Intel’s 8-Core Mobile Tiger Lake-H, at 45 W, to Ship in Q1

January 12, 2021

Since the launch of Intel’s 11th Gen Core mobile processors, known as Tiger Lake, back in September, the hardware was noted for its core count. At a time where its competition were leveraging 8 cores in the same space, Intel seemed limited to only four, and in that 15-28 W power window. At the time, Intel stated that the base Tiger Lake design was aimed to be scalable, and that double sized variants were in the works. Today Intel has confirmed that those double-sized parts will be coming in Q1, in the form of Tiger Lake-H.

Back at Intel’s Architecture Day 2020, lead architect Boyd Philips stated that even though the standard Tiger Lake UP3 design contained four cores and 12 MB of L3 cache, designs with double the L3 cache were in the works. This was instantly interpreted that double core-count versions of Tiger Lake were in the works, given that the higher-powered mobile processor line-up had been left to older 14nm processors to fill the gap, given that Intel normally launches products for both 15 W and 45 W at the same time. We had been expecting a fast follow on, with a launch sometime later in Q3, but it would appear that Intel has pushed this out to Q1. Intel says that these processors will start production and ship in Q1, which likely means that the actual products will come to market in Q2.

Intel has confirmed that these parts will offer eight cores and sixteen threads, with a highlight being that the top variants will enable 5.0 GHz turbo frequencies on multiple cores. These processors will also have 20 lanes of PCIe 4.0, which will allow for a full PCIe 4.0 x16 link to a discrete graphics card and a single PCIe 4.0 x4 storage drive at the same time, while also having a separate link for the chipset and IO. We expect these processors to also support Resizable BAR. These processors will also have Thunderbolt 4 native support, as well as Wi-Fi 6/6E support through an associated RF module.  

Intel traditionally has a number of overclockable H-series processors, known as HK, however the company has not explicitly stated if any overclocking SKU will make it to market. Typically these H-Series processors target the 45 W market, with a 35 W step-down option. Intel is also announcing today that it has moved its U-series processors, typically 15 W, up into that 35 W market as well (known as H35). We will start to see some overlap between the two, with higher frequency quad-core U-series processors up against eight-core H-series parts.

We wait to see exactly what specifications Intel will target with the new hardware. More detail to come.
