Last week Intel has confirmed that Panther Lake is the code name of their desktop CPUs that will be launched in 2025 and which will be made using the Intel 18A CMOS process.
Therefore this is no longer a speculation.
It can be assumed that these are the first CPUs that will implement the 256-bit subset of the AVX10.2 ISA, finally extending the coverage of AVX-512 to all Intel products, but with the restriction to 256-bit registers and operations.
Panther Lake will be preceded by Lunar Lake for low-power mobile devices, either in late 2024 or in early 2025.
Before that, there will be Arrow Lake S for desktops and Arrow Lake for laptops. Despite the single name, these 2 implement different instruction sets and they will be made with different manufacturing processes, Intel 20A for Arrow Lake and an undisclosed process for Arrow Lake S (which might be made at TSMC, according to rumors, because it needs bigger tiles than what would be possible in Intel 20A).
While Meteor Lake seems to be just a shrink of Raptor Lake, which will have a much better performance only due to the greater energy efficiency provided by the Intel 4 process and due to the much better GPU made at TSMC, Arrow Lake is expected to introduce a new improved CPU microarchitecture, which is supposed to compete successfully with Zen 5.
