#1 - RDNA3 needs to bring a big improvement in RT performance, because the first iteration has been a bit meh (roughly on par with Nvidia's first iteration, but too far from Ampere to be able to compete). The extra 2x RT cores that will come from the extra CUs will surely improve the end performance, but they also need to improve the performance of the RT cores themselves. I hope they'll be able to do it, but the result may still end behind Nvidia's next GPUs.

Yea as long as RDNA 3 can close the gap, I think it will be good enough for most people. As long as they don't have another situation where a 3070 is able to compete with a 6900XT in very demanding RT games, it will be fine. If RDNA 3 is 10-15% behind Nvidia, then that's close enough for the majority of people. Especially as Super Resolution should be out by then.

The problem is that we don't know how big of an improvement will Lovelace be to Ampere in RT so, even if AMD manages to double or triple its performance, things could end in the same awkward situation.

I think (and I know that it's easy to say something like this for someone that doesn't know shit), that they should double thei RT hardware per CU. With RDNA2 they have 1 RT core per CU, and that has proved to not be enough. They should increase that to 2 RT cores per CU, plus the extra CUs from the new chiplet design. Pack in the extra refinements and improvement that come from a second iteration, and then we would be onto something.

Yea it's also quite hard to tell where the bottleneck is for AMD. The main difference at a high level between Nvidia and AMD's implementation is that Nvidia's RT cores does both Intersections and BVH traversal where as RDNA 2's Ray Accelerators only does Intersections and leaves the BVH traversal to the CUs. Now the main benefit with leaving it up to the CUs is that on consoles, developers can fine tune it but on PC as both Direct X Ray Tracing and Vulkan Ray Tracing doesn't allow such fine tuning as of yet, there doesn't seem to be any benefit. But no one actually knows what benefit it would even have even if the PC Apis would allow it since even on consoles, you have ps5/series X which are similar to 2070 Super and 2080 performance in Raster but in heavy RT games, they are more like 2060 Super even though consoles have low level advantages.

But regardless of which, I think the next jump for PC hardware is gonna be one fap worthy jump. Lets just hope that the price doesn't increase by much and the miners/scalpers won't interfere to this extent.
