Laptop CPU Processors Core I5-5257U SR26K I5 Series (3MB Cache,up to 3.1GHz ) - Notebook CPU
The Core i5-5257U is a fast dual-core processor based on the Broadwell architecture, which has been launched in January 2015. With a TDP of 28 W, the CPU is suited for medium-sized ultrabooks and notebooks (MacBook Pro 13), whereas smaller devices will use more power efficient ULV models such as the Core i5-5200U (15 W TDP). In addition to two CPU cores with Hyper-Threading clocked at 2.7 - 3.1 GHz (2 Cores: 3.1 GHz as well), the chip also integrates an Iris Graphics 6100 GPU and a dual-channel LPDDR3-1866/DDR3L-1600 memory controller. The Core i5 is manufactured in a 14 nm process with FinFET transistors.
