Use Case
Altra Max is built for predictable, deterministic throughput rather than peak single-thread speed: every core is single-threaded with its own 1 MB L2, so there is no SMT contention and performance scales linearly. M128-30 is the top bin, typically found in cloud and CDN nodes, Arm-native CI farms and dense edge racks where 128 independent vCPUs per socket plus 4 TB of DDR4 capacity matter more than the highest clock.
