Radeon VII (2nd gen consumer Vega GPU)

[tServo]

I added "notify me when in stock" to the Radeon listings in Newegg but no luck:
I was downstairs feeding the cats when my phone buzzed to tell me they were in stock.
I went upstairs and they were sold out!
Total elapsed time: 4 minutes!

I guess I would need to get an app on my phone and instantly jump on it.
I'll bet the quantities coming in are low anyway.

They're apparently fantastic for mining Ethereum: https://cryptomining-blog.com/10628-...ut-of-the-box/

Basically three times faster than the GTX 1070, which was one of the better cards previously.

I thought all that hoohah had subsided judging by the flood of mining rigs and cards available on Ebay the past couple of months.

On the graph, click on the 1year or max view to see how its value has crashed.

It has. There could be a resurgence in mining if crypto picks up again but right now it's enthusiasts and speculators only.

Radeon vii is in stock now on amd.com for anyone interested in buying it. (At least in the US)

Also some places in EU (for example computeruniverse.net, Germany) have PowerColor cards in stock. Of course they don't say how many... but they do show how many times it's been ordered in the last 30 days. 12 for the PowerColor version, 4 for MSI (still not in stock), 1 for XFX (not in stock either), 1 for ASRock (not in stock). So maybe supply hasn't been great, but demand isn't that hot either.

Overclockers have Powercolor cards in stock at £650 in the UK. They've had 10+ in stock for a day now. Powercolor are the worst of the bunch as they only have a 2 year warranty compared to 3 for the rest, FWIW.

Radeon VII gpuowl benchmark at stock settings, these are out of the box numbers using the default performance levels. Using a daily build of Ubuntu Disco (upcoming 19.04) with 5.0.0 kernel. ROCm using upstream. Not headless, GPU was driving display which may have had a tiny impact on performance. Performance level set with rocm-smi --setsclk #, default fan speed and memory clocks. PRP on an 89M exponent using 5M FFT, latest gpuowl. Test bench is a Ryzen 1700 idling, 16GB of RAM and a gold rated PSU.

Numbers can be improved by overclocking the memory and undervolting the core. Tried a basic memory overclock by setting memory OD to 19% in rocm-smi which upped mclk to 1192. At perf level 8 it was doing 0.95 ms/it but I only ran it for 5 minutes as it was hitting the 250W power cap so the figure is not very useful. An undervolt should improve efficiency considerably but I haven't figured out how to do that or change the perf level presets properly yet (amdgpu.ppfeaturemask=0xffffffff is in grub and pp_od_clk_voltage is present in /sys... however pushing "s 4 1547 1050" or whatever doesn't work, nor does --setslevel or --setmlevel in rocm-smi. Pro drivers required?).

Wow, impressive! LL/PRP performance crown - taken.

[preda]

Nice! better than I expected.

IMO the sweet-spot seems to be at --setsclk 4 (with default voltages).

I think the manual undervolting may be broken, feel free to report bugs to AMD maybe they'll look into them. (e.g. to "ROCM issues").

Could you measure a FFT 4608K exponent too? (84M).

You know that you have to commit the change, I think by writing a line with a single "c" at the end? A sequence of "s ...." lines, and a single "c" at the end.
