Cloud Native 80-core processor

The Ampere Altra Q80-30 is an 80-core server processor built on TSMC 7 nm FinFET technology for cloud native computing environments. It runs at a consistent 3.0 GHz frequency with single-threaded cores and supports 64-bit workloads. The LGA 4926 package delivers 128 lanes of PCIe 4.0 connectivity and optional 64-lane CCIX for multi-socket configurations. Average power draw is 161W.

Installation notes for LGA 4926

Installation requires a compatible LGA 4926 socket and server board with adequate 161W cooling capacity. The processor integrates an 8-channel DDR4-3200 memory controller supporting up to 16 DIMMs at 2DPC for a maximum of 4 TB with ECC. Misaligned pin contact or insufficient VRM phases are the most common issues during bring-up. BIOS must support the Ampere Altra family for proper initialisation.

Suited for scale-out cloud workloads

This processor suits hyperscale and enterprise deployments that need high core counts, predictable frequency and extensive PCIe 4.0 I/O for scale-out services. Buyers who require integrated graphics, desktop socket compatibility or workloads that depend on higher single-thread boost clocks should look at alternative architectures. The 80-core design targets throughput-oriented cloud native applications rather than legacy single-threaded code.

Questions about this item

How can I confirm the Ampere Altra Q80-30 is running at its consistent 3.0 GHz frequency after installation?

Monitor CPU frequency readings in the operating system or BIOS; all 80 cores should report a steady 3.0 GHz under load, matching the processor's consistent frequency design.

What is included with the AC-108021002 processor and what must be purchased separately?

The processor itself is supplied; a compatible LGA 4926 motherboard, DDR4-3200 ECC memory modules (up to 16 DIMMs), and a cooling solution rated for 161 W must be sourced separately.

Which Ampere Altra model should I choose if I need 80 cores and 128 PCIe 4.0 lanes?

The Q80-30 provides exactly 80 cores, 3.0 GHz consistent frequency, and 128 lanes of PCIe Gen4, distinguishing it from the 32-core, 64-core, and Altra Max variants.
