what makes an AMD FX-55 Better than a P4 3.6

I am a huge noob and I am just wondering, what makes a fx-55 so much better than say a leading P4 processor?
Thanks! :)
 
1. Its not universally better than the P4. Intel is superior at some things, AMD at others.

2. The generic answer to the question is "on die memory controller and unlocked multipliers"
 
A 3.6 GHz Pentium IV delivers 20% more power compared to the fastest AMD processors, but at 50% higher price. Well, the numbers are not completly right, but I think you know what I mean with that. :D

If you count the costs of the extremly high power consumption of the Pentium processor to the total price, the numbers are nearly correct. :rolleyes:
 
He's talknig about the power comsumption of the Athlon 64 although his number is for idle not load.
 
What are you talking about?

AMD FX-55 : Thermal design power = 105 W
Intel 3.60 GHz + : Thermal design power = 115 W
difference ~10%

Regardless, no one, with the exception of laptop users, buys a high performance CPU based on its power consumption.

Thermal Design Power isn't how much power the CPU consumes, it is the maximum power rating the heatsink must be able to dissipate
Intel said:
Thermal Design Power (TDP) represents the maximum amount of power the thermal solution is required to dissipate. The thermal solution should be designed to dissipate the TDP without exceeding the maximum Tjunction specification. TDP does not represent the power delivery and voltage regulation requirements for the processor.

Processor power dissipation simulations indicate a maximum application power in the range of 75% of the maximum power for a given frequency. Therefore, a system designed to the thermal design point, which has been set to approximately 75% of the maximum processor power would be unlikely to see the thermal control circuit active and experience the associated performance reduction.

The actual power consumption by the Athlon 64/P4 are as follows:

Yes, I realize that, didn't really feel like looking at benchmarks. I guess my question then would be where is that 210 W of power going if not out the heat sink? Is that the power the whole system (including chipset, drives, etc... I know the headings say system) requires? Probably a moot point, but I don't see how the power consumption of the CPUs can be much different is their thermal design powers are similar.
 
They say it is the power used for the entire system (videocard et all) the load test was non-video intensive.
