Intel introduces new Tiger Lake-H: 6 and 8-core 45W 10 nm processors for high end laptops

Intel is rolling out its Tiger Lake processors from the bottom up – starting with the 9/15W U-series in September, then the 28/35W H35 series in January and now the 45W top dogs of the H-series.

Tiger Lake is the name for Intel’s latest 10 nm processors. The U and the H35 series were limited to quad-core designs, the Tiger Lake-H models bring that up to 6 and 8 cores.

The top model is the is the Core i9-11980HK, Intel’s first unlocked 10 nm processor. It has eight cores (16 threads) and runs at a 2.6 GHz base clock speed at 45W. It can go up to 3.3 GHz at 65W. Again, those are base frequencies. The HK chip can reach 4.5 GHz in all-core turbo mode and peak at 5.0 GHz with two cores active.

All the other H-series processors run at 35/45W and offer lower clocks. Intel has split the line into two groups: a consumer line (including the HK model) and a commercial line (including a couple of Xeon W-11000M processors).

Here's the consumer line:

And the commercial line:

Tiger Lake-H promises a 19% higher performance per clock compared to the previous Comet Lake-H. Of course, Comet is a 14 nm design that is the nth refinement of Skylake from 2015. Intel’s previous 10 nm design, Ice Lake, topped out at 15W, so there’s no direct comparison.

The Tiger Lake-H processors are equipped with Intel Xe-LP graphics all with 32 execution units clocked at 1,450 MHz (except the base i5, which runs at 1,400 MHz). The processors have 20 PCIe 4.0 lanes for graphics and storage along with built-in Thunderbolt 4 controllers. They support DDR4-3200 RAM (but not LPDDR4, performance takes priority over power efficiency here).

Intel says that there are over 80 enthusiast designs based on the new Tiger Lake-H, some of which are being unveiled today.
