96-core server processor for cloud workloads
The Ampere Altra Max M96-28 is a 96-core, 96-thread processor running at a consistent 2.8 GHz frequency. It uses the LGA 4926 socket and is built on TSMC 7 nm FinFET technology. This CPU targets cloud-native computing environments requiring high core counts and predictable performance for scale-out workloads.
Eight-channel DDR4 memory and 128 PCIe Gen4 lanes
The integrated memory controller supports eight channels of 72-bit DDR4-3200 with ECC, accommodating up to 16 DIMMs and 4 TB total memory. The platform provides 128 lanes of PCIe 4.0 connectivity, with an optional 64-lane CCIX interface for multi-socket configurations. These I/O capabilities support extensive storage and networking expansion.
Suits hyperscale and enterprise deployments
This processor fits deployments prioritising core density, power efficiency, and consistent frequency scaling within a 132 W envelope. It is not suited for workloads requiring higher single-thread frequencies or platforms using different memory generations or socket standards. Buyers needing integrated graphics or alternative instruction sets should evaluate other architectures.

Questions about this item
What thermal solution does the M96-28's 132 W average power require for continuous operation?
The processor has a 132 W average power rating; the server chassis and cooler must be sized to dissipate that heat continuously.
At sustained load, which limit appears first — the 128 PCIe 4.0 lanes or the 8-channel DDR4-3200 memory bandwidth?
Memory bandwidth from the 8-channel DDR4-3200 controller typically saturates before the 128 PCIe 4.0 lanes become a bottleneck.
How much heat does the 96-core Altra Max M96-28 generate at its 132 W average power during all-day operation?
At 132 W average power the chip produces 132 W of heat; the system's cooling must remove that continuously.
