Description

Frequency-optimized 32-core Zen 4 server CPU tuned for latency-sensitive and per-core performance workloads such as trading apps, databases, and application servers. Delivers high base clocks with strong single-thread response, while retaining 12-channel DDR5 bandwidth and PCIe 5.0 I/O for low-latency storage and networking. Includes SEV-SNP and modern ISA extensions for secure, accelerated compute. Suitable for 1P or 2P SP5 servers that prioritize clock speed and responsiveness.

Features

High base clocks for low-latency, per-core sensitive workloads
- Robust 32-core capacity for mixed compute and virtualization
- 12-channel DDR5 and PCIe 5.0 for balanced bandwidth and I/O
- SEV-SNP for confidential computing and data-in-use protection
- Zen 4 ISA features including AVX-512, VNNI, and BF16

Warranty

All products sold by XS Network Tech include a 12-month warranty on both new and used items. Our in-house technical team thoroughly tests used hardware prior to sale to ensure enterprise-grade reliability.

All technical data should be verified on the manufacturer data sheets.
