Samsung has a new octacore-soc in Exynos-line announced that to be produced on 20nm. The Exynos 5430 features a combination of Cortex A15 and Cortex A7 cores, and is used in the recently announced Galaxy Alpha smartphone.
As with previous octacores from Samsung uses two processorclusters: four powerful Cortex A15 cores at 1.8 GHz and four efficient Cortex A7 cores at 1.3 GHz. That can individually be turned on or off, depending on how heavy the soc is charged. On gpu-just chose Samsung again for the Mali T628-design of the ARM and the total memory bandwidth of the soc amounts to 17GB/s. That probably means that the maximum memory speed jacked up to 1066MHz and Samsung still a dualchannel-32bit-bus is used.
The Exynos 5430 is the first system-on-a-chip that Samsung at 20nm-hkmg-process manufacturing; used until now, the Korean manufacturer a 28nm-hkmg-process. According to Samsung, the new process, a power saving of 25 per cent, assuming that the chips for the rest are identical. It is expected that with competitor TSMC, chips makes for Qualcomm, also soon to be the first 20nm chips of the tyre will roll.
Samsung lays strong emphasis on the multimediacapabiliteit of the soc. So there is hardware support for decoding of the hevc/h265 codec, which is used to encode 4k images. That kind of material can be according to Samsung is outputted to the hdmi input of a uhd-tv. Furthermore, panel self refresh is supported, allowing the soc to the display of static images, not a constant stream of new frames to the screen need to send. That need for energy saving ensure.
The first phone where the Exynos 5430, Samsung Galaxy Alpha, a new member in the Galaxy line, with a partly metal housing. It was earlier this week announced and should be sometime in september in the Benelux come true.
