Intel Core Ultra 7 155H CPU Fails Miserably Against The AMD Ryzen 7 7840U In Linux Benchmarks

Phoronix has published their review of the Intel Core Ultra 7 155H "Meteor Lake" CPU against the AMD Ryzen 7 7840U in Linux which gets utterly demolished across 370 tests in both performance and efficiency.

Known for its in-depth look at the Linux ecosystem, Phoronix took it upon itself to measure the performance of the Intel Core Ultra "Meteor Lake" CPUs in Linux since neither Intel nor any 3rd party vendor shared those results. Michael Larabel went out and purchased the new ACER Swift laptop featuring an Intel Core Ultra 7 155H CPU. This chip has 16 cores, 22 threads, 24 MB of L3 cache, and a TDP that ranges from 28W and up to 115W (MTP).

For comparison, an AMD Ryzen 7 7840U laptop (Framework 13) was used. The 7840U is an 8-core and 16-thread chip with 16 MB of L3 cache, up to 5.1 GHz clocks, and a TDP that ranges from 28W and scales up to 30W. Both laptops feature 16 GB of memory and were tested in Ubuntu 23.10 (in Linux 6.7-rc5) using the latest firmware for both AMD and Intel chips.

The tech outlet ran an impressive 370 benchmarks ranging from browser tests, HPC, content creation, video encoding, code compilation, audio encoding, AI benchmarks, PyTorch, GIMP, Python, PHP Scripting, and more. At the end of the tests, it was concluded that the Intel Meteor Lake "Core Ultra 7 155H" CPU was severely behind the several months-old AMD Ryzen 7 7840U.

For comparison, the AMD Ryzen 7 7840U CPU outperformed the Intel Core Ultra 7 155H in 80% of the 370 tests with the blue team only managing a 20% lead in these benchmarks. In overall CPU-to-CPU performance, the AMD Ryzen 7 7840U offered an average of 28% faster performance at similar or lower power which is simply insane considering Meteor Lake was expected to be Intel's return to form with class-leading efficiency.

Furthermore, the comparison was between Meteor Lake-H and an AMD Ryzen 7000U chip, this wasn't even a 7000(HS) SKU which would've offered even better performance and likely retained a similar efficiency lead. Phoronix also plans on sharing more testing such as iGPU (Arc Xe vs RDNA 3) and NPU AI performance in upcoming reviews of Core Ultra CPUs.

Michael sums up the situation perfectly in his conclusion:

When taking the geometric mean of all 370 benchmark results, the Ryzen 7 7840U enjoyed a 28% lead over the Intel Core Ultra 7 155H in these Linux CPU performance benchmarks. This was all the while the Ryzen 7 7840U was delivering similar or lower
