INTEL Xeon 6434H 3.70GHz CPU
The Intel Xeon Gold 6434H is a 20-core, 40-thread processor from the 4th Gen Intel Xeon Scalable family (Sapphire Rapids microarchitecture, launched 2023), aimed at buyers building or refreshing dual-socket-capable enterprise servers. With a 2.50 GHz base clock, 3.60 GHz max turbo frequency, and 205W TDP, it suits virtualization hosts, general-purpose compute, and storage/controller workloads. Note that this CPU requires an FCLGA4677 socket platform with DDR5 support, so verify motherboard compatibility before ordering.

Good to know
- Compatibility: The FCLGA4677 socket is shared only with 4th/5th Gen Xeon Scalable platforms — older LGA4189/LGA3647 boards are not supported, and full memory capacity depends on the server platform’s DIMM slots.
- Family positioning: As a Gold-tier Sapphire Rapids part, it sits in the mid-range of the 4th Gen Xeon Scalable lineup, offering a strong core count and PCIe Gen 5.0 / DDR5 features without Platinum-tier pricing or power requirements.
- Buying tip: Since the board must explicitly support Sapphire Rapids (BIOS/firmware dependent), confirm your server chassis, VRM, and cooling can handle the 205W TDP, and pair with DDR5-4800 modules across all 8 channels for full bandwidth.
