RE: Building a new Ryzen 7 rig

in STEMGeeks6 months ago

I've finally getting ready to build a new PC. The GPU of course has been the biggest hold up but I recently acquired a GTX 3060. Almost any modern PC has more computing power than I actually "need" but one of the things I like to do with them is run BOINC projects (and in the process mine Gridcoin though it isn't actually profitable or anything). I haven't pulled the trigger on the CPU yet but I am thinking of buying the 5700G instead of an X model. My thought process being that I'll get more total work done with the built in GPU than I will lose by having a slightly slower CPU. Plus it is cheaper.

Sort:  

Oh nice, I bet that RTX 3060 will be pretty sweet. I have a 3090 and it does everything and more that I need. Machine learning projects push it the furthest, but I also mine and game with.

Oh cool, I used to put computing power towards [email protected], [email protected], and [email protected] I tried out gridcoin but found it hard to earn any coins with their whitelisted projects. Seems half the time it would not mine me coins, just compute on BOINC. That was years ago though, maybe their interface works better now.

Best of luck, heres what you can expect mining XMR with that CPU:

I don't have any problem mining Gridcoin, it's just that it isn't worth very much. But I started using [email protected] way back before BOINC existed when my best computer was a 300 MHz Pentium II so I'm not really doing it for the money, it's just a nice bonus (and I can always hope Gridcoin skyrockets in value one day). Projects I use these days include [email protected], [email protected], world community grid and [email protected] Sadly, [email protected] was retired (or put into hibernation but I don't really expect it to come back).

Looking at that profitability website you linked I see that the 5800X can do 6542.7 H/s and the 5700G can do 4055.66 H/s. The 5800X usually benchmarks 5-10% faster than the 5700G so those numbers are questionable to me as it works out to nearly a 50% difference. Maybe XMR mining is able to take advantage of the extra cache? I can't think of anything else that would account for such a large difference. In any case, mining XMR doesn't appear to take great advantage of GPUs (hash rates seem pretty close for CPUs and GPUs). While the XMR numbers are pretty lousy, other things take better advantage of the built in Vega 8 graphics of the 5700G:

How profitable is mining with AMD Radeon(TM) Vega 8 Graphics?

AMD Radeon(TM) Vega 8 Graphics can generate more than 9.72 USD monthly income with a 3.43 MH/s hashrate on the RVN - KawPow (NBMiner) algorithm.
Algorithm Hashrate Monthly Income Monthly BTC Income Monthly USD Income
RVN - KawPow (NBMiner) ≈3.43 MH/s ≈90.19479902 RVN ≈0.00020835 BTC ≈9.72 USD
ETH - Ethash (Phoenix) 2.18 MH/s 0.00099030 ETH 0.00007992 BTC 3.73 USD
ETC - Ethash (Phoenix) 1.77 MH/s 0.04866885 ETC 0.00003636 BTC 1.70 USD
BTG - ZHash (LOL) 2.84 H/s 0.03414872 BTG 0.00003043 BTC 1.42 USD
XMR - RandomX (XMRig AMD) 102.98 H/s 0.00054273 XMR 0.00000265 BTC 0.13 USD

Yeah Monero implimented Randomx a few years back to combat ASICS. They went with a Cryptonight heavy algo first but then went to a more CPU exclusive algo called randomX which only CPUs are going to mine well.

I mine RVN (halving coming up) with my GPUs and then XMR with my CPUs.
