Technically speaking the lower the voltage the better.

AMD you cant get 4ghz cus its very high.
Itd be like 6ghz on an intel.
i dont think so. the two processors are identical wafers and build and therefore should possess the same resistance to electricity which means the resistance, R should theoratically be the same. Therefore when supply higher voltage it means when the R is constant and V is different for two instances, the amount of Amp, A is higher and this is essentially what runs any electrical component. V=IR conversely V/R=I, whereby V is voltage applied, R is resistance and I is induction or Amps.

therefore if two processors are identical and supplied two different voltages then the amount of energy available for the higher voltaged processor is more. this is why we increase voltage to overcome resistance and give more power to a cpu, ram or some other electrical component.

To get an AMD processor to 4GHz on a workstation without extreme cooling is not at this time possible.

You can pump it up with phase.

4.0 is not impossible. But you need a VERY good chip along with LN2 and the chip will be unstable at 4.0 anyways. The difference between the FX-60 and the 4800+ is price, speed, and the FX-60 has unlocked multipliers.

sccr64472, y cant i do 4.0GHz with AMD? i have never used AMD and thats why i am asking. with intel i know a little but with AMD i m a dim wit so plz explain
You're equating cpu speed to performance and that's simply not the correct picture. Yes, an identical cpu running at a higher mhz will outperform the slower cpu. However, AMD processors can outperform much faster Intel processors because of the architecture. Think of it as a low reving V8 engine against a high reving V6....rpms don't mean anything. If you read up further, you'll find that Intel has given up on the high mhz processor development and has decided to work on more efficient processors. Their newest endeavor will not even break the 2.66 ghz mark, but will be far faster than the 3.8 ghz P4 lineup. Currently, AMD processors can execute 9 instructions per clock cycle, while P4 cpus execute 6. If you're wanting technical reasoning as to why you can't hit 4 ghz with an AMD processor, you can find information discussing the bus length and number of stages that will explain it to you. The chances of you hitting 4 ghz are best with an FX-57, but they are VERY,VERY slim.

i am sorry if i appear to be a little blunt but apart from this, is there anything else different between the two? because the way i reason it, if the FX60's advantage is only the unlocked multiplier and even this some reviewers are saying is cannot be operated above 14.5x and it can only reach 2.9GHz on air then might as well not go for it.

if there is some other reason then that warrants further consideration .

edit: i understand sccr64472, now lets forget the question of intel and amd. instead if we just look at the FX60 and 4800+; what would be the difference between these two very identical cpus

If you give into rumors, the FX series is supposed to be the handpicked best of the best chips from the wafer. The multipliers are left unlocked and they're priced at a premium because of this. No, having a higher multiplier won't be useful because you won't ever use it. If you want the very best chance at getting a supreme overclock, buy the FX-60. If you're looking for the best deal, then don't. Either way, give up on the 4 ghz mark that's stuck in your head because you're not gonna get there, even with phase change.

Yeah there's no chance your gona get 4.0GHz on an AMD right now.

The FX's have unlocked muti's and I also heard they have the best wafers, meaning the best oc's and performance.

ok i cannot get 4.0GHz on AMD. i understand that but can some1 answer the most important question that i asked about the difference between the FX and the 4800+? our we only paying a premium ONLY for the best wafer and unlocked multiplier? which in this case has been tested to only go as far as 2.9GHz on air even with increased voltage?

i am very inquisitive and have been asking this question to myself the whole day. if only someone can tell me.

ok since no one is answering this i want to ask this question in hypothesis; if FX is the best on Dual core AMD has to offer and so far it can only be clocked reliably upto 2.9GHz does that mean whichever dual core u buy it can only be oced to the limit of the FX?

NO chance with normal phase to get 4ghz with ANY AMD chip out right now. You need like triple cascade, LN2 or DI or something colder. That's not really practical for everyday use though.

The chip just overclocks depend on how well it's put together. No 2 chips are exactly the same. They may have the same steppings but there's always a little difference.
Not bad at all...
