What the Processor U300 is
The Processor U300 is the 5-core entry of Raptor Lake-U for thin laptops from January 3, 2023. One Raptor Cove Performance-core with hyperthreading plus 4 Gracemont Efficient-cores give 5 cores and 6 threads, with the P-core at 1.2 GHz base and up to 4.4 GHz turbo. The package carries 8 MB of Smart Cache. Base power is 15 W with 55 W turbo for thin bodies that prize battery over threads.
UHD Graphics with 48 execution units to 1.1 GHz cover everyday display and streaming. Broad memory support from DDR4-3200 to LPDDR5x-5200 lets makers tune price against bandwidth. The single P-core burst covers interactive threads while E-cores handle background services.
Entry thin buyers land here for the lowest Raptor Lake-U price with responsive bursts. Five cores suit browsing, docs and calls at 15 W, while i3 U parts add a second P-core for heavier multitasking. Boards that support Raptor Lake-U cover the family with the same firmware. The How to find your CPU socket type guide helps confirm BGA 1744 fit.
Socket and motherboard compatibility
The U300 solders to BGA 1744 on thin laptop boards with no socketed path. Board makers set memory type and power limits. BGA 1744 does not cross to LGA 1700 desktop boards. Maker pages list the BGA package as the fit reference.
Platform IO comes from the SoC plus board wiring, with NVMe, wireless and display outputs from the design. Factory firmware carries Raptor Lake-U support.
Memory, PCIe and cooling
DDR4-3200, LPDDR4x-4267, DDR5-5200, LPDDR5-5200 or LPDDR5x-5200 in two channels feeds CPU and UHD graphics together. Soldered LPDDR5 suits thin bodies, while SODIMM suits serviceable fleets. Dual channel doubles graphics bandwidth.
PCIe Gen4 lanes wire NVMe plus wireless controllers. Cooling is a single pipe and blower for 15 W with short 55 W bursts.
Upgrade paths
No CPU change is possible on soldered BGA 1744. SODIMM and NVMe swaps move where slots exist, while soldered memory stays fixed.
Within Raptor Lake-U on BGA 1744 the steps up are i3 U parts with an extra P-core. Outside thin power, P parts on BGA 1744 add threads with stronger cooling.
