What the Xeon 6980P is
The Xeon 6980P is a 128-core and 256-thread server processor that Intel launched on September 24, 2024 at 13955 dollars for Xeon 6 cloud flagships. One hundred twenty-eight Redwood Cove Performance-cores with Hyper-Threading give 256 threads at 2.0 GHz base and up to 3.9 GHz boost with 3.2 GHz all-core turbo. Cache is 504 MB of Smart Cache. Processor base power is 500 W, which needs top-notch liquid cooling.
Three 598 sq mm compute dies plus two I/O dies form the large AP package. Twelve-channel DDR5-6400 or MRDIMM-8800 up to 3 TB with ECC feeds 128 cores plus accelerators. Up to 96 Gen5 lanes per CPU with 6 UPI links at 24 GT per s connect sockets, GPUs and NVMe. Two-socket operation doubles threads to 512 per node.
Flagship clouds and HPC nodes fit here. One hundred twenty-eight cores keep the largest parallel jobs in one socket. Buyers who need fewer cores with higher base should take 96-core parts such as the Intel Xeon 6972P instead, since this flagship prioritizes thread count.
Socket and motherboard compatibility
The 6980P fits LGA 7529 on Birch Stream boards with 500 W delivery and 2S support. A BIOS that lists Granite Rapids-AP is required. The FCLGA7529 package uses the BR1A carrier in a 104.5 by 70.5 mm body.
Memory is DDR5-6400 or MRDIMM-8800 in 12 channels up to 3 TB with ECC. Speed Select Core Power and Turbo features tune per workload where enabled. Population is 1 DIMM per channel at top speed.
Flagship shoppers compare AP tops on cores and cache. The 6980P leads on both. The Socket vs chipset: what decides whether a CPU works guide covers server vendor lists.
Memory, PCIe and cooling
DDR5-6400 or MRDIMM-8800 in 12 channels up to 3 TB with ECC is the flagship standard. Huge datasets plus VMs should be sized together. Matched dozens are preferred.
PCIe gives 96 Gen5 lanes per CPU plus UPI links for GPUs, NVMe and networking. Fixed splits mean accelerator plans must match the manual.
Cooling is server 500 W with liquid to handle 128 cores. No retail cooler applies to tray server supply.
Upgrade paths
LGA allows flagship moves within the vendor list, with cooling to match. Memory and NVMe can also grow to 3 TB and arrays. BIOS must support the target.
A working 6980P leads clouds for years. E-core Sierra Forest on similar platforms trades per-core speed for density.
Frequently asked questions
What socket does the Xeon 6980P use?
It uses LGA 7529 on Birch Stream server boards with 500 W delivery. A BIOS that lists the part is required.
How many cores does the Xeon 6980P have?
One hundred twenty-eight cores and 256 threads at 2.0 GHz base and up to 3.9 GHz boost, with 504 MB of cache at 500 W.
What memory does the 6980P support?
DDR5-6400 or MRDIMM-8800 in 12 channels up to 3 TB with ECC.
Can the 6980P run in dual-socket boards?
Yes, within AP on the same board where power, cooling and BIOS allow. Two-socket operation is supported.
