iMac 2020, 5700XT - graphical glitch?

[Sheza]

As soon as you turn on the computer the chipsets get some heat, again, the heatsink iMac is using is more than not enough to hold the heat of those chipsets.

Maybe they replaced humans for monkeys in their research labs to go higher on benefits, I do not know.

In all of your posts, you seem to say that it doesn’t even matter if there is any load on the system - that even at idle it is overheating. If that were true, people running benchmarks or playing intensive games or doing video rendering would surely have a melted computer by now?

not all chipsets go out of the fabric having the same quality even when all of them are the same model

chipsets makers had made huge improvements last years to do not let their chipsets burn (years ago that literally happened), that does not mean those are bulletproof and/or can stand any conditions

yes, I do expect problems in all iMacs sooner or later

Мой imac 2020, i9, 5700xt, ram 8gb тоже имел те же проблемы с белой линией с нагрузкой и без нагрузки. Я поставил масштабирование на максимальное (5К) и вернул обратно по умолчанию. После этого работал 3 часа пока никаких белых линий на экране не было. Кто много и долго работает с компьютером попробуйте сделать то же самое. Будут ли появляться линии?

Been using my new iMac for a week, been seeing the white line glitches about a dozen times per day, finally called up Apple and they want me to bring the computer in and let the technicians take a look... which I doubt they’ll find anything. Debating if I should just return the computer and buy it again when this issue is resolved...

other than this glitch issue, I’m really lovin this machine though. Came from a 15” MacBook Pro with a broken graphic card.

Are you happy going back to a 15” MacBook Pro with a broken graphic card? If so, return the machine.

I came from a working 15” MacBook Pro and I would not be willing to go back so I am keeping mine.

I do not want to offend anyone Sheza, thermal sensors could had been tweaked

I insist, those are desktop chipsets. Any heatsink vendor would tell you it is crazy to place those in a non proper dissipated case as it is iMac case.

I'm using Mac myself, not iMac 2020 you are right, and is a legit Apple product what I have at home.

Do you mean the only solution is to rethink the whole inner concept of the machine will this machine have a decent lifetime ? ? this makes me even more anxious to order this iMac !

or release a new iMac using Tiger Lake instead, GPU benchmarks show as much power as PS4

thats enough for an iMac

for someone needing more, they could use a eGPU

or Mac Pro (small form factor)

or Mac Pro XL

I do not see how they are gonna replace an entire generation of faulty iMacs

My last iMac was still going 10 years after I bought it. My 2014 15" MacBook (which sounds like a hair dryer anytime I ask it do do something demanding) has been working flawlessly for the last 6 years.

This suggestion that these 2020 iMacs will melt down is absurd.

and my Mac Mini 2014 still working perfect, just is not enough powerful for some tasks

is not absurd

Absurd is what they are doing nowadays, not releasing Mac Pro small factor, releasing iMac with bad architecture

it seems they are so occupied on their iPhones, iWatch, iPads and they left the Mac computers aside

and apple laptops are gonna become kind of iPads as soon as they switch to ARM


Is their own fault.

It looks like they are not taking seriously the costumers that want a Mac as desktop computer.



Laptops still being good nowadays.

Desktops just overpriced and with wrong architecture.

I already wrote the reasons to state that:
Mac Pro is too big, they just dropped the itx architecture they were using in last Mac Pro.
iMacs they just tried to fit too much power in a case that cannot hold it.

I absolutely agree. I have been running my new iMac at high load for two weeks as the hub of my audio recording studio. I have experienced no overheating issues. The fans run relatively low speed except when the processor or GPU loads are maxing out the machine. Last night I ran the United Heaven benchmark at the ultra settings and my GPU temperature ramped up to 97 degrees (the GPU maxed out) and then the fans ramped up and the temps lowered to 87 degrees and stayed there throughout the rest of the testing. These new iMacs are not going to “burn-up” and any concerns that they will is not realistic.

Wish I was home to install.
Someone let us know if it works.

I am at home but the update unsurprisingly requires a reboot. I won't be doing that during regular business hours. I do see the same message about the 5700XT. Let's hope it works.

 

[CL14715]

Glad its supposedly fixed but now I’d be interested to know what caused it.

 

[shywizard]

Installed 10.15.7 a few minutes ago.
So far, no glitch! But it's only been 3 minutes.

I kinda feel bad we were so tough on Apple. Clearly, they were working on a fix behind the scenes. Shame on all of us for doubting them.

STATUS UPDATE:
22 minutes on 10.15.7 and no white horizontal line glitch. Yippy.
But corner glitch still exists (which to be honest I didn't care about).

From the Apple Insider comments:

"A graphics glitch that I did find is that I've been playing "Shadow of the Tomb Raider" and the cloud/smoke effects behave like lightning/strobe-lights. My 2015 iMac does not do this. I'm not reading into it yet and it may be completely unrelated but I'm looking forward to seeing what this OS patch does."

This is me. I've seen only one line glitch in the three weeks I've had my iMac, but the Shadow of the Tomb Raider issue was a thing. A really annoying thing. I'm hoping this will be fixed as well. Stay tuned.

Is this the MacOS version of Shadow of The Tomb Raider? Just wondering if it's that one or the Windows version in Bootcamp.

Mac OS version. Started the Windows 10 Bootcamp version the other day, but so far no issue and I cranked the graphic settings to Ultra.

Okay cool. I'm gonna probably grab it on Bootcamp then.

Got mine from Steam and you can load both for the single price.

AMD released updated boot camp drivers on 09/08. You’ll have to go to AMD’s site to grab them.

I still blame them, they ruined 0.7 seconds of my iMac experience

Does this fix the square corners?
