What the Xeon 6746E is
The Xeon 6746E is a 112-core and 112-thread server processor that launched in June 2024 for Xeon 6 dense clouds. One hundred twelve Sierra Glen Efficient-cores without Hyper-Threading give 112 threads at 2.0 GHz base and up to 2.7 GHz boost. Cache is 96 MB. Processor base power is 250 W, which fits Birch Stream SP boards with server air cooling.
One hundred twelve E-cores keep highly parallel 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.
Scale-out web and caching tiers fit here. The large thread count covers connections per socket. Buyers who need higher base for latency should take 96-core parts with 2.4 GHz base instead, since this 6746E prioritizes density over clocks.
Socket and motherboard compatibility
The 6746E 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 112-core parts against 96-core and 128-core neighbors on base and power. The 6746E sits between on threads. 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. Connection-heavy services should be sized with memory bandwidth in mind. 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 128-core E parts. Memory and NVMe can also grow.
A working 6746E serves dense tiers for years.
