Hey guys
Quick question here, apart from Ethash and Cryptonight, is there any other algos where AMD cards perform well ?
Neoscrypt, Lyra2v2, Equihash are competitive to various degrees --- you can mine Xevan and Nist5 too but they don't compete with Nvidia very well there. I'm probably also forgetting some other options.
The last time tried running Lyra2v2 on an RX 570 - about 2 months ago - it was unbelievably slow; as in, more than 10x slower than a GTX 1060. I've seen mention of a new Lyra2v2 miner for AMD on the forum, but since I rarely mine with that algo, anyway (snagging a few VTC here and there), I haven't bothered trying it.
From my testing notes, AMD does deliver competitive performance on Neoscrypt vs. a similarly priced Nvidia card (based on MSRP). E.g. - my RX 570 does 720 kH/s using the old version of Gateless Gate (no GUI, no devfee) while each of my GTX 1060 do 650 kH/s using the KlausT fork of ccminer, and a claimed 720 kH/s with Palgin's hsrminer_neoscrypt (emphasis on "claimed" and his program is a bit unstable).
I haven't tried Xevan on AMD - I'm not aware of any miner programs for it, actually (NB - this doesn't mean there isn't one!) - but since this algo seems to be only used on shady MasterNode coins I have only done brief testing with ccminer-alexis78 on Nvidia.
Same with X17, NIST5, etc... There just doesn't seem to be as much variety in miner software for AMD to support these less popular algos, probably because AMD is so vastly superior at Cryptonight and Ethash it makes little sense to use it on anything else.
