I've joined the TechPowerUp team. :3
Thanks
My Farm currently looks like this:
This is my main system with 3950X. It has 32GB of 3600 MHz C16-16-16 RAM. I am going to let it crunch non stop for a few days, since I was rendering lots of videos lately and playing Metro Exodus which I like to give quite a lot of threads to. So now it is time for SCIENCE!
Forgive the dust (>_<) on the left is my Ryzen 7 2700 system, with 16GB 2400 Mhz 14-16-16 RAM. On the right is the Ryzen 5 2600X system with 16GB of 2933 MHz 16-18-18 RAM. The Ryzen 5 2600X is running in "cTDP" Down mode, set to 65W. The clock speed is about 3.3-3.4 GHz on all 6 cores at 100% load in WCG. The 2700 is running stock, at 70W PPT, with clock speeds only slighty lower at 3.2 GHz ish.
Last but definitely not least of my machines, I have my downstairs living room PC, which pulls double duty as a gaming system with Xbox 360 controller for sofa gaming. ^-^. This machine has a Ryzen 7 3700X and 16 GB of 3200 MHz 16-18-18 memory. The 3700X is also running with a tweaked PPT, set to 65W in Ryzen master. The clock speeds are around 3.6-3.7 GHz on all 8 cores at 100% load in WCG.
I have plans to get another full time rig, as I wish to take advantage of sales on 2nd gen Ryzen parts like the 2700 which is really insanely good price now. In fact, it is so well priced that if you consider cost of investment relative to cost of running, it is cheaper to buy and run 2700 for 2-3 years than a 3700X. Because I am saving £150+ on the initial investment. Perf/watt is lower of course, but even 2nd gen Ryzen is pretty efficient at <65W.
One more PC, which I am now going to break into WCG, is my mum's slim mATX tower upstairs. This has a Ryzen 5 3400G, but with only 8GB single-channel 3200 MHz memory, at 14-14-14.
All of my PCs use about ~650W combined. This is actually slightly less than my 2x1700+2700X+2700+2600X+(some other parts) setup prior. Zen2 efficiency and the cTDP down on the 2600X are helping in PPD/W here. By the way: this also includes, speakers, monitors, router and such. According to the WCG website, I have broken 60K PPD before I have started up the 3400G system. With that online, my Farm will have 42 cores and 84 threads. 24 of those cores are Zen2 architecture @ 3.6-3.7 GHz, and 18 of them are Zen+ architecture, with 14 of those running at 3.3 GHz (ish) and the other four at 3.8 GHz.
I have a Ryzen 3 1200 lying around here somewhere. I am in the process of moving my setup into the attic room (mother's wishes
)))) and once I have done that, I will add those 4 Zen1 cores to the mix.
As I said earlier, I have plans for at least one more full-time crunching machine, which will most likely have a Ryzen 7 2700 in it. Or perhaps the 2700X, since deals are good on those and it's very nice to be able to use PBO to configure the PPT on the fly.
For example, my 3950X is configured @ 105W PPT (contrary to some belief, the 105W "TDP" isn't the power use, but that's another story. 105W "TDP" = 146W PPT (Socket Power)). I switch between 95 and 105W depending on workload. I will note that the processor gets hotter in bursty workloads (gaming + 40% crunch) because the cores enter higher power states and use mroe voltage. I see around 4 GHz on all 16 cores in these workloads @ 105W, and 3.9 @ 95. In full WCG, I see 3.8 GHz on all 16 cores at 105W PPT absolute socket power, and 3.65 at 95W. I do this because I am trying to restrict the thermal load on my motherboard for full-time WCG, and my heatsink probably won't be able to cope with 16 cores at 4 GHz+ (stock 146 W PPT).
Zen2 is such a huge boon for efficient computing. I am so excited for the Zen3 parts, mainly so Zen2 parts can be had for (hopefully) similar deals like Zen+ is today. Human progress I think.
Sorry for the long post >-<"
