Well the 8380 is only 10% faster single-threaded because of the large L3. Altra has higher ST perf than the 6330 with its smaller L3 (both 8380 and 6330 have the same 1T frequency of 3.4GHz). One can fit around 4 to 5 Neoverse N1 cores in one IceLake core, so you would expect a major ST performance advantage from such a huge core. Do you think 6.3% ST perf over the 2 year old 8280 counts as great progress?
