Qualcomm Snapdragon 8cx Gen 3 vs Qualcomm Snapdragon 888 Plus 5G

Qualcomm Snapdragon 8cx Gen 3

The Qualcomm Snapdragon 8cx Gen 3 Compute Platform is an ARM based SoC for Windows laptops. It integrates four big ARM Cortex-X1 performance cores (up to 3 GHz) and four smaller ARM Cortex-A78 with up to 2.4 GHz.

The Compute Platform also integrates a Snapdragon X62 5G modem with up to 10 Gbps download and 316 Mbps upload. The integrated WLAN modem supports Wi-Fi 6E (2x2) and the satellite positioning system supports BeiDou, Galileo, GLONASS, GPS, QZSS, and SBAS. The integrated video engine supports H.264, H.265, and VP9 decoding in 4K 120fps.

The performance should be around 85% faster for the CPU and 60% faster for the GPU compared to the previous generation (Snapdragon 8cx Gen 2).

The chip is produced in the modern 5nm process at Samsung (5LPE) and designed for fanless laptops (7 to 9 Watt TDP range).

Qualcomm Snapdragon 888 Plus 5G

The Qualcomm Snapdragon 888+ (Plus) 5G Mobile Platform is a high-end SoC for smartphones that was introduced in mid 2021 and manufactured in 5 nm at Samsung. 

Integrates one “Prime Core” based on a ARM Cortex-X1 architecture clocked at up to 3 GHz. Three more performance cores are based on the A78 but clock up to 2.42 GHz. Furthermore, four energy saving cores are integrated that are based on the ARM Cortex-A55 architecture and clock at up to 1.8 GHz. In addition to the processor cores, the SoC integrates a WiFi 6e modem, a Hexagon 780 DSP (up to 26 TOPS of AI performance) and a Spectra 580 ISP. The integrated memory controller now supports faster LPDDR5 memory with up to 3,200 MHz. 5G is now included in the chip with the Snapdragon X60 modem.

Compared to the older Snapdragon 888, the 888+ offers a slightly higher clocked prime core (+160 MHz) and a 23% faster Hexagon 790 DSP. Therefore, it is now the fastest Android SoC (at the time of announcement), but still slightly slower (CPU and GPU) than the Apple A14 and A15 Bionic SoCs.
