Verdict

The Intel Core Ultra 5 135H is a mid-range Meteor Lake-H laptop processor featuring 14 cores (4 Performance, 8 Efficient, and 2 Low Power Efficient) and 18 threads, with a max turbo frequency of 4.6 GHz and 18 MB of L3 cache. Its standout characteristics include an integrated Intel Arc GPU (8-cores) and a dedicated AI Boost NPU for hardware-accelerated AI tasks, all operating within a base TDP of 28W (scalable up to 115W). Main pros include significantly improved integrated graphics performance for casual gaming and video editing, excellent power efficiency for longer battery life, and modern connectivity support like PCIe 5.0 and Wi-Fi 7. However, potential cons include a reduced L3 cache compared to higher-tier Ultra 7 models and a dependency on high-speed multi-channel RAM to reach peak GPU performance.
