- Tiger Lake-H
Last week Intel launched their Tiger Lake-H family of laptop processors. Aimed at the larger 14-inch and above laptops, this processor family is Intel’s newest offering for the high-performance laptop market, stepping in above Intel’s mobility-focused U and Y series of chips. Based on the same Tiger Lake architecture that we first became familiar with last year, Tiger Lake-H is bigger and better (at least where the CPU is concerned), offering up to 8 CPU cores and other benefits like additional PCIe lanes. Overall, Intel’s H-series chips have long served as the performance backbone of their laptop efforts, and with Tiger Lake-H they are looking to continue that tradition.
While last week was Tiger Lake-H’s official launch, as has become increasingly common for laptop launches, the embargoes for the launch information and for hardware reviews have landed on separate dates. So, while we were able to take about the platform last week, it’s only today that we’re able to share with you our data on TGL-H – and our evaluation on whether it lives up to Intel’s claims as well as how it stacks up to the competition.
Like Intel’s other laptop chips, Tiger Lake-H has multiple facets, with the company needing to balance CPU performance, GPU performance, and power consumption, all while ensuring it’s suitable to manufacture on Intel’s revised 10nm “SuperFin” process. Balancing all of these elements is a challenge in and of itself, never mind the fact that arch-rival AMD is looking to compete with their own Zen 3 architecture-based Ryzen 5000 Mobile (Cezanne) APUs.

Intel’s Reference Design Laptop: Core i9-11980HK Inside
For our Tiger Lake-H performance review, Intel has once again sent over one of their reference design laptops. As with the Tiger Lake-U launch last year, these reference design laptops are not retail laptops in and of themselves, but more of an advanced engineering sample designed to demonstrate the performance of the underlying hardware. In this specific case, the BIOS identifies that the laptop was assembled by MSI.
Wanting to put their best foot forward in terms of laptop performance, Intel’s TGL-H reference design laptop is, as you’d imagine, a rather high-end system. The 16-inch laptop is based around Intel’s best TGL-H part, the Core i9-11980HK, which offers 8 Willow Cove architecture CPU cores with SMT, for a total of 16 threads. This processor can turbo as high as 5.0GHz on its favored cores, a bit behind Intel’s previous-generation Comet Lake-H CPUs, but keeping clockspeeds close while making up the difference on IPC.
Unfortunately, their desire to put their best foot forward means that Intel has configured the CPU in this system to run at 65W, rather than the more typical 45W TDP of most high-end laptops. 65W is a valid mode for this chip, so strictly speaking Intel isn’t juicing the chip, but the bulk of the Tiger Lake-H lineup is intended to run at a more lap-friendly 45W. This gives the Intel system an innate advantage in terms of performance, since it has more TDP headroom to play with.
|Intel Reference Design: Tiger Lake-H|
|CPU||Intel Core i9-11980HK
8 Cores, 16 Threads
2600 MHz Base (45W)
3300 MHz Base (65W)
5000 MHz Turbo 2C
4500 MHz Turbo nT
|GPU||Integrated: Xe-LP Graphics
32 Execution Units, up to 1450 MHz
Discrete: NVIDIA GeForce RTX 3060 Laptop
30 SMs, up to 1703MHz
|DRAM||32 GB DDR4-3200 CL22|
|Storage||2x OEM Phison E16 512GB SSD (NVMe PCIe 4.0 x4)|
|Wi-Fi||Intel AX210 Wi-Fi 6E + BT5.2 Adapter|
|Power Mode||65 W
(Mostly tested at 45W)
Meanwhile the focus on CPU performance with TGL-H does come at a cost to integrated GPU performance. TGL-H parts include Intel’s Xe-LP GPU, but with only 32 EUs instead of the 96 found on high-end Tiger Lake-U systems. With TGL-H, Intel is expecting these systems to be bundled with discrete GPUs, so they don’t dedicate nearly as much die space to an integrated GPU that may not get used much anyhow. To that end, the reference system comes with an NVIDIA GeForce RTX 3060 Laptop graphics adapter as well, which is paired with its own 6GB of GDDR6.
Rounding out the package, the system comes with 32GB of DDR4-3200 installed. Storage is provided by a pair of Phison E16-based OEM drives, allowing Intel to show off the benefits of PCIe 4.0 connectivity for SSDs. Finally, Wi-Fi connectivity is also Intel-powered, using the company’s new AX210 adapter, which offers Wi-Fi 6E + BT5.2 on a single M.2 adapter. It’s worth noting that the AX210 is a fully discrete adapter, so it doesn’t leverage TGL-H’s integrated (CNVi) MAC, as that doesn’t support Wi-Fi 6E.
And, in keeping with making this reference system look as close to a retail design as reasonably possible, Intel even put the usual Intel Core and NVIDIA GeForce stickers on the laptop.
Unfortunately, we’ve had relatively little time with the system ahead of today’s embargo. The embargo on performance figures was originally scheduled for last Thursday (May 13th). However due to delays in shipping these laptops to reviewers, we didn’t receive the system until the end of last week, and Intel bumped back the embargo accordingly. So with just over two days to look over the system, we’ve really only had a chance to take a look at the most critical aspects of the system when it comes to performance.

danjw - Monday, May 17, 2021 - linkNo, not really. This is Intel's REFERENCE SYSTEM and it only trades blows with an AMD system that is a product. How is this competitive? You have to realize that the fans on this system aren't tuned for a consumer, they are tuned to make Intel's processor look better. If you read Andrei's conclusions, it is a processor for a laptop no one is selling anymore. It is a 65W processor battling a 35W processor.
Their are two reasons this may sell well. AMD's systems are still hard to find and the fact that many consumers still believe that the Intel Inside label is important.

Not to argue with your main point, but it's worth noting that even when Intel gets to design their own thermal solution, it still fell on its face @ the stock 65W settings. That's pretty bad.
mode_13h - Monday, May 17, 2021 - linkMaybe they should've had the team design it who rigged up that Cascade Lake workstation demo to run all cores at like 5 GHz. Sure, it'd have been the size of a briefcase and sounded like a leaf blower, but at least the it'd clock well!
Andrei Frumusanu - Monday, May 17, 2021 - linkJust to make it clear and visible: The i9-11980HK is advertised as a default 45W CPU. The fact that the system came in 65W mode shouldn't be seen as a "stock" behaviour of that SKU.

So, what are we to make of it? Was Intel trying to rig the benchmarks, then ???
jospoortvliet - Wednesday, May 19, 2021 - linkPfffif they were they did it in a stunningly incompetent way... haha
Spunjji - Thursday, May 20, 2021 - link@mode_13h - they did that with their previous Ice and Tiger Lake reference platforms (100% fan speed constantly, yes please) so it makes sense they did the same again here. 😬
morello159 - Monday, May 17, 2021 - linkAnother thing to consider is that Intel platforms have been much more stable, for me, than AMD. My ASUS G14 with the Ryzen 4900HS, for example, *can* deliver both outstanding battery life and amazing performance. However, there are often times when the system draws extra power for seemingly no reason. There are whole forums dedicated to tweaking the G14's power settings to fix high idle draw. I've also experienced some weird freezes, lockups, etc. It's a great laptop, but I wouldn't use it in a professional setting where I need it to work all the time.
My i7-10810U powered Dell Latitude 9510, while quite slow in comparison, gets 12 hours of battery life every time and can run days at a time without any hiccups.
Hifihedgehog - Monday, May 17, 2021 - link> "Intel platforms have been much more stable, for me, than AMD"
LOL. Even with Xe, I still see major graphical issues with 3D games which in some cases even refuse to render. It has gotten way better than five years ago, but AMD's graphic drivers are still far and away better. Stop reaching...
Spunjji - Tuesday, May 18, 2021 - linkThis reply doesn't really contradict morello159's main point, though.
I've had similar experiences - my 8th gen Intel Dell work system is rock solid, if unspectacular.
My 4800H + 5600M Dell gaming system has... issues. A lot of them appear to be Dell's fault, TBH, but not all of them are.
