Lenovo ST650 V3 Xeon 6426Y Server

The Lenovo ST650 V3 is a rack-mount server system built around an Intel Xeon Gold 6426Y processor. It delivers 16 cores and 32 threads at a base frequency of 2.5 GHz with a maximum turbo of 4.10 GHz. The CPU provides 37.50 MB of L3 cache and fits the LGA-4677 socket with a 185 W thermal design power.

Suited for dense compute workloads

This configuration suits environments that need high core counts in a standard rack form factor, such as virtualisation hosts or database nodes. It is not intended for buyers who require integrated graphics output or single-thread optimisation above all else. Organisations needing a tower chassis or lower power envelope should evaluate other platforms.

Sustained 185 W operation under load

Under continuous multi-threaded load the processor operates at its 185 W rating, so cooling and power delivery must handle that steady draw. The 16-core design maintains consistent throughput across 32 threads without relying on short burst behaviour. Rack airflow and adequate power distribution are essential for stable long-running tasks.
