I think after launch when we get some reports on sustained clocks it will be right back to 33%.Yes, I'm the one who needs to cope with a 15% difference in compute throughput (with a significantly faster back-end) instead of your dear promised 33%.
Salt much?
Don't worry, it'll get better with time.
Github Inquisition team constantly mocked my posts suggesting over 2GHz clocks. Their whole bullying constantly revolved around the 33% compute throughput difference.
I can get you the quotes, when I get the time. Assuming goalposts aren't moved after I do.
