Is it actually more powerful than a top of the line threadripper[0] or is that not a "personal computer" CPU by this definition? I feel like 64 cores would beat 20 on some workloads even if the 20 were way faster in single core performance. [0] https://www.amd.com/en/products/cpu/amd-ryzen-threadripper-3...

My workstation has a 3990x. Our "world" build is slightly faster on my M1 Max. https://twitter.com/kiratpandya/status/1457438725680480257 The 3990x runs a bit faster on the initial compile stage but the linking is single threaded and the M1 Max catches up at that point. I expect the M1 Ultra to crush the 3990x on compile time.

Intel was the single-threaded king until Zen3, so that's no real surprise.

Try the same thing with mold.

Wait, you can get a 3090?

Yeah. They've been in stock for months here (though the retailers are charging the inflated prices too), e.g. https://www.computeruniverse.net/en/c/hardware-components/nv...

All of those listed are WAY above MSRP! MSRP is $1,499 in the U.S. and £1,399 in the U.K.

SSD and those two large fans also use a fair amount of power too.

Those fans are unlikely to break 5w combined.

Guess we will see once one is available to be tested, but I doubt that’s the case. I was guessing 5-8W each, but I could be wrong of course.

I always take such claims with a grain of salt anyways. It usualy on one specific benchmark. I wait for better benchmarks always instead of trusting the marketing

Even if their claims are accurate, it usually has the asterisk of *Only with Apple Metal 2. I honestly cannot understand why Apple decided they needed to write their own graphics API when the rest of the world is working hard to get away from the biggest proprietary graphics API.

Because when they wrote the API no real standard existed to suit their needs.

I'd call them personal chips. When I think of non-personal chips I think IBM POWER or Ampere Altra.

Why do you think of Altera as non-personal chips?

Not Altera, Ampere Altra. This: https://amperecomputing.com/processors/ampere-altra/

If the purchase page says to "contact sales" and doesn't list a price then it is not for consumers.

You forget these things sit ~idle (or at browser load) 99% of the time. The magnitude of difference only expresses at peak consumption. Furthermore, what about the lost time/hassle for changeover plus embodied energy in throwing out the last system? It's insanity.

The average corporate PC device gets replaced every 39 months. Acceleration of that cycle with a Mac replacement, which usually has a 50-60 month lifecycle, is a pretty significant savings.

If those are real figures that's a good point :) I think we're well in to pedantry now. Call a somnambulance :)

To be fair here, there is more to it than just assembly. You have to spec out the parts, ensuring compatibility. Manage multiple orders and deliveries. Assemble it. Install drivers/configuration specific packages. All of these things are easier today than ten or twenty years ago - but assigning it to a random mid-level engineer and I'd set my project management gamble on half a day for the busiest, most focused engin…

PC part picker will do the heavy lifting for you. There are also management tools that will let you install software bundles easily, no real extra time investment.

Just knowing about services like PC Part Picker and the management tools you mention requires time and expertise that people generally do not have before they build a computer, so "no real extra time investment" may only be true for someone who can amortize those upfront costs across many builds.

In my case I have built a couple PCs before, but it was so long ago that I'd have to re-learn which retailers are trustworthy, what the new connection standards are these days, etc. It's just not worth it to me to spend a dozen hours learning, specing, ordering, assembling, installing, configuring, etc to save a few hundred bucks.

Where do you live that power is anywhere close to that expensive? And are you overclocking your 3090? Even assuming literal 24hr/day usage at a higher, "factory overclocked" 450w sustained, at a fairly high $0.30/kWh that's $1200/yr. Less than half the retail price of a 3090. And you can easily drop the power limit slider on a 3090 to take it down to 300-350w, likely without significantly impacting your workload perf…

prices in Europe right now are considerably higher than $0.30/kWh

It seems safe to say prices right now are not the norm due to, you know, that whole war thing going on that is impacting one of the EU's primary power supplies. The 2021 EU average was otherwise $0.22/kWh.

Since the context here is using these machines for work, a mid-level engineer will easily cost an extra $1000* in his own time to put that together :) EDIT: I’m quite confident this is not at all an exaggeration. Unless you have put together PCs for a living. $100/h (total employment cost, not just salary), 1-2 hours of actual build & setup, 8 more hours of speccing out parts, buying, taking delivery, installing stuf…

1000 bucks for 45 mins work? Maybe 1.5hrs tops? I didn't realise their wage was >500 an hour?

It would take me over 1.5 hours just to figure out what parts I need to buy.
