Xeon Gold 5420+ 28-core server processor
The Intel Xeon Gold 5420+ is a 28-core, 56-thread server CPU built on 10 nm Sapphire Rapids architecture. It operates at a 2.0 GHz base frequency with a 4.1 GHz maximum turbo speed and includes 52.5 MB of L3 cache. The processor fits the LGA 4677 socket and has a 205 W thermal design power.
Upgrade path from older Xeon platforms
This processor supports DDR5 4400 memory across eight channels with a maximum capacity of 4 TB. It provides 80 lanes of PCI Express 5.0 connectivity and supports two-socket scalability. The jump is worth it for workloads that need higher core counts, faster memory throughput and expanded I/O bandwidth compared to previous dual-socket generations.
Suited for dual-socket compute nodes
The 5420+ targets virtualisation hosts, database servers and high-performance compute clusters that benefit from 56 threads and large memory capacity. Buyers who need single-socket operation only, lower power envelopes or fewer than 28 cores should evaluate other SKUs in the Xeon Gold or Silver range.

商品問答
Will this LGA 4677 socket processor fit my server board?
The CPU uses the LGA 4677 socket and has a 205 W TDP, so the motherboard must provide that socket and a cooling solution rated for at least 205 W.
What is the correct way to install this CPU and what step is often missed?
Align the notches on the processor with the socket keys, lower it gently, then secure the retention mechanism; the step often missed is applying fresh thermal paste before mounting the heatsink.
When will I need to replace the thermal paste on this 28-core processor?
Thermal paste should be replaced whenever the heatsink is removed or if temperatures rise above normal; under typical server loads it lasts several years before reapplication is needed.
