Yeah, the 7600, 7700 XT and 7900 XT were badly priced at launch. But the 7800 XT and 7900 XTX were great.
Showing false benchmark results at launch is really poor, but people should know better than to believe marketing hype, and look for real reviews before buying. That doesn't affect the end product in any way, imo.
RT didn't improve because they basically used RDNA 2's RT engine. They spent all their R&D on chiplets and improving raster, neither of which paid off really well. But that still didn't make the end products bad, just not as much better than RDNA 2 as we'd hoped. Now, they're doing the opposite: they're trying to improve RT and the video engine while only doing minor fixes on raster, and backtracking on the chiplet design. I'm curious if it'll pay off, this is why I'm disappointed that we didn't get more detail.
