Confirmed: AMD will follow the path of Intel.
However, there will be one major difference from Intel: if the “blue” ones combine cores of different architectures in their CPUs (high-performance Golden / Raptor Cove and energy-efficient Gracemont), then AMD will have all the cores on the Zen 4 architecture, only conditionally small ones will receive less cache and will work at lower frequencies, but they will consume less energy. One of the Phoenix CPUs was previously lit up on the network – 2 of it are two “large” cores and four “small” ones. But this is just one of the options, and besides, it is clearly not the most powerful.
The premiere of Phoenix processors is expected at CES 2024 or a little later – in the second half of 2024.
