So a 7840U in a 14" Thinkpad T14/T14s or HP EliteBook at 24W on TSMC 4 nm from about 3 years ago (May 2023) is about 70% faster in CBR15 sustained. And that is with a PL2 of only 28W.
While the more powerful processors from Intel's Panther Lake generation (e.g., the Core Ultra 9 386H) have already been extensively tested, we took a look at the Lenovo IdeaPad 5 2-in-1 14, which features a weaker but significantly cheaper entry-level model in the form of the Core Ultra 5 322. How does the six-core perform against its predecessors and AMD's competition?
