Intel's 35W Low-Power Rocket Lake Core i9-11900T & Core i7-11700T 8 core desktop CPUs have launched in the Asian and European markets but the US market has yet to get these chips. The low-power processors are designed for power-constrained OEM designs, SFF PC builds, and Mini-HTPC PCs.

The Intel 125W 'K' series and 65W 'Standard' chips have already been out since the 30th of March but only recently, retailers started selling 35W SKUs in the DIY segment. The 35W chips fall under the 'T' series branding and offer lower-power designs with conservative clock speeds compared to the standard 65W parts.
