What the Xeon 6780E is
The Xeon 6780E is a 144-core and 144-thread server processor that launched in June 2024 as the Sierra Forest flagship for dense clouds. One hundred forty-four Sierra Glen Efficient-cores without Hyper-Threading give 144 threads at 2.2 GHz base and up to 3.0 GHz boost. Cache is 108 MB. Processor base power is 330 W, above 250 W siblings for top E-core clocks.
The higher 2.2 GHz base and 3.0 GHz turbo lead E-cores on response while keeping 144 threads. DDR5 with ECC feeds the die from board memory. PCIe Gen5 lanes serve NVMe and networking, with UPI for dual-socket scale. The 108 MB cache holds large working sets across many threads.
Flagship density with the fastest E clocks fits here. One hundred forty-four threads at top E speed cover the largest fleets per socket. Buyers with 250 W limits should take the 6766E with the same 144 threads instead, since this 6780E needs stronger cooling for the last 0.3 GHz.
Socket and motherboard compatibility
The 6780E fits LGA 4710 on Birch Stream SP boards with 330 W delivery. A BIOS that lists Sierra Forest is required. The FCLGA4710 package uses a server carrier.
Memory is DDR5 with ECC in 8 channels. Population is 1 DIMM per channel at top speed. Power capping tunes per workload where enabled.
Flagship E shoppers compare the two 144-core parts on 0.3 GHz base and turbo. The 6780E leads the Intel Xeon 6766E on both for 80 W more power. The Socket vs chipset: what decides whether a CPU works guide covers server lists.
Memory, PCIe and cooling
DDR5 with ECC in 8 channels is the flagship E standard. Huge fleets should be sized with bandwidth in mind. Matched sets are preferred.
PCIe Gen5 lanes serve storage and networking. Fixed splits require manual checks.
Cooling is server 330 W with vendor-qualified air or liquid. No retail cooler applies.
Upgrade paths
LGA allows flagship moves within the vendor list, with cooling to match. Memory and NVMe can also grow.
A working 6780E leads E density for years.
