Title: 7990 hashing speed? Post by: jasinlee on April 09, 2013, 11:57:52 PM Anyone got a speed on the 7990, cannot seem to find info on its speed for btc or ltc?

So its basically a 5970 for current day. So that would put the cap of 8 gpus on each rig as usual. But potentially faster than any other options so you could have 4 7990s @ 5.2gh/s or 2.4gh/s for 4 7950s? Title: Re: 7990 hashing speed?

Now you can only have 4 7990s, but IIRC, most of them are triple-wide, so good luck fitting 4 of them inside any case, or on any MB. |
