Intel Core Ultra 5 135HL Review

Intel Core Ultra 5 135HL 14-core 18-thread embedded/aio (lga-packaged mobile silicon) processor, 1.7GHz base / 4.3GHz boost, 45W TDP, Meteor Lake, LGA 1851 (embedded/AIO variant) socket

The Intel Core Ultra 5 135HL is an LGA-packaged variant of Intel's mobile silicon built for embedded systems and all-in-one PCs that need a socketed thermal solution. Built on Intel's Meteor Lake architecture, it pairs 14 cores and 18 threads with a 1.7GHz base clock that boosts up to 4.3GHz, an on-die NPU rated at 11 TOPS (NPU 3), and Intel Graphics (Xe-LPG) graphics, all within a 45W envelope.

Performance and Architecture

With 14 cores and 18 threads, the Intel Core Ultra 5 135HL is built on Intel's Meteor Lake generation. Its 1.7GHz base clock boosts to 4.3GHz, and its Intel Graphics (Xe-LPG) integrated graphics and 11 TOPS (NPU 3) NPU support on-device AI features alongside everyday computing and light content creation.

Platform and Efficiency

The Intel Core Ultra 5 135HL uses the LGA 1851 (embedded/AIO variant) platform in a 45W envelope, positioning it as embedded systems and all-in-one PCs that need a socketed thermal solution. Its NPU brings Copilot+ style on-device AI acceleration to supported workloads.

Comparison to Alternatives

Within the Core Ultra lineup in this catalog, the Intel Core Ultra 5 135HL sits in the 5-series tier alongside other Meteor Lake parts, differentiated mainly by clock speed, core count, and TDP. Against AMD's Ryzen AI Mobile processors in this catalog, Intel's Core Ultra competes on NPU throughput, integrated graphics, and platform efficiency, while against Intel's own prior-generation Core i mobile parts in this catalog it adds the on-die NPU and improved efficiency cores.
