Features
Intel first described Tiger Lake and Willow Cove during their Architecture Day in 2020.
Willow Cove is almost identical to the previous microarchitecture but introduces new security features, a redesigned cache subsystem, and higher clock speeds.
Intel claims that these changes, in addition to the new 10SF process node, give an additional 10–20% performance increase from Sunny Cove.
