Core Ultra 7 255H Details

The Intel Core Ultra 7 255H stands out as a high-performance mobile processor designed for demanding workloads, particularly in thin-and-light laptops where power efficiency and integrated graphics are critical. Launched in early 2025 as part of Intel’s Arrow Lake-H lineup, this chip leverages a 3 nm process node fabricated by TSMC, marking a significant leap in transistor density and power efficiency. Despite being a mobile processor, it delivers desktop-level performance, thanks to its 16-core, 16-thread design and a turbo frequency of up to 5.1 GHz. With a 28 W TDP, the Core Ultra 7 255H strikes a balance between performance and thermal constraints, making it ideal for portable systems that require sustained compute power without excessive heat or battery drain.

Equipped with Intel’s latest Arc Graphics 140T integrated GPU, the processor supports modern graphics APIs and delivers competitive performance for light gaming and multimedia tasks. The GPU features 140 execution units and operates at frequencies suitable for 1080p gaming and content creation. The chip also includes a Neural Processing Unit (NPU) rated at up to 13 TOPS, enhancing AI workloads such as real-time image processing and machine learning inference. This makes the Core Ultra 7 255H particularly attractive for applications leveraging AI acceleration, including video editing, photography, and virtual assistants.

In terms of memory, the processor supports DDR5 and LPDDR5X at up to 6400 MT/s, enabling fast data throughput across a dual-channel interface. It also supports ECC memory, a rare feature in mobile platforms, making it suitable for professional environments where data integrity is paramount. The architecture includes 24 MB of L3 cache and a total of 2.861 MiB of L2 cache, ensuring low-latency access to frequently used data. The processor connects via PCIe Gen 5 with 20 lanes dedicated to the CPU, offering high bandwidth for fast storage and expansion cards.

Benchmarking reveals the Core Ultra 7 255H as a strong performer, scoring 7036 in Singlecore and 6513 in Multicore on the PassMark test suite. It ranks #67 in single-core and #155 in multicore performance among 2060 processors, placing it just behind higher-tier mobile and desktop chips like the Ryzen 7 7700 and Core i5-13500. Its overall score of 6827 lands it at #81 in the broader ranking, outperforming many mainstream mobile CPUs such as the Ryzen 7 7800X3D and Ryzen 7 8700G. While it trails top-tier processors like the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K, its efficiency and feature set make it a compelling choice for high-end laptops.

As of March 2026, the Core Ultra 7 255H remains a top contender in the mobile segment, especially for users seeking a blend of AI acceleration, integrated graphics, and high single- and multi-threaded performance. Its competitive positioning, combined with support for modern technologies like AVX2, FMA3, and Intel’s VT-x virtualization, makes it well-suited for content creators, engineers, and professionals who need a portable system capable of handling intensive workloads without relying on discrete graphics.
