FAQs

Q: When should I choose the 8454H over higher core count models?
A: Choose 8454H when per‑core performance and frequency are favored, such as for certain databases, licensing models, or latency‑sensitive apps.

Q: Is memory speed capped at 4800 MT/s?
A: Up to DDR5‑4800 is supported; actual speed depends on DIMM type and population.

Q: Can I use this with another CPU model in the same server?
A: No. Dual‑socket systems require identical CPUs.

Q: Does it support AI acceleration?
A: Yes. Intel AMX, AVX‑512, and DL Boost are supported for AI/analytics workloads.

Q: What socket does it require?
A: LGA4677, as used by 4th Gen Xeon Scalable platforms in UCS X‑Series.
