I have 7850 graphics card. Can I mine DOGE? Will it be effective? What do you suggest?

your best bet would be an scrypt ASIC.
As a reference: https://bitmakler.net/asic you can look for SCRYPT asics from this list. They should give you the best performance instead of GPU or CPU.

That being said, theoretically, you should be able to mine with a GPU, according to this list: https://litecoin.info/Mining_hardware_comparison , your card should hash at a rate between 300 and 400 kH/s. Compare it to the asics in the above list and see the difference ;)

EDIT: do be carefull with the list of bitmakler, next to listing legit asics, i have just noticed he also lists scams/hoaxes... If you ever want to buy an asic, it would be best to find a more trustworthy seller's list

I don't want to spend extra money for mining. I just wonder if I mine with my own equipment. I guess it's not worth mining. Thanks for your reply.

Since Scrypt algorithm can be mined with (scrypt) ASIC, mining DOGE with GPU is not effective.
Of course, you can try merged mining, but it's still not effective.

I suggest you find a coin better suited for GPU mining (some say that ETH/ETC is a good choice) and, if you want DOGE, sell the mined coins and buy DOGE.

In other words, mining ETH with this card should result in a hashrate of 15.940.347 (~16MH/s)

https://badmofo.github.io/ethereum-mining-calculator/ tells me that's about 40 bucks (USD) a month worth of ETH at current diff and ETH price. Don't know about the power draw of this setup tough... Keep in mind you also have to pay for your electricity ;)

Depends on if the 7850 has 1 or 2 GB of ram. If it is the 1GB version you won't be able to mine ETH

I've got a HD 7850 2GB card, best I've ever seen out of it is about 10 MH/s mining ETH (which IS profitable, the repurposed low-end machine that card is in soaks a little less than 200 watts total or about $6/month at my electric rate vs a little over $20/month for the last couple months in earnings - I DO have a very low electric rate but the card would still be profitable at a fair bit over 10c/KWH electric rate).
 Card itself I'd estimate is eating 120-140 watts of that usage.

 My pair of 7870 machines do a HAIR better, but they have memory that handles higher memory clocks and seem to soak about 10 more watts.

 That published "16MHs" figure is from ETH early days when the DAG file was a TON smaller and everything hashed faster as a result.

 As another poster mentioned, you NEED to have a 2GB version of the card to mine ETH on it.


 Forget Scrypt - those cards never even got to 700KH/s while the first-gen ASIC gear (5 chip Gridseed Orbs) managed better than half that on about ONE TENTH of the power usage - and are no longer even break-even unless your power is super-cheap.
 I've never seen Scrypt numbers for the RX 480/470 but I seriously doubt even THOSE cards would be break-even on Scrypt - I'd guess they're probably 2-3 times the hashrate of a 7850 at a little lower power usage.

 DOGE isn't even really ASIC territory any more - most of the DOGE "hashrate" comes from folks doing merge-mining on Litecoin.

Yes, it's 1 GB model and I have no interest mining ETH. I only want to mine DOGE if possible but it seems it doesn't even handle the electricity cost.

Mining XMR might still be profitable, depending on your electricity rate.

You gotta hack the bios and you can get 14-15MH/s out of your 7850. Needs to be 2GB however.

Not bad considering the 280x get 18mh/s

 Perhaps XMR then.

Give up the idea of mining DOGE - it's nothing more than a "merged mining" coin, most or all of the hashrate on it is from folks merge mining it from Litecoin 'cause DOGE isn't worth hardly anything any more.
