The specifications of Intel’s Alder Lake low-power T-series processors have surfaced. Although they’re largely identical to the standard 125W/65W SKUs, there are a few differences other than the lower TDP (35W). For example, the efficiency cores are limited to the two fastest SKUs which is rather ironic considering these are meant for low-power/mini-ITX systems.
