Question ryzen 5 2600 double power consumption than i5 4570. Why?

[bobalazs]

i5 config is : Asrock H81M-VG4 i5 4570 2x8gb ddr3 1600 mhz

intels cpu is 84w tdp,

amd config is: Gigabyte GA-b450M S2H Ryzen 5 2600 2x8 Gb ddr4 3200 Mhz

amd's is 65w.


the mobo+cpu+memory changed only and also added 2 more 12 cm case fans.

the b450 chipset supposedly eats about 5W.
he B450 chipset runs a lower powered integrated controller which reduces the idle power draw by just under 2 W, from 6.8 W to 4.8 W.

ddr4 has lower power consumption than ddr 3 supposedly

The Intel configuration's power consumption was 39W idle intel power picture
The Amd's was 76W Amd power picture
Everything running on full auto, no OC, changed clocks to default fix 3400 Mhz, no difference.
power consumption in bios 84w bios power consumption picture

Aida64 FPU stress test

Intel 88W intel aida fpu
Amd 123W amd aida fpu

Furthermore, when i left everything on auto in bios, raised the CPU clocks to 37.75, I got 170W from the meter by benchmarking with linpack only. https://logout.hu/dl/upc/2019-08/110225_explorer_2019-08-03_04-34-00.thumb.png

Maybe bios isn’t stable yet just wait for bios update and see what happens

This motherboard is not a new issue. its b450. it already has multiple bios out. It is updated to the one before last bios, because of issues with newest one.

I mean bios doesn’t give the right information still not stable

What do you mean, the power measurements were done using a power meter. whatever bios does, it can not explain the excess 40-50w power consumption.
