> At a conservative estimate of $25 million for the array to be constructed, the auction sale is only 2% of the sticker price of Cheyenne.
Honestly $480k sounds like a fair price. This is 8 year old hardware, in any reasonable depreciation scheme the book value is $0. If you just flip it you probably break about even, considering that prices are not going to be able to sell 8000 of those Xeon processors at their current market price.
If you just want the compute, this supercomputer is equivalent to about $70000 in modern GPUs (assuming your compute needs fit the processing model of GPUs), so even with free power it's not terribly attractive to buy the system to run it yourself.
I’ve paid for a motherboard of a off-lease hardware because even though it was about the price of a tune new off-lease server, it was simpler for me than rebuilding the OS for a newer piece of hardware. And data center equipment is so fast to swap even motherboards. If a CPU burned out in this I’d just get another.
It would be better to invest on something what would track the things you need and notify you if the price drops or there is a surge in availability.
And an anecdote to complement this:
I have 1155 desktop PC with Pentium G2020 (2cores/2threads, ugh). I can fit almost anything Ivy/Sandy Bridge in the mobo, but...
i7 3770 is still $300, while various refurb Xeons E3 v2 are $20-30.
And the best part is what even if I buy something like 1270v2 (4c/8t, full eq for 3770) it would still be a more than a decade old system and it wouldn't improve the performance much.
There are, of course refurb/secondhand 3770 out there, but...
Just let me copy-paste one of the lots out there:
$33 e3 1270 v2 SR0P6 3.5-3.9mhz tdp 69w = core i7 3770k
$39 e3 1275 v2 SR0PA 3.5-3.9mhz tdp 77w = core i7 3770k with Intel HD Graphics P4000
$44 core i7 3770 SR0PK 3.4-3.9mhz tdp 77w
$43 core i7 3770S SR0РN 3.1-3.9mhz tdр 65w I have 1155 desktop PC with Pentium G2020 ... even if I buy something like 1270v2 ...
it would still be a more than a decade old system and it wouldn't improve the
performance much.
That depends. For the small 3 node cluster of HP Microservers (Gen 8) in my home lab, they had cpus of the Pentium G2020 class. Upgrading those to the Xeon E3-1265L v2 (also 4c/8t) made a huge difference.The G2020 has 3MB of cache, whereas the E3 above has 8MB and clocks higher.
Then again, the workload on these little boxes is mostly running VMs for build jobs. More cores is definitely better than less cores for that. :)
Three (pretty big) caveats to add:
* Any significant quantity of those CPUs and RAM sticks hitting the used market at once will depress the selling price. So they need to be sold over several years during which the baseline demand (and price) will continue to fall.
* The sale contract had fairly onerous requirements about the professional personnel and methods of removal permitted, all of which will add to the buyer's upfront costs on top of transport, storage and sales costs.
* Since there are known failed components in the lot, all the pulled parts will need to be tested or sold as-is.
I'm surprised it got bids that high and I think the article implying the buyer got a steal is overblown.
Might be a case of actual recycling being the best course of action.
It can be hard to know how well your CPU is going to perform with the instructions you generate until you have it tbh. You could get a sense of how fast it is compared to other processors with benchmarks. But I don't know how accurate it's going to be overall. A lot of the time you end up with unexpected results; CPUs that seem cheap are usually cheap for a reason though.
But imo, the power consumption is just not worth it. Might just switch to a regular desktop running an i5.
Sort of how the electricity of mining a bitcoin is orders of magnitude more expensive than just buying a bitcoin.
A S21 Hydro can do a terahash for 16 joules.
At the current difficulty, you need approx 525,000 kWh to mine a bitcoin.
At $0.16 a kWh, you’re looking at $84k to mine a bitcoin, worth $63k. That’s not orders of magnitudes higher.
If you can get cheaper electricity and are willing to pay the capex then you can make a profit.
I guess I haven't been keeping up with bitcoin vs electricity cost. I was going to buy a bitcoin miner when bitcoin was ~$500 and in short order the electricity cost of running the miner exceeded the cost of bitcoin and started getting worse.
Now with bitcoin value > 1000x ... hmmm. maybe my assumptions are plain wrong.
Unclear how much of the cost is hardware vs energy vs infrastructure. I would assume hardware is the cheapest part but I could be wrong
Thanks! Macro-expanded:
