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.

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.

Power Consumption - Up to 65W or not?

    Of course. It must be some kind of dark conspiracy to hide the real compiler settings. The truth is out there! Trust no one! Reply

    Andrei, TGL-U (UP3/UP4/H35) LPDDR4/X is actually 8x16. Two memory controllers, each with four x16 channels. Reply

    Yes, brainfart. Reply

    Wow!

    So, how are they mapped? How much interleaving, and at what granularity?

    Incidentally, I have a Phenom II motherboard that allows me to configure page-granularity interleaving. Not sure how common it is, but I don't think my Intel workstation board gives me that option! Reply

    Doesn't sound like a good CPU benchmark to me. Reply
  • mode_13h - Monday, May 17, 2021 - link

    So, you want a suite of benchmarks that all behave similarly and don't stress the platform in various and different ways?

    Suit yourself, but I think a good benchmark suite should have enough diversity to hit different edge cases, as long as it's not doing anything unrealistic. And, as far as I can tell, the SPEC 17 tests are entirely comprised of real-world programs.

    Interesting how much power Tiger Lake H needs to draw to be competitive with Cezanne. At this point it's clear that Intel's big cores are bloated when AMD has higher IPC and frequency at lower power draw with a comparable node. Little cores in Alder Lake may help with efficiency, but they are taking power budget away from the big cores which hurts their frequency. Intel probably needs to redesign their big cores from the ground up rather than continuing to refine and improve Pentium-M.

    On a side note I'm conflicted on your decision to omit AVX-512 on NAMD. On one hand you are not testing AVX-512, but on the other hand you are omitting a possibly real world scenario for someone. Intel's marketing on AVX-512 and its inclusion in consumer processors are questionable choices, but that still is a valid, functional feature built into the chip. Perhaps a good compromise would be to add in the updated version for AVX-512 processors only.

    Most workloads that can run avx256 can easily be extended to AVX-512. In some cases, you need just to recompile with AVX-512 optimization floag on. Even Skylake-X and cascadelake-X there is a noticeable improvement in performance in AVX-512 Reply
