Product identity

The Ampere Altra Q32-17 is a 32-core server processor operating at a consistent 1.7 GHz. It uses the LGA 4926 socket and is built on TSMC 7 nm FinFET technology with an average power draw of 40W.

Suitability

This processor suits cloud-native deployments that need high core counts, predictable frequency scaling and 128 lanes of PCIe Gen4 connectivity. It is not suited for workloads requiring higher per-core clock speeds or instruction-set architectures other than the 64-bit Arm implementation used here.

Deciding specification

The consistent 1.7 GHz frequency across all 32 cores determines whether this part matches a given workload. Buyers should verify that their software scales effectively at this fixed clock rate before selecting the Q32-17.

Questions about this item

Will the TSMC 7 nm FinFET silicon or the LGA 4926 socket require periodic maintenance or replacement?

The processor is a fixed silicon component with no moving parts; the LGA 4926 socket is mounted on the server board and neither item has a scheduled replacement interval.

Under sustained load, does the 40 W average power envelope or the consistent 1.7 GHz frequency become the limiting factor first?

The processor maintains its 1.7 GHz frequency within the 40 W average power envelope, so the power budget is the design limit that governs sustained operation.

What noise, heat or power characteristics appear when the 32-core chip runs all day at its 40 W average power?

At 40 W average power the thermal output is modest for a 32-core server CPU; a standard server heatsink and fan assembly handles the heat with typical data-centre airflow and acoustics.
