I would wait for the reviews to land around the 20th. based on the performance of the 5600x vs the Intel 12400, the 5600 non X will be very close in price to performance to the 12400 at the same price. but you may find better motherboard options and lower electricity costs with the AMD chip. Intel alder lake boards are stupid expensive.
I don't think it's worth waiting for Ryzen 7000, unless you plan to spend about double the price of an Intel 12400
What seems to be happening here, is AMD will reserve the new silicon wafers for their midrange (starting at 5600x) and high-end chips (5950x) and their replacements in Ryzen 7000 when they go to 5nm. Then as they prepare for the next generation to come out, they will then use the 1 gen older silicon for lower-end products, like in this release.
It makes sense when they cannot buy enough of TSMC's latest wafers to meet demand across the whole product range.
