Sorry for my ignorance but i read that as "We will never switch to arm because arm is better". Maybe i need an ELI5?

Blowing out dust isn't that much of a problem if you can open the laptop with ease. But that is a big if.

> Are you saying Peltier coolers remove heat by generating electricity?

No, I said the opposite. That by pumping electricity into them they remove heat.

I've already been corrected in that I got mixed up with something else., but no, not that

I used the fans to destroy the fans

I think it sounds like a cool in-vent-ion.

They have little fans on them

You can't compare power usage of a x86 core and an ARM because one was designed for high performance, and the other was designed for low power consumption. It's also why every cell phone uses an ARM processor.

It's like comparing the fuel economy of a Ford 350 and a Prius. Sure, if all you want to do is drive around town, the Prius will get you there just as fast, and it'll do it for 1/3 the gas.

Maybe it’s naive to think this aloud, but I recently got a glimpse of what a small, simplistic view of what the metaverse could be when I recently bought the Quest 2. I played the Rec Room game for about 15 minutes and all I heard was a bunch of kids running around calling each other racial slurs and saying awful things to anyone they crossed. I’m not convinced the adult version is going to be a whole lot better.

Like this LTT video?

You don’t exist. Just a bunch of tangled atoms!

Zuck, nobody wants the metaverse. Nobody

Just more marketing spin IMHO.

cool

Cold doesn't exist. Just a lack of thermal energy!

You’re the guy who created the silicon chip at Apple lurking on Reddit, aren’t you?

Are you saying Peltier coolers remove heat by generating electricity? Because they absolutely can if you apply a temperature difference across them, but to force the heat to move they actually have to convert some electricity into heat in the process.

That's the difference between thermoelectric coolers and thermoelectric generators, one uses electrical energy to move heat and the other turns the movement of heat into electrical energy.

Yes, the problem is getting to that point. You might have a few, very expensive laptops that are early adopters, but I see it being an uphill battle to get them the capital to build out the facilities necessary to produce these in large enough quantities to precipitate affordability.

Pretty sure it only cost like that because of very low supply and low demand. Over time the cost will go down if they mass manufacture it.

I can't imagine that this kind of cooling solution would be anywhere near cost effective.

Didn't LTT do a video on a hand sized one that cost over $1k? Imagine trying to miniaturize that and the associated cost increase.

Peltier coolers have been a thing in missiles since the 70s. They aren't particularly efficient but they're lightweight.

My guess is it's just the way the companies have headed due to their main products.

Apple mainly deals in their phones and tablets while still making some computers on the side so naturally they'd want to invest more into their mobile platforms where cooling is passive. Thermal and power efficiency is the primary focus while trying to bump up speed at the same time.

Intel on the other hand deals with systems that have cooling systems. Servers and desktop coolers get pretty beefy so can handle a lot. Raw performance wins and thermals are slightly less important. Sure they have CPU's for laptops and NUCs which lack good cooling but those tend to get lower specced CPU's.

I built my new PC last week and saw that the trend in CPU's has done a 180. My first PC was from 2013 and buying an unlocked CPU to overclock for better performance was the norm. Power pull and thermals be damned.

These days the unlocked CPU's boost themselves to a pre set limit but pull big power and generate heaps of heat. Now some people undervolt to try keep thermals under control without sacrificing too much performance.

Personally, I'm blown away by it

Gonna have to suck up my downvotes.

> Sounds like a violation of the first law of thermodynamics. Some heat must be dumped somewhere.

No. I thought of that too, but that comes from the generation/transmission of electricity.

Also I had it mixed up with peltier coolers
