Intel Announces 11th Gen Core “Tiger Lake-H” Mobile Processors

Intel today announced the 11th generation Core “Tiger Lake-H” mobile processors for notebooks of conventional thickness, gaming notebooks, and mobile workstations. This is the first scale-up of the “Tiger Lake” microarchitecture, with the introduction of a brand new die that has up to 8 “Willow Cove” CPU cores. These processors typically come with TDP of 35-45 W, but the flagship part ships with TDP as high as 65 W. Unlike “Rocket Lake,” this chip is built on Intel’s latest 10 nm SuperFin silicon fabrication process. With it, Intel is announcing ten processor SKUs—five each for the consumer and commercial notebook market segments. These span across the Core i9, Core i7, and Core i5 brand extensions.

The 10 nm “Tiger Lake-H” silicon measures roughly 190 mm², and has several changes compared to the 4-core “Tiger Lake-U” silicon the company debuted the 11th Gen with. The biggest change is the CPU core count of 8. This lets it not only achieve parity with AMD in mobile CPU core counts but also purportedly beat it on the back of a higher IPC. Each of these 8 “Willow Cove” cores has 1.25 MB of dedicated L2 cache and shares 24 MB of L3 cache. You get the same “Willow Cove” ISA as the “Tiger Lake-U,” including AVX-512 and DLBoost. Next up, the chip features integrated graphics based on the Gen12 Xe LP graphics architecture, only that the execution units have reduced to just 32 on this silicon, compared to 96 on the 4-core Tiger Lake-U. The new chip enjoys a bigger power budget to run the iGPU at higher clock speeds. There is also a 20-lane PCI-Express Gen 4.0 interface, and a dual-channel DDR4 memory controller.

Leading the pack is the Core i9-11980HK, targeted exclusively at gaming notebooks. This chip ticks at 3.30 GHz (nominal), and can boost up to 5.00 GHz, with up to 1.45 GHz iGPU frequency. The chip is also unlocked, and has many of the same overclocking features as the desktop Core i9-11900K. Next up in the Core i9 series is the i9-11900H, with much lower 2.50 GHz nominal clocks, but up to 4.90 GHz boost, and the same 1.45 GHz iGPU clocks. The Core i9 parts feature Turbo Boost Max 3.0 boosting algorithm.

The Core i7 series is differentiated from the Core i9 with an apparent lack of Turbo Boost Max 3.0. These are still 8-core/16-thread chips with the full 24 MB of L3 cache. The Core i7-11800H is clocked at 2.30 GHz with a 4.60 GHz max boost. Next up are the 6-core/12-thread Core i5 series, which surprisingly feature just 12 MB of L3 cache (and not the expected 18 MB, going by the 3 MB/core convention for Tiger Lake). The Core i5-11400H is clocked at 2.70 GHz, with up to 4.50 GHz boost, while the i5-11260H does 2.60 GHz with up to 4.40 GHz boost. Both these feature lower 1.40 GHz max iGPU clocks. It’s interesting to note here, that Intel isn’t branding the Xe LP iGPU under the Iris Xe series, but rather the UHD 750 series.

The commercial SKUs are available only in notebooks that are sold in bulk to large corporations. These include the Core i9-11950H, the i7-11850H, and the i5-11500H, which each feature about 100-200 MHz higher clocks than the i9-11900H, i7-11800H, and the i5-11400H, respectively. There’s also the addition of the Xeon W-11955M and the Xeon W-11855M, which feature ECC memory support. All these commercial SKUs feature Intel vPro, Trusted Execution technology, and SIPP. The commercial chips also feature Intel CET (control-flow enforcement technology), which thwarts a class of side-channel attacks; and the Threat Detection Technology (silicon-based AI threat detection).

As for performance, Intel claims to have comprehensively beaten the previous-generation Core i9-10980HK “Comet Lake-H,” as well as the AMD Ryzen 5900HX “Zen 3” processor, claiming significant gaming performance gains, as well as CPU performance gains in the near double-digits, based the higher IPC of “Willow Cove,” combined with core-count parity, and a lavish power budget to go with the 10 nm SuperFin process.

The platform and I/O have a handful of improvements. You get PCI-Express 4.0 x16 graphics and a CPU-attached PCI-Express 4.0 x4 for an M.2 NVMe slot. The x16 slot can be further segmented into x8/x4/x4 or even x12/x4, so additional CPU-attached M.2 slots can be created for NVMe RAID, or for CPU-attached Thunderbolt 4 controllers. DDR4-3200 is natively supported, although notebook vendors have the freedom to push memory frequencies higher. The chipset bus has been fattened and is DMI 3.0 x8 (physically PCI-Express 3.0 x8). The 24 lanes put out by the chipset are Gen 3. Besides Thunderbolt 4 (40 Gbps), the I/O includes MIPI SoundWire audio, Optane H20, Wi-Fi 6E (Gig+), and 2.5 GbE wired networking.
