In early January, Intel officially announced its Tiger Lake-H mobile platform. For those who missed it, the Tiger Lake-H is the foundation of the 11th generation H-Series mobile processors. Like the 11th-generation mainstream mobile processors, the Tiger Lake-H is based on the 10nm Tiger Lake architecture, but Intel has upgraded the H-series antenna in terms of performance and features, and has also pushed the format envelope. In addition to the traditional forms of gaming laptops, Intel boasted that the new Tiger Lake-H processors from the 11th generation Core H series will appear in high-performance gaming laptops as thin as 16.4 mm, with the latest discrete graphics solutions GeForce RTX 30. from NVIDIA.
The early announcement of the Tiger Lake-H consisted of an H35 processor, led by the Intel Core i7-11375H Special Edition. The Core i7-11375H SE is a quad-core 35W (8-thread) processor, with turbo clocks up to 5 GHz and support for PCI Express 4.0. This chip is specifically designed for ultra portable laptops. Today, however, Intel is refreshing the line with Tiger Lake-H45 processors of higher power and performance, with up to 8 physical cores (16 threads).
Unlike its tenth-generation H-Series processors, which are widely used in many of today’s high-end gaming laptops, the Tiger Lake-H offers significant single-threaded performance improvements and approximately 19% improvements in multiple workloads, despite a similar number of cores. Tiger Lake-H processors also support DDR4 speeds up to 3200MHz and have better performance from Xe-graphics machines, but most laptops with the Tiger Lake-H45 will be paired with discrete graphics solutions.
Tiger Lake-H: The latest core and platform technologies
The platform also features all the latest IO and connectivity technologies, such as Killer Wi-Fi 6 / 6E, Thunderbolt 4 and Resizable BAR support, thanks to Intel’s collaboration with NVIDIA. In addition to the platform benefits listed above, Tiger Lake-H processors also have 20 reconfigurable PCI Express 4.0 tapes connected directly to the processor. These tapes can be configured in several ways, e.g. X16 / x4 or x8 / x4 / x4 / x4. The latter configuration is interesting because it offers plenty of bandwidth for a discrete GPU, while also enabling PCIe 4.0 NVMe RAID, which is the first on any mobile platform. Up to 24 additional Gen 3 PCI Express tapes will also be available via PCH.
A number of consumer and commercial Intel Core X Series 11 processors based on Tiger Lake-Hu are planned. The top consumer SKU is the Core i9-11980HK. The Core i9-11980HK is an 8-core / 16-thread processor, with a base clock of 2.6 GHz and a maximum turbo clock of 5 GHz on one or two cores. What makes this processor interesting is that it is completely unlocked and can be overclocked via Intel’s XTU utility.
The rest of Intel’s 11th Core H Series core is presented in the tables above. The lowest end of the processor — the Core i5-11260H — has 6 cores / 12 threads, and as you progress along the stack, the number of cores / threads increases, along with the base and turbo boosters, culminating at the top — the end of the Core i9-11980HK.
The number of cores in the commercial line of CPUs based on Tiger Lake-Hu is similar, with similar clocks for the highest-ranking models. Some of these processors, however, carry the Xeon brand and target professional mobile workstations. In addition to brand differences, the commercial CPU line also supports support for Intel SIPP (Stable IT Platform Program) and Intel vPRO and Intel TXT (Trusted Execution Technology) technologies.
Intel Performance 11th generation Core H series
In terms of performance, Intel has released a handful of comparisons over older 10th generation processors and AMD’s latest 5000 series mobile series. Unlike the equivalent 10th Core X processors, the new 11th generation Core H series offers significant improvements in a range of games. Using the same titles in a similar comparison to the Ryzen 9 5900HX shows even greater benefits for the new 11th generation Core H series. Intel even claims that superior single-threaded performance, along with all platform improvements, allow the Core i5-11400H to outperform the AMD Ryzen 9 5900HS and in many games.
We hope to have an 11th generation Core i9-11980HK laptop in our hands soon, so we can do some of our own testing. Meanwhile, the updated platform with class-leading IO and the latest Intel CPU core seems to be a convincing upgrade over the previous generation, offering not only improved performance but also a range of new features.
