With the upcoming Monero (XMR) hardfork to the RandomX algo in a day now, we are checking what is the current profitability of crypto coins that are already using the RandomX algorithm or a variant of it on a decent performing AMD CPU that offers great price/performance. For the tests we are using an AMD Ryzen 5 3600 processor that is 6 Core – 12 Threads with a base clock of 3.6 GHz and max boost clock of up to 4.2 GHz running at stock settings on a B450 motherboard with 8GB 3200 MHz DDR4 memory. The hashrates below are from the latest XMRig 5.0.1 and the algorithms tested are RandomARQ (RandomX variant for ArQmA), RandomWOW (RandomX variant for Wownero) and RandomXL (RandomX variant for Loki) and tomorrow we would be able to see profit results from Monero’s new RandomX algorithm after the fork as well…

XMRig 5.0.1 on Ryzen 3600 CPU:
– RandomARQ – 22600 H/s – 29.1963 ARQ – $0.28 USD daily profit
– RandomWOW – 5700 H/s – 91.1030 WOW – $0.28 USD daily profit
– RandomXL – 5900 H/s – 1.2837 LOKI – $0.53 USD daily profit

As you can see even though the performance in terms of H/s is quite good, the profitability of a single Ryzen 3600 CPU is far from great and when you consider that the power usage of a system with that processor is about 130-150W you get let us say 3.6 KW per day with cheap $0.1 USD per KW/h for the electricity that results in $0.36 electricity cost. The only coin and algorithm that is currently above the electricity cost is LOKI and you won’t actually be making much, just paying for the cost of the CPU can take quite some time and here we are all hoping that after the fork of Monero things will be looking better for miners with CPUs. Intel CPU owners might be mostly interested in ArQmA (ARQ) as the variation of the RandomX algorithm it uses performs much better on Intel compared to the version from LOKI or Wownero that are significantly faster on AMD Ryzen.

Monero (XMR) will be hardforking tomorrow, November 30th, at block number 1978433. The fork will change the current CryptoNight R algorithm for mining to the new Random X PoW algorithm, essentially moving the mining of the coin to CPU. There are already a few RandomX miners out there that you can use, links below, and although some f them also support AMD or Nvidia GPUs, you would probably want to stick to CPU mining with RandomX as the algorithm is optimized for processors and GPU mining performance is far to low currently to be considered. Also as already noted AMD’s Ryzen 3000 series of processors is doing great for Random X and performance wise it is much better than recent Intel alternatives.

Another important thing to note regarding the upcoming for is if you are mining directly to an exchange using a paymentID. Since after the fork support for PaymentIDs will be discontinued, in order to continue successfully mining after the network update you need to also update your mining address. Alternatively you can just update to the latest v0.15.0.1 wallet and use a local wallet address for mining after the fork. For an up to date pools for mining XMR you can check the list at MiningPoolStats, they should all be ready for the fork by now.

Mining software with RandomX support:
XMRig 5.0.0
SRBMiner-MULTI 0.1.7

Just a few days after the official launch of the Nervos (CKB) mainnet and GPU mining the Eaglesong algorithm may alterady become pointless with FPGAs apparently getting support for the algorithm. First was the information about FPGA support available for the EagleSong algorithm with bitstreams and miners available for Alveo U200 and Xilinx VCU1525 FPGAs. Now Hash Altcon has also announced support for Nervos CKB mining on their Blackminer F1 series of FPGAs with the CKB bitstream to be released soon. They state Eaglesong hashrate of 22 GH/S with power usage of 1020 Watts (1.1 GH/S for single GTX 1080 Ti with 200W of power usage), so definitely more efficient than GPUs. This is signaling the end of GPU mining for Nervos (CKB) and a move onto FPGA mining for sure. There was a pick in mining hashrate yesterday when first new of FPGA support broke out, though today it is lower, with Blackminers F1 joining the game in the next few days there will most likely be another spike in hashrate… depending on profitability of course. With the slow difficulty adjustment that Nervos (CKB) currently uses there may still be some more time left for GPU mining, though even at the moment profitability does not seem attractive at all.
