You are correct. In fact these guys measured a maximum socket power consumption of 240 watt using a 9950X at stock settings, running prime95. So far above the "170 watt" TDP: https://hwbusters.com/cpu/amd-ryzen-9-9950x-cpu-review-perfo...
I don’t understand this argument. If the CPU dissipated an equal number of watts of heat energy as it consumed from the wall, there wouldn’t be any energy left to do actual useful work. Isn’t the extra 100W accounted for by things like changing the state of flip-flops? In other words, mustn’t one consider the entropy reduction of the system as an energy sink?
What happens to the energy that did the useful work?
It was some time around then. I remember AMD being late to it vs Intel.
That was SpeedStep? By the time AMD got to it it was just sort of expected and didn't have a fancy name, as far as I know. Or maybe I'm thinking of something else entirely…
All you really need to see is the picture of the CPU with thermal paste only on one half. Thermal throttling is tuned to work when there is 1. a sufficient heatsink (theirs was significantly below requirements) and 2. it is installed correctly so that its triggers for downclocking happen with the correct timing. This is just another instance of ridiculous PEBCAK error
This is per design. On AM5 processors, there's a hotspot on the lower half of the processor where the dies that contain the CPU cores are located. Noctua recommends that AM5 users mount their coolers shifted towards the lower side of the processor for optimal cooling performance, see https://noctua.at/en/offset-am5-mounting-technical-backgroun... . You may have missed the paragraph in the article that explicitly poin…
Noctua recommends mounting their cooler so that the center is shifted toward the lower part of the CPU. From your picture with the thermal paste, it’s clear that your cooler is only making contact with about two-thirds of the CPU, meaning you mounted it incorrectly. The cooler’s contact area must always cover the entire CPU; otherwise, you reduce heat transfer capacity. On top of that, you’re already using an undersized cooler for this CPU. I think you don’t understand the basics of thermodynamics.
When I worked at Linden Lab we had a deal going with IBM. Either as part of that deal or in an attempt to impress our larger partner, many of us got Thinkpads. I actually kind of like them, since the cost wasn't coming out of my budget. Inside Linden, about 90% of meetings were held in-world, so we constantly had the Second Life viewer up. About three months later our Thinkpads started failing. Apparently they though…
Delaminating the PCB is absolutely wild. I'm really fascinated by the idea of doing meetings in Second Life, though. What did people use for avatars at work?
As there is ongoing drama with Zen 5 and power issues, there are people with the instruments and the motivation to investigate this. You should consider contacting Gamers Nexus, and help them to get your test suite running. They can measure power draw and do a thermal analysis of this CPU, and they'd likely be eager to do it, given the possibility of making a bunch of dramatic YouTube content about design flaws in wi…
They don't say what temperature the CPU was reporting which seems like an odd omission. Whatever the specs of your cooler etc check the temperature it's actually running at. Go by what the CPU is saying! I've got the older 3950x, and the first one died after a few months (still in warranty) with a cooler in spec, but it would go into the 90s at full load just doing big builds. I replaced the heatsink with a basic wat…
A modern CPU should be able to detect temperature excursions and bring itself to a safe halt even if you power it up without any cooler attached. It's normal and expected that people making mistakes around the cooling systems of their CPUs will accidentally give themselves terrible performance. It is not normal that the CPUs will break.

The small coolers used by them are not recommended by Noctua for 9950X. Noctua recommends only bigger coolers for 9950X, which dissipates 200 W permanently on a workload like theirs (which is much less than the over 250 W dissipated in similar conditions by the competing Intel CPUs). Despite this, the overtemperature protection of the CPUs should have protected the CPUs and prevent any kind of damage like this. Besid…
> The small coolers used by them are not recommended by Noctua for 9950X
Noctua's CPU compatibility page lists the NH-U9s as "medium turbo/overclocking headroom" for the 9950X [0]. I don't think it's fair to suggest their cooler choice is the problem here.

AMD has failed to be reliable with its Zen 4 and Zen 5 consumer CPUs, just at the same time Intel did the same with their 13k and 14k higher end CPUs. AMD is somewhat worse than Intel as their DDR5 memory bus is very "twitchy" making it hard to get the highest DDR5 timings, especially with multiple DIMMs per channel.
What do you mean? Is your second sentence the only reason for the first?

Clearly paste was squeezed out from the entire perimeter of the CPU. Offset mounting is used intentionally for this CPU. Probably there's less paste remaining on the south end of the CPU because that's where the mounting force is greatest. If anything, there's too much paste remaining on the center/north end of the CPU. Paste exists simply to bridge the roughness of the two metal surfaces, too much paste is a bad sig…
Many reviewers have tested that too much paste is not an issue, except being messy to clean.
Given that Gamers Nexus needs the ad revenue wouldn't linking to a re-upload that wouldn't give them any of that be sort of bad?
While they can't publish it themselves this at least achieves the goal of the information being spread, along with the knowledge that it was their investigative team that did the work in the first place. But yes, once they reedit and republish themselves (or manage some sort of appeal and republish as-is) then of course linking to that (and a smaller cut of the parts they've had to change because Bloomberg were litig…
It sounds like their lawyers have done the appropriate counter-challenge with YouTube, so the video will go back up unless Bloomberg sues them in the next so many days. And this is Gamers Nexus, so I presume they will fight to keep it as is on principle.
Personally, I found the length of the quotes from politicians kind of tedious, but I sure wouldn’t want them to capitulate to Bloomberg after this.
