Samsung Exynos 7884B vs Qualcomm Snapdragon 845 vs Qualcomm Snapdragon 850

Samsung Exynos 7884B

The Samsung Exynos 7884B (also called Exynos 7 Series) is a upper mid-range system-on-a-chip (SoC) for smartphones and tablets. It integrates two big ARM Cortex-A73 cores clocked at up to 1.56 GHz. Furthermore, there are six power efficient Cortex-A53 cores at up to 1.35 GHz, an ARM Mali-G71 MP2 GPU and a LPDDR4x memory controller. Compared to the faster Exynos 7885, the CPU cores of the 7884B are clocked clearly lower. Furthermore, the integrated LTE modem is also slower (150 / 50 Mbit download / upload). 802.11ac WiFi, Bluetooth 5.0 and FM Radio are also in the chip. It is manufactured in 14nm FinFET at Samsung and therefore a rather power efficient SoC.

Qualcomm Snapdragon 845

The Qualcomm Snapdragon 845 Mobile Platform (or SD845) is a high-end SoC for smartphones that was introduced in early 2018 and manufactured in 10 nm LPP FinFET at TSMC. Integrates 4x Kryo 385 cores (Cortex-A75) at up to 2.8 GHz (max) for performance and 4x Kryo 385 at 1.8 GHz (max) for efficiency. Furthermore offers an X20 LTE modem (Cat. 18 1.2 Gbps downlink, Cat 13 150 Mbps uplink), ac-WiFi and a dual-channel 32-Bit 1866 MHz LPDDR4x memory controller.

Qualcomm Snapdragon 850

The Qualcomm Snapdragon 850 Mobile Compute Platform (or SD850) is a ARM based SoC for Windows laptops. It is a higher clocked version (3 versus 2.8 GHz) of the Snapdragon 845 for smartphones and also manufactured in 10 nm LPP FinFET at TSMC. It integrates 4x Kryo 385 cores (Cortex-A75) at up to 2.95 GHz (max) for performance and 4x Kryo 385 (at 1.8 GHz?) for efficiency. Furthermore offers an X20 LTE modem (Cat. 18 1.2 Gbps downlink, Cat 13 150 Mbps uplink), ac-WiFi and a dual-channel 32-Bit 1866 MHz LPDDR4x memory controller.

The performance of the Snapdragon 850 in Windows is in theory similar to a Intel Core i5 of the Y-series (e.g. Core i5-7y54). However, this is only the case for native ARM64 compiled applications and games. 32-bit applications that are not compiled for the ARM architecture only run in an emulation and perform much worse (e.g. see Cinebench R11.5 benchmark). 64-bit Intel/AMD apps are not supported at all.

The chip is very power efficient as its produced at TSMC in the modern 10nm LPP process. Therefore, laptops using the Snapdragon 850 can be passively cooled (no fan) and should not throttle under constant load.
