Unfortunately I don’t have enough adapters on the PSU to use both, so does anybody know which GPU is better at mining Zcash?! ---

> [@gatekeeper01](#): > > oh wow really? with no miners at all? lol Those cards are 3 generations behind. Too old for Zcash or ETH. They can mine other things though. ---

That’s what I was told trying to get a 6950 to work. No support at all. You would prob get 5 sol/s anyways ---

yeah, but i figure with 9 + 5 (or however many it would be), it wouldn’t entirely be in vain on the off chance that zcash one day takes off ---

This is correct ☹ However I would note the 7870s and 7850s are great pulling ~33 H/s for pretty low power consumption. ---

I wouldn’t want those GPUs for FREE even. Get a second hand Radeon 7850 or 7870 for like $20. You will get 30 Sol/s. You can sell that GPU next year for the same price, no depreciation. ---

I have a 7850 and mining on nheqminer for windows. But I’m only getting 35 sol/s WITH cpu mining. Is there something I can do to increase my GPU-only hash rate? ---

Buy the 7850 in your local Craigslist or Kijiji. They shouldn’t cost anymore than $30 these days. Get the 2GB ---

that’s an amazing deal, but you won’t find them that cheap unless you’re really lucky, even on craigslist or kajiji ---

Most people aren’t miners and those are very old GPUs. They aren’t good for games anymore, most people sell them cheap. ---

yes, i understand all of that, but the avg price for either is roughly anywhere from $80 upwards, despite the age of the cards ---

Where are you checking? eBay might be overpriced right now due to ZEC. Try Craigslist or Kijiji and look for 7870 and 270x also. ---

You can also buy a 7950 probably for like $80-100. Those get 70 Sol/s [Next page](https://forum.zcashcommunity.com/t/hd-6850-vs-hd-5850-which-is-better/7779.md?page=2)
