Sounds like a solid deep dive. The M2’s L1 is still pretty tight at 128 KB per core, but the L2 is noticeably larger than the M1’s, which gives those tight loops a bit more headroom before hitting the higher‑latency L3. The real kicker is the new inter‑core cache coherence protocol – it reduces the false‑sharing penalty, so if you’re working on multi‑threaded data structures that share a lot of small state, you’ll see a tangible hit to throughput. Just keep an eye on the cache‑line eviction patterns; the M2’s larger L2 can still thrash if you’re moving big vectors across cores. Overall, it’s a step up, but the real gains come when you can shape your data layout to fit those cache lines.
