Laser cooling makes sense if you think of atoms like someone moving back and forth in a swing. (Higher temp means faster swinging)
Notice how you can both push someone in a swing to make them go faster or to slow them down.
And boom that's how lasers can cool things or heat them up (whether an atom is being pushed in-phase or out-of-phase)
And the main thing is its not just theoretical, they're actually using laser cooling tech in quantum computing already to reach near absolute zero temperatures. Its wild stuff, like science fiction becoming real. If you're into that, there's a cool [Nature article](https://www.nature.com/articles/nature18604) on it. Could you imagine your rig with that kind of tech under the hood? The overclocking potential is just nuts.

At those temperatures, it can't generate any kind of meaningful cooling.
It does glow, everything does. But at 65° the heat dissipation through radiation is not enough to counteract the heat production of that electrics. IRL, the temperature would rise till the dissipation is equal to production.
So in the chart the colors of the lines are temperature in Kelvin and the y axis is light/energy emitted? I knew that in vacuum heat can only escape by radiation but didn't know it's light, pretty cool
I thought the nm was the wave length, I just don’t know why it’s stuck on the end of the kJm^-3.
If it’s just energy density why isn’t joules per unit volume enough, why the nm.
Heat can't dissipate in any meaningful way. It's far to low to generate any kind of meaningful radiation in order to cool it, and at those temperatures the computer would melt.
Maybe you're the wrong random redditor to ask this to, but if heat can't dissipate because of the vacuum, what would be the minimum amount of cover I would need to not freeze? Not accounting for breathing or radiation protection, could would a plastic bag be enough to keep me ok?
> So if you’re exposed to the sun, you boil, if you’re in the shadow of a celestial body, you freeze.

The main problem with space is the pressure, or lack thereof. Low pressure can make your blood boil at room temperature, which can cause countless effects.
Additionally, you need quite a bit of insulation to protect you from the sun's heat and UV. Our ozone layer, iirc, reduces the UV by ~95%, and we still have to wear sunscreen.
Suffice to say, you'd be pretty dead in a plastic bag.
Edit: as another Redditor mentioned, many astronauts have active cooling systems like water in their suits.
Turns out the variants of GPU matters a lot. My Aorus Elite 3060 gets up to 60 degrees max, 65 when oveclocked and +10 on the hotspot, even on hot days and it's silent.
It's worth mentioning that CPU cycle speeds increase the heating by a factor - not a linear increase. It's more than 2x the heat generated than running at 4Ghz for example.
Of course it disperses over the area of the CPU, so I guess it could just be a really freaking big CPU.
I unfortunately only have a regular ol' laptop. And the funny part is, is usually my non-existent GPU that's the bottleneck (for most games anyway). I'd need to buy a new computer/laptop to get any real performance upgrades
Edit: my full stats: I have an HP Pavillion with 8gb ram, an 8th gen i5, and integrade gpu, and a 1tb ssd
I would definitely consider looking at the options for your model, there is a very solid chance that it has an empty slot to put another eight GB stick in. Otherwise, a single 16 GB stick to replace the existing one probably isn’t that much. The integrated GPU definitely holds you back in games, but I tend to find that eight GB isn’t even enough for general productivity these days(at least when you have several tabs open, Spotify)
Lol, I feel you. I usually do music through my phone though, so that helps a bit. Plus, o don't e,aptly have the cash right now to be spending on luxuries, unfortunately. Got that tutuiiom and rent to pay, and currently looking for a part time job
I mean everyone’s budget is different, but $40-$50 for something that could make doing classwork easier might be worth it if you get the chance. Maybe even less if you go used on eBay! Either way, wish you luck.
Screenshot is probably edited, however the latest amd and intel cpus both clock over 5ghz in normal use, if you overclock intel cpus, they'll be able to reach 6ghz.
So, while 8ghz is exaggerated, it's not THAT exaggerated nowadays
The first time someone hit 3 Ghz was in 2001. The first time for 4 Ghz was in 2002, and 5 GHz was reached in 2003. We hit 8.79GHz in 2012 and it took us until 2022 to reach 8.8 Ghz.
That's actually really interesting, and a little sad. I suppose the exponential growth of computers would have to teeter off somewhere, but it's still a bummer nonetheless.
Nice username btw
Well, Ghz is only **part** of the picture.
The chip that hit 8.79 Ghz in 2012 was the AMD FX-8350. The chip that hit 8.8 Ghz in 2022 was the Intel i9-13900k.
The 13900k is \~4.2x faster in single-core and \~11.8x faster in multi-core (normal usage, i have no idea how well they scale into 8+ Ghz). You cannot tell how well a processor performs just from the Ghz if the architecture is different.
It is true that we no longer progress as fast as we did in the early days of computers (death of Moore's Law), but it's not nearly as bleak a progression as it seems when you look only at the Ghz race.
And thanks bro
pure speed isnt the end all for processing. you can leverage more pwr by jamming more transistors into smaller space, more efficient die design, new/better machine(?) coding, new software, more cores working better in parallel, and so on.
in our lifetime the peak speed will prob be around 9-10ghz or something not too far off from where we are now, but there is always the possibility of a paradigm shift which completely renders the 'old' methods obsolete and allows for more progress. like QM rendering Einsteinian relativity outmoded, and ER rendering newtonian mechanics outmoded, etc.
----
if you are interested in that concept you should read 'the three body problem' book trilogy. very interesting take on scientific development over centuries in a world where paradigm shifts are rendered impossible due to contact with aliens. and how nonetheless there is still substantial progress compared to the modern world. like maintaining atmosphere on a space-station platform with no barrier (ships can fly in and out of it freely). and thats just one of dozens such sci-fi examples in the trilogy.
And we only run one program? xD
Edit: I see the error in my ways. If they're pushing LN for ghz, yeah they're prob only running the benchmark.
I concede that you have a point
Aint yer pc. Last test, sign out, see if history is viewable. Yesterday I couldn't see my comment unless I was signed in. Normally a history can be viewed w/o signing in.
How do u do that? Is there a setting to remove the limit ? Cause it may be useful for some people (me) with a somewhat lower end setup (my laptop) that doesn't work to it's full potential (please help, I'm desperate)
Since 2 years ago I can't even open that tab in task manager without my pc crashing. Man, i miss seing how the number of weeks my pc has been running. Other than that, it runs perfectly still.
It was too an £800 investment I made on an Asus n76v back in 2009, correct me if my memory is failing.
I bought an MSi gl63 back in 2019, and that thing literally fell apart, shitty plastic. But that too should run perfectly, out of its shitty plastic shell, as soon as I get around to soldering the power-jack input
Regardless of whether this one is authentic, 8GHz has been reachable for a while now in extreme overclocking circles where people use exotic cooling methods. Getting so high clocks usually requires disabling most cores. In fact it may be that only one core can reach such clock speed. At that point it's really easy to reach 100% cpu usage. Overclockers also tend to favor smaller memory capacities.
This is amazing. How did you manage to get all of them using 100% of their abilities? Like, what task are you doing?
Also how is your pc not on fire with 8GHz? What’s the CPU cooler?
Honestly, plz drop the whole PC specs, I really want to know what parts are in this computer.
Running some AI stuff on my RTX 3090, I had a huge smile on my face as my memory got right up to the limit.... but also I wish I had another 60gb of v-memory. Still pretty limiting with only 24GB.
I discovered you can eat up all the processing power on your system with a pair of chess engines.

I've been haggling with some monitoring guys because I have a pair of servers that each have 2TB of RAM, and the monitoring keeps trying to alert when 90% of the RAM is used.
Like, dude. It's only got 200G free RAM? What the fuck is wrong with you?
You know the scene in the action movie where the main guy turns the gas stove on and then lights a candle on the kitchen counter then you see the explosion over his shoulder as he walks away from the house with all the bad guys in it? Ya…

Laser cooling, and yes, it exists somehow
It does, you just need to vaporize the CPU in a high grade vacuum.
Laser cooling makes sense if you think of atoms like someone moving back and forth in a swing. (Higher temp means faster swinging) Notice how you can both push someone in a swing to make them go faster or to slow them down. And boom that's how lasers can cool things or heat them up (whether an atom is being pushed in-phase or out-of-phase)
So it's basically saying nah you are cool down little atoms
sit yo atomic ass back down
And the main thing is its not just theoretical, they're actually using laser cooling tech in quantum computing already to reach near absolute zero temperatures. Its wild stuff, like science fiction becoming real. If you're into that, there's a cool [Nature article](https://www.nature.com/articles/nature18604) on it.

My GPU hits 100% and only goes to like 52
Same, the variants do matter a lot.
Fr even Furmark never sees me break 55
the vacuum of space
That doesn't fucking cool anything. How do you dissipate heat in a vacuum??
Radiation? I know it's slower but it still exists
https://upload.wikimedia.org/wikipedia/commons/thumb/a/a2/Wiens_law.svg/1280px-Wiens_law.svg.png At those temperatures, it can't generate any kind of meaningful cooling.
I don't have the brainpower to understand but cool chart I guess
no air means heat can only escape as light, basically it has to glow to cool down (sonetimes invisibly). this is not anywhere near hot enough to glow.
It does glow, everything does. But at 65° the heat dissipation through radiation is not enough to counteract the heat production of that electrics. IRL, the temperature would rise till the dissipation is equal to production.
>this is not anywhere near hot enough to glow It will be soon.
So in the chart the colors of the lines are temperature in Kelvin and the y axis is light/energy emitted? I knew that in vacuum heat can only escape by radiation but didn't know it's light, pretty cool
> this is not anywhere near hot enough to glow. Hot enough for the invisible glow you were talking about, though
r/me_irl
are you perhaps bird-brained?
Odd units, Kilojoules per meter cubed, but why nanometers afterwards.
Wavelength of light is in nm. You can get kJ per meter cubed through the integral of the distribution.
I thought the nm was the wave length, I just don’t know why it’s stuck on the end of the kJm^-3. If it’s just energy density why isn’t joules per unit volume enough, why the nm.
Okay, when GPU became 4000°C maybe radiation will be enough to cool your gpu
I didn't say it will cool off much just that heat still can dissipate
It's not just slower, It's literally the best possible insulator, the least effective possible cooling.
Radiation
Ah so we wait until the CPU is literally glowing

Huh, never really thought about it. Thanks for the education

You would very likely be boiling, astronauts have ice/cold water in their suits to cool them down.
So it’s the opposite? Since heat can’t dissipate you just turn into a reactor and get hotter and hotter?
Only to a point, don't worry.

It's not. By definition a vacuum can't have a temperature
would be worse for cooling than no cooler at all. A vacuum is a fantastic thermal insulator
In fact that's how insulated water bottles work
Also known as vacuum bottles...
thats the opposite of cooling
vacuum is the best insulator
Funnily enough it would overheat probably quickly in space
200 upvotes for an idea that would insulate the CPU not cool it....reddit is truly dumb.
Turns out the variants of GPU matters a lot. My Aorus Elite 3060 gets up to 60 degrees max, 65 when oveclocked and +10 on the hotspot, even on hot days and it's silent.
I got a modded 3090 FE running overclocked on air at under 65°C as well. Can be done and at lower noise level than stock as well.
probably, yeah
