The primary difference between the Snapdragon 855 Plus and the Snapdragon 855 is in the CPU and GPU. Like the Snapdragon 855, the Snapdragon 855 also has a tri-cluster CPU arrangement, with one Kryo 485 Prime core, three mid-cores and four efficiency cores. Only, the single Kryo 485 Prime core is clocked at 2.96GHz instead of 2.84GHz. The higher clock-speed essentially brings the flagship chipset closer to the speeds promised by ARM for the Cortex-A76, on which the Kryo 485 is based. However, considering the architecture is the same in both the chipsets, we’re not sure whether there will thermal bottlenecks when running at peak clock speeds. Next, the Adreno 640 GPU on the Snapdragon 855 Plus is 15 percent faster than the one on the regular Snapdragon 855.

Apart from this, the rest of the components in the SoC are the same. The Snapdragon 855 brings a dedicated Computer-Vision accelerator in the ISP along with the fastest 4G modem for mobile, as well as support for a 5G chip. There’s also dedicated Tensor and Vector accelerators in the DSP which aids in customised AI tasks and supports the most cutting edge hardware available for mobile at present.

It’s very unlike Qualcomm to release yet another flagship SoC in the same year. However, it can be argued that the Snapdragon 855+ is just an enhanced version of the 855 and not a replacement or an upgrade. Qualcomm saw an opportunity in the budding mobile gaming market and tried to make the best of it.
