These CPUs could be worthwhile if they had at least quad-channel memory. Unfortunately, the early leaks suggest that they still have dual channel. I didn't realize the importance of memory bandwidth until I switched from Skylake-X to Raptor Lake, and discovered that many programs actually run slower. I have now switched to M4 max (8 channels) and is satisfied, despite having only 16 cores.
Intel Nova Lake CPUs are scheduled to release sometime in late 2026. Intel is reportedly going all-out with up to 52 total cores and even 144 MB of extra last-level L3 cache. However, RedGamingTech has repored that there could be an even more monstrous Nova Lake SKU which doubles the 144 MB last-level cache.
