Description

The Xeon Gold 6434H is a high-frequency variant tailored for the most latency- and jitter-sensitive workloads. With 8 cores at a 3.7GHz base and a substantial cache, it prioritizes per-core throughput while leveraging DDR5-4800 and PCIe 5.0 on the LGA4677 platform. The 195W power profile suits performance-focused 1U/2U servers with adequate cooling.

Features

- High-frequency 8-core design for latency-critical applications
- 3.7GHz base clock with large cache for consistent per-core throughput
- DDR5-4800 and 8-channel memory architecture for bandwidth
- LGA4677 platform with PCIe 5.0 device support

FAQs

Q: How does the 6434H differ from the 6434?
A: The H-suffix indicates a high-frequency bin targeting the lowest latency and highest per-core performance; verify exact clocks/features in your server vendor’s CPU list.

Q: What workloads benefit most?
A: Trading, real-time analytics, API gateways, and per-core licensed databases/services that demand high sustained clocks.

Q: What memory configuration is recommended?
A: ECC DDR5 RDIMMs up to 4800 MT/s, following your platform’s population and speed rules for optimal bandwidth.

Q: Do I need special cooling?
A: Yes, ensure your chassis and heatsink meet the thermal requirements for a 195W high-frequency processor.
