My personal opinion is XMR is gonna fuck something up, RandomX isn't going to be the magic bullet they think it will and they will eventually be forced to embrace ASICs.
Well they have put in a lot of work in RandomX and have made some changes to it to further harden it to be ASIC resistant until the code freeze in April.

https://github.com/tevador/RandomX/issues/11Single-chip ASIC design:
https://github.com/tevador/RandomX/issues/31New AMD chips are also putting out 1/2 the hash of a full R815 on a single chip for a 1/3 of the juice.
And for those miners they will have to purchase new AMD CPU's and motherboards. Those are costs we don't have to experience as we already have the hardware.
I am doing some minor (and cheap) upgrades to the Dell R815's by purchasing some Opteron Upgrades that will pay out for higher Hash rates and lower power.
Purchased 10x AMD 12-core 6348 Opteron's for a total of $64.10. These along with 2x 12-core 6348 Opteron's from a Supermicro server will going in three of my Dell R815 servers.
Purchased 8x AMD 16-core 6378 Opteron's for a total of $69.29. These will be going into my other two Dell R815 servers.
Purchased 2x AMD 16-core 6376 Opteron's for a total of $24.67. These will be going into the Supermicro server that had the 6348 Opteron's in it.
As for power used. Yes it will be higher power and "Hashes per watt" will be lower but if the profit is high enough then that works for me.
This is what I am measuring for a Dell R815 Server with 4x AMD 12-core 6348 Opterons:
Idle Power: 265 watts
Mining Power: 865 watts - That is after the warmup period. It starts at 800 watts and slowly climbs and peaks at the 865 watt number.
RandomX Hash rate: 10629 H/s overall or 2657 H/s for each AMD 12-core 6348 Opteron.
Dell R815 Server RandomX "Hashes per watt": 12.3
I'm hoping they will make something, but I really feel like these servers along with a lot of other things I bought over a year ago were a fools folly.
We should make some profit mining RandomX on the Dell R815's. Not so much (or at all on the HP DL580 G7's).
Also remember that no one should be mining RandomX with GPU's and that botnet mining should be also a thing in the past and that a lot of current miners have Celerons for their processors driving large GPU mining rigs. Those Celerons are pretty useless for RandomX mining.
