Might be time for an AMD CPU upgrade. To 105W or not to 105W? That is the question.

This was my first AMD CPU:

FX-8350
  • MT (multithread): 6,001
  • ST (single thread): 1,577
  • TDP: 125W
  • 8-core

I got the scores from CPU Benchmark. It worked fine, but it was fairly slow.

In August of 2020, I built a new AMD machine with this CPU:

Ryzen 5 3600
  • MT: 17,814
  • ST: 2,570
  • TDP: 65W
  • 6-core

I don't really have any complaints. Compared to the old FX-8350, the Ryzen 5 3600 is leaps & bounds faster. The only thing that I wish could run a bit more faster is RawTherapee, particularly when I'm batching hundreds to thousands of RAW files. It's far quicker than the old FX-8350, but it would be nice if it could still run faster than what it currently does. It would take the FX-8350 about +-10 seconds to convert a K-50 RAW file into a jpeg & about +-2.5 seconds for the Ryzen 5 3600.

After crunching numbers, seeing what's compatible with my Gigabyte B550 motherboard, & whatnot, I'm thinking of replacing that Ryzen 5 3600 CPU with one of the following CPUs:

Ryzen 7 5700X
  • MT: 26,624 (49% increase)
  • ST: 3,354 (31% increase)
  • TDP: 65W (0% increase)
  • 8-core
  • About +-$310 with cooler.

Ryzen 7 5800X

  • MT: 28,137 (58% increase)
  • ST: 3,448 (34% increase)
  • TDP: 105W (62% increase)
  • 8-core
  • About +-$370 with cooler.

Ryzen 9 5900X
  • MT: 39,313 (221% increase)
  • ST: 3,468 (35% increase)
  • TDP: 105W (62% increase)
  • 12-core
  • About +-$500 with cooler.

Ryzen 9 5950X
  • MT: 45,859 (257% increase)
  • ST: 3,464 (35% increase)
  • TDP: 105W (62% increase)
  • 16-core
  • About +-$650 with cooler.

AMD Ryzen 7 5800X Linux Performance Review - Phoronix

^ This link has a section where it shows a RawTherapee benchmark.

Ryzen 9 5900X = 45.85 seconds
Ryzen 9 5950X = 46.34 seconds
Ryzen 7 5800X = 49.32 seconds
Ryzen 7 5700X = +-51 seconds (guesstimate)
Ryzen 5 3600 = +-68 seconds (guesstimate)

I'm guessing benchmark figures for the Ryzen 5 3600 & 7 5700X, since they're not on the list. The Ryzen 9 5900X seems to be the fastest CPU that my motherboard can use for RawTherapee. Obviously, many other applications that I use on the PC would also benefit from a CPU upgrade.

So yeah. I'm just trying to figure out if the Ryzen 7 5700X will provide enough of a performance boost while "saving" energy with its TDP 65W design or just spring for the Ryzen 9 5900X/5950X that offers more performance, but with the increased energy consumption penalty. Ultimately, the 105W CPU draws more electricity. The Ryzen 7 5800X doesn't seem so attractive with its slight performance boost & much increased energy consumption. I would still be far ahead with the 5900X/5950X when compared to the old TDP 125W design of the FX-8350 in terms of power consumption, but I would rather save more energy if possible.

Like I said, the current Ryzen 5 3600 CPU works very well. Compared to the old AMD FX-8350, it's a night & day difference in speed. My machine has 64GB of RAM & a 500GB PCI-Express 3.0 m.2 drive. I might replace that m.2 drive with one that has a PCI-Express 4.0 x4 interface. They've come down in price compared to what they were selling for when I built the machine. It probably won't make much of a difference, though. All my files (documents, music, RAW, jpeg, etc.) are on an 8TB 7200RPM spinning drive that I got about a year ago.

I don't really need to upgrade anything else. The Radeon RX 580 video card is good enough for me. I don't play video games outside of using RetroArch to play old-skool NES, SNES, TurboGrafx-16, Genesis, PlayStation, Neo-Geo, Mame-arcade, & related. I don't edit video either.

Hmmm....... Get the 65W Ryzen 7 5700X or spring for the 105W Ryzen 9 5900X/5950X? There's a pretty big difference in performance, cost, & power consumption. Is it worth getting the speed with the cost or save money with less speed? It could be a difference of about $340 between the lowest & highest CPU, plus the energy use. I'd probably get it on Black Friday or Cyber Monday. Conundrum........

Sorry for the long post. Hahaha!

I am using Ryzen 5 5600G on home PC and Ryzen 7 5700X on work PC with nVidia GT 1030 2GB. What I can tell is that GPU plays a big role in Photo and Video editing as well as Encoding and Decoding (video). I am using Windows 10 on both PCs. Couple of days ago I have installed Alien skin X7 Bundle that checks your hardware upon first start to determinate either CPU or GPU will be used to process your editing. After the test I got a notification saying that using the GPU will be 2,65 times faster that using the CPU (5700x vs GT 1030).

If I were you I would get the 5700X + the best nVidia GPU for the rest of the money I can afford to spend. I will swap my 1030 with 1630 soon and see how big the difference will be.

Just an opinion I have had over the years: AMD processors are best paired with an AMD Video card. Although video cards can be easily twice as expensive as even the highest end desktop CPU I usually aim for products that are in the same price/performance bracket

For example I would pair an AMD 5800X CPU with a Radeon XT 6750.

Though with a TDP of 105W you are going to have to consider an appropriately efficient cooling solution. My current Intel systems are built around processor with a TDP of 125W and a video card TDP of 300W so you have to find a way to disperse that heat efficiently as possible, especially if you live in a region where ambient temperatures can reach 40°C as they can in the Australian Summers.

I believe the performance of Ryzen CPUs is meant to be strongly linked to the speed of the memory.

You said you've got 64GB. Would you know if it's DDR4 3200 or 3600 or whatever? And if it's running at that speed?

ETA: Regarding heat, since it's been mentioned above...
The advantage of 5000 series CPUs (I don't think 3000 series have the option, but may be wrong) is that you can set a negative voltage offset in the BIOS. The CPU does the same work, but slightly less voltage means less power consumption, means less excess heat to get rid off.
My 5600X has an offset of -20 (= 0.2 volts IIRC) and runs the best part of 10 degrees cooler as a result.

DDR4 3200 running at that speed with the XMP enabled in the motherboard. It runs slower when the XMP is disabled. I think at 2600 or something like that.

Are you sure that your current CPU is the limiting factor? Does your current setup provide sufficient cooling to prevent CPU throttling?

Unless the comparative CPU benchmarks were obtained using RT, which I imagine they were not, you may not realise the anticipated gains in practice.

Are you using your SSD to host your swap and RT cache files?

A better GPU, as suggested by Markovo, is unlikely to help as RT does not seem to have the ability to off-load image processing tasks to it.

Why not save money and batch process your files overnight?

If you are really desperate for a faster throughput, why not go the whole hog and upgrade to a Ryzen 7 Zen 4 platform: not immediately, but in the New Year when prices are likely to have come down?

Decisions, decisions 😁

The key to faster modern photo and video processing is matching a fast CPU with an appropriate video card that will allow you to use OpenCL to offload most of the data crunching to the video card. It often is 10X faster with the offload compared to doing it all on the CPU, even if you are multi-threading on the CPU. So I agree with Doug, a good video card is necessary but you do not need to get a top of the line gaming card. Just get a mid-tier one and be happy you did.

It's been a long time since I've built a PC, but I agree with comments above that the video card is very important, and the memory is too. Photo processing may not stress the system as much as gaming or maybe CAD, but it takes way more resources than web surfing, work processing, and even basic number crunching.

I agree, from what I understand AMD use a slightly different ram spec** than Intel systems, so you may have to consider this and budget accordingly. Also it is worthwhile to have each ram slot on the motherboard occupied rather than buy one stick of high capacity ram and call it a day, as again RAM performance can be impacted by heat - so if you spread out the area occupied by the ram modules less heat will be concentrated in a single area and also if a stick of ram fails* or develops some sort of fault you have redundancy.

* and extremely rare occurrence (about on par with being hit by lightning) but it can happen.

** though I think this has more to do with the high end Threadripper CPU's and may not be applicable to more consumer oriented products.

AFAIK RAW Therapy does not use the GPU for the RAW conversion. Thus a faster CPU, faster external storage (use a SSD while working on the files) and a good amount of RAM the options to speed up RAW Therapy. I might be wrong, but found nothing about GPU support in the internet.

If you want a RAW converter scaling with the GPU it is Affinity.

With Ryzen CPUs you have to make sure that your RAM is in Dual Channel mode as this gives you from 15 to 25% more performance gain over Single Channel in different cases.

Also, nVidia cards are way better in video decoding against AMD, maybe this applies in other hardware accelerations too...

I got GTX 1630 4GB which is half the price of RX580 4GB, yet 1630 plays 4K@60 in Premiere Pro without any lag. With RX580 it freezes after the 10'nth second...

Note: I am using Adobe products.
