Cloud-native 128-core server processor
The Ampere Altra Max M128-26 is a 128-core, 128-thread processor built on TSMC 7 nm FinFET technology for cloud-native workloads. It operates at a consistent 2.6 GHz frequency across all single-threaded cores without turbo fluctuations. The LGA 4926 socket supports 8-channel 72-bit DDR4-3200 memory with ECC for up to 4 TB total capacity. It delivers 128 lanes of PCIe 4.0 connectivity with optional 64-lane CCIX for multi-socket scaling.
Sustained 133 W performance profile
Under continuous load the processor maintains its 2.6 GHz clock speed at an average power draw of 133 W, avoiding the frequency drops common in burst-oriented designs. Each core provides 1 MB of L2 cache and 64 KB of L1 instruction and data cache, giving predictable latency for parallel tasks. The 16 MB system-level cache is shared across the 128 cores, supporting throughput for containerised and micro-service deployments. Dynamic power management and voltage-droop detection help keep output steady during extended runs.
Upgrade from lower-core Altra or Altra Max SKUs
This model replaces 32-core, 64-core, 80-core or 96-core variants when workloads need the full 128 cores and 128 PCIe 4.0 lanes in a single socket. The jump is worthwhile for hyperscale and enterprise environments that require maximum thread density and memory bandwidth without adding a second processor. Buyers who need fewer cores or less I/O bandwidth can select a smaller Altra or Altra Max SKU instead.

商品問答
How much heat does the 128-core 2.6 GHz processor produce under sustained load?
The chip has an average power rating of 133W, so cooling must handle that continuous thermal output.
What memory modules are required for the 8-channel DDR4-3200 controller?
You need DDR4 DIMMs with ECC; the platform supports up to 16 DIMMs at two per channel for a maximum of 4 TB.
Will my existing PCIe 3.0 add-in cards work with the 128-lane PCIe 4.0 interface?
Yes, PCIe 4.0 slots are backward compatible, so PCIe 3.0 cards will operate at their native 3.0 speeds.
