Snapdragon 855 vs Snapdragon 865
I’m sure many of you are wondering why Microsoft isn’t using the latest Snapdragon processor from Qualcomm inside the Surface Duo, and the reason seems to be rooted in the fact that Qualcomm requires all smartphone makers to include a separate 5G chip with the Snapdragon 865. Surface Duo’s internal design was finalized way before that requirement was known about, and therefore doesn’t have room for the additional 5G chip that’s required when using the Snapdragon 865.
If Microsoft were to use the Snapdragon 865 inside the Surface Duo, it would have to significantly redesign the hardware inside and out to accommodate the required chip, throwing out most of the work that Microsoft has put into Surface Duo V1. Critics have touted the Snapdragon 865 as a step backwards in smartphone design for this very reason, as it also uses more battery and increases the price of smartphones. This should change when Qualcomm builds a 5G modem into the System on a Chip (SoC.)
Either way, the use of last year’s flagship processor shouldn’t degrade the experience in any way. The Snapdragon 855 is still an excellent chip with great performance and efficiency.
It’s important to remember that Surface Duo isn’t about raw specs; it’s about form factor. Most of the innovation coming out of Surface Duo is in the 360-degree hinge and dual-display setup. That said, for $1399, there’s a lot of old tech in here that many people won’t be able to justify.
