What is the actual power usage? Will that be more efficient than RX 580?

Just receive my RX VEGA 56 (Thanks LDLC.com and the discount Sapphire RX VEGA 56 (405€) )


Fresh install win 10 + last driver, after a few tests, I got 35 MH/s for something like 150W

What I can tell :
AfterBurner do not like Vega
WattMan is not really friendly
Voltage control seems not to work great

I'll try to improve that and test blockchain drivers are they worth it ?

36 Mh/s at 135 watts isn't too bad. I think that's the best efficiency I've seen from Vega yet. It will be interesting to see if that number can get up to 40 Mh/s at the same power rate with newer versions of miners and/or drivers.

I've got 44.2mhs at 160watt from the wall. But it is worse then monero and dual in current prices

yeah for now only wattman can droping wattage,
flash it with 64 bios, it would help 43,7mhs/150-160watt,

Confirmed it works !!!

hashrate on vega 56 43mh

so far the 17.8.2 BUT the hashrate jumps around a lot...starts off at 43.1 and then goes down ...so im not sure if its the driver, wattman or my PSU at the moment. Going to try the blockchain drivers next .

GPU clock 1000
Mem clock 1100

UPDATE

So i changed to the drivers 17.9.1 and with claymore 10 and im getting 43.7mh(Vega Sapphire 56) at a total system wattage of around 220. That includes an I3-7320  and 2x 2tb hard drives so i think that is pretty good.

What i did

1. Install fresh copy of win 10
2. Installed 17.9.1 drivers
3. Using wattman i changed the GPU clock to 1000 and the Mem clock to 1100 hit apply
4. Then i lowered the power limit to 10% and hit apply( lowering the power limit is not actually lowering the wattage at the wall)
5. Then i took the power limit back to default ...hit applied and rebooted the PC

Hope this helps someone

66watts

UPDATE...

the 43.7 was for Expanse

Just tried the same settings with ETH 38.5
