The Samsung S10 is now the world’s most advanced smartphone powered by Qualcomm’s 855 – at least until Huawei challenges with its new Kirin 990 in the coming Mate 30 series.
This is an article about smartphone technology and how the evolution under the bonnet affects us all. Invariably today’s flagship processor, in this case, the new Qualcomm Snapdragon 855 features will flow down to the Snapdragon 7XX, 6XX, 4XX and 2XX series.
Note that the Qualcomm Snapdragon 855 is for use in certain international markets. Samsung also uses its Exynos 9820 that has similar performance specifications to the Snapdragon 855 (in all but name!) and powers the S10 series in many markets.

Why the two chips?
Samsung needs to control its silicon, just as Huawei has its Kirin and Apple its A-series chipsets. If you want to do something different you need to make sure that the silicon can support it.

To my trained eye, there are a few minor differences, but none that really matter – in real life the new 7nm Snapdragon 855 is marginally ahead of the 8nm Exynos 9820 in performance.
Qualcomm Snapdragon 855 integrates even more into the chip
One of biggest advancements is the tighter integration of formerly separate components into a single System on a Chip or SoC. This means smaller chips (Qualcomm 855 is now a very thin 7nm) that use less power and do not suffer the loss of speeds by using an external bus to connect them.
The 855 has eight-cores that run up to 2.84GHz each. This scales up or down as needed and gives 45% more performance over the 845.
It also supports USB-C 3.1, Wi-Fi 6 (AX), Bluetooth 5.0 (2Mbps), NFC and almost every version of GPS, QZSS, GLONASS, SBAS, Beidou, Galileo, Dual frequency GNSS.
Wi-Fi 6 gives MU-MIMO and HT160 (aggregation) with supporting routers for up to 10Gbps speeds.
20% faster graphics than the previous generation while continuing to lead the mobile industry in performance per watt. It has full AR and VR functionality.
It supports 4K, HDR10+ (video capture and screen), 10-bit (1 billion colours) and Rec 2020 colour gamut. That is the best you can get. It supports OpenCL 2.0 FP, OpenGL ES 3.2, Vulkan 1.1, and DX12 standards.
X55 5G modem
The 855 incorporates its X24 4G LTE modem which means Dual Sim Voice over LTE (VoLTE), Ultra HD Voice; Cat 20 2Gbps download/Cat 13 316Mbps upload, 7x20MHz carrier band aggregation and more. It is the fastest 4G can go subject to the Telco’s network implementation. This is for the S10 series.
The Galaxy S10 5G version adds the X55 modem for multi-gigabit speeds using the sub-6 GHz and mmWave frequency bands. It also supports 5G non-standalone (NSA) and standalone (SA) modes, and 5G/4G spectrum sharing.
