What is THE cheapest AMD-based GPU crunching solution? It is my beloved AM1 platform.
Mobo's as cheap as 25 Euro's can be combined with a quad-core Athlon 5350 that will take 40 Euro's out of your wallet and from there it is only the cost of a HDD or SSD and some RAM as I got plenty of old cases and PSUs, but I prefer iTX cases with a small -less than 100 Watt- internal PSU.
The Athlon 5350 has an internal R3 GPU with 128 shaders that will crunch for you, but don't expect wonders...

Time for some tinkering. Let's assume your name is Chris Crossfire and that you recently bought a secondhand FM1 mobo with room for three video cards (Yes, they do exist, got one of them myself).
Our hypothetical Chris Crossfire, always short on money, then goes hunting for a cheap secondhand FM1 APU. This can be even easier than the hunt for his mobo, as everybody wants to get rid of the FM1 thingies. The same goes for the cards that can be combined with the APU to go into Chris' namesake Crossfire, albeit the virtual branch of the family: HD 6450s, HD 6570s and HD 6670s.
Now Scole already warned that combining two (or more) cheap cards can end up worse than one supposedly expensive card in terms of GFLOPs and Watts -read Quids, Greenbacks- but I will take it into extremes here and let Chris go hunting for three dirt-cheap HD 6450s to combine with his Athlon A8-3850.

As he turns on his newly-built GPU cruncher, the power meter in his apartment shifts gear as the APU (100 Watt) and the three GPUs (some 25 Watt each) pull 175 Watt alone for roughly 1100 GFLOP. After some months of crunching his wife gets cross with him over the power bill and he has scored very little credits, BOINC-wise. So he decides to go crunching in the low tarif hours, but now he needs stronger GPUs and he trades his three HD 6450s (plus some extra) for three HD 6670s. Now he can pull 300 Watt out of the wall while crunching 2700 GFLOP, which leaves his wife utterly unimpressed (and BOINC likewise).

What should he have done? He should have bought a Radeon HD 7990, and relegate an easy GPU project to be run from the IGP of his APU while going full for the other GPU projects using -in the low tarif hours- the 375 Watt TDP HD 7990, as it does 8200 GFLOP (SP) alone and has considerable Double Precision capability too.

Linux kernel 5 and the rehabilitation of the AM1 platform.

You might remember that after Ubuntu 16.04 things went rotten with 'older' AMD cards and IPGs, but that has changed with the introduction of the latest Linux kernels.
At the moment I have an AM1 system with both the AMDGPU and the AMDGPU PRO driver running to my astonishment:

I am very interested, thanks. Can I use this on Ubuntu 19.04 with xeons please?

Also, how is the performance vs. AMD under Windows. Reason I ask is that I did get AMD cards working with 18.10 (I think) but the returns were very poor by comparison to what others were getting with same card under Windows. I am thinking particularly of RX580 crunching Einstein.

If you have installation instructions, I'll be happy to give it a try

Not sure what you mean. You want to crunch on the IGP of Xeon's? AMDGPU or AMDGPU PRO are not gonna help there. If you want to crunch on the IGP of a Xeon (or i9, i7, i5, i3, pentium, Celeron) you can use the new NEO compute driver under Linux. But running another discrete GPU alongside might pose problems. You might want to try to run a RX580 using both AMDGPU and AMDGPU PRO though...

Such a question can best be answered via WUProp. Go to their 'results' section and select e.g. GPU Credit for the RX580.

No, xeon (rather than anything AM1) will be the cpu platform. AMD RX580 or older for the GPU

YMMV: Check whether you have Linux Kernel 5.0 (or higher) first. If you have a crunching setup with the open-source AMDGPU driver for your RX580, install the latest 19.20 AMDGPU PRO driver -download at AMD- over it and keep your fingers crossed. Works for Moo!, Seti gives seg fault errors.

yup 5.0 according to https://www.zdnet.com/article/ubuntu-19 ... -0-kernel/

Just to keep you busy: There's a new Ubuntu/Xubuntu/Lubuntu: 20.04, with Kernel 5.4 and Boinc-Client 7.16.6

Now I didn't pinpoint the culprit yet, but 20.04 gives the well-known "No usable GPUs found", 7.16.6 adding the dreaded "GPU detection failed: process exited with status 1: Operation not permitted" --mind you: this is the very system that ran GPU tasks under two different drivers on its R3/HD8400 IGP under Xubuntu 18.04, as mentioned a few posts earlier in this thread.

Note the total lack of OpenCL, even that for the CPU (POCL). Clinfo gives "CommandLine Error: Option 'limited-coverage-experimental' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options"
The culprit seems to be that various parts needed for crunching have been compiled using the same LLVM version...

Partial success: Lubuntu 20.04 is now using its GPU -hat off to Oibaf. It -Lubuntu- didn't have the 'GPU detection failed: process exited with status 1: Operation not permitted' warning that Xubuntu 20.04 gave in the BOINC log in the first place.

L'histoire se répète (pardon me Klatchian): After the initial refusing of Xubuntu 20.04 to behave there was an update -and now it works as Ubuntu 18.04 did after kernel 5 came out.
Even more surprising was that Linux Mint 19.3 stopped seeing its IGP after that update and, after checking for the Intel Neo GPU driver it seemed to have disappeared. So I downloaded the latest one, installed it and - nothing. I searched for Intel-opencl-icd and found nothing. From sheer WTF I installed the ICD of the old intel driver, Beignet, and presto:

As the system is already swamped with one running GPU doing Collatz, I leave it be for the moment. If and when Seti and/or Seti beta come back to life, I'll experiment some more.

Article closes with "You can order the CAPA13R from the Axiomtek website now for an undisclosed price"...
But my guess is about 200-300 US$
This is a competitor, for a likewise price.

Can we get even more 'budget'? Yes, we can!
Another update, and I decided to separate GPUs and IGPs

These are most of the times the lowest that AMD could field in that generation. Cheap in both purchase and electricity bill afterwards -but zilch performance.

*=IGP, runs along for free with your CPU -which runs anyway while crunching, cheapskate!
