384 threads is fucking bizarre!

I would like to see the fans needed to cool this in a 2U or even 1U case. They must be comparable to a leaf blower…

I mean you can dissipate all the heat of a 2kW electric space heater with a single fan. 500W isnt that much compared to GPU farms with a bunch of gpus in a single rack slot.

Considering that any server with one of these is likely to have two of them, that’s quite a lot of heat to dissipate.

A cpu also generally needs to be kept cooler than a space heater.

My home server has a row of surprisingly powerful and small fans and that’s just for a few years old dual Xeon system. I have never personally been (knowing) near a GPU farm but I have been behind a crazy ass router (Cisco ASR 9000 something) that’s like 10+ U. The airflow behind the router is crazy.

difference is temperature, it’s easier to cool things when there is a large temperature difference

Pretty much every modern server is a space heater with accidental compute.

What about older servers? Aren’t those even less efficient?

2.6 Watt per core, that’s pretty efficient. My desktop PC’s CPU uses twice as much.

Does it also have a base clock of 2250 MHz?

Base clock means nothing these days, every cpu in existence (even server parts!) will boost to something higher and downclock to 800MHz

No, but considering how rarely I use the full power of my CPU, I doubt it would make a big difference. Which means that I could probably halve the TDP of my CPU, but “about the same efficiency as my throttled desktop CPU” is still pretty alright for a server.

x86 was a mistake

Divide the tdp by the number of cores. You’re getting 2,6 watts per core, making it an extremely efficient cpu.

While that is true, it definitely can’t compete with ARM, even when that ARM CPU is on a 5nm node:

And if you think 192 cores is a lot, Ampere has also announced a 512 core CPU.

I got a 1000w PSU so I could run something like this!

…I will never have a processor like this.

Like many people are saying that’s 2.6W per core. Which is actually very good.

My laptop is running an Intel CPU with a TDP of 45W, which doesn’t seem as bad as that one until you realize that it’s only 6 cores meaning it uses 7.5W per core. If we multiply by the number of cores this CPU has we get 1440W if it were as inefficient as my Intel CPU, and that’s a very conservative estimate which assumes my CPU is as efficient as intel claims the Intel Core i7-9750H is, it actually might be much worse considering how hot this laptop gets, especially when gaming (though I don’t game on this laptop anymore for that reason).

Bottom line, this is a very efficient CPU, but it’s also an insanely ovepowered CPU that most people will not use or need. Only datacenters and extremely dedicated power users need a CPU anywhere near this powerful.

You must post before you leave

Be nice. Assume others have good intent (within reason).

Moderator Guidelines

Moderator Guidelines

  • Don’t be mean to users. Be gentle or neutral.
  • Most moderator actions which have a modlog message should include your username.
  • When in doubt about whether or not a user is problematic, send them a DM.
  • Don’t waste time debating/arguing with problematic users.
  • Assume the best, but don’t tolerate sealioning/just asking questions/concern trolling.
  • Ask another mod to take over cases you struggle with, if you get tired, or when things get personal.
  • Ask the other mods for advice when things get complicated.
  • Share everything you do in the mod matrix, both so several mods aren’t unknowingly handling the same issues, but also so you can receive feedback on what you intend to do.
  • Don’t rush mod actions. If a case doesn’t need to be handled right away, consider taking a short break before getting to it. This is to say, cool down and make room for feedback.
  • Don’t perform too much moderation in the comments, except if you want a verdict to be public or to ask people to dial a convo down/stop. Single comment warnings are okay.
  • Send users concise DMs about verdicts about them, such as bans etc, except in cases where it is clear we don’t want them at all, such as obvious transphobes. No need to notify someone they haven’t been banned of course.
  • Explain to a user why their behavior is problematic and how it is distressing others rather than engage with whatever they are saying. Ask them to avoid this in the future and send them packing if they do not comply.
  • First warn users, then temp ban them, then finally perma ban them when they break the rules or act inappropriately. Skip steps if necessary.
  • Use neutral statements like “this statement can be considered transphobic” rather than “you are being transphobic”.
  • No large decisions or actions without community input (polls or meta posts f.ex.).
  • Large internal decisions (such as ousting a mod) might require a vote, needing more than 50% of the votes to pass. Also consider asking the community for feedback.
  • Remember you are a voluntary moderator. You don’t get paid. Take a break when you need one. Perhaps ask another moderator to step in if necessary.
