What the Xeon 6731E is
The Xeon 6731E is a 96-core and 96-thread server processor that launched in June 2024 for Xeon 6 dense clouds. Ninety-six Sierra Glen Efficient-cores without Hyper-Threading give 96 threads at 2.2 GHz base and up to 3.1 GHz boost. Cache is 96 MB. Processor base power is 250 W, which fits Birch Stream SP boards with server air cooling.
Ninety-six E-cores keep microservices together at modest clocks. DDR5 with ECC feeds the die from board memory. PCIe Gen5 lanes serve NVMe and networking, with UPI for dual-socket nodes.
Throughput clouds fit here. The 2.2 GHz base sustains parallel jobs where lower-base parts dip. Buyers who need higher base for latency should take the 2.4 GHz 6740E with the same 96 cores instead, since this 6731E prioritizes efficiency.
Socket and motherboard compatibility
The 6731E fits LGA 4710 on Birch Stream SP boards with 250 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 follows 1 DIMM per channel at top speed. Power tuning is available where enabled.
E shoppers compare 96-core parts on base and turbo. The 6731E trails the 6740E slightly on both. 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 standard. Services plus caches should be sized together. Matched sets are preferred.
PCIe Gen5 lanes serve storage and networking. Fixed splits require manual checks.
Cooling is server 250 W with vendor-qualified air. No retail cooler applies.
Upgrade paths
LGA allows moves within the vendor list, such as to higher-base E twins. Memory and NVMe can also grow.
A working 6731E serves dense clouds for years.
