Intel Processor U301L socket: LGA 1700
The Intel Processor U301L uses LGA 1700, the LGA socket for Raptor Lake-PS edge processors with DDR5 or DDR4 and PCIe expansion. The 5-core chip at 15 W fits edge boards with vendor BIOS support.

What the Processor U301L is
The Processor U301L is a 5-core and 6-thread edge processor that Intel launched in the second quarter of 2024 for entry LGA edge nodes. One Performance-core with 2 threads plus 4 Efficient-cores give 6 threads at 1.2 GHz base and up to 2.2 GHz boost. Cache is 8 MB of Smart Cache. The 15 W base suits fanless gateways where steady low power matters more than burst speed.
Intel Graphics cover display output for kiosks and thin clients from shared memory. The PS package brings Raptor Lake efficiency to industrial boards with longevity support. DDR5 or DDR4 SODIMM options let fleets reuse memory during refresh cycles.
Entry gateways with fixed workloads fit here. Five cores handle terminal services, signage playback and sensor aggregation at low clocks. Buyers who need faster bursts for interactive kiosks should take the Intel Processor U300L with 4.4 GHz turbo instead, since this U301L caps peaks for thermal headroom.
Socket and motherboard compatibility
The U301L fits LGA 1700 PS edge boards with 15 W delivery. Desktop Alder Lake and Raptor Lake chipset support does not imply PS support, so industrial lists govern. The neutral sentence appears where claims are board-specific.
Low-power PS boards pair this SKU with DDR5 or DDR4 SODIMM, M.2 and multi-LAN. Wide temperature operation and legacy I/O suit factory floors. BIOS from the PS branch with the U301L ID is required.
Within the U300L class the U301L is the low-turbo option with 8 MB cache. The Intel Processor U302L above adds 2 MB cache for larger sets. The How to find your CPU socket type guide helps confirm PS versus desktop LGA 1700 boards.
Memory, PCIe and cooling
DDR5-5200 or DDR4-3200 in two channels via SODIMM is the board choice. DDR4 reuse saves money for large fleets, while DDR5 lifts bandwidth for graphics. Shared graphics reservations should be subtracted from OS headroom.
PCIe up to 20 lanes with PCH serves NVMe, Ethernet and serial expansion. Most thin boards expose one M.2 plus wireless, with the rest over USB and LAN. Fixed wiring means expansion plans must follow the manual.
Cooling is 15 W fanless-capable with fin stacks. No retail cooler ships with edge tray parts. Dust and inlet temperature decide whether 2.2 GHz bursts repeat, so filtered enclosures help most.
Upgrade paths
LGA allows steps within PS where listed, such as to the Intel Processor U302L for more cache. SODIMM and NVMe can also expand. BIOS must include the target microcode.
Higher turbo needs the U300L with 4.4 GHz peak on stronger cooling. A working U301L serves entry roles for years. Desktop LGA 1700 Core parts are a different board class.
Frequently asked questions
What socket does the Processor U301L use?
It uses LGA 1700 PS edge packaging for 15 W boards. Vendor lists decide fit.
How fast is the Processor U301L?
Five cores and 6 threads at 1.2 GHz base and up to 2.2 GHz boost, with 8 MB of cache at 15 W.
What memory does the U301L support?
DDR5-5200 or DDR4-3200 in two channels. Boards pick one type per design.
Does the U301L need a BIOS update?
Check the PS vendor list. Desktop 600 and 700 series coverage does not transfer automatically.
