Intel Core 7 253PQE socket: LGA 1700
The Intel Core 7 253PQE uses the LGA 1700 socket. It is the 125 W ten 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 7 253PQE is
The Intel Core 7 253PQE is the 125 W ten core of Bartlett Lake, Intel's Core Series 2 embedded family launched in the first quarter of 2026. Ten Performance-cores with Hyper-Threading produce 20 threads, 33 MB of Intel Smart Cache is shared across them, and Efficient-cores are absent. Base frequency reaches 3.5 GHz, the highest base clock in the Bartlett Lake stack, while Performance-cores turbo to 5.5 GHz and Thermal Velocity Boost peaks at 5.7 GHz. The process is Intel 7 and the tray recommended customer price is $409.
Ten cores at a 3.5 GHz floor suit consolidation roles where a single box absorbs work that once spread over several smaller nodes. Virtualized control functions, on premise inference services and storage front ends all benefit from high sustained clocks more than from extra threads that would sit idle. The 33 MB cache keeps the ten cores fed, and uniform core design removes asymmetric scheduling from certification testing.
Compared with the twelve core 273PQE above it, the 253PQE gives up two cores and 3 MB of cache while matching the 125 W class and most of the clock behavior. Sites that license software per core or that simply never fill twelve cores can bank the saving without changing boards, cooling or memory. Time Coordinated Computing and Time Sensitive Networking support carry over across the family for deterministic installations.
Socket and motherboard compatibility
The chip uses the FCLGA1700 package for LGA 1700, and industrial firmware is mandatory. W680 and Q670 class boards form the usual base, with R680E, Q670e, H610E and H610 designs also documented around the family. Because 125 W stresses regulation and thermals, the board must be rated for the PQE class explicitly rather than merely for the socket.
Retail boards cannot help regardless of chipset. ASRock confirmed its whole consumer LGA 1700 lineup, Z790 models included, will stay without Bartlett Lake BIOS support, calling these processors industrial parts for embedded PCs and similar systems. An unsupported processor stops a board before POST, and no update will change that status. Consumer LGA 1700 configurations therefore end with the 14th Gen.
Choose W680 class hardware where ECC memory and workstation style management matter, or Q670 class hardware for administered fleets. Either way the exact 253PQE SKU must appear on the published support list. The Socket vs chipset: what decides whether a CPU works guide covers the chipset and BIOS interplay behind such lists.
Memory, PCIe and cooling
Memory runs at DDR5 up to 5600 MT/s or DDR4 up to 3200 MT/s on two channels to 192 GB, with ECC available for unattended operation. DDR4 board variants protect earlier memory investments, and DDR5 variants raise throughput for caching and buffering layers. Slot type never changes after purchase, so memory generation is decided with the board.
I/O comes from 20 processor lanes, sixteen PCIe 5.0 plus four PCIe 4.0, joined by eight DMI 4 lanes toward the chipset. Fast fabric cards, accelerators and NVMe arrays all hang off those lanes in edge servers. Intel UHD Graphics 770 with 32 execution units at 300 MHz to 1.65 GHz drives four displays to 8K on DisplayPort for local consoles.
Thermally the 253PQE behaves like its twelve core classmate: plan for 125 W of continuous heat plus boost headroom inside the cabinet. Tray supply means the heatsink is the integrator's choice, mounted on the 78 mm LGA 1700 pattern explained in the CPU cooler compatibility by socket guide. Validate temperatures under the real workload, since brief benchmark runs understate cabinet heat soak.
Upgrade paths
Later moves within the family need no new board when support lists align. The 253PQE can step up to a twelve core for heavier consolidation or down to the 65 W and 45 W ten core SKUs for cooler sites, keeping memory and chassis. Each direction still requires regulator headroom and an updated support entry.
Retail desktop parts remain a separate world despite the shared socket. The Intel Core i5-14400 runs on consumer 600 and 700 series boards with Raptor Lake Refresh firmware, which never intersects industrial Bartlett Lake firmware. Plan embedded and desktop estates independently.
A full platform exit lands on a newer embedded socket with fresh board and memory validation, located through the How to find your CPU socket type guide. Industrial supply lifetimes are measured in years, so the 253PQE will commonly outlast the planning horizon it was bought for.
Frequently asked questions
What socket does the Intel Core 7 253PQE use?
It uses LGA 1700, marked FCLGA1700 in Intel documents. Only industrial boards with firmware support start with it.
Will the 253PQE work in a consumer Z690 board I already own?
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 3.5 GHz base clock the highest in the family?
Yes, 3.5 GHz is the highest base frequency Intel lists across the Bartlett Lake stack, including above the twelve core 273PQE at 3.4 GHz. Sustained all core jobs benefit most from that floor.
What memory does the 253PQE support?
Boards carry DDR5 slots rated to 5600 MT/s or DDR4 slots rated to 3200 MT/s, two channels to 192 GB with ECC. The slot type is fixed per board, so memory must match the board ordered.
