Qualcomm Snapdragon 855+ / 855 Plus vs Qualcomm Snapdragon 865
Qualcomm Snapdragon 855+ / 855 Plus
► remove from comparisonThe Qualcomm Snapdragon 855 Plus (855+) Mobile Platform is a high-end smartphone and tablet SoC that Qualcomm announced in 2019. Compared to the normal Snapdragon 855, the 855 Plus offers higher clock speeds of the GPU and CPU. The SoC integrates a fast ‘Prime Core’ that clocks up to 2.96 GHz (up from 2.84 GHz in the 855) and three further fast ARM Cortex-A76 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 SoC also integrates the new X24 LTE modem that Qualcomm promises will deliver up to 2 Gbit/s maximum download speed over LTE Cat.20 and up to 316 Mbit/s upload speeds. The Snapdragon 855 can be configured with the company’s new X50 5G modem too.
Qualcomm has also improved the integrated Wi-Fi modem, which is Wi-Fi 6-ready, has 8x8 Sounding and supports up to 802.11 ay Wi-Fi. The Wi-Fi modem can utilise the 60 GHz mmWave band for up to 10 Gbit/s internet speeds.
The Hexagon 690 DSP has undergone the most revisions of that which Qualcomm has integrated into the Snapdragon 855. The new DSP incorporates a neural processing unit (NPU) with dedicated Tensor-cores that can execute up to 7 trillion operations per second in conjunction with the CPU and GPU. In short, the Snapdragon 855 should be three times faster than the Snapdragon 845 and two times faster than the Kirin 980 SoC.
The Snapdragon 855 also has a Spectra 380 ISP onboard, which is the world’s first chip to incorporate a Computer Vision Engine (CV-ISP) that can perform depth calculations in videos at up to 60 FPS. The Snapdragon 855 should deliver real-time portrait modes or be able to detect objects with relatively low power consumption.
The built-in memory controller supports up to 16 GB LPDDR4x RAM (4 x 16-bit). As the SD855, the 855+ integrates an Adreno 640 graphics card that is now higher clocked and should offer a 15% higher performance.
Qualcomm will manufacturer the Snapdragon 855+ at the Taiwan Semiconductor Manufacturing Company (TSMC) using a 7 nm FinFET process.

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.
