During its Architecture Day 2021 event, Intel revealed that its upcoming Alder Lake CPUs will offer a 19% IPC increase over its Rocket Lake CPUs. This falls in line with the previous leak which suggested a 20% IPC boost.
According to the official slides, Alder Lake will support both DDR4 and DDR5. Moreover, it will support PCIe 5.0.
Intel Alder Lake will feature CPUs with up to 16 cores and up to 24 threads. 
Now as we’ve already said, Alder Lake will feature performance and efficient CPU cores. From the looks of it, the high-end CPU model will be the Intel Core i9-12900K. This CPU will feature 16 CPU cores, will support 24 threads and will have 30MB of L3 cache. Its efficient cores will boost up to 3.9 GHz (3.7 GHz all-core), while its performance cores will boost up to 5.3 GHz (5.0 GHz all-core).
Intel did not reveal any additional details, though we expect these new CPUs to come out later this year.
Stay tuned for more!
