On the laptop side of things, Tiger Lake-H 45 W will debut for high-end gaming and content creator laptops in Q2 2021. A year later, in Q2 2022, Alder Lake-H 55 W with 32 EUs of Xe Gen12, up to 8+8 24 threads, and support for PCIe Gen5 and DDR5 is expected. Interestingly, Tiger Lake-H will also have a 35 W variant that may launch sooner than the 45 W part with possible support for LPDDR5 RAM. In Q2 2022, Alder Lake will have a 45 W SKU as the lower power variant with 6+8 20 threads and a 96-EU Xe Gen12.
It could be that Intel is looking to increase the TDP ratings by about 10 W with Alder Lake to possibly accommodate the hybrid core architecture while also giving OEMs more turning leeway to enable thin and light designs.
We already know that AMD will be announcing H-series Cezanne and Lucienne APUs at CES next year. While Cezannne is a Zen 3 part, Lucienne is a Renoir Refresh with SMT enabled. From what we know so far, Cezanne will stick to using Vega GCN cores for graphics. Rembrandt-H APUs slated to launch in Q1 2022 will mark a shift to RDNA2 iGPUs and may top-out as 8C/16T parts.
Rembrandt-H is essentially a Zen 3 refresh but made on a 6 nm process bringing support for DDR5/LPDDR5 RAM at 45 W. Rembrandt is also speculated to launch with support for Computer Vision Machine Learning (CVML) for better onboard AI capabilities. A Cezanne Refresh may complement Rembrandt-H in 2022, but that is still unclear for now.
