The increased SRAM density is a big thing. As process sizes shrink, logic does get smaller but cache memory generally lags behind and does not shrink proportionally.
That’s one reason why CPU caches are still so small and haven’t changed much in over a decade.
This change should enable larger L1 and L2 caches, which is important on modern CPUs that spend much of their time waiting for data to come back from main memory.

- thunderbird120 3y agoDon't get used to it. N3E has no SRAM density improvement over N5 and its TSMC's "real" N3 node since N3B (Base) is prohibitively expensive for all but the very richest customers. N3B is such an economic dead end of a node that TSMC doesn't even have an upgrade path to transition N3B designs to N3E.
