The text clearly explains all of this.

No it does not. Which part of the text do you feel explains this?

First off, there's a chart for CPU temperature at the very top and they do talk about it:

> I also double-checked if the CPU temperature of about 100 degrees celsius is too high, but no: [..] Intel specifies a maximum of 110 degrees. So, running at “only” 100 degrees for a few hours should be fine.

Secondly, the article reads:

> Tom’s Hardware recently reported that “Intel Raptor Lake crashes are increasing with rising temperatures in record European heat wave”, which prompted some folks to blame Europe’s general lack of Air Conditioning.

> But in this case, I actually did air-condition the room about half-way through the job (at about 16:00), when I noticed the room was getting hot. Here’s the temperature graph:

> [GRAPH]

> I would say that 25 to 28 degrees celsius are normal temperatures for computers.

So apparently a Tom's Hardware article connected a recent heat wave with crashing computers containing Intel CPUs. They brought that up to rule it out by presenting a graph showing reasonable room temperatures.

I hope this helps.

I feel like both Intel and AMD are not doing great in the desktop CPU stability department. I made a machine with a Ryzen 9900X a while back and it had the issue that it would freeze when idling. A few years before I had a 5950X that would regularly crash under load (luckily it was a prebuilt, so it was ultimately fixed). When you do not have a bunch of components ready to swap out it is also really hard to debug the…

>I made a machine with a Ryzen 9900X a while back and it had the issue that it would freeze when idling I also have this issue.

If you are on Linux, there are long time known problems with low power cpu states. These states can be entered by your CPU when under low/no load.

A common approach is to go into the BIOS/UEFI settings and check that c6 is disabled. To verify and/or temporarily turn c6 off, see https://github.com/r4m0n/ZenStates-Linux

that's a pretty bad decision $/perf wise I'd wager. AMD decidedly owns the desktop space, and deserves so.

wdym? https://www.cpubenchmark.net/cpu_value_alltime.html CPUs like Intel Core Ultra 7 265K are pretty close to top Ryzens

Intel CPUs are decidedly better value when multicore performance is a concern. At the top end they trade blows.

If your workload is pointer-chasing intel's new CPUs aren't great though, and the X3D chips are possibly a good pick (if the workload fits in cache) which is why they get a lot of hype from reviewers who benchmark games and judge the score 90% based on that performance.

> I also double-checked if the CPU temperature of about 100 degrees celsius is too high, but no: this Tom’s Hardware article shows even higher temperatures, and Intel specifies a maximum of 110 degrees. So, running at “only” 100 degrees for a few hours should be fine. I'd say that even crashing at max temperatures is still completely unreasonable! You should be able to run at 100C or whatever the max temperature is f…

Just FYI Google runs their data centers at 85 degrees F (about 30 degrees C). I think Google probably knows more about how to run Intel CPUs for longest life and lowest cost per CPU cycle. After all they are the #5 computer maker on earth. What Intel is doing and what they are recommending is the act of a desperate corporation incapable of designing energy-efficient CPUs, incapable of progressing their performance in…

Google runs datacenters hot because it's probably cheaper than over-cooling them with AC.

Chips are happy to run at high temperatures, that's not an issue. It's just a tradeoff of expense and performance.

M3 ultra is the more capable chip by quite a bit. For instance: 80 GPU cores versus 10 in the m4.

Twice the memory bandwidth, twice the CPU core count... It's really wacky how they've decided to name things

For what it's worth, I have an i9-13900K paired with the largest air cooler available at the time (a be quiet! Dark Rock 5 IIRC), and it's incapable of sufficiently cooling that CPU. The 13900k draws more than 200W initially and thermal throttles after a minute at most, even in an air conditioned room. I don't think that thermal problems should be pushed to end user to this degree.

The "Dark Rock 5" marketing materials say it provides a 210 W TDP [1] and marketers seldom under-sell their products' capabilities. So if your CPU is drawing "more than 200W" you're pretty much at the limits of your cooler. [1] https://www.bequiet.com/en/cpucooler/5110

Feels like CPU manufacturers should be at least slapping a big warning on if they're selling a CPU that draws more power than any available cooler can dissipate.

I 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 yea…

Isn't it mostly an ease of mind thing? I've never seen a ECC error on my home server which has plenty of memory in use and runs longer than my desktop. Maybe it's more common with higher clocked, near the limit, desktop PC's. Also: DDR5 has some false ecc marketing due to the memory standard having an error correction scheme build in. Don't fall for it.

I pick up old serves for my garage system. With edac it is a dream to isolate the fault and be instantly aware. It also lets you determine the severity of the issue. Dimms can run for years with just the one error or overnight explode into streams of corrections. I keep spares so it’s fairly easy to isolate any faults. It’s just how do you want to spend your time?

You have to go pretty far down the rabbit hole to make sure you’ve actually got ECC with [LP]DDR5

Some vendors use hamming codes with “holes” in them, and you need the CPU to also run ECC (or at least error detection) between ram and the cache hierarchy.

Those things are optional in the spec, because we can’t have nice things.

I run a handful of servers and I have a couple that pop ECC errors every year or three, so YMMV.

It's crazy how unreliable CPUs have become in the last 5 years or so, both AMD and Intel. And it seems they're all running at their limit from the factory, whereas 10-20 years ago they usually had ample headroom for overclocking.

The 7800X3D is amazing here, runs extremely cool and stable, you can push it far above its defaults and it still won’t get to 80C even with air cooling. Mine was running between 60-70 under load with PBO set to high. Unfortunately it seems its successor is not that great :/

Same for 9800X3D here, which is basically the same CPU. Watercooled. Silent. Stupidly fast.
