With 16 cores, Arrow Lake H offers the same number of cores as its direct predecessor Intel Meteor Lake H, also known as Core Ultra 100H. However, unlike the 2024 generation chip, the Arrow Lake cores are based on the Lunar Lake core design – the Lion Cove P cores and Skymont E cores will now power the H series as well. The processors themselves are not made in Intel’s foundry, unlike the older Meteor Lake. Instead, they are manufactured by TSMC in their efficient N3 node.
The significantly higher efficiency than Meteor Lake’s Redwood Core P and Crestmont E cores, which were made on Intel 4, should make laptops equipped with Arrow Lake H more energy efficient and more durable. And according to Intel, even performance should improve, despite the fact that Lion Cove removes hyperthreading. Intel announces a 15% performance increase compared to Meteor Lake H, despite a lower total number of threads (Ultra 9 185H: 22 threads, Ultra 9 285H: 16 threads).
On the GPU side, Arrow Lake is less revolutionary, retaining the Xe cores already used in Meteor Lake. However, the GPU now contains new XMXs, which Intel says will improve AI performance for the GPU and may also be beneficial for gaming. As with the GPU, Intel uses the Meteor Lake NPU, so the NPU performance stagnates at 11 TOPS. However, Intel claims that the H-series chips should still perform well in AI, since the platform’s total TOPS (i.e., combined CPU, GPU, and NPU performance) reaches 99 TOPS.
-When it comes to TDP, H-class chips continue to be optimized to run at 28W, with the Ultra 9 being the exception, since it’s rated to run at 45W. Maximum power consumption of CPUs is 115W, but that’s something OEMs can configure – it can also be set to 60W instead. This once again shows the flexibility that the H series offers compared to other Intel CPU series.
New to this generation of Intel H-class CPUs is support for Thunderbolt 5. The Arrow Lake H-series also supports a single PCIe Gen 5 lane for the first time, enabling PCIe Gen 5 storage.
