What GFlops did Linx show?
Part of the power to drive the CPU will also be across the regulators and the efficency of the power supply. For instance if the CPU were drawing 100W then that might require 110W or more at the wall.
Here is a link to my test results so far. I've tested the chip from 3333MHz to 4256MHz.
LinX performance was a relative constant as I increased the multiplier, increasing from 64.312GFlops @ 3333MHz to 78.9442GFlops @ 4256MHz
The purpose for isolating the CPU power consumption is for understanding how increasing Amerpage affects Max VID according to the datasheet linked below.
My understanding of table 2-8 on page 25 is that as Amperage "Icc (A)" increases (i.e., the more you overclock) the lower your Max VID "Vcc MAX" tolerance becomes lower. This is being done for the purpose of understanding the theoretical maximum "smart" overclock that yields performance benefits without exceeding specifications on table 2-8.
To explain in more detail,
The end result is a power profile for my CPU Overclock. I'll explain.
According to page 25, figure 2-8, of this data-sheet...
As Amperage "Icc (A)" increases (i.e., the more you overclock)
The lower your max tolerable voltage is beginning at whatever your Max VID is (in my case 1.375v), decreasing linearly 5A*(-0.004v)
...that is, if I'm reading it correctly (and I'm on Intel forum asking the same stuff to find out).
Once I know a fairly accurate Amperage usage for my CPU at a given overclock, I can use that information to find out what the Vcc_MAX is at that voltage.
If this can be accomplished there are numerous benefits.
- Finally separating where the line is drawn between a "golden chip" and a "crappy chip" or some "average chip" based on hard numbers.
- People will have solid evidence for how far they can reasonably expect to push their CPU without fear of degradation or risking failure because this work can be replicated for every Intel CPU type.
Here are my tests so far.
Again the question is quite simple. How accurate do those amerpage readings look for the i7 980x?
