Hi!
I have recently bought AMD Threadripper 3970x and tried to compare rendering times with my 2990wx config.

So configurations are:

1.
CPU: AMD threadripper 2990wx
COOLING: Coolermaster masterliquid ML360 TR4 edition
MOB: Gigabyte x399 Aorus pro
RAM: 64Gb Corsair Vengeance LPX DDR4
GPU: ZOTAC AMP! Extreme 1070 8 Gb
DISK: WD SN750 m.2 500 Gb
PSU: EVGA supernova 750 G3 750 W

2.
CPU: AMD threadripper 3970x
COOLING: Coolermaster masterliquid ML360
MBO: Asus ROG STRIX TRX40-E gaming
RAM: 64Gb Corsair Vengeance LPX DDR4
GPU: ZOTAC AMP! Extreme 1070 8 Gb
DISK: ADATA SX8200 Pro 512 Gb
PSU: Thermatake Toughpower Grand RGB 850W Gold


Test scene was archexteriors 34 scene 10. Render was started out-of-the-box. No tweaking.

2990WX rendered it in 61 mins, while 3970x finished it in 19 mins.

As far as I know 3970x is not 3x faster than 2990wx.
I think that something is not OK with my 2990wx.
Does anyone has experience with 2990wx?
What could be wrong with 2990wx config?
