Qualcomm Snapdragon 8 Gen 1 vs Qualcomm QCM6490

Qualcomm Snapdragon 8 Gen 1

The Qualcomm Snapdragon 8 Gen 1 Mobile Platform is a high-end SoC for smartphones that was introduced in late 2021 and manufactured in 4 nm at Samsung. Integrates one “Prime Core” based on a ARM Cortex-X2 architecture clocked at up to 3 GHz. Three more performance cores are based on the Cortex-A710 but clocked up to 2.5 GHz. Furthermore, four energy saving cores are integrated that are based on the ARM Cortex-A510 architecture and clocked at up to 1.8 GHz. All cores can use the shared 6 MB level 3 cache.

Compared to the Snapdragon 888 (Plus), the CPU part gains 20% performance and 30% power savings according to Qualcomm. This means that the Snapdragon 8 Gen 1 is the fastest CPU for Android based smartphones and should be positioned between the Apple A13 and A14 CPU.

The integrated AI Engine can offer up to 4x faster AI performance thanks to the bigger Tensor engine. The 18-Bit-Spectra-ISP also saw some big improvements and is now called Snapdragon Sight.

The integrated Adreno 730 offers a 30% graphics boost compared to the previous Adreno 660.

The integrated Snapdragon X65 5G modem is also new and offers faster transfer rates (up to 10 Gbps download and 3 Gbps upload). The FastConnect 6900 offers support for the current Wifi 6E and Bluetooth 5.2.

Qualcomm QCM6490

The Qualcomm QCM6490 is an upper mid-range SoC and is based on the Snapdragon 778G, but this variant is an extended-life chipset. The QCM6490 is being used for the first time in the Android smartphone Fairphone 5, but has actually been designed for corporate use and IoT applications.

The Kyro 670 CPU consists of a total of eight cores, which are divided into three clusters. The first cluster consists of just one high-performance core (Kyro Gold Plus, Cortex-A78), which operates at up to 2.71 GHz. The second cluster contains three further Cortex-A78 cores (Kyro Gold), each clocking at up to 2.40 GHz. The remaining four power-saving cores (Kyro Silver, Cortex-A55) are located in the last cluster and operate at up to 1.96 GHz. For the graphics calculations, an Adreno 643 with 812 MHz is integrated.

The QCM6490 SoC has an integrated 5G modem that supports both 5G-Sub6 and 5G-mmWave. In theory, this enables data rates of up to 3.7 Gbit/s downlink and 2.5 Gbit/s upload. Wi-Fi 6E is also on board, which supports the 6 GHz band.

The SoC is manufactured using the 6 nm process.
