HPE Xeon Gold 6442Y 24-core server processor

The HPE P49599-B21 is a 24-core Xeon Gold 6442Y processor designed for HPE ProLiant servers. It runs at a 2.60 GHz base frequency with 48 threads and 60 MB L3 cache. This new server CPU targets data-centre workloads needing high core counts and 64-bit processing capability.

Socket LGA-4677 platform constraints

The processor fits the LGA-4677 socket and carries a 225 W thermal design power. Cooling and power delivery must handle this envelope within the specific server chassis. The 4 GHz overclocking speed noted by the manufacturer represents a maximum turbo frequency dependent on workload, thermals and platform firmware limits.

Upgrade from lower-core Xeon Silver or Bronze models

Replacing a lower-core-count Xeon Silver or Bronze CPU with this 24-core Gold model adds significant parallel throughput for virtualisation, databases and compute clusters. The jump is worth it when thread count and cache capacity bottleneck current workloads, and the server board supports the LGA-4677 socket with adequate power and cooling headroom.

Questions about this item

Is the 24-core 2.60 GHz version the right choice for my workload compared to other capacities?

The 24-core configuration delivers 48 threads at a 2.60 GHz base frequency with 60 MB L3 cache, suited for multi-threaded server tasks.

What does the 4 GHz overclocking speed mean once the processor is installed in a server?

The 4 GHz figure represents the maximum turbo frequency achievable under thermal and power headroom; sustained speeds depend on the system cooling and 225 W TDP limits.

What does the Socket LGA-4677 interface cap in practice for memory and I/O?

The LGA-4677 socket connects the processor to the platform; supported memory speeds, channel counts and I/O lanes are defined by the server motherboard and chipset.
