I never really thought about how much the power delivery system on the motherboard could impact the power usage. I assume that the systems have been designed to be efficient in a certain voltage range and current draw so they could be quite inefficient if they get pushed to the limits.

Although it seems like it would be the other way around, the Z390 board should be more capable than the Z170 since it was designed for a 8/16 processor.

My board has very similar power delivery as the Maximus X Formula.

ASUS ROG motherboard Product Manager, Andrew Wu, confirmed with Bit-Tech that Intel's previous-gen Z270 chipset is compatible with Coffee Lake CPUs, with Wu saying it would require a small change "depending on Intel's decision". Bit-Tech asked if it was a "physical limitation", but Wu replied saying "Not really. It [the power delivery] makes a little bit of difference, but not much". Then the big question: "so if you wanted and Intel let you, you could make Z270 compatible", to which Wu replied: "Yes, but you also require an upgrade from the ME (Management Engine) and a BIOS update. Intel somehow has locked the compatibility". There you have it folks, Intel is locking users out of upgrading to Coffee Lake on their current Z270 boards, by forcing users to buy a Z370 motherboard.

no need, was just curious. That's what? a 15% difference in power draw between two 9900k chips at the same voltage and frequency on the same benchmark?

Don't know that I've seen such a wide variation like that before.

We still dont know that for sure.




WannaBeOCer You must use the same version of Prime95 as Toms, there are large variations between versions. We also dont know whether they used LargeFFT or SmallFFT. Typically SmallFFT gives the largest power draw. We also need to know how Toms averaged their power consumption and do the same. Power draw will drastically change depending on the specific FFT size being calculated. Since it can easily take 5-10 minutes per set of calculations simply running 8 minutes and saying "this is what I got" isnt correct. And lastly we need to find out whether Toms and your machine have the same security fixes in place or not. The security fixes will dictate whether other work is being done to flush systems between processing so load wont be as high.
Until we know all the details this still isnt good enough of a control test.


edit: looks like Toms uses SmallFFT:

I'm not sure which version of Prime95 he's using when testing the 9900k. I'll re-run it using SmallFFT but I'm pretty sure that will just use less power than Large.

Power consumption measurements are always a bit tricky, but as long as the 12V supply (EPS) readings and the sensor values ​​of the power supply of the mainboard plus voltage transformer losses plausibly coincide, everything is fine. Therefore, we again rely on the pure package power to avoid possible influences from the motherboard. The values ​​of the PWM controller are really very reliable if taken as averages over a period of a few minutes.

im sorry but i highly doubt a 9900K is pulling just 219W in small ffts on P95 avx it just not true

thats a 8700K small ffts load it just jump straight to over 200w+

in the same condition that 9900K will close to 300w+

What's your package when you run LargeFFTs on Prime95 AVX? Since according to Prime95 that consumes the most power. How about you replicate my previous screen shot?

no, small ffts do..

large ffts is a walk in the park on p95 XD

large ffts will use like 2/3rds power of what small ffts will consume

thats almost 250w on 24k try 4/8k XD

Sorry I ran Small FFTs that says maximum, you can check my screen shot and see I ran smallFFTs.
