Intel Core Ultra 7 155H Tested in Linux; Slower than AMD?
Intel’s Meteor Lake architecture is brand new and built on the Intel 4 manufacturing process. The new Core Ultra processors use this architecture, and recently, theCore Ultra 7 155Hhas been taken through its paces in Linux-based benchmarks.Phoronix.comhas taken the tests, which ultimately reveal that AMD’s Ryzen 7 7840Uwinsover the Core Ultra 7 155H.
A total of370 testswere performed on these two processors from AMD and Intel. These were CPU-centric benchmarks and tests taken on the Linux OS. Out of these,Core Ultra 7 155Hhad a lead in only75tests, while theRyzen 7 7840Uwon in295others. According to the conclusive ‘geometric mean’ of all results, theAMD Ryzen 7 7840U had a 28% lead over the Intel Core Ultra 7 155H.
So, what exactly is going on?Is the Intel Core Ultra worse than the AMD Ryzen 7 7840U?The answer is not an easy one. Firstly, every processor can have its own strengths. A high-performance one (such as H-Series chips from Intel) prioritizes performance over efficiency. Other chips (such as the P/U series) are focused on efficiency rather than being performant.
It is possible these tests do reflect the accurate performance of Core Ultra & AMD Ryzen (in Linux-centric CPU benchmarks). But, this testingdoes not represent the full story.
The latestIntel Core Ultraprocessor is made up of the Meteor Lake integratedArc GPU, compute tile P-cores & E-cores, a new type of Low Power (LP) E-Core, and also the brand new neural processing unit (NPU) component whichaccelerates AI. Together, Intel is touting this new generation having ‘three AI engines‘. In applications that can take advantage of this hybrid architecture, Core Ultra processors work better.
Intel’s Benchmarks Say The Opposite
Intel had released its ownbenchmarkscomparing Core Ultra processors against AMD Ryzen at the launch event. Here, we can see that in the ‘AI Application performance’ benchmarks, the Intel chip is doing better. In anothercontent creation test, we can see theCore Ultra outperform the AMD Ryzen.
That is the complete opposite of what we saw previously in Phoronix’s testing, which was performed on Linux-centric CPU benchmarks. Do note thatAMD Ryzen 7000 processors for laptopswere released back in May 2023, and Intel’s Core Ultra came out in December 2023.
These are benchmarks given by Intel. Making a final judgment call on who is better will require intensive testing & comparisons. Both companies have launched their new lineup of processors with updated architecture & evolved manufacturing processes.
For now, not a lot of consumers are able to get their hands on the latest Core Ultra laptops. It will take some time for the new laptops to release properly into the market (mid 2024).It is not fair to judge the Core Ultra chips this early, especially when the Core Ultra 9 185H (highest-end Meteor Lake CPU) is not coming out until later.
When possible, it will be interesting to compare the best laptop CPUs available today against each other.
