EDIT:
there are 2 types of RX 560 card from sapphire:
11267-00 --> 90W edition
11267-01 --> 45W edition
Maybe the SAD edition (the 11267-01) has only 14 compute units...
No, 45W version is the one without external PCI-E connector, so
its restricted to draw max 75W (from board) while 90W one can use
max 150W (75W from motherboard and 75W from PCI-E 6-pin connector)
Radeon RX 560 Radeon RX 460
Shaders 1024 vs 896
Compute Units 16 vs 14
TMUs 64 vs 56
it s maybe restricted to 75w but it use more
i have 5x rx460 4G msi with no pci-e power and with dual mining the ring use 560w (no cpu load) with stock setting
so you can say each gpu use 100w
i just try to undervolt but cannot do much it crash very fast with gpu at 1210mhz
i also change the traps to 1375 but cannot overclock the memory, i tested lot of traps, try to increase the memory more than 1750 it crash
but even with memory at 1750 with 1375 trap it s 1.2 mh faster on eth @ 12.5 mh
