Intel Xeon D-1746TER socket: BGA 2227

What the Xeon D-1746TER is

Released in February 2022, the Intel Xeon D-1746TER targets network appliances and edge systems with 10 cores and 20 threads. Sunny Cove cores run 2.0 GHz base with up to 3.1 GHz turbo, backed by 15 MB of Intel Smart Cache. The 67 W rating sets board cooling and power delivery.

Memory support covers DDR4-2667, 3 channels, up to 384 GB, ECC supported. Three channels feed compact network functions and edge containers, and ECC corrects single-bit errors during continuous duty. Sixteen Gen4 lanes from the SoC serve NICs and NVMe on small boards. The How to find your CPU socket type guide covers board wiring for edge systems.

The 1746TER suffix marks this chip for the extended-temperature embedded range for edge boxes. Makers validate it on specific appliance boards, so the board CPU list names the exact suffix. Builders who need more cores on the same package use Intel Xeon D-1732TE, while fewer cores cut power for small edge nodes.

Socket and motherboard compatibility

The D-1746TER fits BGA 2227 on single socket network or edge boards with soldered retention. The chip is soldered and cannot be replaced. Board lists must name the exact suffix for qualification.

There is no multi-socket option and no socketed variant. Memory channels, NIC wiring and expansion follow the appliance design, not a retail motherboard list. Larger boards on BGA 2579 serve dense appliances, while BGA 2227 serves compact edge nodes.

Memory, PCIe and cooling

DDR4-2667, 3 channels, up to 384 GB, ECC supported. Matched DIMMs hold the rated speed across all populated channels.

PCIe Gen4 lanes from the SoC wire high-speed NICs and NVMe, 16 lanes for compact edge boards. PCH Gen3 lanes serve board devices behind them.

Cooling belongs to the appliance maker across the 67 W band with front-to-back airflow. No boxed cooler exists. Paste service follows the maker manual for the large soldered package.

Single socket platform

Every Xeon D in this stack runs single socket only with no interconnect links between processors. The Intel Xeon D-1746TER pairs 10 cores and 20 threads with 3 channels of DDR4 ECC memory on one board, so throughput scales with clocks and channels rather than with socket count. Appliance makers validate the exact suffix on their board and firmware before volume orders.

Sixteen Gen4 lanes from the SoC wire high-speed NICs and NVMe storage, with PCH Gen3 lanes behind them for board devices. The 67 W rating of this SKU decides heatsink size and airflow direction in the appliance chassis. Because the chip solders down, core count, memory size and TDP are chosen once at order time for the life of the box.

Upgrade paths

On BGA 2227 the moves run along core count within the same board class, up to flagships such as Intel Xeon D-1732TE where validated. Core growth needs no board change when the maker lists the part.

Beyond the series the replacement is a whole appliance on newer platforms. The CPU cooler compatibility by socket guide explains when a platform change pays off.
