Intel Core 5 211TE socket: LGA 1700

What the Core 5 211TE is

The Intel Core 5 211TE covers the 45 W point of the 10-core Bartlett Lake embedded lineup under Core Series 2. Six Performance-cores with Hyper-Threading plus 4 Efficient-cores yield 16 threads, 20 MB of Intel Smart Cache is shared, and clocks run 1.7 GHz P-core base with turbo to 4.8 GHz alongside 1.3 GHz E-core base to 3.4 GHz boost. Intel lists the part as an embedded vertical segment SKU on FCLGA1700, built on Intel 7.

That low power with a real P-core complex suits fan-assisted cabinets, compact vision boxes and telecom shelves where sustained draw stays modest but bursts must clear quickly. The 1.7 GHz P-core base keeps the 45 W envelope in reach for small enclosures, while single-thread bursts to 4.8 GHz handle interactive spikes without a larger budget.

Against the 65 W Intel Core 5 211E twin above it, the 211TE trades base clocks for a 20 W lower envelope at identical core counts. Against the 45 W 14-core Intel Core 5 221TE above it, the 211TE trims 4 E-cores for lighter cells. ECC support and long-life supply suit sites that qualify once and deploy for years. See Socket vs chipset: what decides whether a CPU works for why chipset series plus BIOS revision together decide board fit.

Socket and motherboard compatibility

Packaging is FCLGA1700 for LGA 1700 in a 45.0 × 37.5 mm package, and only industrial firmware brings the chip up. Typical carriers are W680 and Q670 class boards, joined by R680E embedded designs documented for the family. Because board vendors qualify power classes individually, the 211TE must appear by name on the support list rather than being assumed from socket fit.

Consumer hardware is generally fenced off by BIOS policy for this embedded family. Retail LGA 1700 lineups target 12th to 14th Gen desktop parts, and Bartlett Lake embedded SKUs belong to industrial PCs, embedded motherboards and module products. Without processor initialization data in firmware, a retail board stops before POST. Desktop builders on LGA 1700 stay with the 14th Gen.

Pick W680 class boards for ECC memory at remote sites and Q670 class boards for centrally managed fleets. The Socket vs chipset: what decides whether a CPU works guide shows why chipset series plus BIOS revision together determine which processors a board accepts.

Memory, PCIe and cooling

DDR5 to 5600 MT/s or DDR4 to 3200 MT/s is supported on two channels to 192 GB, ECC included, with the board fixing the memory generation. DDR4 keeps legacy industrial kits productive, while DDR5 widens headroom for buffering and display tasks. Capacity planning should reserve ECC UDIMMs where W680 class boards expose them.

Twenty processor lanes split into sixteen PCIe 5.0 and four PCIe 4.0, with chipset DMI linking extra board I/O. That layout hosts a network interface or frame grabber beside NVMe storage in compact machines. Intel UHD Graphics 730 with 24 execution units serves control displays and HMIs without a discrete card.

Cooling follows the industrial heatsink list for the 45 W class on the 45.0 × 37.5 mm heat spreader. No cooler ships with the tray part. Firmware power limits can cap draw below the default where a sealed cabinet demands it, at some cost in sustained clocks.

Upgrade paths

On the same socket, the path up from the 211TE starts with the 65 W Intel Core 5 211E twin for higher sustained clocks on LGA 1700 industrial boards where cooling allows. The 45 W 14-core Intel Core 5 221TE beside it adds E-cores at the same 45 W class. Each move needs a BIOS that already supports Bartlett Lake.

The step down to the 45 W 4-core Intel Core 3 201TE trims to P-cores only for single-service boxes. A move to BGA 1264 Atom Amston Lake is a different soldered platform with far fewer lanes for sealed micro nodes. That change replaces board, memory and cooling from scratch.
