After the start of sales of new products from AMD - Radeon RX5700XT, the first information on the capabilities of these cards in mining cryptocurrency began to come. And this is not what many counted on, because All current versions of miners either do not work with this card or give a very low hashrate. At the moment, we managed to launch testing of the Radeon RX5700XT on the miner Phoenix 4.2 and Lolminer 0.8.3 and the test results were much worse than one would expect from video cards of this level. Most miners are primarily interested in the performance of Ethereum's cryptocurrency mining cards on the Ethash algorithm, where AMD cards have traditionally always had a significant advantage from competing Nvidia solutions, so well give the test results for this mining algorithm first.

The Radeon RX5700XT hashrate based on the Ethash (Ethereum) algorithm:
Phoenix 4.2c - 4 -4.5 MH / s

The result of 4 MH / s per second can be called frankly weak, since significantly weaker RX570 / 580 video cards use 29-33MH / s for this algorithm

For other Equihash, Cuckatoo algorithms, the situation is the same.

The Radeon RX5700XT hashrate on the Eguihash 192.7 (ZERO) algorithm:
Lollipops 0.8.3 - 0.67H / s

Hashreyt Radeon RX5700XT on the Eguihash 144,5 Zhash (BitcoinGold) algorithm:
Lolminer 0.8.3 - 0,2H/s

Hashreyte Radeon RX5700XT on the algorithm Cuckatoo31 GRIN31 (GRIN):
Lolminer 0.8.3 - 0,1H/s

It is the new RDNA architecture that should be blamed for this failure. All current miners for AMD video cards are optimized for the previous GCN architecture, and to fully unlock the potential of the new generation of AMD video cards in mining, you will have to be patient until the first miners with optimization for Navi video cards with RDNA architecture appear.

That's a complete cut and paste, and tells us nothing new. I see Claymore has a card and is testing it, which is excellent news. Fingers crossed we get RDNA mining figures soon...

I say that it is pretty much guaranteed, knowning claymore's reputation

What I fear is that we small miners will get a cut version and large mining farms a much more efficient one.

When others start to build code for RDNA then competition will force everyone to provide good performance to the public too.
