Apple seems to be using custom Intel Ice Lake SKUs for its new 13-inch MacBook Pro with a higher base clock and base TDP. The high-end model of the new 13-inch MacBook Pro is the only tier that got the new 10th generation Intel processors.

As noted by AnandTech, Apple is using a custom Ice Lake SKU from Intel, which is not listed on the company’s website.
