RoHS stands for Restriction of Hazardous Substances. RoHS, also known as Directive 2002/95/EC, originated in the European Union and restricts the use of specific hazardous materials found in electrical and electronic products (known as EEE). All applicable products in the EU market after July 1, 2006 must pass RoHS compliance. The substances banned under RoHS are lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and four different phthalates (DEHP, BBP, BBP, DIBP). RoHS <b>Higher Performance When You Need It Most</b> Intel® Turbo Boost Technology 2.01 accelerates processor and graphics performance by increasing the operating frequency when operating below specification limits. The maximum frequency varies depending on workload, hardware, software, and overall system configuration. 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.
