Linux test results for Intel Core Ultra 7 155H reveal: slower than AMD?

The Intel 4 manufacturing process serves as the foundation for the brand-new Meteor Lake architecture from Intel. This architecture is used in the latest Core Ultra CPUs; most recently, the Core Ultra 7 155H has been tested using Linux-based benchmarks. After doing the tests, Phoronix.com has concluded that AMD's Ryzen 7 7840U wins against the Core Ultra 7 155H.

Two AMD and Intel CPUs were used for a total of 370 tests . These Linux OS benchmarks and tests were CPU-focused. Only 75 tests showed the advantage for the Core Ultra 7 155H, while Ryzen 7 7840U prevailed in 295 tests. The final "geometric mean" of all findings showed that the AMD Ryzen 7 7840U outperformed the Intel Core Ultra 7 155H by 28%.

What precisely is happening, then? Is the AMD Ryzen 7 7840U better than the Intel Core Ultra? It's not a simple question to answer. First of all, each CPU may have unique advantages. High-performance CPUs, like Intel's H-Series chips, put performance over efficiency. Other chips, like those in the P/U series, prioritise efficiency above performance.

These tests could accurately represent the performance of AMD Ryzen and Core Ultra (in Linux-specific CPU benchmarks). Nevertheless, this testing doesn't tell the whole tale.

Including the Meteor Lake integrated Arc GPU, compute tile P-cores & E-cores, a new form of Low Power (LP) E-Core, and the brand-new neural processing unit (NPU) component that accelerates AI, the most recent Intel Core Ultra processor is comprised of these components. Intel is promoting this next generation as having "three AI engines" together. Core Ultra processors perform better in programs that may benefit from this hybrid design.

The Contrary Is Said by Intel's Benchmarks

At the launch event, Intel had issued its own benchmarks pitting AMD Ryzen against Core Ultra CPUs. Here, we can see that the Intel CPU is doing higher in the "AI Application performance" benchmarks. We can observe that the Core Ultra outperforms the AMD Ryzen in another content creation test.That is the exact reverse of what we saw in earlier testing conducted by Phoronix using CPU benchmarks that were exclusive to Linux. Please take notice that Intel's Core Ultra was introduced in December 2023, while AMD Ryzen 7000 CPUs for laptops were announced back in May 2023.

These are Intel's benchmarks. Thorough testing and comparisons will be necessary before a definitive decision is made on who is superior. Both businesses have introduced their newest range of processors, which have improved production techniques and redesigned architecture.The newest Core Ultra laptops are now beyond of reach for many customers. Mid-2024 is when the new laptops are expected to be officially released onto the market. Evaluating the Core Ultra processors at this early stage is unfair, particularly because the Core Ultra 9 185H, the most advanced Meteor Lake CPU, won't be available for another several months.It will be fascinating to compare the top laptop CPUs on the market right now, if that is feasible.What do you think about Linux-based performance tests for Intel Meteor Lake Core Ultra?
