Athlon 4, 20% decrease in power, that is way not enough.

[Degenerate]

I am not a geek but i have noticed people complaning about the heat dissapation of the Tb's. They get hot and very hot. Does power consumptions have to do with this directly?

1600*0.8 = 1280mhz That means that a 1.6 will have the same amout of power usage as the current 1.3??

I barely read the article because i got to go so somewhere. I might be wrong. mabey the Athlon 4 has got other stuff.

If it is true, that meas the Athlon 4 can only go up to about 1.8? (if the tb's go to 1.4)..

tha is just a thought, gotogo.

Edit again: dame you are right Travis, i changed it to 1.3 instead of 1.4 as well.

 

[TravisBickle]

your maths are bad. anyway your intel licking is well known. give it a rest.
gotogo

 

[Degenerate]

my maths is fine, i menat to type 0.8 instead of 0.2

looks like you are going nowhere faster than I am. the above is what you posted originally.

He's right though.

Assuming the current Athlon is going to stop being produced at 1,4GHz, due (in no small part), to heat restrictions then the Palomino core with 20% less heat will make 1400/0.8 = 1.75GHz.

hmmm
is that 20% less heat caused by -
a reduction of voltage (1.4v now right?)
OR the core improvements?

maybe they save 20% from the new core, and even more from lower voltage?
or its probably overall savings and i just read the artical too fast lol

I read the article too quickly also. I didn't know that there would be a quiz afterwards.

Dynamic power of the CMOS circuit can be estimated by the following formula:
Pdyn = aCV^2F, where a is the activity factor, C is the circuit capacitance,
V-the supply voltage, F- frequency. Other than the dynamic power (consumed due to switching), there is leaage power.

The Fmax depends on the &quot;speed paths&quot;, and power disspation is not an indication of Fmax
(provided there is an adequate cooling). I do not have any information about the &quot;speed
walls&quot; of K7, but I'd like to here some guesses. I cannot write my own for obvious reasons.

What was the old default voltage? 1.75v? If so then that is an EXACT 20% drop... I hope this isn't the 20% drop in heat they were talking about...

Power = I V = I^2

R right? So 20% drop in voltage = 20% drop in heat output if current remains the same.

So assuming we ALSo get a 20% drop in heat due to the better transister design etc then we get 0.8*0.8 = 0.64 --> 36% reduction in temperature.

1.4/.64 --> 2.2 GHz, not too shabby....

<< The Athlon 4 takes the same Thunderbird core and further optimizes the core by using more optimized transistors for various portions of the core. When you are dealing with the 37.5 million transistors that make up the Athlon 4, such optimizations can result in quite a bit of power savings. According to AMD, these improvements to the Athlon 4 result in a 20% decrease in power use compared to an equivalently clocked Athlon using the Thunderbird core. >>


From what Anandtech has posted, it seems to me that the core optimisations result in the power saving, which then, according to AMD, result in the 20% power savings. So my original calculations (now edited for TravisBickle) still holds from what I have read.

I don't think its wise to start a Flame-war already (guys!)

You just can't wait to grabb at an opportunity.

I think we should all consider the AT post, not as a review (unfortunatlly), but an info, which I would have put this way &quot;The Athlon 4 is almost ready!&quot; and thats it.

This 1/8 review (almost just a picjust got the AMD fans (including me) all exited for nothing(yet) and the Intel fans got their flamtrowers ready (also all for nothing). Now all is trying to attack/defend with as little as that (about 20% decrease in SOMTHING). THATS NOT ENOUGH FOR WAR, you just have to wait.

Degenerate,

Are you taking into account the throttling down of the CPU due to Power Now? Reducing the volage to 1.2V.
