Well, if they can turbo at 5 GHz while consuming nearly half as much power as the equivalent Intel part... it sure does sound like something that I might buy.
The article body shows the AMD chip slightly behind the i9. The chart just after it shows two different figures - "pre-brief" it's behind, "on stage" it's ahead. Not a huge margin in any case.
Power consumption was significantly better. I'd say they're still ahead.
