Product description

Intel Xeon Platinum 8558P: 5th Gen Emerald Rapids CPU with High Cache Density and DDR5-5600

The Intel Xeon Platinum 8558P is a 5th Gen Intel Xeon Scalable processor based on the Emerald Rapids architecture, delivering 48 cores, 96 threads, a 2.7 GHz base frequency, turbo speeds up to 4.0 GHz and 260 MB of L3 cache. It is designed as a drop-in upgrade for existing LGA4677 platforms, providing higher performance and efficiency compared to 4th Gen Sapphire Rapids while keeping the same socket and platform infrastructure.

Emerald Rapids focuses on increasing performance per watt and improving effective throughput for datacenter workloads. Compared to the previous generation, 5th Gen Xeon Scalable processors offer higher clock speeds, larger last-level caches per core and support for faster DDR5 memory, which together provide better performance in AI, HPC, analytics, networking and storage-oriented tasks.

The Xeon Platinum 8558P supports eight channels of DDR5 memory with speeds up to DDR5-5600 on suitable configurations, enabling higher memory bandwidth than Sapphire Rapids and improving scaling for memory-bound workloads. This benefits in-memory databases, real-time analytics systems, distributed caching layers and large microservice platforms, where both latency and throughput of memory access are critical.

With 260 MB of shared L3 cache, the 8558P offers significantly more cache capacity than comparable 4th Gen models. The enlarged L3 cache helps keep hot data close to the cores, reduces trips to main memory and improves performance in workloads with irregular access patterns, large working sets or heavy contention on shared structures, such as complex analytics queries or heavily loaded application servers.

Emerald Rapids retains support for 80 lanes of PCIe 5.0 per socket, allowing the 8558P to drive high-performance NVMe storage, fast network interfaces, SmartNICs, DPUs, FPGAs and GPU accelerators. For operators standardizing on the Eagle Stream platform, this makes it possible to upgrade to 5th Gen CPUs and benefit from higher performance and cache density without redesigning the server hardware around a new socket.

The “P” suffix indicates targeting of cloud and IaaS workloads, where predictable performance, consolidation efficiency and power characteristics are important. In practice, the Xeon Platinum 8558P fits well in roles such as high-density virtualized compute, cloud-native platforms, large enterprise application stacks and analytic services that benefit from higher per-socket performance and cache capacity.

For datacenter operators already invested in LGA4677, the Xeon Platinum 8558P provides a straightforward path to boost node performance and efficiency, while keeping compatibility with existing boards, memory configurations and chassis designs.

Intel Xeon Platinum 8558P Technical Specifications Analysis

Based on the provided technical data, the Intel Xeon Platinum 8558P processor demonstrates a number of significant advantages in its segment:

  • Clock Frequency Leadership: Among the high-performance models of the Platinum family, the 8558P features the highest base frequency at 2.7 GHz. This is substantially higher than flagship models with more cores (for example, the 8592+ and 8490H only offer 1.9 GHz). Higher frequency ensures superior performance in applications critical to single-core speed.
  • Efficient Cache Volume: The L3 cache capacity is 260 MB, which is more than double the figures of previous generation models (such as the 8490H with 112.5 MB or the 8468 with 105 MB). This minimizes latency when processing large datasets.
  • Optimal Balance of Specifications: With a 48-core / 96-thread configuration, the processor reaches a Turbo Boost frequency of 4.0 GHz. Compared to the 8468 model, which has the same core count, the 8558P offers higher frequencies and a significantly larger cache while maintaining the same thermal envelope (TDP 350W).
  • Per-Core Performance: The combination of architectural improvements and high frequency allows the 8558P to prevail over competitors in mixed workload scenarios, where not only computing density but also system response speed is essential.

Conclusion

The Intel Xeon Platinum 8558P is the most balanced solution in the lineup for high-load systems. It outperforms competitors through a unique combination of high base frequency (2.7 GHz) and expanded L3 cache (260 MB). This processor is ideal for data centers and enterprise environments requiring maximum performance from each core when performing complex computing tasks and working with databases.

Product FAQ

Intel Xeon Platinum 8558P is equipped with 48 physical cores and supports 96 threads. This provides the high computing density required for modern server infrastructures and virtualization.
