Slightly OT, but I'd love to see that data. So far everything I've read shows that even a strait 8400 will, if allowed
, continuously draw well over 100Watts during synthetic benchmarks (see Tom's review
, specifically the Prime95 with AVX enabled test loop).
Hi. I borrowed a watt meter from my friend to check what it draws from the wall. Also I use Core Temp software to monitor the internal data. By default there are a lot of things enabled for power saving in BIOS and Windows (10 is very much recommended as it use the most advanced latest Speed Shift/Speed Step technologies), and it is what 99.9% of users should use. I have a Mini-ITX Asrock z370 board, 16 gigs of RAM and 2 SSDs, plus USB audio interface (RME Babyface Pro) and a smartphone charging. At idle it draws about 25-27 watts from the wall. On a processor level at idle it draws about 2 watts. With disabled C-states, disabled core parking, and minimum limit for the clocks @ 2000 MHz (settings I need for audio work) it draws 6-7 watts at idle and Internet browsing (processor only). Watching some video adds about 2-3 watts extra (10 watts overall).
I'm not a big synthetic tests expert, I've run something in Prime 85 and also there is a "stress" button in the CPU-Z software. To me they do about the same thing. All cores are loaded 100%. Internally the software shows 46.6 Watts for processor package in this case (Core Temp utility). So, from the wall it'll be, add 40 to 27 (idle from the wall) - so about 67W from the wall at full synthetic(!) load. In reality with what I do (working with audio) I stay at about 10-12 watts internally 98% of time, with occasional load up to 20 watts for some short period audio rendering, files unpacking, etc. The processor temps stays at about 37-40 C for now (max at 51 C), with usual comfortable spring temperatures outside. Although it'll be very hot soon in the summer where I live. I use HDPlex H3 V2 Passive case, making an extensive review right now.
ADDED: sorry, as I said, I'm not a testing expert, just checked with the Prime85, set it to small FFT this time (I don't know what it is, also did not find where are the AVS settings and what it is) - so yes, 85 Watts on a processor level this time, which means slightly over 100 Watts from the wall.
