- 88 PCIe 5.0 lanes and four UPI 2.0 links for flexible I/O
- Rich set of accelerators and security features (QAT, DLB, DSA, IAA, TDX, SGX, TME)
- No SMT simplifies vCPU and licensing math
Cons
- No AVX-512 or AMX; unsuitable for HPC and AI training
- Low per-core performance and clocks (1.8–2.6 GHz)
- E-core only design can be slower for licensed or per-core-optimized software
- Higher list price than some EPYC Bergamo SKUs with similar core counts
- Fewer memory channels than Xeon 6900P/6900E series

Our Verdict on Each
A very high‑core‑density, efficiency‑focused server CPU that excels at throughput‑bound, scale‑out workloads, but it is not a general‑purpose performance leader and is limited to single‑socket platforms.
Best for: New 1‑socket server builds for cloud‑native microservices, 5G core, CDN, or scale‑out web workloads where core density and performance per watt are critical.
Read the full reviewA strong fit for dense cloud-native deployments that can leverage many modest cores rather than a few big ones, but a poor choice for workloads that depend on high single-thread performance, AVX-512, or AMX.
Best for: Building or refreshing a cloud-native or scale-out server farm where you can exploit 128 modest cores and prioritize energy efficiency and licensing simplicity over peak per-core performance.
