From the details released now about Alder Lake, the most significant seems to be that Intel has finally passed from 4 instruction decoders to 6 instruction decoders.
Alder Lake also now matches Zen 3 with 8 instructions fetched per cycle from the uop cache.
This was somewhat expected, because otherwise the increase in IPC announced by Intel would have been very hard to achieve, but now it is confirmed.
