Intel Core Ultra 7 155H Meteor Lake vs. AMD Ryzen 7 7840U On Linux In 300+ CPU Benchmarks

There were cases of the Intel Core Ultra 7 155H outperforming the AMD Ryzen 7 7840U on Ubuntu Linux with all these CPU/processor focused tests, but more often than not it was the existing AMD Zen 4 processor leading....

In fact, out of 370 benchmarks run on both the Ryzen 7 7840U and Core Ultra 7 155H focused strictly on the processor performance, the Ryzen 7 7840U was the best performer 80% of the time!

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 power consumption than the Core Ultra 7 155H with these tests on Ubuntu 23.10 with the Linux 6.7 kernel at each system's defaults. The Core Ultra 7 155H also had a tendency to have significantly higher power spikes than the Ryzen 7 7840U.

At least from where things stand on the CPU side, the AMD Ryzen 7 7840U currently stands stronger than the Core Ultra 7 155H for a majority of Linux CPU use-cases. It will be interesting to see next up how the integrated Arc Graphics perform against the AMD Radeon RDNA3 graphics -- stay tuned for that article that should be completed by tomorrow. And then after that is looking at the Meteor Lake NPU performance -- at least there Intel is the winner with AMD not yet supporting Ryzen AI on Linux...

A larger Linux laptop performance comparison will also come in the next week or two. It will also be interesting to see if Intel has more Meteor Lake CPU optimizations on the way such as for better optimizing P vs. E core handling or any other tuning to help allow these new laptop processors better compete against the existing AMD Zen 4 laptop processors. I will also have up some Windows 11 vs. Linux benchmarks in the coming days on the Acer Swift Go 14 that should shed some light on how much Linux is to blame for this rather poor showing on the CPU side out of the Core Ultra 7 155H.

Those wanting to see all of my 370 benchmarks in full along with all of the per-test CPU power consumption numbers for this head-to-head comparison can do so via this OpenBenchmarking.org result page. Back to benchmarking the Meteor Lake graphics and the other ongoing tests.

Update: Intel Meteor Lake Arc Graphics benchmarks on Linux have now been published. Much better performance and power efficiency than the CPU side!
