History
The Xeon 6980P represents Intel’s effort to reclaim leadership in the high‑core‑count server CPU segment. After AMD EPYC pushed past Intel’s 28–40‑core Xeon Scalable generations, Intel responded with the chiplet‑based Granite Rapids architecture. The 6900P series, led by the 6980P, is the first Xeon to reach 128 full P‑cores in a single socket, matching AMD’s core counts and restoring competition at the top of the HPC and AI server market.
</br>Intel’s own benchmarks and independent reviews show Granite Rapids delivering substantial performance lifts over the prior Emerald Rapids generation, especially when paired with MRDIMM memory and AMX‑enabled software. The platform also introduces CXL 2.0 and a large set of integrated accelerators, signaling Intel’s strategy to differentiate via on‑package specialization rather than raw core count alone.
However, the high 500 W TDP and premium pricing have kept the focus on large data center deployments where the throughput and feature set justify the cost.
Improvements over Previous Generation
- 128 P‑cores vs 64 in 8592+, roughly 2× core count.
- 12‑channel DDR5/MRDIMM vs 8‑channel DDR5‑5600.
- 96 PCIe 5.0 lanes vs 80, plus CXL 2.0.
- Integrated AMX, DLB, DSA, IAA, QAT accelerators vs more limited acceleration in prior gen.
