Yesterday i am test new Sapphire RX 550 2Gb DDR5 GPU
It give 300 H/s on stock frequencies, but if patch their timing easy get 450 H/s on cryptonote algo.
All need to do is:
1) Download bios rom image with GPU-Z,
2) Then open with polaris bios editor and click button "one click patch" and save rom
3) Then flash new image with ATI flasher
4) Patch drivers with atikmdag and reboot your rig
5) Set frequencies in MSI AB: Core clock 1250 memory 1900 Power limit +5
6) Test and enjoy

That's pretty good but the HD 7850 also does ~19.5 MH/s on Ethash coins with a <2GB Dag like UBQ, or ~80 cents/day with a ~3 month ROI.

http://whattomine.com/coins/173-ubq-ethash?utf8=%E2%9C%93&hr=19.0&p=130.0&fee=3.0&cost=0.12&hcost=80&commit=Calculate

The RX 550 is only ~30 cents/day on XMR.

I highly doubt that, my R9 380 with modified bios is doing only 21.5 at ethash algos

Although, your 7850 OCs really well, my MSI 7850 1GB version OCs only to 1350

Also, monero is not the frist option for cryptonight these days, there are more worthy coins
(although most of them are shitcoins, but hey, people still buy them

)

1020/1500 at -ethi 1 will get you 17.5-18 MH/s on Ethash with HD 7850 2GB card. At -ethi 4 you will get ~19.5 MH/s, but the cards will run at 80C< with the stock single fan.

Try mining dero with cryptonight algo.
If you need coin with purpose and more than just fork or gui wallet go for Dero,
research you coin first and read carefully the details about it.
https://github.com/deroproject/documentation/blob/master/WhitePaper.md
I am personally mining dero.
DERO: Privacy + Smart Contracts + Lightning Fast Transactions, like monero + ethereum
https://bitcointalksearch.org/topic/ann-dero-dag-cryptonote-bulletproofs-ssl-pow-smart-contracts-2525508
You can use cpu to mine dero.

How much power? HD 7850 does ~500 H/s @100 W for $60-80 on eBay.
