What the Core Ultra 7 155H is
The Core Ultra 7 155H is the 16-core mainstream of Meteor Lake H for performance thin laptops from December 14, 2023. Six Redwood Cove Performance-cores with hyperthreading plus 8 Crestmont Efficient-cores and 2 low-power island E-cores give 16 cores and 22 threads, with P-cores at 1.4 GHz base and up to 4.8 GHz turbo. The package carries 24 MB of Smart Cache and an AI Boost NPU. Base power is 28 W with turbo up to 115 W where the OEM cooling allows.
Intel Arc Graphics with 8 Xe-cores to 2.25 GHz handle creation and light play without a discrete card. Memory reaches DDR5-5600 or LPDDR5x-7467 for bandwidth that feeds the full GPU well. PCIe Gen5 lanes from the CPU wire fast NVMe plus Thunderbolt 4 docks. The NPU offloads camera effects and local inference from CPU cores.
Mainstream performance buyers land here for full H graphics and threads below Ultra 9 pricing. Six P-cores keep builds and timelines moving while E-cores cover background work. Owners who need peak turbo step to 165H on the same BGA 2049 base. The How to find your CPU socket type guide helps confirm BGA 2049 fit.
Socket and motherboard compatibility
The 155H solders to BGA 2049 on performance thin boards with no socketed path. Board makers set memory type, power limits and Thunderbolt provisioning, so sustained behaviour varies by chassis. BGA 2049 does not cross to LGA 1851 desktop boards. Maker pages list the BGA package as the fit reference.
Platform IO comes from SoC tiles plus board wiring, with NVMe Gen5, wireless and display outputs from the design. Factory firmware carries Meteor Lake support, so buyers weigh memory form and cooling class.
Memory, PCIe and cooling
DDR5-5600 SODIMM or LPDDR5x-7467 soldered memory feeds CPU, Arc graphics and NPU together. Capacity reaches 64 GB on LPDDR5 or 96 GB on DDR5 designs. Dual channel doubles graphics bandwidth against single channel.
PCIe Gen5 with 8 CPU lanes plus Gen4 lanes wire NVMe and Thunderbolt controllers. Cooling uses dual pipes or vapour with fans for 28 W sustained and up to 115 W bursts. The 115 W mode needs capable VRMs and cooling chosen by the OEM.
Upgrade paths
No CPU change is possible on soldered BGA 2049. SODIMM and NVMe swaps move where slots exist, while soldered LPDDR5X stays fixed. Thunderbolt docks add displays and networking.
Within Meteor Lake on BGA 2049 the steps up are 165H and 185H with higher turbo on the same 16-core layout. Outside mobile, Arrow Lake-H on BGA 2049 adds newer cores where boards support it.
