Sapphire 7970 Dual-X vs Sapphire 7970 Ghz Ed. Vapor-X

post #1 of 22
Thread Starter 
Is the Vapor-X worth 60€ of difference?
What about the OC and noise on the standard Dual-X and the coil whining on the Vapor-X?
Thanks

It really is a silicon lottery when it comes to the Sapphire Vapor-X and Dual-X IMHO, I have a Sapphire 7950 OC edition with the dual-X fans and I'm able to OC it to 1200/1600 (stable benching and gaming for hours and hours) without unlocking anything (though I did use the 2nd BIOS) and I'm lucky that mine doesn't have any coil whining at all.

The noise levels for the dual-x is very good, if you leave it at auto, you will never hear it over your case fans. You can set fan profiles if you want a more aggressive profile via trixx or MSI AB. When gaming, I hit 70~71*C max when at 1200/1600 and I leave the fan profile at auto. That's pretty good for an OCd card used for hours and hours!

If you look at this test from OCC they were only able to push their card and have it stable at 1175/1661. I believe the sapphire cards that are binned are the toxic edition cards.

So to basically answer your question if it's worth 60 euros more... well no. thumb.gif

I'm almost positive they both ship with the same pcb right now, barring old stock obviously.

So basically the vapor-x is the same card with a factory oc and different fans?

I dont have dual x but I have Vapor x. And when I was searching for gpu, Ive read that Vapor x has a different cooler. Vapor x chamber was sapphire' company's distinctive cooler. So dual x and vapor x has a different cooler. Same board? I dont think so. From what ive read Dual X has a reference board where as vapor x has a costumized board.

Yep. Look for yourself. Click on the picture box and view the back of the pcb/card pic.

There is a bios switch on the dual-x that changes the core to 1000MHz and memory to 1450MHz from 950 and 1425 on the first bios. Don't remember if it changes the voltage.

This is what the product page says.

"Its Dual BIOS switch allows users to select the higher performance settings of 1GHz core and 1450MHz memory, making the fastest card in its class. This setting also uses a more aggressive fan profile and raises the limits for maximum overclocking."

Is it the "Ghz" bios? How many bios are there?

Anyway in the basic sapphire dual-x there is not dual bios, only for the OC version. Can I get a good OC on that version too? Or flash it with a better official bios?

i have Xfired vapor-x's and the bios switches are useless...they dont change anything...both cards out of the box (ordered 3 months apart) are 1050mhz core/1500mhz mem, while the switch lights up when you push it, it doesnt change the clocks (as seen in MSI/CCC/GPU-Z)

my first one i think i pushed a little hard benching and its stable point seems to be 1181 mhz core, my second card can stay at 1200 when i benched it by itself...when xfired i keep both at 1181 mhz core
