Samsung has officially announced a new Exynos octa-core processor that uses a new 20nm manufacturing process. The Exynos 5430 chip, which can be found in the Samsung Galaxy Alpha, is the first Exynos processor to switch to a 20nm manufacturing process. The new 20nm manufacturing process results in a smaller die than a traditional 28nm process, resulting in up to a 25 percent decrease in power consumption.
In other areas, the Exynos 5430 is similar to existing octa-core chips. It features four 1.3GHz Cortex A7 cores and four 1.8GHz Cortex A15 cores on a big.LITTLE HMP set-up. This means that while the processor will usually choose one set of cores to run on at a time, it can run both at the same time if necessary. Such a processor is quite capable of powering devices with high resolutions like QHD and WQXGA. Additionally, the Galaxy Note 4 has been rumored to use an Exynos 5433 processor, which could also use this 20nm process and be a more powerful version of the Exynos 5430.
