguably had less hardware issues, even though they had well-known problems with Phenom and reliability issues with some early Ryzen CPUs.
I personally experienced and to some degree still experience the following problems:
- Intel WiFi driver/firmware issues with AX200 (firmware crashes, I have to reboot to fix it)
- Bluetooth issues with AX200 as well (random HCI errors and device disconnects)
- Frequency scaling and power usage regressions on older hardware
- RC6 power management issues plagued the GPU drivers for a LONG time (a year or so?)
- Panel self-refresh (PSR) is semi-broken on my XPS 13 (and I've reported these and assisted to fix... TWICE!)

I am the first one to admit that AMD sucks at timely integrating new hardware support into the kernel, but Intel has got their fair share of duds too.

The difference between Intel and AMD has historically been that AMD generally has been problematic and not some specific SKU's. For example their sensor code i nthe Kernel has generally been terrible for all of the fairly recent lines of AMD CPU's all the way up until Zen3 (apparently).
I mean this is not surprising, Intel is much larger and hence has a much bigger engineering team specifically for Linux support. As stated before AMD is only solving these issues recently.
