Intel cites 10nm's clock speeds, which were initially woefully inadequate at 4.1 GHz, as the primary reason it chose to backport Sunny Cove to create the Cypress Cove architecture present in the Rocket Lake chips. Sunny Cove, which debuted with the 10nm Ice Lake mobile processors, would be the first 'portable' architecture. Intel Core i9-11900K at Amazon for $469.91 (opens in new tab)Īt its Architecture Day 2018, Intel announced that it would decouple its architectures from specific process nodes, making them portable between nodes so the company could select the best process for each application, and also have a buffer to better absorb any future process node delays.ABT is the company's fourth boost tech, but it only offers the new feature on its pricey Core i9 K and KF processors. In a nutshell, ABT allows Core i9 processors to opportunistically boost to higher all-core frequencies based upon available thermal headroom and electrical conditions. Think of Intel's Adaptive Boost Technology (ABT) much like a dynamic auto-overclocking feature that applies to all-core boosts, but remains within warranty. This feature doesn't have a guaranteed boost threshold - it will vary based on chip quality, your cooler, and power delivery. Adaptive Boost Technology: Allows dynamic adjustment of all-core turbo frequencies when four or more cores are active.All-Core Thermal Velocity Boost: Increases all-core frequency when all cores are active and the chip is under 70C.Single-Core Thermal Velocity Boost: Fastest active favored core can boost higher than Turbo Boost Max 3.0 if below a pre-defined temperature threshold (70C) and all other factors adhere to TB 3.0 conditions. Chip must be below power, current, and temperature specifications. Turbo Boost Max 3.0: Fastest cores are identified during binning, then the Windows scheduler targets the fastest two active cores (favored cores) with lightly-threaded applications.Turbo Boost 2.0: Increased frequency if chip operates below power, current, and temperature specifications.
