Insights or advise about: AMD Ryzen 5/7 CPU's and NVIDIA GTX/RTX GPU's

As a matter of interest: also check Ryzen 9 3900X, and a suitable X570 motherboard. Also check the difference between 4 * 8 gig and 2 * 16gig RAM (or 4 * 4 gig versus 2 *8 gig). Some say RAM speed is the most important, others say that CL is the important factor.

PS: Also - is your distro able to handle an RTX gfx?

Have fun!

Both versions are 65W according to the specs, it was one of the first things I looked at.

The wattage is one of the reason I opted out of the ryzen 9. There’s also the price: I don’t think the extra cores and speed are worth it, not in my case anyway.

The choice is mainly based on the HD’s I have/want. Had a little mishap mid last year and bought 3 WD’s RED (2TB each. 2 in a RAID 0 setup). I like to reuse those together with a fast, small os/system SATA600 ssd disk and possibly (money…) a 1TB NVMe “work” area. The board I mentioned has enough sata/m.2 slots to handle that and possible future add-ons.

It is one of the parts that I need to think about real hard! Might opt to put the 3 WD’s in an encasing of their own and make them external.

Too expensive and it runs on 105W. I don’t think that the 12 cores and 300MHz speed increase is worth the investment. I did have a good look at them though!

That is one of the things I’m still looking into. I haven’t been able to find DDR4-3200 8Gb memory by brands that I know/trust. Have to read some more reviews and tests before I make a decision about that. That is assuming 4x4 is faster then 2x8 on dual channel board…

I was hoping that someone here would have experience already with the RTX2060 on a Linux box.

For those that might be interested what I decided to do. After more reading and some internal deliberation I’ve chosen the following core components:

  • MSI B450M MORTAR MAX
  • AMD Ryzen 5 3600
  • ASUS Turbo GeForce RTX 2060 SUPER EVO
  • Corsair 16 GB DDR4-3200 (2x8)

Also decided it was time for a new monitor:

  • DELL UltraSharp U2719DC

I have really enjoyed my Dell Ultrasharp 24" monitors, good choice!

Never had a Dell before so I’m curious how this experience will be.

Read a lot of good things about Ultrasharps by end users (you, among others, in a few threads on this board).

Specs of this particular one looked nice, 27" is right at the outer edge what I think is still comfortable for a 2560x1440 (W)QHD monitor and the price is reasonable.

Heard of Dell panel lottery?
If not better look up, I have personal experience with my (then) expensive 30" Dell. Few years later I cherry-picked wife’s U2711 from several, thanks to the accommodating shop. Not perfect but much better than my 30" model which was exchanged two times for infamous purple-green tinted panel problem.
Smaller, like paperdigits 24" panel are usually better.

Spread the word and demand normal monitors. None of my CRT’s had such problems and this is called progress!?

whoa 2060 super even. you really went all in :slight_smile:

Yeah :slight_smile:

The super is about 15% faster, runs on 175W (vs 225W) and is supported on my platform. Worth the extra 50 or so euro’s.

You seemed to be worried about peak power usage, but the higher-core-count processors run at lower all-core clock speeds and run more efficiently (consume less energy) for accomplishing the same task. Plus they’re faster on multithreaded workloads like image processing.

I have a 2700X right now and kind of want to upgrade, even though it’s really not worth it.

It isn’t something I’m worried about but power usage did play a roll as one of the deciding factors.

That’s good info to know and that’s the reason why the rtx2060 Super runs more efficient then its predecessor. This not being limited to CPU’s.

Not worth it; Exactly! I’ve thought about spending the extra roughly 120,- to go for the Ryzen 7 3700X instead of the 5 3600. In the end I didn’t really see the point and spend some of that to upgrade to the RTX2060 Super.

16GB RAM seems kind of sub-minimal for an “upgrade”. More is always better in the RAM department. In my experience RAM (the amount) is crucial. My “personal “minimal” systems have 64GB on Mac and 32GB on Windows. Systems I make for clients have 128-256GB RAM and a 10,000 Base-T card to borrow a neighbor’s memory in case of RAM shortages…

Yes you only need 4GB to launch the software, but you want it to run :running_woman: so give it a long track.

Taking prices into consideration, I would also opt for 32GB RAM. For my setup I chose relatively inexpensive non-overclocking-RAM (Crucial 16GB DDR4-2666 UDIMM | CT16G4DFD8266 | Crucial DE).
For my 2nd Generation Ryzen 2700X RAM specification was given at 2933MHz so 2666MHz was fast enough for my taste. 3rd Gen Ryzen 3700X supports 3200MHz, so faster RAM will probably be more expensive.
I go for RAM that natively supports the frequency speed as my personal experience with overclocking RAM has been less successful.

Depending on the setup, have an eye on the BIOS settings. In my case, after a BIOS update, my settings were reset without me realizing it. The Auto setting tried to overclock my RAM by increasing its voltage to 1,35V instead of the correct 1,2V, having me sitting there and wondering why all of the sudden my system became unstable.

True as a blanket statement. However…

I did some testing with my current 12 GB RAM (+12 GB swap) setup and I only reach the point when swap is actually being used when I start doing things I do not normally do. I do, very often run multiple instances of for example darktable, GIMP and/or krita at the same time next to all the normal stuff that is running and this is handled nicely with the current 12 GB RAM.

As a result of those test I decided to go with 16GB DDR4-3200 (2x8 on a dual channel board). The board does have 4 slots so I am able to add another 16 if needed.

I’ve never dipped into the overclocking pool, be it CPU’s or RAM. I might be wrong but I get the impression that the extra heat it generates, does, in the end, shorten the lifespan of those components.

I feel you, however I have weird experiences myself. I’ll be looking soon for something more recent than Dell T3500 that I own for couple years that is way more powerfull. I need to state this though: I thought 12GB was ok for me, till the company required dumb electron-based communication software.
Today my T3500 has 24GB of ram with 12GB swap and it CAN swap. Intel xeon with 4 cores and 8 threads doesn’t seem to be that much of a help these days and since the board can’t do atomics I can’t use ROCm if I were to upgrade cards…

I’ll try to get something similar to your config in the future.

Well, seven years ago, configuring the 8-core FX 8350 machine I still use, when RAM wasn’t as cheap as today, I bought 32 GB of slower RAM instead of 16 GB faster RAM

Downsides of the decision: When using all cores, my machine is more limited by RAM bandwidth

Upsides of the decision: Because of the bandwidth limitation I could make more improvements to RawTherapee to avoid these :wink:

Requirements and, for most people, money dictate what it is you are going to buy, be it an off-the-shelf box or one that you build from components you choose yourself. I’ll keep you informed on how this setup will hold based on running the stuff I mentioned in my original post.

Right now I’m using an almost 10 year old system: Intel I7 950 3GHz 4 cores (8HT), NVIDIA GTX 460 and 12GB on an ASUS P6T V2 board (the nicest board I’ve had thus far). At the time it was state-of-the-art and I’m amazed how long I’ve been happy with it and how reliable it has been (never a hitch). Still good in some ways even though it has to work harder and harder to keep up… It’s going to be a nice 2nd computer.

Check the part numbers of the RAM sticks carefully; some are reportedly better for Ryzen use :slight_smile: Follow the recommendations of the MB manufacturer…

If you don’t also upgrade your heat transduction system overclocking will shorten MTBF, the mean time between failures. Overclocking also pushes the signal phase stability envelope toward physical limitations, your cpu, ram, and therefor computation all become more sensitive to ESD. If you can mitigate those limitations overclocking to 80% of the maximum frequency gain differential is ok based on a round-number headroom value. Your maximum will be determined by the transistor junction temperature in the cpu. The temperature is probed on the reverse side and thru the package. The BIOS and OS use the info to set fan voltage or pulse width. My cpu and heat sink will go up to 5.0GHz under full load before the chip thermal limiter cuts off power. It is rated for 3.9GHz maximum turbo frequency. That’s a difference of 1.1GHz. 80% of 1.1 is .88 so it runs normally at 3.9 + .88 = 4.78GHz. Going much past 5 would be pushing the frequency and phase-stability limitation of the motherboard, unless you’ve got some new hyper-spec 20G-integrity board.
I think many BIOS utilities will sense all this automatically after a number of reboots if you have a clock-unlocked processor.

Thanks for that piece of information.

Seeing this mentioned is rather nice. The Ryzen 5 3600 is unlocked and the MSI B450M board is fully gen 3 ready. So this should work nicely.
