It would not only be a nice boost to system performance, but it would sure fire up the PS5 hype train to off the rails levels. With rumors saying the XBSX runs a little hot, yet quiet, and MS employee's basically indirectly confirming by saying, 'that's normal as per design so don't worry', you can't help but wonder if XBSX has much headroom to do the same if MS wanted to respond to a move like that. Not to mention XBSS.
If the next gen polls are any indication, PS5 has so much of a lead, that SNY really doesn't need to bother with a move like that. Though views could change between now and launch depending on what both companies still have up their sleeves. I doubt either company would change specs even if they could after launch, so it's soon or never. Again, I'm not overly optimistic, but I think it's likely to remain unnecessary for SNY even if some minor competitive moves are made.
I don`t think PS5 will have any issues selling all available consoles on the first year. And Sony won`t touch this if it isn`t 100% safe for them.
This does sound more like an amd driver issue thou. This could just be out of sonys hand and are waiting for amd to improve things on their end or toghether. If it's fixed in a year and there's nothing they could do about it, I see no reason for them not to increase clocks in the year that its available. It cost them nothing amd gives them a leg up.
