I'd really didn't expect as much... So now I have to figure out either how to kludge CUDA to work with my unsupported GPU *or* update OpenCL so that it sees my GPU. Any suggestions on which track I should try first? This is important for me.
The proprietary Nvidia drivers (not nouveau) includes all the OpenCL libs needed. However CUDA will not work with OPENCL and vice versa. The are different, competing compute APIs (one proprietary and one open source). Also, Nvidia does not support CUDA development on all of its GPUs. If you need to build OpenCL applications on Nvidia GPU, start here: https://developer.nvidia.com/opencl

Thanks a lot kingB. I am thinking about upgrading my GPU but I can't decide if I should go with AMD -or- stay with Nvidia. Going with AMD has at least two big incentives:

1) Get a lot more GPU for my $
2) Freeing myself of the need to rebuild the Nvidia proprietary driver/kernel mods every time I upgrade my kernel (which I do often).

My current low-end Nvidia GPU [1030 GT] as it turns out is supported and working with Cuda TK and Cuda NN libs. This (Cuda) facilitates building the Neural Network based App (https://github.com/lightvector/KataGo) that I would be mainly upgrading for. The aforementioned App however simply will *not* compile with the current stock Slackware OpenCL libraries. It is even mentioned on that site that linux OpenCL drivers are problematic - yet the Windows pre-compiled binaries seem to work fine with the OpenCL based version.

So if I were to make the jump to AMD I would most certainly be relying on your SlackBuild (or the one on Slackbuilds.org) to support it.

I don't suppose you would be willing to direct me here? Maybe even see if you can build the above App on your box?

wirelessmc, the mesa OpenCL aren't quite ready (esp. for AMD). You'll need the AMD OpenCL stack from AMDGPU-PRO or perhaps ROCm (although newer NAVI are not supported and their build system organization give me hives). If you run AMD on Windows, that driver (Adrenalin 2020 Edition) will of course have all the OpenCL bits and work fine. The Linux equivalent is AMDGPU-PRO. Thus my post here as a "workaround" for the F/OSS amdgpu kernel module/driver.

1) and 2) were also my reasons to drop Nvidia for AMD when Current hit kernel 5.4.x (5.8 would be better). I'm pleased with the decision so far, although it was mainly for games and BOINC. Now, after a kernel update I need to do ... nothing ... to update amdgpu. sweet!

I just did a big upgrade on the current boxes, and updated to amdgpu-opencl-20.30. I'll give KataGo a shot here soon while I'm updating and rebuilding all my SBo stuff. DM me the build options etc you use. They also report it to be buggy on RX 5700, so I will build and also test on a RX 590 I have. This will be on Slackware64-current so you'll have a baseline.

Hi, I replaced my RX580 with RX 5700 XT and opencl stopped working on RX 5700 XT. I did more digging and I got to work again on RX 5700 XT.
It looks like RX580 will use libamdocl-orca64.so for opencl and RX 5700 XT will use libamdocl64.so but I had to copy libdrm_amdgpu.so.1.0.0 from libdrm-amdgpu-amdgpu1_2.4.100-1109583_amd64.deb replacing slackware one. Also I left only amdocl64.icd in /etc/OpenCL/vendors.

It looks like RX580 will use libamdocl-orca64.so for opencl and RX 5700 XT will use libamdocl64.so but I had to copy libdrm_amdgpu.so.1.0.0 from libdrm-amdgpu-amdgpu1_2.4.100-1109583_amd64.deb replacing slackware one. Also I left only amdocl64.icd in /etc/OpenCL/vendors.
Well, heck. I was not expecting that. I was wondering what was up when I upgraded using amdgpu-pro 20.30. Given all the updates to current, I was looking in the wrong area...

Thanks,
Ed

I'm not able to get amdgpu-opencl based on amdgpu-pro-20.30 to work. Rolled back to 20.10. I'm not quite sure what's missing. jedrek.b workaround did not work. I'll update the TP. EDIT: seems I can't edit the top post. So i'll just drop this here.

Testing using 800 visits.
  If you have a good GPU, you might increase this using "-visits N" to get more accurate results.
  If you have a weak GPU and this is taking forever, you can decrease it instead to finish the benchmark faster.

You are currently using the OpenCL version of KataGo.
If you have a strong GPU capable of FP16 tensor cores (e.g. RTX2080), using the Cuda version of KataGo instead may give a mild performance boost.

Your GTP config is currently set to use numSearchThreads = 6

Ordered summary of results: 

numSearchThreads =  5: 10 / 10 positions, visits/s = 385.99 nnEvals/s = 339.66 nnBatches/s = 136.54 avgBatchSize = 2.49 (20.8 secs) (EloDiff baseline)
numSearchThreads =  6: 10 / 10 positions, visits/s = 432.82 nnEvals/s = 382.11 nnBatches/s = 128.18 avgBatchSize = 2.98 (18.6 secs) (EloDiff +39)
numSearchThreads =  8: 10 / 10 positions, visits/s = 457.40 nnEvals/s = 400.83 nnBatches/s = 101.17 avgBatchSize = 3.96 (17.6 secs) (EloDiff +51)
numSearchThreads = 10: 10 / 10 positions, visits/s = 444.73 nnEvals/s = 389.87 nnBatches/s = 78.94 avgBatchSize = 4.94 (18.2 secs) (EloDiff +33)
numSearchThreads = 12: 10 / 10 positions, visits/s = 472.84 nnEvals/s = 425.73 nnBatches/s = 71.95 avgBatchSize = 5.92 (17.2 secs) (EloDiff +48)

Based on some test data, each speed doubling gains perhaps ~250 Elo by searching deeper.
Based on some test data, each thread costs perhaps 7 Elo if using 800 visits, and 2 Elo if using 5000 visits (by making MCTS worse).
So APPROXIMATELY based on this benchmark, if you intend to do a 5 second search: 
numSearchThreads =  5: (baseline)
numSearchThreads =  6:   +39 Elo
numSearchThreads =  8:   +51 Elo (recommended)
numSearchThreads = 10:   +33 Elo
numSearchThreads = 12:   +48 Elo
numSearchThreads = 20:   -44 Elo
During the benchmark run, the RX 5700 XT spiked to 106 C (3066 rpm) and 110 C (3215 rpm) for 20-30 seconds. From clinfo, KataGo chose the correct OpenCL platform (Creating context for OpenCL Platform: AMD Accelerated Parallel Processing). OpenCL GPU compute issues seem to have been patched with the AMDGPU-PRO-20.x drivers.

Wow! These are outstanding results KingB! I am so grateful for you making the effort and volunteering your time to do this!
The benchmark data is truly telling. As a data point my measly little Nvidia 1030 GT GPU (compiled katago with the Cuda backend) is only optimum at 5 search threads where your RX 5700 XT is optimum at 8 search threads. That's an 80% improvement. Huge! Were any other packages needed to build it? i.e. other than your custom AMDGPU Slackbuild? Thanks so much! This is all I needed to see to sway me over to AMD for my next investment in GPU.

@wirelessmc:
Just added my admgpu-opencl-20.10 package to a stock Slackware64-current (12-Sept-2020) multilib (due to my Steam/WINE gaming addiction). Stock X.org and Mesa. There are a few libs (WxPython, wxGTK3), codecs and apps from SBo but nothing that KataGo needs AFAIK from the build log (but I didn't look too closely). As soon as I find the RX590 and the PCI-e riser adapter for the Ryzen 7 3800X miniITX system, I'll compile there to check, and maybe compare to the GTX 590 (fastest Nvidia I still own). That box is pure Slackware64-current.

By the way, I forgot that while the benchmark was running, I had a qemu VM running Slackware64-14.2 to compile QT5.

Well many, many more kudos and appreciation out to you kingbeowulf!! This is some outstanding work/development you have done getting the AMDGPU code working on Slackware. The Slackware community is a better place because of your contributions! It will be interesting to see GTX 590 fares in this benchmark.
