Verdict

The Intel Core Ultra 7 155H is a high-end Meteor Lake laptop processor featuring a unique 16-core, 22-thread configuration consisting of 6 Performance cores, 8 Efficient cores, and 2 Low Power Island cores with a maximum turbo frequency of 4.8 GHz. Built on the Intel 4 (7nm) process, it integrates an 8-core Intel Arc GPU running up to 2.25 GHz and a dedicated AI Boost NPU for hardware-accelerated AI tasks. Key advantages include significant improvements in integrated graphics performance that rival some entry-level discrete GPUs, enhanced power efficiency for better battery life in thin-and-light laptops, and support for modern standards like PCIe 5.0 and Wi-Fi 7. However, main drawbacks include negligible single-core performance gains over previous generations, inconsistent clock speeds due to thermal throttling in certain laptop chassis, and a complex naming convention that can be confusing for consumers.
