The test system for today’s review is the XMG Core 17, the same sort of laptop we’ve been using for our latest look into the GeForce RTX 3050 and RTX 3050 Ti. This means the 11400H requires a discrete GPU to get adequate graphics performance. You’ll see here that it’s listed as having UHD Graphics with the same clock speeds as other processors, but what Intel isn't telling you is that the Core i5 model has just 16 execution units in its Xe GPU, compared to 32 on higher tier models. What Intel has left out of this chart are exact GPU specifications. The 11400H tops out at 4.5 GHz single core and 4.1 GHz all-core. The base clock at 45W is higher as it doesn’t need to be split across as many cores, sitting at 2.7 GHz, however boost clocks are also reduced relative to higher end models. Unlike the Core i7 and Core i9 models which pack 8 cores, the Core i5-11400H uses a cut down version with 6 cores and 12 threads, along with 12 MB of 元 cache. It also comes with an integrated Xe GPU, though the GPU has been cut down significantly compared to top end Tiger Lake models.
The i5-11400H is a Tiger Lake H45 processor, so it comes with all the architectural upgrades we’ve talked about before: 10nm SuperFin process, Tiger Lake architecture with improvements to cache sizes, clock speeds, and efficiency, plus new features like support for PCIe 4.0.
If you don’t want to grab a Core i7-11800H, which we’ve already reviewed, then what is the Core i5-11400H bringing to the H-series CPU segment? The Core i5-11400H mobile CPU comes as a direct competitor to AMD's Ryzen 5 5600H, which means it's used across many mainstream, affordable laptops usually offered as the entry-level option in many popular laptop series.
