Linux Testing Reveals Intel Core Ultra 7 155H Slower Than AMD

The latest Intel Meteor Lake architecture, developed on the Intel 4 manufacturing process, debuts with the Core Ultra processors. In recent Linux-based benchmarks conducted by, the Core Ultra 7 155H underwent rigorous testing, revealing that AMD’s Ryzen 7 7840U outperformed it.

A comprehensive set of 370 CPU-centric benchmarks on the Linux OS compared these processors. Despite the Core Ultra 7 155H leading in 75 tests, the Ryzen 7 7840U triumphed in 295. Ultimately, when considering the overall geometric mean of all results, the AMD Ryzen 7 7840U held a significant 28% performance advantage over the Intel Core Ultra 7 155H.

Determining the superiority between the Intel Core Ultra and the AMD Ryzen 7 7840U isn’t straightforward. Each processor comes with its own set of strengths. High-performance chips like Intel’s H-Series prioritize raw power, while others like the P/U series focus more on efficiency.

While these tests in Linux-centric CPU benchmarks might indicate the performance differences between the Core Ultra and AMD Ryzen, it’s crucial to note that these tests don’t paint the complete picture. There’s more nuance to their capabilities beyond these specific benchmarks.

The newest Intel Core Ultra processor combines the Meteor Lake integrated Arc GPU, compute tile P-cores & E-cores, a novel Low Power (LP) E-Core, and introduces a cutting-edge neural processing unit (NPU) designed for AI acceleration. Intel boasts about this generation’s “three AI engines.” In tasks leveraging this hybrid architecture, Core Ultra processors demonstrate improved performance.

Intel’s Benchmarks Contradict This

At Intel’s launch event, they unveiled benchmarks comparing the Core Ultra processors with AMD Ryzen. In these tests, the Intel chip demonstrated superior performance in AI application tasks and content creation compared to AMD Ryzen.

This stands in stark contrast to Phoronix’s earlier testing, which focused on Linux-centric CPU benchmarks and showcased a different performance narrative. Worth noting, AMD Ryzen 7000 laptop processors hit the market in May 2023, while Intel’s Core Ultra was released in December 2023.

Intel’s provided benchmarks offer a glimpse, but a comprehensive judgment demands extensive testing and comparisons. Both Intel and AMD have introduced updated architectures and refined manufacturing processes in their new processor lineups.

Currently, the accessibility of the latest Core Ultra laptops remains limited for consumers. The widespread availability of these new laptops in the market isn’t expected until mid-2024. It’s premature to draw final conclusions about the Core Ultra chips, especially considering that the highest-end Meteor Lake CPU, the Core Ultra 9 185H, is set to arrive later. Patience is key in evaluating their true capabilities.

Comparing the top-tier laptop CPUs available currently would indeed be fascinating. What’s your take on assessing the performance of Intel Meteor Lake Core Ultra using Linux?
