Here is a great video on chip degradation if you want to know more :
Rambling about chip degradation

Both chips will be impacted by thermal cycling: the silicon die with the APU and the copper substrate below it should thermally expand at different rates. So over many heating/cooling cycles, connections between the two will be degraded. The bigger the die, the worse the effect. Temperature is a catalyst, but it's unclear if there would be much of a difference between the two here, especially if the power consumption stays constant and the temperature doesn't get very high.
Oxide breakdown is a damage over time to transistors when the voltage is too high and the impact of temperature is high. The impact of temperature is really important here. Since the chip that might run the highest voltage is the PS5 APU, it might be more impacted by oxide breakdown. Only if temperature is high, anyway. This can happen outside of loads if the temperature stays high even though current stays low.
On the other hand, the XSX APU will run lower voltage (but higher voltage for similar clocks), but consume more current, so it should be more subject to degradation through electromigration. But this can happen only during full loads, when a lot of current goes trough the chip.
Keep in mind that even though these chips are more sensitive to voltage and current, and consume more current than previous gen chips, they also consume lower amounts of power and both consoles should use sufficient cooling systems. Both chips also are not overclocked, so if they run at spec they will last their expected lifetime, unless issues we are not aware of arise.
That's why I deleted the post and I said sorry few times. Can we just stop attacking me and keep driving through the thread ? Thank you ;)
I see. Thanks for this,
I think this would be the best case scenario for the industry as a whole having consoles so close feature and performance wise, as the less work required to support both developers and consumers win alike. Devs by being able to reach more consumers with less efforts and consumers that will have more games to play.
Ah ok, I see your point now. Yeah, hard to think it was something they even considered.
Do you know if Sony already experimented with the clocking boost from the start (which would make sense if they were indeed limited to 36cus due BC) or that came over time adjusting to feedback from developers?
A bunch of halo avatars acting like corporate astroturfers has gone unmodded for a long time in playstation threads. Its pretty disappointing really.
Little late for that. I appreciate the apology, but you should have thought it through before posting, as it turned yet another PS5 thread into a shit show. Now, instead of the interesting technical details of the article this thread is about platform wars, yet again.
EDIT:
And even if some of them get banned, it's only for a day or few, after which they return to the same behavior sooner or later. Such little slaps teach nothing to people like that.
That was not my intention, I can't control what people does. I just asked about if that "technical" issues are true because I thought this thread was about PS5 tech stuff. Next time I will think twice before posting. But seriously, stop quoting me, you guys are make me feel like im worst than trash.
This thread was about the technical info in the DF article, now it is about fanboy fiction. You can control yourself, as it's obvious what that kind of posts lead to around here.
User banned (1 month): Trolling. Hostility.
Just a little notice. The concern and FUD you are seeing around PS5 news lately is being done on purpose. Some of it is planned in a certain discord.
This thread heading to the dumps is apart of it i presume. There's this sad attempt to make PS5 look like it's going to fail and experience another PS3 generation.
That is all. Bye.

Basically higher frequency doesnt make up for less CUs.
Interesting. It would be nice to know who around here and elsewhere are on the Discord channel.
Nice video by df. 👍
Yikes if thats true. It wouldn't be surprising though.Just a little notice. The concern and FUD you are seeing around PS5 news lately is being done on purpose. Some of it is planned in a certain discord.

User Banned (1 week): platform warring
Pray for them, they'll have to deal with Lockhart all the gen.
I wouldn't worry about it too much. It's not your post that started the derailment of the thread. There were already a bunch of the usual suspects concern trolling in here even before you posted.
The test case is not equivalent to the difference found in consoles.
The best thing to do is report these members, a couple with Halo avatars and others on the last few pages, and hope they receive censure as its made this community much worse over the past few weeks.
User Banned (1 week): accusations of shilling, platform warring
I remember last gen ms had shills spreading fud about ps4 and trying to downplay the drm fiasco. Would not suprise me one bit if they were at it again, i mean their top executives associate themselves with some deranged fanboys. You would not see jim ryan or hermen do the same thing again, they would run the other way.
In the past I might have taken Jez seriously, but this is just ridiculous.
I always found the last minute OC claim odd. It might look like just 230Mhz jump from 2Ghz, but those last 230Mhz are hardest to hit. There would have to be fundamental shift in design, cooling and power to get to that stable OC.
If I remember correctly (I could be wrong so please correct me if I am) the PS4 was originally going to have 4GB GDDR5 but they added in an extra 4GB last minute. This could be a similar situation.
I'm not even on discord and have been accused of being some Xbox fanboy concern troll here because.. well. I had concerns. I don't see how making wide sweeping accusations is at all helpful here; if there are trolls and you know they organize on discord call them out. Making sweeping statements like that basically just makes everyone who isn't a troll not want to engage in any conversations here.
Exactly and this is not attacking the console like this, they will sell more console. They just need to continue the good communication around Xbox Series X communication. They don't need to discredit themselves with this FUD. It all made them looking like some buffoon. Sony does a pretty good job currently to not hype the PS5...

Must be "For The Greater Good".
If it has nothing to do with you then why comment on it like you seem offended? That makes you look more suspicious.
Yeah, that's about as laughable as it gets. If nothing else, based on some of the things I've read today, it is the exact apposite (though not particularly from Microsoft, but those who wish to see their competitor fail).
Not last minute but yeah, it changed from 4GB in devkits to 8GB in retail. RAM changing from early devkits to retail is not uncommon, 360 added 256MB more memory on Epic's request, PS3 was going to be all CELL 256MB machine but later added Nvidia GPU with 256MB memory, XB1 added eSRAM (aka secret sauce) to assist with DDR3 memory etc.

Yeah I agree with this.
If there is really any proof of this happening then show it so it can be handled by the mods. Because of a few bad apples it does not mean everybody is a troll.
Because it makes me not want to comment here?
Your post being a prime example of exactly what makes me not want to talk videogames here lol
Why do people do this? Ask obvious questions as so
oh my god guys...it's video games.
You can talk about games all you want, I'm not attacking you. It just seems strange that you're defending the people that derail these threads, and they've done the same thing in plenty of past threads.

Well I am not surprised if that is the case it's been thread after thread regarding PS5 littered with concern trolling it's getting ridiculous.
I did not remotely defend any of those people. I said call them out directly because vague accusations just make everyone in the thread who wasn't 100% gung ho pro-Sony feel on edge and accused. Or report the shit to moderators maybe? It serves little purpose in a thread like this. It's not going to stop concern trolls unless you actually get moderators to do something.
The mods are too busy playing Animal Crossing.
Which is what I'm going to do now.
What self respecting journalist would post a tweet of a comment in a thread and ask if it is legit or not? You're gonna tell me right now that dude wasn't trying to start shit, really?
I have been seeing some examples of what seems like coordinated mass anti-PS5 posts in comments sections under youtube videos that praise PS5 in any way. And they all seem to follow similar phrasing and misinformation buzzwords, and each post has a ton of thumbs ups, out of proportion to any other comments. Maybe I'm just seeing things, but it does feel like some kind of trolling effort is going on.
Apparently not, as some have a need to spread FUD about a gaming system (ie. a toy) they aren't likely even getting. Let alone, continuously shit on threads they see as threats to their toy.
There's a major difference between asking questions and concern trolling. You can ask about the PS5 all you want like I did in my initial post in this thread, but the "EVERY SSD IN THE PAST THROTTLES SO THE PS5 SSD WILL TOO" garbage posts aren't needed. We don't know how the PS5 cooling system is designed until Sony releases the teardown video.
You'd think being able to boast that you have the strongest console out the gate and likely have the best third party games would be enough to sate console warriors' thirst. But that's apparently not enough. Got to enter threads on "the enemy" and pepper it with FUD, concern trolling, downplaying, fanboy drivel from Twitter or comment sections, and obtuseness.
