AMD Ryzen 7 7840U Outperforms Intel Core Ultra 7 155H in Linux: Phoronix’s Comprehensive Analysis

In a recent performance showdown, Phoronix, known for its in-depth analysis of the Linux ecosystem, conducted comprehensive tests pitting the Intel Core Ultra 7 155H “Meteor Lake” CPU against AMD’s Ryzen 7 7840U. The results were nothing short of a resounding victory for AMD, as the Intel processor faced a significant defeat across 370 tests in both performance and efficiency in a Linux environment.

Phoronix, in its pursuit of unbiased insights, took the initiative to independently evaluate the performance of Intel’s Core Ultra “Meteor Lake” CPUs in Linux. With no official results shared by Intel or any third-party vendors, Michael Larabel, from Phoronix, acquired an ACER Swift laptop featuring the Intel Core Ultra 7 155H CPU for a thorough examination. This chip boasts an impressive 16 cores, 22 threads, 24 MB of L3 cache, and a Thermal Design Power (TDP) ranging from 28W to a whopping 115W (MTP).

For a fair comparison, Phoronix utilized a laptop equipped with the AMD Ryzen 7 7840U (Framework 13). This AMD processor is an 8-core, 16-thread chip featuring 16 MB of L3 cache, clocking up to 5.1 GHz, with a TDP ranging from 28W to 30W. Both laptops, equipped with 16 GB of memory, underwent testing on Ubuntu 23.10, utilizing Linux 6.7-rc5, and the latest firmware for both AMD and Intel chips.

The benchmarking process was extensive, covering a wide array of tests including browser performance, high-performance computing (HPC), content creation, video encoding, code compilation, audio encoding, AI benchmarks, PyTorch, GIMP, Python, PHP scripting, and more. The conclusive findings painted a stark picture: the Intel Meteor Lake “Core Ultra 7 155H” CPU fell significantly behind the AMD Ryzen 7 7840U.

Breaking down the numbers, the AMD Ryzen 7 7840U outperformed the Intel Core Ultra 7 155H in a staggering 80% of the 370 tests. Intel’s processor managed only a meager 20% lead in these benchmarks. In terms of overall CPU-to-CPU performance, the AMD Ryzen 7 7840U showcased an average of 28% faster performance at similar or lower power consumption. This outcome was particularly surprising, given the anticipation surrounding Meteor Lake as Intel’s return to form with class-leading efficiency.

What’s more, the comparison was made between Meteor Lake-H and an AMD Ryzen 7000U chip, not even the 7000(HS) SKU, which could have offered even better performance and likely maintained a similar efficiency lead. Phoronix hinted at future reviews, promising additional insights into iGPU (Arc Xe vs RDNA 3) and NPU AI performance for Core Ultra CPUs.

In his concluding remarks, Michael Larabel summed up the situation succinctly. The geometric mean of all 370 benchmark results showed that the Ryzen 7 7840U enjoyed a commanding 28% lead over the Intel Core Ultra 7 155H in Linux CPU performance. Remarkably, the Ryzen processor achieved this lead while delivering similar or lower power consumption compared to the Core Ultra 7 155H. Notably, the Intel processor tended significantly higher power spikes than its AMD counterpart.

The overall narrative painted a picture of Intel shockingly falling behind AMD in the Linux ecosystem. Despite being a relatively new architecture, Intel’s Meteor Lake chip, with its pre-launch patches and early support, failed to surpass the efficiency demonstrated by AMD’s Ryzen 7 7840U. While the article acknowledged the potential for Intel’s lineup to improve over time, especially with ongoing advancements and optimizations, it underscored the present dominance of AMD in the Linux landscape.
