Qualcomm Snapdragon 845 Octa Core Kryo 385 SoC to Power Premium Smartphones, XR Headsets, Windows Laptops

Qualcomm Snapdragon 845 processor was expected since May 2017 with four custom Cortex A75 cores, four Cortex A53 cores, Adreno 630 GPU, and X20 LTE modem. with the launch planned for Q1 2018. At least, that what the leaks said. Qualcomm has now formally launched Snapdragon 845 Mobile Platform and rumors were mostly right, as the the octa-core processor comes with four Kryo 385 Gold cores (custom Cortex A75), four Kryo 385 Silver cores (custom Cortex A55) leveraging DynamIQ technology, an Adreno 630 “Visual Processing System”, and Snapdragon X20 modem supporting LTE Cat18/13. The processor is said to use more advanced artificial intelligence (AI) allowing what the company calls “extended reality (XR)” applications, and will soon be found in flagship smartphones, XR headsets, mobile PCs, and more. Qualcomm Snapdragon 845 (SDM845) specifications: Processor 4x Kryo 385 Gold performance cores @ up to 2.80 GHz (custom ARM Cortex A75 cores) 4x Kryo 385 Silver efficiency cores @ up to 1.80 GHz …

ARM Cortex-A75 & Cortex-A55 Cores, and Mali-G72 GPU Details Revealed

We’ve already seen ARM Cortex A75 cores were coming thanks to leak showing Snapdragon 845 SoC will feature custom Cortex A75 cores, but we did not have many details. But since we live in a world where “to leak is glorious”, we already have some slides originally leaked through VideoCardz with the post now deleted, but Liliputing & TheAndroidSoul got some of the slides before deletion, so let’s see what we’ve got here. ARM Cortex A75 So ARM Cortex-A75 will be  about 20% faster than Cortex A73 for single thread operation, itself already 30% faster than Cortex A72. It will also be the first DynamIQ capable processor together with Cortex A55 with both cores potentially used in big.LITTLE configuration. Cortex A75 performance is only better for peak performance, and remain the same as Cortex-A73 for sustained performance. The chart above does not start at zero, so it appear as though there are massive performance increases, but looks at the number …

ARM DynamIQ Improves on big.LITTLE Technology, Supports Up to 8 Heterogeneous Cores in a Single Cluster

ARM unveiled big.LITTLE technology in 2011 which consisted of clusters of low power cores such as Cortex A7 or A53, and high performance cores such as Cortex A15 or A72, with the system assigning tasks to the best processor for the job in order to  optimize battery life. big.LITTLE supports up to 4 cores per cluster, and you can mix different types of cores within a single cluster. ARM DynamIQ changes all that as up to 8 cores are supported within one cluster, and you can mix low power and high performance cores within a given cluster. ARM DynamIQ multicore microarchitecture will be available for all new ARM Cortex-A processors starting this year, and targets automotive, networking, server, and primary compute devices. ARM claims it’s especially advantageous for artificial intelligence due to better performance, and autonomous driving due to increased safety, and it allows for much faster response from accelerators. Based on the slide below showing the evolution of multi-core …
