1) Turin is supposed to be Q4, but GNR should also be out by then as well. This will be the closest Intel has been to AMD in competitiveness in this segment in years.
2) RPL instability sucks, but doesn't seem like too big deal. None of the analysts even bothered asking about it... Also, how is Zen 5 a killer? People are going to keep buying Zen 4X3D it looks like, considering Zen 5 doesn't even seem like it will beat Zen 4X3D in gaming lol. Intel's position compared to it's current position will only go up, even with ARL vs Zen 5X3D. The current gaming king is still Zen 4X3D, and when Zen 5X3D launches, will still be Zen 5X3D. So nothing changes there. The only change is that ARL is likely to be much better in power consumption vs AMD than RPL is vs AMD.
3) Again, this isn't anything new. AMD was a real contender even with Zen 4 as well. If anything, LNL seems like it will finally carve out a mobile niche where Intel finally can beat AMD.
In short, competition wise, Intel has no where to go but up esentially. What will hurt is the RPL instability, not because of costs directly attributed to this IMO, but because of how it will impact OEM relations.
