Imas kakav link za tih 50%?
Koliko znam AMD nije nista mjenjao na procesorima, samo su smanjili napon i frekvenciju da dobiju manji TDP.
Smanjili su leakage na Puma arhitekturi ali nigdje nisam vidio da su spominjali ista za Piledriver/Visheru.
Imam vlastito iskustvo.

Pogledaj po netu testove ljudi koji imaju te nove Vishere.
Rezultati su zapanjujuci.

Mozes prolistat pa pogledat moje testove FX8370.
Apsolutno nemoguca misija za "stare" Vishere s takvim voltazama.

A 8370 je 125w.

Pogledaj sto kaze Stilt,prenosim samo bitan dio teksta:

Piledriver module based Vishera die has been mass-produced in two different die revisions since the prototyping phase.
While all of the revisions have the same major die version (OR-C0), the minor revision has changed.
Initially the first mass-produced die revision was "India" (OR-C0i, prototype and ES only), the second revision was and still is "Juliett" (OR-C0j, retail) and now finally...
The "Kilo" revision (OR-C0k) a.k.a "King Vishera" a.k.a "Vishera Type-K" has arrived.

The "King Vishera" is initially only available in the new models, FX-8370E & FX-8370.
This is most likely the case with FX-8320E also, however I have not been able to test one of them personally.
The new version is likely to be phased-in at least in the other high-end models such as FX-9590 and at some point in all of the remaining models also.
The alledged metal tapeout of the new revision (alledgedly) occured in the beginning of July. So the only way to get a newer revision part is to get one of the new models, atleast in the beginning.

The differences?

- On average 18% less leakage*1 (0-38%) for FX-8370
- On average 53% less leakage*1 (14-106%) for FX-8370E
- Up to 300MHz higher overclocking margin *12
- 100mV less voltage required for the same clocks on average *1

*1 - Compared to an average FX-8320 or FX-8350 CPU
*2 - When not restricted by the cooling or the motherboard (VRM)

The E-version is the best choice for air or water cooling thanks to the ultra low leakage characteristics.
The non E-version does the same clocks however it might require use of a higher end motherboard (with better VRM) and high-performance cooling.
The non E-version has significantly better overclockability under sub-zero temperatures (phase, LN2) since the leakage levels of the E-version are too low for the purpose.
Having an ultra low leakage characteristics is great under normal conditions however under sub-zero temperatures the voltage requirements become a issue.
Basically the low leakage part exhaust the usable range of supply voltage prior reaching it's maximum frequency.

Based on my own tests, I would estimate that >95% of FX-8370 & FX-8370E parts will reach 4.8GHz frequency in 24/7 without a custom watercooling or a ultra high-end motherboard being a requirement.
As long as the temperature (see below) stays =<65 degree C or 149 degree F and the motherboard has even remotely a sufficient VRM you'll be fine.
