Benchmarks & Specs

Last updated:
The Intel Core Ultra 5 338H is based on the modern Panther Lake H architecture for mobile devices. Through production in the fine 2 nm process, this chip achieves remarkable efficiency in everyday use. We like the approach that Intel focuses on a compact design and low heat generation here.

The integrated graphics unit named Intel Arc B370 provides an absolutely solid graphical representation for everyday tasks. With a memory bandwidth of 137 GB/s, data is processed quickly enough for most applications. The processor also offers a Level 2 cache of 16 MB for smooth data management. Additionally, 18 MB of Level 3 cache is available, which noticeably supports general speed.

In daily operation, the Intel Core Ultra 5 338H shows a balanced and truly reliable performance. The architecture ensures that modern laptops can be built thinner without overheating. We noticed in our tests how stably the system works even under moderate load. It is not a high-end monster, but for the mid-range, the equipment is really well chosen.

The focus is clearly on a good ratio between energy consumption and available computing power. Users benefit from a modern platform that offers sufficient reserves for the coming years. Overall, the hardware leaves a well-thought-out impression for mobile users with high demands. The modern technology and efficiency make the Intel Core Ultra 5 338H a good choice.

  • Production in the advanced 2 nm process
  • Integrated graphics unit of the Intel Arc B370 type
  • Optimized efficiency through the modern Panther Lake H architecture
  • Balanced ratio of cache and memory bandwidth
