Opinion or Argument on 9590,9370, Clocked 8350 Or Not?

post #1 of 18
Thread Starter 
I reckon 9370 and 9590 are diffrent circits than 8350

CPU manufatures dosen't take a 1.248V CPU and overvolt to 1.44V

CPu manufactures don't overclock

If its a clocked 8350 chances are it has a high failue rate which means they will warranty more


Chances are the avaliblity of 9370 and 9590 will be extremely low
as there will be a lot of bad clocking 8350s
thus low avalibility and insane prices

Allot of FX cpu that are not 9series take stupid volts for high clocks

If you look online some guys can't get it clocking and it needs stupid volts
+ I had 2 8350 and both were so bad at overclocking that posting results is a shame
+ a 4300 that is also bad at clocks 1.608V for 4.8GHZ

Chances are that the golden 8350s are a updated circuit since it would increace clockablity but manfacutring price is same

Golden 8350 may be a beta version of 9590 or 9370, it failed to meet requiremts of their planned 9370 CPU so downgraded to 8350 before a formal release

Whats your opinion?

FX-9K series SKUs use dies with so extreme leakage characteristics, that they could never be sold as FX-8K series SKUs. Even if they are downclocked to same specifications as FX-8K series their power consumption and current draw would violate the infrastructure specifications (95 / 125W TDP). If AMD hadn´t create the 220W TDP infrastructure for AM3+, the parts now sold as FX-9K parts would have been sent to the crusher.

Relative leakage:

FX-9590 = 11.9 (avg)
FX-8370 = ~16.6 (avg)
FX-8370E = ~ 21.5 (avg)

The first FX-8350s had significantly higher leakage, around 14 on average.
Higher (lower leakage) is better, depending on cooling.

What effects leakage? Circuit design ?

The base line (nominal) leakage is defined by the manufacturing process and the design. Existence of low and high SIDD parts is just a deviation to either direction.

So it means a diffrence core design for lower leakage?

No.

You mean its clocked 8350?

I feel like lower leakage means more clocks even.on air up to l2n

Yes, as stated above the fx 9xxx series are a different bin of the same silicon and it is the same silicon in all the 8xxx and 9xxx chips

Diffrent oppinions?
Chanses of amd making a good bin Selling as 9590?
I think its too low to be pratical as i stated before thus manufacures do not oc or over volt their chips and sell

FX-9K CPUs are technically identical to every other Vishera.
They just have different leakage characteristics than the rest of them.

Excess leakage is always bad, however too low leakage is no good either. On ultra low leakage specimens you are likely to run into the voltage limit, before the chip has reached it´s maximum clocks. Ultra low SIDD parts are useless on LN2 as you cannot raise the voltage infinitely.

For air / water you want around 88% (19) of the minimum, for phase around 79% (17) of the minimum and around <74% (16) for extreme LN2 runs. Anything below 14 is useless garbage IMO biggrin.gif
