5800X3D looks excellent for those that 8 cores are enough for. Sadly, many want/need more cores in 2022. AMD would have been onto a huge winner if they released 5900x/5950x with the 3D cache technology, as this would save people having to replace motherboard & RAM, since Zen4 offers no DDR4 controller.
Looking forward to reviewers that test 12900KS, along with 6400Mhz+ DDR5. Makes sense to test both platforms at their best available performance, regardless of performance. Using DDR4 on a 12900k when faster DDR5 is available is not that useful to determine overall performance.
