More than the dates, which have been leaked pseudo-confirmed by several differnt people and sources, I'm more interested in pricing leaks. One of them I saw recetly put the 7700X at around $300 and the 7600X at around $200. That would be really good, but at the same time, it paints* a rather sad picture for AMD: they know they can't compete under 12 cores, which would be reasonable given how Intel is positioning Raptor Lake SKUs using Alder Lake as a reference. The i5 this generation is going to be, more than likely, another great performer in the price to performance category considering the whole platform cost. AMD will need to have a very reasonable entry to AM5 in order to get traction, I'd say.
All of this to say: I'm happy initial leaks point to low-ish entry price points. This is what competition brings!
Regards.
