Intel Xeon Gold 6434 server processor

The Intel Xeon Gold 6434 is an 8-core server processor built on 10 nm Sapphire Rapids architecture. It delivers 16 threads at a 3.7 GHz base frequency with a 4.1 GHz max turbo. Designed for dual-socket platforms, it suits enterprise workloads requiring strong single-thread performance.

LGA 4677 socket compatibility

This processor fits only the LGA 4677 socket used by Intel Xeon Scalable platforms. The socket choice dictates motherboard and platform selection; no other socket will accept this chip. Verify your board supports the 195 W thermal design before installation.

4 TB DDR5-4800 across eight channels

The integrated controller drives eight channels of DDR5-4800 memory up to 4 TB total capacity. This bandwidth serves large in-memory databases and virtualisation hosts well. Workloads exceeding 4 TB or needing more than eight memory channels will require a different processor tier.

Questions about this item

What does the 3.7 GHz base clock mean for sustained workloads on this Xeon Gold 6434?

The 3.7 GHz operating frequency is the guaranteed all-core speed under the 195W thermal design, so sustained server tasks run at that rate without throttling as long as cooling meets the spec.

How does the PCIe 5.0 interface with 80 lanes limit expansion on this processor?

PCIe 5.0 provides up to 80 lanes directly from the CPU, capping total bandwidth for add-in cards, storage and networking at Gen 5 speeds without needing a chipset bridge.

What does the LGA 4677 socket require for physical installation of this 6434?

The LGA 4677 socket needs a compatible server motherboard with an independent retention mechanism and a cooler rated for at least 195W TDP, as no cooling device is included.
