It has to be 3x faster to match M1's efficiency given the TDP is 30 vs 105.
- Thaxll 5y agoI could care less about efficiency, it's still 2x faster for 2/3x less expensive. Isn't the m1 max tdp between 60 and 90w?
- glasshead969 5y agoIts 60-90w including GPU.
- arcticbull 5y agoWell yes but ones a laptop chip with a 17 hour life and the other I’ve got under my desk heating my entire condo lol
- interstice 5y agoIf you could conceivably run a chip at a much higher TDP before hitting thermal limits you could get significantly more performance. Not that you can (probably) OC these chips at all but it suggests there may be more rabbits in the bag.
- jbverschoor 5y agoYou're comparing a single CPU with a complete machine
- speed_spread 5y agoIf you're plugged in all the time, lower TDP is nice but not critical. And if you live in a cold country, you have to heat up the house six months per year, TDP is just heating with a computing side effect.
- new_realist 5y agoA hot laptop can have significant impacts on fertility in men. And in the summer you have to dissipate that heat. A heat pump is more efficient for heating, to boot.
- uuddlrlr 5y agoIt's a temporary infertility, at least.
- TYPE_FASTER 5y agoThis winter I'm going to experiment with having a Raspberry Pi act as a thermostat that starts/stops containers running on a server in our basement. That, combined with the laptop we just got for gaming that has a 3070 in it, should do nicely to supplement our heating system.
- Uehreka 5y agoWatts go in, Watts come out. So basically, find a space heater with the TDP of your server, and that’s the upper bound on what you can expect heating-wise. I know that’s a bummer for people who want to heat their house with their computer, but Thermodynamics is always a bummer, I don’t make the Laws.
- buildbot 5y agoThat's why I heat my house with a dell C4140! The _lowest_ power throttle it has is 1.4KW.
- matheusmoreira 5y ago> So basically, find a space heater with the TDP of your server, and that’s the upper bound on what you can expect heating-wise. I wonder how many CPUs I need to build a cryptocurrency miner water heater... That would be so much better than just wasting energy heating up dumb elements.
- bparrish0 5y agoModern heat pumps provide a lot more than 100% efficiency. I'd stick to the heating system unless those containers are doing something profitable (mining?)
- chris37879 5y agoLiterally nothing provides 100% efficiency. You're conflating coefficient of performance with efficiency. They're not even close to the same thing, modern heat pumps reach their CoP because they don't actually generate heat, they simply move it around, which provides more heat indoors than if you had converted an equivalent amount of electricity directly into 100% heat. Thermodynamics would not take kindly to you having a >99.999...% efficient anything.
- girvo 5y agoAs someone who lives in south-east Queensland, Australia, lower TDPs and thermal output is always welcome, at least for me. I adore my Ryzen 5600X/3060 Ti mini-ITX desktop, but mining on it makes my room annoyingly warm, and it's not even summer yet. Was semi-useful in winter though, all 6 weeks of it...
- coldtea 5y ago>If you're plugged in all the time, lower TDP is nice but not critical. "If you're plugged in all the time" then try the Mac Pro version when it comes out. This is about performance in laptop models, where it IS critical.
- yxhuvud 5y ago> And if you live in a cold country, you have to heat up the house six months per year, TDP is just heating with a computing side effect. Except it is still direct electrical heating which is atrociously inefficient.
- ClumsyPilot 5y agoIt's 100 efficient, and the amount of houses with a heat pump is <1%
- yxhuvud 5y agoHere in Sweden, roughly 50% of all small houses (ie one household) have a heat pump. Direct electricity heating is just somewhere around 15%. In bigger houses direct electricity just isn't a thing, most have some sort of central heating, and lots have either some combustion or heat pump solution. The latter is gaining.
- authorityofnil 5y ago>Except it is still direct electrical heating which is atrociously inefficient. Electric heating converts practically all energy into heat, making it ~100% efficient. You can make statements about cost-effectiveness compared to burning things, but not all houses can. CHP configurations are more common in colder climates with district heating, so their "waste" heat during generation often isn't wasted at all.
- new_realist 5y agoBut a heat pump is more than 100% efficient.
