Gunther got a transplant tonight, as Amazon brought me a new toy today in the form of an AMD Ryzen 9 3900X. This replaces the 7 1700 that I had been rocking for the last 3ish years.
That 1700 originally came in Gus, my Dell gaming PC that I picked up cheap and got me back into performance computing (and sim racing) after many, many years away. Gus’s heart got transplanted into Gunther, my X470 current rig. Paired with a robust power solution on an MSI X470 gaming M7 AC board and an EVGA CLC 280mm aio, Gus’s old heart proved his mettle running rock solid ever since on a 3.8gz all-core overclock.
With the advent of
competitive folding w/Oppo, combined with Uncle Sam’s bonus, I decided to move up the planned upgrade to a 3800x for my birthday in a month or two. Poking around Amazon revealed processors have dropped considerably since the last time I looked, so I upped the ante and clicked on the 3900x option.
How is it? Holy shit is this thing fast. Completely stock BIOS settings and letting the PBO do its thing have it running ~4.1-4.2 ghz on all 12 cores under load at reasonable 68 degrees. In terms of performance, it folds a CPU work unit that took my significantly overclocked Ryzen 7 1700 about an hour and half to two hours to complete, and does it in about 30 minutes pulling about 145 watts at the socket. With 70MB of cache, this is thing is snappy at everything I ask it to do.
Based on what I’ve seen so far, I feel no need to overclock this thing. I’m probably just going to leave things on auto and enjoy life without the need to upgrade my CPU for some time to come.
Buying a more expensive board with a robust power solution now pays off.
The cooler works even better and gets off minimum fan and pump speeds when I remember to plug the aio USB cable back in after a fresh dot of Artic MX-4.
It also came with a fairly beefy looking wraith cooler. I’m not running it, but it might come in handy depending on what I decided to do with the old 1700.
