- 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 paradigm-shifting Xeon processor that trades single-thread speed for unparalleled core density and efficiency, perfectly tailored for the modern cloud data center.
Best for: Building new cloud data center racks for containerized, microservices, or VDI workloads where core density and power efficiency are paramount.
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.
