Intel Core 5 223PQE socket: LGA 1700
The Intel Core 5 223PQE uses the LGA 1700 socket. It is the 125 W eight core of the Bartlett Lake embedded range for industrial and edge systems, and consumer 600 and 700 series boards have no BIOS support for it, so it runs only on industrial boards that list it.

What the Core 5 223PQE is
The Intel Core 5 223PQE tops the eight core Bartlett Lake set with a 4.0 GHz base frequency, the highest base clock Intel lists anywhere in the family. Launched under Core Series 2 in the first quarter of 2026, it combines eight Performance-cores and Hyper-Threading for 16 threads with 24 MB of Intel Smart Cache and no Efficient-cores. Performance-core turbo reaches 5.3 GHz with Thermal Velocity Boost to 5.5 GHz, all inside a 125 W envelope on Intel 7. Tray recommended customer price is $319.
A 4.0 GHz floor on eight cores serves latency sensitive control loops that cannot wait for boost. Motion control, high frequency inspection triggers and deterministic networking stacks run their hot paths at guaranteed clocks, and the 125 W budget holds those clocks under full load. Peak behavior trails the twelve core flagships, but per core responsiveness leads the stack.
Eight cores also keep software licensing and validation costs below ten and twelve core parts where those models charge per core. The full 32 execution unit UHD Graphics 770 stays on board for consoles, unlike the cut down graphics of the value 213 pair. Time Coordinated Computing and Time Sensitive Networking support completes the real time picture.
Socket and motherboard compatibility
FCLGA1700 packaging fits LGA 1700, and industrial firmware alone authorizes startup. W680 and Q670 class boards are the expected carriers, with R680E, Q670e, H610E and H610 designs also documented across the family. A 125 W eight core needs regulation and cooling rated for the PQE class, not merely for the socket, so verify both on the support list.
Consumer boards are barred by firmware policy rather than mechanics. ASRock confirmed its retail LGA 1700 lineup including Z790 will receive no Bartlett Lake BIOS support, classing the family as industrial parts for embedded systems. Without processor initialization data the board halts before POST, and no later update supplies it. Retail configurations on this socket end with the 14th Gen.
Real time deployments favor W680 class boards where ECC memory guards long running control state, or Q670 class boards for managed fleets. Either class must name the 223PQE explicitly. The Socket vs chipset: what decides whether a CPU works guide covers how chipset series and BIOS level combine into support.
Memory, PCIe and cooling
Memory runs DDR5 to 5600 MT/s or DDR4 to 3200 MT/s on two channels to 192 GB with ECC. High base clocks raise sustained memory traffic, so DDR5 pays off more clearly here than on lower power siblings. DDR4 variants still serve refresh builds that reuse installed modules.
Sixteen PCIe 5.0 lanes plus four PCIe 4.0 lanes from the processor, with eight DMI 4 lanes to the chipset, host fast I/O cards and NVMe in compact controllers. Intel UHD Graphics 770 with 32 execution units at 300 MHz to 1.65 GHz drives four displays to 8K DisplayPort for local supervision screens.
Thermal planning treats this as a 125 W continuous part in an industrial cabinet. Tray supply includes no cooler, and heatsink selection follows the 78 mm LGA 1700 pattern in the CPU cooler compatibility by socket guide. Validate under the real control workload at worst case ambient, since synthetic bursts understate cabinet heat.
Upgrade paths
Downward and lateral moves inside the family suit validated boards. From the 223PQE, the 65 W 223PE and 45 W 223PTE preserve the eight core layout at lower heat, while the value 213 pair trims cost where graphics and memory ceilings allow. Ten and twelve core SKUs add threads for consolidation. Every move rechecks the support entry and cooling.
Retail desktop parts belong to a different firmware universe. The Intel Core i5-14400 runs Raptor Lake Refresh code on consumer 600 and 700 series boards, which cannot start a 223PQE and cannot be started by it. One package, two platforms: stock spares separately.
Platform exit in due course means a newer embedded socket with board and memory qualified together, found through the How to find your CPU socket type guide. Long industrial availability keeps that decision years out for most installations.
Frequently asked questions
What socket does the Intel Core 5 223PQE use?
It uses LGA 1700, marked FCLGA1700 in Intel documents. Only industrial boards with firmware support start with it.
Can I install the 223PQE in a consumer Z790 board?
No. ASRock confirmed its consumer LGA 1700 boards, Z790 included, will not receive Bartlett Lake BIOS support. The chip fits the socket physically but the board will not start without the matching firmware.
Is the 4.0 GHz base clock the highest in the family?
Yes, 4.0 GHz is the highest base frequency in the Bartlett Lake family, above the 3.5 GHz of the ten core 253PQE and the 3.4 GHz of the twelve core 273PQE. Latency sensitive control loops benefit most.
What cooling does the 223PQE need?
A 125 W continuous load needs an industrial heatsink and cabinet airflow rated for full duty at worst case ambient. No cooler ships in the tray, so thermal design belongs to the system builder.
