Compared with the previous Qualcomm Xiaolong 835 processor, the latest on-line Snapdragon 8cx has improved significantly in two aspects. The first is support for external displays. The Snapdragon 835 laptop can be connected to a 4K display, while the new chipset can support the connection of two 4K HDR panels. Technical features support the latest DX12 API, integrated efficient encoder, H.265/VP9 decoder, support for second generation HDRvideoPlay, you can output two-way 4K, that is, you can connect two 4K monitors.
In terms of performance, Qualcomm claims that the Snapdragon 8cx 7W thermal design power consumption can match the AMD/Intel 15W ultra-low power processor. If the latter is also limited to 7W, the performance can be doubled and the power consumption is much lower.
Like the Snapdragon 855, it also integrates the Snapdragon X24 4G baseband with a maximum download speed of 2 Gbps, supporting seven-carrier aggregation, 4x4 MIMO, and LAA authorized access.
Secondly, there is a clear improvement in graphics processing. The Adreno 680 on the Qualcomm Snapdragon 8cx can support hardware acceleration of up to 120fps 4K HDR video. In addition, at the press conference, Qualcomm also said that Firefox will natively support the ARM chipset, rather than emulating the x86 version. This naturally increases performance and power consumption significantly.
Technical features are as rich as PC processors, and even more, support QC4.0+ fast charging, Aqstic/AptixHD audio, Amazon Alexa/MicrosoftCortana voice assistant, USB Type-C interface, eight-channel LPDDR4X memory, NVMe SSD solid state drive, UFS 3.0 flash, PCI-E 3.0 system bus, dual 4K output.
