Title: Difference between Sapphire 7970 and Sapphire Vaporx 7970 ? Post by: forexmasterja on June 24, 2013, 02:30:19 PM I would like to know what the real difference between these two GPU's ?
1# Sapphire Radeon HD 7970 OC with Boost 3GB DDR5 11197-03-40G 2# Sapphire Radeon Vapor-X HD 7970 GHz OC 3GB DDR5 (11197-12-40G Do both of them hash equally as well as the other ? can one be oc or undervolted more or something ?? Which one is the better buy ? in terms of Bitcoin hashing as well as scrypt hashing ? Title: Re: Difference between Sapphire 7970 and Sapphire Vaporx 7970 ? Post by: grue on June 24, 2013, 02:34:56 PM "Vapor-X" has custom cooling, so you can theoretically get better OC. It also looks like the "Vapor-X" version is factory overclocked.

So i'm thinking its better to go with the regular one instead of the vapor x and save some money as they both should achieve roughly the same hash results ..

The Vapor-X I found had a lot louder fans. So if you are concerned about fan noise the Vapor-X is a lot louder. In my experience for hash rate there isnt a lot of difference to be honest. The Hash Rates were roughly the same Title: Re: Difference between Sapphire 7970 and Sapphire Vaporx 7970 ?

The Hash Rates were roughly the same Great thanks for the reply. I'm just concerned about hash rate & power usage. So sounds like the regular will work ..

Post by: suprabitz on June 25, 2013, 01:53:20 PM i have both the dual-x and vapor-x. the vapor-x seem to run cooler at higher clocks. my vapor-x run steady at 680mhs <70 degrees @ 1.25v, my WF3 on the other hand won't go past 640mhs reliably. if you can get a vapor-x for $15-20 more, do it. the extra cooling is worth it. they are one of the thickest cards out there, i could not get 2 to fit side by side in a Haf XB because the width is wider than 2 slots, although you could do a 3 card setup with 2 vapor-x and a dual-x
my dual-x gets about 630-640mhs in the mid 70's. i have to say the sapphire cards are great for scrypt mining considering they're usually on sale, as are the WF3 with custom bios. |
