AMD's Ryzen mobile chips beat Intel's new Meteor Lake in Linux benchmarks — Ryzen 7 7840U and Intel Core Ultra 7 155H go head-to-head

Phoronix ran a series of over 300 CPU benchmarks on both mobile CPUs, with favorable results for AMD.

Within a week of Intel Meteor Lake's Dec. 14 release date, the Core Ultra 7 155H has been given a run of over 300 CPU benchmarks under Linux in a head-to-head with a Ryzen 7 7840U. This detailed testing was originally posted on Phoronix.com. The testing setup involved two laptops, with the 7840U powered by a Framework laptop while the 155H ran from an Acer Swift Go 14.

There are some core takeaways to glean from the hundreds of CPU benchmarks run. In its writeup, Phoronix provided a geometric mean of all test results done across both CPUs, which showed the AMD Ryzen 7840U enjoying a clean 28% lead in performance. 

It's important to note that these are purely CPU-bound benchmarks, so the powerful iGPUs present in both CPUs aren't actually being pitted against each other in these tests.

The geometric mean of all of Phoronix's CPU benchmarking reveals a solid AMD lead, at least in Linux.

This doesn't necessarily mean that Ryzen 7 7840U enjoys an overall 28% performance lead in Linux. In fact, in the testing of both CPUs, the Intel Core Ultra 7 155H scored higher on 75 of 370 benchmarks. This means that while the 7840U is clearly the stronger overall performer for a Linux laptop, the Core Ultra 7 155H still managed to eke out a lead in specific workloads.

These results shouldn't necessarily be taken as a permanent indictment on Meteor Lake's Linux performance. With time, Intel may be able to improve Linux's Meteor Lake support in order to provide performance standings more in line with how the chips perform on Windows. 

On the Windows side, the Core Ultra 7 155H is supposedly significantly faster than the 7840U — but that's according to Intel's testing, which we haven't been able to verify with our benchmarking at Tom's Hardware just yet.

In any case, it seems like the clear winner for today between the Ryzen 7 7840U and Core 7 Ultra 155H is the 7480U — at least if you're using Linux.

    I'm sure that'll be completely accurate. After all, none of these companies - Intel, AMD, Nvidia, Apple etc - are known for skewing benchmark figures in order to show any kind of advantage for their hardware.

    Without details on why these two particular processors were chosen, this is mostly an anecdote. As a former electronics test engineer, much more rigor is needed before making broad statements like AMD beats Intel in Linux benchmarks. The original author, Michael Larabel, mentions several caveats that are not included in this brief post. Makes me wonder if Christopher Harper is an AMD fanboy.

    They were chosen because they are direct competitors with directly competing AI engines in the laptop CPU market. Simple as that afaict.

    I'm looking forward to see how the new AMD 88XX series perform. From what I've been reading/hearing, they are going to be a big jump up in performance.
