Threadripper

Post by stevenramsey » Mon Jan 15, 2018 1:01 pm

Has anyone used and compared a Threadripper versus a i7 for cyclone, especially the import and unify functions.

Hi!!

I now this is a bit old post... but I hope it helps you

I have 2 setup:

First one:
TR 2950x
64 Gb RAM
2 Tb SSD + 4 Tb HDD
GPU: Quadrp P4000

Second one:
i7 8700K
64 Gb RAM
1 Tb NvME + 4 Tb Hdd
GPU: GTX 1080 Ti

Wih the i7 machine I have been working for more than a year without problems, for a import of 90 SW it took like 30 min to 1 hour less than the Threadripper machine. I have the theory that Cyclone prefers higher clocks speed. I want to make a video comparision to probe this theory.

It definitely seems to prefer clock speed. I'm sure the extra cores help for multi tasking, but I'm not sure how many cores it will actually utilize. Some processes, cloud optimization i believe, seem to be locked using 1 core. Others like the import process use all cores.

My setup:

i7 8700K @ 4.8GHz
64 Gb RAM ddr4 3200
1 Tb PCIe NvME
GTX 1070 Ti @2100MHz

Last timed import was:
73 scans
52.3 GB of data
14 min. import

Interestingly, gpu utilization doesn't go above 50% and it is only under any significant load during import.

When I run the adminastrator task it appers Cyclone use all cores, but again, it seems speed> clock.

I'm glad you point out the GPU used, that something really frustrates me, because I could save money on a lower GPU and use it on better NvME or more RAM. I dont know if there some changes you have to make on preferences to take more advantage of the GPU.

Also I see you overclock your CPU up to 4.8 GHz, I try to but Cyclone crashes more than usual, any advice?

Just take it slow.

Get some monitoring software. I use NZXT CAM to moniter speed, load and temps, but I know there's a bunch of options.

It took me a couple weeks to find a comfortable OC level. I'm not sure what would cause Cyclone to crash. Could be your CPU thermal throttling after you OC it and Cyclone doesn't know what to do with the constant changes in clock speed, but I'm just guessing.

I built my office rig and two others so I had a good starting idea of what they could handle. I started at 4.5 I think and processed scans for a couple days, ended up getting up to 5GHz but started seeing thermal issues on bigger projects. So I ended up at 4.8 being my best threshold between speed and safety.

That would be my main advice, take it slow. Other than that it's going to come down to you cooling and power options that determine what the cpu can handle. Our scan processing computers are all liquid cooled AIO options. They're an easy upgrade over those large heatsinks.

+1 and great post. Problem with overclocking is that it works better on shorter tasks than longer where heat can build up over time, including ambient heat in the room. Last thing you need if for the workstation to blue screen 10 hours into a 12 hour task, or worse, fry the CPU or mobo. If your office is warmer in the summer, you may also need to notch down you OC speeds to account for this.

Reviews suggest threadripper CPUs manage power pretty well and manual OC gains are somewhat more marginal than Intel as the auto settings are well tuned. Looking forward to series 3 on Ryzen and reckon we'll see a doubling up on threadripper cores given we're going to see 32 threads at 5.1ghz boost on the Ryzen 3850x. AMD have certainly laid down the gauntlet to Intel.

Are you running your NVME on PCIE (x16)? If not your missing out and not really taking advantage of the power of the Threadripper.

I'm not running threadripper in my current build. Hopefully I'll get the green light to build a monster in the future. I would love to run multiple nvme drives in a raid 0 configuration. 6 GB/s claims sound nice but I've also heard it's a mess currently trying to get multiple nvme drives to play nice in raid configurations.

I ran a Raid 0 with 3 NvME with Kingston A1000 of 1 Tb each, there is not a lot of how to do it, but I made it worked for a while until I notice that it take a lot of time to open any program, sometime like 2 to 3 minutos to open Excel!!!!!

I ask for support from Kingston, but to say the least it wasn't very useful. So rigth now I just have a 2 Tb SSD :cry:

I'm waiting to have some money to buy the Asus Hyper M.2 with 4 Samsung 2 Tb NvME :D

We use a number of threadripper 2990wx and a mix of i7-i9. I would strongly stray away from AIO coolers. Loved them at first but when (not if) they die it can be massively frustrating. 2990wx under load as a pump fails means blue screen in seconds. A Noctua cooler and a well-ventilated case, nothing crazy, is all you need.

Oh and don't overclock. Do you want the best ROI? Get the overclockable chips and don't overclock. Retail gear is not built for 24-hour loads every week. K or X series Intel chips are binned for just that reason. They passed tests in the factory for thermal and voltage. They should last.

Know your software. Most programs run processes in 1 of 3 ways.

Single thread: Intel current wins here. Clock speed wins.

2-4 threads: this is when you may want an i9 or AMD 1950. Make sure to assign core affinity.

64+ Threads: this is where duel Xeon and AMD 2990wx come in. Clock speed is not everything here. You need to look at core count L1/L2/L3 cache and how well your system can move data. Methods like this are generally suitable for a single task with many of said tasks Q’d up.

Play around with a 1950 build. Great bang for your buck and should provide a lot of headroom to upgrade. 2x Samsung 970pro or evo NVMe 1Tb should be all you need. Don’t raid 0. Export to second drive. By working on a second drive much of the systems auto temp files and caching won’t slow down your IO response rate.

I hope this was helpful.
