Hirsch and Thraves can’t say too much but hint that Intel’s Ultra products will have “bigger feature sets” with “Arc-level graphics integrated into the processor that you won’t see on any products in the mainstream Core space,” AI capabilities (like AMD, Apple, and Qualcomm), and the “absolute best performance.”

Out of all these articles about this change, that's a better explanation of what distinguishes an "Ultra" processor, but it's still quite vague.
