Verdict

The Intel Core Ultra 5 134U is a lower mid-range Meteor Lake-U processor designed for ultra-thin laptops, featuring a 12-core, 14-thread architecture (2 Performance, 8 Efficient, and 2 Low-Power Efficient cores) with a max turbo frequency of 4.4 GHz and 12 MB of L3 cache. Its main advantages include extreme energy efficiency with a base power of just 9W (max 30W), an integrated 4-core Intel Graphics unit running up to 1.75 GHz, and a dedicated NPU for AI acceleration (11 TOPS). However, its primary drawbacks are the significant reduction in L3 cache compared to higher-tier models and lower overall multi-threaded performance, which often trails slightly behind predecessors like the i5-1335U.
