Please learn to read. Again. I thought I wasn’t on Reddit anymore.
$50 for a pi. Not for clustering. For one. That’s it.
An X86 PC is gonna cost you hundreds. That’s how I can cluster rpi, for the same cost. I hope you now know how to do basic math.
This isn’t even true. A Pi sells for 50$ yes, + USB cable for power + USB power adapter + case + whatever else money grab.
A second hand HP mini with an i5 7th gen CPU that is WAY faster comes with everything including 8 GB of RAM and 256GB of SSD (or better if you get a good deal) for around 80$. Tell me about your math again…
How’s the power consumption compare between two performance equivalent setups? (Genuine question, it’s something I’m trying to determine for my self-host use-cases).
My first RPi is for Joplin to replace OneNote. My current server runs 24/7 and costs about $1/day for power (it provides other services too). I haven’t calculated my Pi power consumption yet, but it’s running on a 2.5 watt power supply, vs my server 700 watt (of course, these are both peak measurements).
Given my self-host stuff will spend 99% of its time at idle, it seems like Pi has a massive advantage. But of course that all depends on how things are used and setup.
The raspberry pi, like all RISC chips, uses much less power.
In fact the super computer summit runs on powerpc64 which is a RISC chip, that’s a big reason why its power consumption for a super computer is so low.
I hadn’t considered the RISC angle. Does RISC consistently use less power than CISC at given operations levels (MFLOPS, for example), or is there another/better way to make a power-consumption vs operations/performance comparison?
I realize this is kind of esoteric for my use-cases, but it would be useful for making projections to see if spending X dollars on Y number of Pi’s recoups the investment over a given period, just in power consumption.
E.G. If I can reduce my power consumption by 70% by switching to 3 Rpis, then I can recoup their cost in 2-3 years. Since my server needs replacing anyway, this seems like a no-brainer.
Yeah, a second hand old as shit hp, that’ll die on you so quick. There’s a reason that hp is selling for so cheap. HP is garbage, unless you’re buying their actual servers…

Not my experience. At all.
Edit: also all the “cash grab” parts… you probably already have those parts just lying around doing nothing.
Yes I sure have a proprietary adapter for their PCIe connector lying around. Even with the power adapter, the RPI is picky and will require a decent thing that is usually more than your average smartphone.
This is self hosting… You’re telling me you or one of your friends don’t have a printer to print a case for less than a dollar? Shit, pay for shipping and I’ll send you a case.
PC for 1/10 of the performance and reliability.
That’s not my experience at all. I mean the other user already posted a PC you can buy for the same price as a pi. It’s about as good as a 4, the 5 is 3x that speed.
See the problem now?

Insulting my reading ability and math skills would work better if you weren’t making a fool of yourself.
I gave you an example of a $50 x86 PC and mentioned the more expensive options because you brought up building a pi cluster in your first response to me, at which point you’re not talking about spending $50 anymore.
The main point is that either the thin client or the slightly more expensive computer will runs circles around your pi(s) for the same price.

No you didn’t. You gave an example of a >= 200 x86 PC… So, like… That’s why I even suggested clustering. To match the cost of your claim.

Maybe you should worry more about your own math skills than mine.

Oh, so like… A worthless fucking machine… Sure. You use that. Let me know how many minutes that lasts.
