Anyone see the nethash difference on XMR? On nanopool from 138Gh to just 33Gh after fork..... how many asic bricks do you think are out there now?
I think its too early to tell
https://bitinfocharts.com/comparison/monero-hashrate.html#3mCurrently all we are seeing is just variance.
If its anything like the fork that happened 6 months ago, it will take a few days for the difficulty to adjust and then we can make an analysis.
One thing is certain. The Tahiti's (R9 280X GPUs) all decreased their speeds by 33%, so will be some drop there alone.
I noticed all of my pre-maxell cards took a big hit.
My D8P test rig's hashrate went from ~1470h/s to ~940H/s
The only cards really "propping" that machine up now are a 1070 and a RX560.... the rest took a major hit in hashrate compared to CN7.
