Qualcomm Snapdragon 870 5G vs Mediatek Helio G85 vs Qualcomm Snapdragon 865
Qualcomm Snapdragon 870 5G
► remove from comparison
The Qualcomm Snapdragon 870 5G Mobile Platform (SM8250-AC) is a high-end smartphone and tablet SoC that Qualcomm announced in mid 2021. The SoC integrates a fast ‘Prime Core’ that clocks up to 3.2 GHz and three additional ARM Cortex-A77 performance cores, which can reach up to 2.42 GHz. These are complemented by four power-saving ARM Cortex-A55 cores that clock up to a maximum of 1.8 GHz. Compared to the similar and older Snapdragon 865+, the Prime Core clocks 100 MHz faster and the GPU is slightly higher clocked.
Therefore, the Snapdragon 870 is slightly faster than the old Snapdragon 865 and 865 Plus and slots in behind the high end Snapdragon 888.
The Mobile Platform integrates a Qualcomm X55 5G modem with Sub-5 and mmWave support and global 5G bands with up to 7.5 GBit/s (download) speed. The SmartConnect 6800 modem supports Wi-Fi 6 with 8x8 MU-MIMU and 60 GHz 11ay up to 10 Gbps.
The integrated GPU is still called Adreno 650 and offers a slightly higher clock speed of 670 MHz.
The on board Hexagon 698 DSP now offers a KI performance of up to 15 TOPS (up from 7 TOPS in the 855) and still uses a combination of CPU, GPU, HVX and Tensor cores. The Spectra 480 ISP is also untouched. The integrated Computer Vision Engine (CV-ISP) now supports Dolby Vision, 8K videos and 200 megapixel photos.
The built-in memory controller supports LPDDR5 with up to 2,750 MHz and LPDDR4X with 2,133 MHz.
The SoC is manufactured in the modern and power efficient 7nm process.
Mediatek Helio G85
► remove from comparison
The Mediatek Helio G85 is a mainstream ARM SoC for smartphones (mainly Android based) that was introduced in 2020. It is manufactured in a 12 nm FinFET process and integrates 8 CPU cores. Two fast ARM Cortex-A75 cores with up to 2 GHz for performance tasks and six small ARM Cortex-A55 with up to 1.8 GHz for efficiency. All eight cores can be used together thanks to Heterogeneous Multi-Processing support. The integrated GPU is a ARM Mali-G52 MC2 (MP2) with two clusters at up to 1000 MHz (up from 950 MHz from the otherwise similar Helio G80). The SoC also integrates the HyperEngine that handles a dynamic management of CPU, GPU and memory.
The SoC integrates furthermore a LTE radio with Cat-7 (download) / Cat-13 (upload) support, Wifi 5 (ac), Bluetooth 5.0, LPDDR4x 1800 MHz and eMMC 5.1 storage.
Qualcomm Snapdragon 865
► remove from comparison
The Qualcomm Snapdragon 865 Mobile Platform is a high-end smartphone and tablet SoC that Qualcomm announced in December 2019. The SoC integrates a fast ‘Prime Core’ that clocks up to 2.84 GHz and three further fast ARM Cortex-A77 performance cores, which can reach up to 2.42 GHz. These are complemented by four power-saving ARM Cortex-A55 cores that clock up to a maximum of 1.8 GHz. The difference to the older Snapdragon 855 is the switch from Cortex-A76 to the faster Cortex-A77 architecture. The clock speeds stay the same.
Therefore, the Snapdragon 865 takes the top spot in mobile processors for Android based systems. In some multi-core workloads, the SD865 can even perform on par with the Apple A13 SoC. Single thread, however is still a strong suit of the Apple SoCs.
Compared to the previous generations, the Snapdragon 865 does not integrate an LTE modem anymore, but has to be paired with the new X55 5G modem, that also supports LTE Cat 24/22. The Wi-Fi module however is still integrated and called FastConnect 6800 with support for Wi-Fi 6 (802.11ax) and 8x8 MU-MIMU and 60 GHz 802.11ay with up to 10 Gbps. Bluetooth 5.1 is also supported including aptX Adaptive.
The integrated GPU is now called Adreno 650 and should offer 20% more performance than the Adreno 640 in the Snapdragon 855.
The on board Hexagon 698 DSP now offers an improved KI performance of up to 15 TOPS (up from 7 TOPS in the 855) and still uses a combination of CPU, GPU, HVX and Tensor cores. The Spectra 480 ISP is now also significantly faster. The integrated Computer Vision Engine (CV-ISP) now supports Dolby Vision, 8K videos and 200 megapixel photos.
The built-in memory controller now supports LPDDR5 with up to 2,750 MHz and LPDDR4X with 2,133 MHz.
The Snapdragon 865 is manufactured at TSMC in the new improved 7nm process (N7P, DUV-based). The process offers a 7% higher performance or 10% less power consumption compared to the old N7 process.
