Intel is strongly committed to the laptop market, since it is where it is found in bulk of the buyers of new PCs. That is why they bet with its Tiger Lake-H, a version with more cores of its Tiger Lake designed for the market enthusiast, both gaming and professional.
Intel claims to have gotten its Tiger Lake-H CPU to be in 80 different models of laptops for this year and to have a production of it much higher than that of its rival AMD. But what secrets does the Tiger Lake-H hide?
Willow Cove. the core of the Tiger Lake-H
Willow Cove It is a slightly improved version of the Sunny Cove core used in the Intel Ice Lake and which has been built under Intel’s 10nm SuperFin node. Thanks to this and according to Intel the Tiger Lake-H becomes the CPU for laptops with the highest performance in a single thread and that brings a 19% improvement in multithreading compared to Intel Core Gen 10 CPUs for laptops.
Willow Cove also incorporates AVX-512 units inside, with the same instruction sets also included in Rocket Lake-S and therefore with improvements in fields such as cryptography and artificial intelligence in those applications that are optimized for AVX-512.
Intel Tiger Lake-H, designed for overclocking
Tiger Lake-H is a CPU that Intel created for gaming laptopsThis is noticeable due to its improvements for overclocking, where manual control of the core-by-core voltage is now possible, apart from having better features XTU for manual overclocking and internal BCLK option. Also thanks to Intel Speed Optimizer all cores are set at the highest possible clock speed in unison, which improves multithreaded performance.
In the event that what has to be accelerated are the cores for single-threaded tasks, the Intel Turbo Boost Max 3.0 what it does is identify the cores that can reach higher speeds and uses them to speed up those tasks.
New form factors for Tiger Lake-H
The great novelty of the new Tiger Lake-H is the launch of 35W TDP CPUs, which allows for thinner and lighter laptops, but without sacrificing performance for gaming. How fine? Well, Intel tells us about notebooks less than 20mm thick without sacrificing power for gaming.
In the same way that the 35 W TDP is designed to make thinner gaming PCs, it also serves to deliver extra power to other elements that need it, such as the GPU, which in a gaming laptop is always limited by that aspect.
I / O on Tiger Lake-H
We could come to think that with a finer form factor that power has been sacrificed, but it is not like that. Since Intel has equipped the Tiger Lake-H with up to 44 PCI Express lanes, 20 of which are fourth generation, allowing notebook PC manufacturers and builders to add a dedicated GPU for gaming, be it an NVIDIA RTX, an AMD RX 6000 or Intel’s future Intel Xe-HPG. The other 24 are PCI Express 3.0.
But not only on PCI Express do laptops live, being another of the improvements that have incorporated its new WiFi module, called Intel Killer Wi-Fi 6E, based on radio AX1675. Which is backward compatible with standards IEEE 802.11ax (Wi-Fi 6) and 802.11ac (Wi-Fi 5) thanks to being able to operate at 5 GHz. On a Wi-Fi 6E network, the new Intel radio switches the network to 6 GHz but it is still based on the 802.11ax protocol but with the improvements that it provides to operate at 6 GHz, among other things the power overcome the barrier of Gigabit per second via WiFi.
Another of the improvements that Intel has integrated is support for Thunderbolt 4 integrated as standard in the processor. Which uses USB-C connectors, but with a bandwidth of up to 40 Gbps, twice that of conventional USB 3.2.
What is the performance of these CPUs?
According to data from Intel itself and after comparing a Intel Core i9-11980HK with its direct predecessor, the i9-10980HK, on a PC with the same with the same GPU we can see an increase in performance between 5% obtained in Far Cry New Dawn and 21% in War Thunder. The GPU used for the test is a NVIDIA RTX 3080 Mobile and the system TDP is the same in both cases, 155 W.
Intel is not content with comparing itself to itself. The direct rival of these Tiger Lake-H are the AMD Ryzen 5000 SoCs. That is why they have compared their Intel Core i9-11980HK vs AMD Ryzen 9 5900HS. Both are the two most powerful gaming CPUs that we know will be coming out this year for laptops.
The differences? The slightest in the Total War: Three Kingdoms where the Intel CPU takes 11% performance on average, the most exaggerated is that of Grid 2019 with a difference of 26%. Again an NVIDIA RTX 3080 Mobile is used again, but this time the consumption is of 165 W for the laptop with the AMD CPU and 155 W for the Intel one.
But where Intel takes its pride the most is with its Intel Core i5-11400, which has a performance close to that of the Ryzen 9 5900HS. In some cases it is 3 points below and in others it can reach an additional 12 points. All this using an RTX 3060 in both PCs, but with 80 W of consumption in the PC with AMD CPU and 65 W in the case of the Intel laptop and with a thickness of less than 20 mm.
Intel Tiger Lake-H CPUs
Intel is launching a total of 6 different models within the Tiger Lake-H range. Which go in 6 and 8 core configurations. All supporting DDR4 up to 3200 MHz, a TDP of 35 W and with an integrated 32 EU Intel Xe CPU.
Beyond the gaming market
The other novelty that Intel has presented are its Tiger Lake-H CPUs for the commercial market. We also have six models in total, where the model that stands out the most is the Intel Xeon WW-11955M, which has support for ECC memory.
The differences with the gaming versions? Out-of-the-box support for technologies such as Intel SIPP, Intel VPro and Intel TXT. Which are key technologies for use in business and corporate environments. Virtualization technologies are one of its main advantages and have no equivalent in AMD, so Intel is once again ensuring its dominance in the enterprise market.
In terms of performance, Intel claims an improvement ranging from 24% to 75% compared to the company’s previous corporate processors. Specifically in the comparison between the i9-11950H and the i7-9850H. so Intel not only seeks to consolidate its leadership in gaming laptops but also in those that professionals of all kinds use to work.
