Title: Which 7950? Post by: denrok on July 15, 2016, 12:02:15 PM I'm looking to upgrade to a gpu mining rig and on a budget, i've seen that the 7950's come recommended but unsure which brand to go with, people seem to prefer the saphire, msi ones?
I was specifically looking at this one http://cdn.videocardz.com/1/2013/02/Sapphire-HD-7950-Boost-3GB-1.jpg would it be suitable or can someone recommend something else. Title: Re: Which 7950? Post by: Genoil on July 16, 2016, 10:11:09 AM No. Spend a bit more on a used R9 380, 390 or new RX480. 7950 are cheap but old, power hungry and not good at ETH any longer.
Title: Re: Which 7950? Post by: Arnoldent on July 16, 2016, 02:31:50 PM It is better to buy a used R9 390 to mine the Ethereum or the RX 480. The 7950 is too old and not efficient.

Title: Re: Which 7950? Post by: adaseb on July 19, 2016, 08:21:52 PM The 7950 uses the EXACT same amount of powers per mhs as a 380/390. All these GPUs are old 28nm technology. If you pay alot for power you need to either get the rx 480 or nvidia 1070. Title: Re: Which 7950?

7950 TDP is 140W I sold all mine, so i have no interest, but it could be great on a budget. You can get two, hashing at 34mh at less than $200, using maybe 280w (for GPU only). I say that it is good to try, but if you want long term, then RX 480. RX 480 (without undervolting, etc) is 22-24 mh using 140-150W for $240-250 PLUS tax=$260-270. TL;DR 7950 low price, RX480 higher price, but more mh/watt. Title: Re: Which 7950? Post by: Q_R_V on July 20, 2016, 10:03:06 AM You didn't told us how much you pay for KWh, if your electricity is cheap and don't want to spend much, 7950 might be not bad idea.
Title: Re: Which 7950? Post by: QuintLeo on July 20, 2016, 08:02:39 PM 7950 with at least 2 GB isn't a bad choice for Ethereum mining, especially since they can commonly be had quite cheaply.
The only real diff between the HD79xx/HD78xx series cards and their "R9 2xx" and "R9 3xx" replacements were BIOS updates, the actual GPU chips were often the same (or at most relabled). Down side - older, used, dunno how hard of usage cards are a bit higher risk. |
