Intel Core 9 273PTE socket: LGA 1700
The Intel Core 9 273PTE uses the LGA 1700 socket. It is a 12-core Bartlett Lake embedded processor 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 9 273PTE is
The Intel Core 9 273PTE is the 45 W twelve core of the Bartlett Lake embedded range, which Intel lists under Core Series 2 with a first quarter 2026 launch. All twelve cores are Performance-cores with Hyper-Threading, so the chip carries 24 threads with 36 MB of Intel Smart Cache and no Efficient-cores on the die. Base frequency is 1.4 GHz and Thermal Velocity Boost reaches 5.5 GHz, with Performance-cores rated to 5.3 GHz. Intel builds the part on Intel 7 and prices tray quantities at a $549 recommended customer price.
A processor without Efficient-cores behaves differently under load than a hybrid desktop chip, and that difference is the point for edge racks and networking appliances. Every thread runs on an identical core with the same instruction throughput, which keeps latency predictable when edge and industrial workloads scale across all cores. Intel equips the family with Time Coordinated Computing and Time Sensitive Networking support alongside long term servicing contract Windows support, both aimed at installations that stay in service for years.
Against its twelve core siblings the 273PTE trades base clock for thermal headroom. The 65 W 273PE starts at 2.3 GHz and the 125 W 273PQE at 3.4 GHz, while this part holds the same 36 MB cache and the same boost class inside a 45 W envelope. Systems with limited cooling budgets are the natural home, provided the board maker validates the part.
Socket and motherboard compatibility
The package is FCLGA1700, so the chip seats in the LGA 1700 socket mechanically. Mechanical fit is only the start: Bartlett Lake runs solely on industrial boards whose firmware lists it, commonly built around W680 and Q670 class chipsets, with R680E, Q670e, H610E and H610 variants also named for the family. Buy the board and the processor as a validated pair and confirm the exact SKU on the board support list before ordering.
Consumer boards stay out through firmware. ASRock confirmed it has no plans to add Bartlett Lake support across its consumer LGA 1700 lineup including Z790, describing the parts as industrial silicon for embedded PCs and similar equipment. Without initialization code and microcode in the BIOS, a board will not complete POST even though the chip seats correctly. That leaves the 14th Gen desktop range as the last consumer generation on the socket.
Industrial vendors validate each SKU separately because power delivery and cooling differ between a 45 W part and its 125 W sibling. W680 class boards add ECC memory support for unattended sites, while Q670 class boards target managed fleets. The Socket vs chipset: what decides whether a CPU works guide explains how chipset and BIOS revisions decide whether a given board starts with a given processor.
Memory, PCIe and cooling
Memory choice follows the board: DDR5 up to 5600 MT/s or DDR4 up to 3200 MT/s over two channels to 192 GB. A DDR4 industrial board reuses existing modules, while a DDR5 board gives more bandwidth to packet buffers and to the integrated graphics. ECC is supported, which matters for systems that run for months without local staff.
The processor supplies 20 lanes, sixteen at PCIe 5.0 for a network adapter or accelerator plus four at PCIe 4.0 for NVMe storage, with eight DMI 4 lanes to the platform controller. Intel UHD Graphics 770 with 32 execution units drives up to four displays, including 8K over DisplayPort, so control room monitors and signage panels connect without a separate card.
At 45 W base power the thermal load suits compact industrial heatsinks, sized from the board thermal guide rather than a desktop tower rating. Tray processors ship without a cooler, and mounting uses the 78 mm LGA 1700 hole pattern described in the CPU cooler compatibility by socket guide. Size the heatsink for sustained all core load at the installation ambient temperature, not for brief boost excursions.
Upgrade paths
Inside one industrial board the path runs through the Bartlett Lake stack itself. A 273PTE system can step to the 65 W or 125 W twelve core when more sustained frequency is needed, subject to the voltage regulator, the heatsink and the board support list. Moving down to a ten or eight core sibling cuts cost and heat when twelve cores sit idle.
There is no path between these parts and consumer desktop chips, even though both use the same socket. A part such as the Intel Core i5-14400 belongs to the Raptor Lake Refresh desktop range with its own board firmware, and neither family boots on the other family boards. Treat the embedded and desktop lines as separate platforms that happen to share a package.
When the workload outgrows LGA 1700 industrial boards entirely, the replacement is a newer embedded platform with its own board and memory, checked with the How to find your CPU socket type guide. Long availability windows on industrial boards mean the 273PTE can also stay where it is until the system retires.
Frequently asked questions
What socket does the Intel Core 9 273PTE use?
It uses LGA 1700, marked FCLGA1700 in Intel documents. Only industrial boards with firmware support start with it.
Can I install the 273PTE in my Z790 gaming 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.
What does the PTE suffix mean?
PTE marks the 45 W embedded power class. PE parts run at 65 W and PQE parts at 125 W, with clocks set to match each envelope.
Does the 273PTE come with a cooler?
No. It ships in trays for system builders without a boxed cooler. Cooling comes from the industrial chassis and heatsink specified for the configured power.
