Recently, the Tiger Lake H45 processor Intel Core i7-11800H appeared on CPU-Z Validator offering up good results that held up well against the rival AMD Ryzen 7 5800H. A little further down the Team Blue product stack is the Intel Core i5-11400H, which was also spotted by data-miner APISAK after a CPU-Z run as part of an MSI system that also featured an Nvidia GeForce RTX 3050 Laptop GPU. The recorded single-thread score was a healthy 528 points while the multithread score was a bit limper on 3,301 points.
Moving to a comparison, it seems fair to choose the AMD Ryzen 5 5600H here, as it is also a 6-core, 12-thread part with a default 45 W TDP. The Intel Core i5-11400H has the boost-rate advantage, at 4.5 GHz to 4.2 GHz, but the Cezanne Zen 3 chip has the power efficiency superiority thanks to 7 nm manufacturing compared to 10 nm for the Tiger Lake chip. The Ryzen 5 5600H has reported scores of 547 points (single) and 4,228 points (multi) in this particular benchmark, leaving it +3.69% and an intimidating +28.08% ahead of the i5-11400H, respectively.
It could be hoped for that the Intel Core i5-11400H would perform better here, especially in the single-thread discipline. However, it appears the Tiger Lake chip only reached a maximum rate of 4.076 GHz in testing and was at stepping level 1 (architecture: revision 0). This means there could be more performance reserves to tap into with this particular processor in future testing, where hopefully it will give the Cezanne Zen 3 chip a closer run for the money, especially in the multithread benchmark.
