With great power comes great responsibility. What are you going to do with this beast?
Lock it to one core and pretend it's 2003, hopefully.
Still, I can see how limiting the number of cores might be helpful if the power bill becomes a concern.
Render, render all the things.
The irony is that this is probably more eco friendly than most powerful 2003 single core chips anyways.
I would have some applications for that in scientific computing. But more realistically jackhead could render stuff in blender while the encoding h265 and playing a modern game, with two players on the same machine (2 screens etc) playing online, all while hosting a semi-succesful website, and have a few cores idle.
I guess you would ROCK in the fold@home project.
i think biggest part of such samples are the price, you can get such one much cheaper as the latest i7 with great performance if you need cores.
By the way seller add the 22 core ^^.
Not mine, but here's a 133 on eBay.
Awesome setup. Glad you got it working!
So I just though of that thread because I got to play with such a system nowadays...
2 x 18C/32T Xeons with 128GB ram and a P4000...
It's satisfying to see all threads and RAM at 100% at the same time... Gotta love OpenMP.
@Jackhead, what is cache and frequencies of your engineering sample?
My workstation at home:
2x 12C/24T Xeon X5670 with 96GB CL7 DDR3 ram and a RX 480 8GB
It usually cross-compile arch linux i686 and arm packages inside VM's. Still very fast for such a old system.
Sometimes you can grab these machines very cheap, too.
I don't own the one I use, sadly, I'm just crunching numbers on that thing. I couldn't afford it anyways (>10k CAD, and it's negligible vs the data acquisition card that's plugged into it).
Still, it's a lot of fun to play with!
Wait, isn't that Xeon 6C/12T? So you have 24T total on the system?
This would be basically the same workstations we had in 2012. Still very powerful nowadays, just upgrade to an SSD!
The workstation I got right now has total 36C/72T. At the same frequency as my development i7-8550u 4C/8T laptop that I use to test the code, the workstation, with 9x the cores/threads, is at least 16x faster on parallel loads, often higher, probably because of cache/features.
Yes, one Xeon is 6C/12T. But this Workstation has two of them in it (Sharing RAM via NUMA). Total usable 12C/24T
I got a SATA SSD in it, too. The machine still handles all load easy. Only drawback is its doubled 95W TDP.
Can't put a M.2 PCIe in it because I already used all slots. The machine is filled up. I didn't even had space left for the SAS Expander card. The solution was to power it up with a cheap x16 mining riser. While deliver data via two SAS cables going into the HBA card. The Expander now sits isolated near the drive bay.
Indeed, the Cache size at these Xeons is just massive compared to its little brothers. It helps a lot when playing with big numbers
Could you tell me the model name of the workstation at your work? I'm curious about it. Seems very powerful.
Technically, it's at university, not at work.
It's a HP Z840 with dual Xeon E5-2697 v4. The cooling is good so it stabilizes at 2.7 GHz under continuous 100% load. It's very noisy though, but the environment is even noisier so you don't really hear it.
Separate names with a comma.
