Hi folks!
Here’s a more exotic config and some AMD results:
Machine: 2x Intel Xeon e5440 with 40Gb of ddr2 RAM and 2x rx480 8gb with modified ROMs (better timings for dagger-hashimotto, 20% higher TPD limit, 21.5% VRAM overclock).
1.45 GPS per GPU@90W and
0.1GPS for all CPU 8 cores@around 150W load (rather pointless 
)
Running Ubuntu 18.04, Linux 4.15.0-33-generic with amdgpu-pro drivers, the cards run 1288Mhz GPU and 2150Mhz VRAM. GPU clocks exhibit little impact on power consumption and solution rate, 1.1GPS, 80W at 910Mhz minimum power.
Tested cards with 4Gb of VRAM do not work except with the cuckatoo algo, so RX570 with overclocked RAM does 0.1GPS and pulls a bit over 30W wilst having left no more resources to mine other algorithms.
