Intel · Core i5 · 2014 · FCBGA1168
The Intel Core i5-4278U is a mobile (laptop) processor with 2 cores, released in 2014. It is part of the Core i5 lineup, using the 4th Gen platform, and uses the FCBGA1168 package, which is soldered to the laptop's motherboard rather than socketed. Internally, it is built on the "Haswell-U" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 4 threads for improved parallelism. The Core i5-4278U has a base clock of 2.6 GHz and can boost up to 3.1 GHz depending on workload and thermal headroom. Intel manufactures the "Haswell-U" silicon on a 22 nm process node. This processor supports DDR3L/LPDDR3 memory. With a base TDP of 28W the Core i5-4278U is a balanced power envelope suited to mainstream laptops. Integrated graphics are provided by the Iris Graphics 5100 solution, so a discrete GPU is not required for display output. The cache hierarchy includes 3MB of L3 cache.
