Questions about AMD's dual core Toledo.

[Silversierra]

Will the toledo core be like the venice core, ie, supports sse3, and four memory dimms?
Will the toledo require a monstrous power supply? If one amd a64 needs 18a 12v, does a dual core need 36a? Thanks.

the TDP for the toledo isn't that high, maybe 100w. Since they haven't lowered the voltage from 1.4v or so, 18-20A should be fine.

Jesus 80amps thats insane

Since when did one AMD or Intel chip require 18A on the 12V rail!? Last time i checked amd barely needs 7 for the chip alone and Intel ~12 or something. No where near 18.

No this will not double the maximum TDP.

Read the intel dual core article. That didn't even require double the amount of power.

I thought 18a+(edit:I mean on the 12v) was recommended for buying a psu for an amd64 system? I realize that all 18a aren't going to the cpu.

 

[Gamingphreek]

It doesn't seem like you know that the processor doesn't take up all 18amps. Essentially you are putting another processor in the system, so why would the entire systems power double?

Also 18a is considered minimum for a fully loaded system.

So if a a64 needs say 7a of the 18a, then that leaves 11a for everything else. So if you have a dual core it's 7a(per core) x2 = 14a, +11a for the rest = 25a. So will dual cores need 25a then? I assumed that dual cores would need more than double the power of a regular cpu. What does post 3 mean? 80amps for the top a64 dual core? Do you need 4psus to power that thing? I didn't realize that the processor uses so little of the 12v amperage. I assumed that it was using almost all of the 18a, or something because it seems like the cpu would use almost all of the power, but it looks like the fx55 uses less than 9a. Does the rest go to the cd and hard drives?

<Basic electronics>: P=IV </Basic electronics>

What that means is power equals current times voltage. So if your cpu takes 7 amps off the 12 volt rail and it runs at 1.4 volts then you can calculate the current it's drawing at 1.4V:

P = IV
P = 7 * 12 = 84Watts

84 = I * 1.4
I = 60 Amps

So an 84 watt CPU running at 1.4 volts draws 60 amps.

 

[Silversierra]

Ok, this is going to be a noob question but, if a cpu uses the 12v rail, how does the core run at 1.4v? How can the cpu be using 7 amps and 60 amps? I don't think any psu has 60 amps on any rail, so how does that work? Well, now I feel like a noob, but at least if someone explains it to me, I'll know more. Thanks.
