Samsung is not quite done with Mobile World Congress yet. The Korean company today unveiled two new mobile processors, the octa-core Exynos 5422 and hexa-core Exynos 5260.
The Exynos 5422 is based on a big.LITTLE architecture with four ARM Cortex-A15 cores that can be clocked up to 2.1GHz and four ARM Cortex-A7 cores that can run up to 1.5GHz. Support for HMP (Heterogeneous Multi Processing) technology also allows the SoC to use any combination of its eight cores to deliver the most suitable performance.
The Exynos 5422 can support displays up to WQHD (2560×1440) and WQXGA (2560×1600) and video playback at up to 4K resolution. Samsung has also implemented new energy saving technologies called proprietary mobile image compression (MIC) and adaptive hibernation technology to reduce the energy demands of these high-resolution displays. Combined with the 28nm fabrication process node and HMP, power consumption is about 10% better than on similar chips based on a 32nm process.
Geared at the “mid- to high-end mobile market,” the Exynos 5260 comes with six cores: Two 1.7GHz Cortex-A15 cores and four 1.3GHz Cortex-A7 ones. It also uses the big.LITTLE HMP architecture and can support resolutions up to WQXGA (2560×1600). It also comes with an integrated video codec capable of handing Full HD playback at 60pfs with encoding and decoding of a number of standards, including H.264, MPEG4 and VP8.
Unlike some recent announcements (such as Qualcomm’s Snapdragon 610 and Snapdragon 615), neither of these new Samsung chipsets are based on a 64-bit architecture.
Samples of the Exynos 5422 are now available and mass production is slated to start later this quarter. It may well be the processor that ends up powering the octa-core variant of the Samsung Galaxy S5. As for the Exynos 5260, it is already in production.
