Company processors Intel they have been known for some time as those that do not have a very good ratio of performance to consumption. Unfortunately, this seems to be the case for recently introduced chips as well Meteor Lake with tiled architecture. Those paper specs don’t look too good anymore. The 28W PBP of the Core Ultra 7 155H with 16 cores and 22 threads looks nice, but the maximum MTP consumption is 64 to 115 W depending on the configuration, and that is really enough for a mobile processor. On the Phoronix server, they rushed into testing a new laptop equipped with the aforementioned processor, which was compared with another laptop equipped with an AMD Ryzen 7 7840U processor with 8 cores and 16 threads. Intel should have the upper hand on paper. In this case it was a 115H set to a lower 64W MTP.
We won’t go into details here, as the author tested the laptop in 370 different test configurations, so for more detailed information, see his pages. But the overall result is that out of these 370 tests, AMD won in 295 cases, i.e. 79.7%. Intel claimed victory in only about a fifth of the cases. In terms of average performance, the AMD Ryzen 7 7840U was 28% better. However, the fact is that it was necessary to use the Linux 6.7-rc5 kernel instead of the latest stable version of Linux 6.6, because the build on Intel was not stable with it. So it’s possible that when Linux 6.7 is final, the results of the Meteor Lake series will be better.
In a more detailed list of benchmarks, you can also look at the progress of consumption. But there is no summary result for consumption, which is a bit of a shame. Usually, Ryzen was more economical and, above all, it did not have such high peaks as Intel. But we can squeeze out at least a little bit from multi-threaded tests like FFmpeg, x265, compression via 7-Zip, Blender and the like. Both processors used to have an average consumption similar to somewhere around 30W, Intel mostly the same or a few more watts. It was worse with the maximum, where AMD reached a maximum of 51 W (ie approx. +80% above TDP), while Intel was often at its limit of 64 W (approx. +130% above TDP). It would be interesting to see how the performance would differ with the variant with MTP enabled up to 115 W.
