Intel at its recent 2021 International CES call confirmed the existence of an 8-core version of its 11th Gen Core "Tiger Lake" processor, and held the chip for the camera. The visibly bigger chip will be slated in Intel's H-segment (35 W to 45 W TDP), meaning it will only power gaming notebooks and mobile workstations; while the mainstream mobility segment will still be in the hands of its 4-core "Tiger Lake-H35" silicon. The 8-core "Tiger Lake-H" processor will also receive reasonably high clock-speeds, boosting up to 5.00 GHz.
Assuming the cache hierarchy and uncore/iGPU setup is unchanged between the 8-core and 4-core dies, we're looking at 24 MB of shared L3 cache, and 1.25 MB of dedicated L2 cache per core. These alone take up a big slice of the die-area. Add to this, the uncore features a PCI-Express Gen 4 root-complex and memory controllers that support dual-channel DDR4 and LPDDR4x memory types. The iGPU is expected to be based on the same Gen12 Xe-LP architecture as the 4-core die; although its execution unit count remains to be seen. In all likelihood, the 8-core "Tiger Lake-H" silicon is based on the same 10 nm SuperFin node.
