I can't comment on the quality question, but for memory bandwidth sensitive use cases, Intel desktop is superior.
I'm not convinced, what would be the use case?

So you're saying that if you go even 3 degrees Celsius over that temperature range you should expect your CPU to fry itself? Even when the CPU throttled itself to exactly 100°C?

#63I have not had any issues with Intel or AMD CPUs but I have so many issues with AMD APUs, I would steer clear of them. In my experience with different models, they have many graphics issues, broken video transcoding and overall extremely unstable. If you need decent integrated graphics then Intel is the only real option.
My laptop's AMD is great (Ryzen AI 7 PRO 360 w/ Radeon 880M). Gaming, GPI work, battery, small LLMs - all just work on my Ubuntu.
Don't know about transcoding though.

#64No desktop CPU I’ve ever used has remained stable at 100 degrees. My 14900k crashes almost immediately at that temp. 3 hours at 100 degrees is obscene.
Then all your desktop CPUs were defective.
Besides AMD CPUs of the early 2000s going up in smokes without working cooling, they all throttle before they become temporarily or permanently unstable. Otherwise they are bad.
I've never had a desktop part fail due to max temperatures, but I don't think I've owned one that advertises nor allows itself to reach or remain at 100c or higher.
If someone sells a CPU that's specified to work at 100 or 110 degrees and it doesn't then it's either defective or fraudulent, no excuses.

#65I realize this has not much to do with CPU choice per se, but I'm still gonna leave this recommendation here for people who like to build PCs to get stuff done with :) Since I've been able to afford it and the market has had them available, I've been buying desktop systems with proper ECC support.
I've been chasing flimsy but very annoying stability problems (some, of course, due to overclocking during my younger years, when it still had a tangible payoff) enough times on systems I had built that taking this one BIG potential cause out of the equation is worth the few dozens of extra bucks I have to spend on ECC-capable gear many times over.
Trying to validate an ECC-less platform's stability is surprisingly hard, because memtest and friends just aren't very reliably detecting more subtle problems. PRIME95, y-cruncher and linpack (in increasing order of effectiveness) are better than specialzied memory testing software in my experience, but they are not perfect, either.
Most AMD CPUs (but not their APUs with potent iGPUs - there, you will have to buy the "PRO" variants) these days have full support for ECC UDIMMs. If your mainboard vendor also plays ball - annoyingly, only a minority of them enables ECC support in their firmware, so always check for that before buying! - there's not much that can prevent you from having that stability enhancement and reassuring peace of mind.

It is actually 2.9999, precisely.

#67Seems like failure in choosing cooling solutions. These high-end chips have obscene cooling needs. My guess would be using something that was not designed for TDP in question.
Sufficient cooler, with sufficient airflow is always needed.

In my experience with different models, they have many graphics issues, broken video transcoding and overall extremely unstable. If you need decent integrated graphics then Intel is the only real option.
I've had the same experience with an 8600G on Linux. Very frequent graphics driver crashes and KDE/Wayland freezes, on old and new kernels alike. I've been submitting error reports for months, and the issues still persist. The RAM passes MemTest, and the system otherwise works fine, but the graphics issues are very annoying. It's not like I'm gaming or doing anything intensive either; it happens during plain desktop usage.
Yet I also use a 7840U in a gaming handheld running Windows, and haven't had any issues there at all. So I think this is related to AMD Linux drivers and/or Wayland. In contrast, my old laptop with an NVIDIA GPU and Xorg has given me zero issues for about a decade now.
So I've decided to just avoid AMD on Linux on my next machine. Intel's upcoming Panther Lake and Nova Lake CPUs seem promising, and their integrated graphics have consistently been improving. I don't think AMD's dominance will continue for much longer.

#69Earlier quoted context omitted.
Also be careful with overclocking, because the usual advice of "just running EXPO/XMP" often results in motherboards setting voltages on very sensitive components to more than 30% over their stock values, and this is somehow considered normal. It looks completely bonkers to me. I overclocked my system to ~95% of what it is able to do with almost default voltages, using bumps of 1-3% over stock, which (AFAIK) is withi…
Since you mention EXPO/XMP, which are about RAM overclocking: RAM has the least trouble with overvoltage. Raising some of the various CPU voltages is a problem, which RAM overclocking may also do.
The heat is starting to become an issue for DDR5 with higher voltage.
