<b>當您最需要時更高的效能</b> 當運作低於規格限制時，Intel®渦輪加速技術2.0可藉由提高操作頻率來加快處理器及圖形晶片效能的速度。最大頻率是依據工作負載、硬體、軟體及整體系統組態而改變。 2.0 Does not contain "conflict minerals": tantalum, tin, tungsten, and gold. Y 4th Generation Intel® Core™ processors are based on Intel® microarchitecture formerly known as Haswell, manufactured on 22 nm process technology with 3D tri-gate transistors. This platform provides excellent CPU, graphics, media performance, flexibility, and enhanced security over the 3rd generation Intel® Core™ processors, making it ideal for a broad range of intelligent systems.
