grade, TEC (Typical Energy Consumption), and product category presented on the label are determined and calculated according to the standard GB28380-2012. 1. Energy Efficiency Grades The grade is determined by the standard with the calculation of base consumption level with the sum of all the allowances for additional components such as main memory and graphics card. For products of any grade, the TEC should not exceed the value specified in the following table: Product Type Desktop microcomputer, AIO Category A Category B Category C Category D Portable Computer Category A Category B Category C TEC (kilowatt hour) Grade 1 Grade 2 98.0+∑Efa 148.0+∑Efa 125.0+∑Efa 175.0+∑Efa 159.0+∑Efa 209.0+∑Efa 184.0+∑Efa 234.0+∑Efa 20.0+∑Efa 35.0+∑Efa 26.0+∑Efa 45.0+∑Efa 54.5+∑Efa 75.0+∑Efa Grade 3 198.0+∑Efa 225.0+∑Efa 259.0+∑Efa 284.0+∑Efa 45.0+∑Efa 65.0+∑Efa 123.5+∑Efa NOTE: ∑Efa is the sum of power factor of product additional functions. 2. Typical Energy Consumption The energy consumption figure presented on the label is the data measured with the representative configuration that covers all the configurations in the registration unit which is selected according to CEL-30. Thus, actual energy consumption of this specific microcomputer may not be the same as the TEC data presented in the label. 3. Product Category The product category is determined by the standard according to the microcomputer's configuration. The categorization of products complies with the regulations in the following table: Product Type Category A Category B Category C Category D Configuration Description Desktop microcomputer, AIO Portable Computer The desktop microcomputer and AIO whose configuration is out of the scope of Category B, C, and D The portable computer whose configuration is out of the scope of Category B and C CPU physical core number of 2, and system memory of not less than 2GB A Discrete GPU CPU physical core number of over 2, with at least one of the following features: 1. System memory of not less than 2 GB The product that has a CPU physical core number of not less than 2, system memory of not less than 2GB, A Discrete GPU with Frame Buffer Width not less than 128-bit. 2. A Discrete GPU CPU physical core number of not less than 4, with at least one of the following features: 1. System memory of not less than 4 GB 36 Chapter 5 Environmental notices for notebook computers
