Snapdragon 875 specs are allegedly leaked: 5nm, new GPU, VPU and more

Qualcomm's Snapdragon 865 may be the ultimate techy-household name in 2020. However, it may quickly become outshone by its successor, the 875. 91Mobiles has gotten the rumor-mill on this putative 2021 flagship processor started. It claims to have a source with access to this upcoming chipset's specs.

This leak asserts that the 875 will indeed be Qualcomm's first 5nm mobile processor. This may confer advantages in terms of speed, footprint and efficiency on the 865's possible replacement. However, this new report does not discuss this point in any detail, offering an insight on the chipset's make-up instead.

This may involve a new "Kryo 685" CPU based on "v8" (A8x?) ARM Cortex cores. It will apparently be joined by an Adreno 660 GPU, as well as an Adreno 665 video processing unit (VPU) and an Adreno 1095 display processing unit (DPU).

These slightly obvious upgrades over current flagship chip components are now touted to also share their platform with a Qualcomm SPU250 secure processing unit, as well as a new Spectra 580 image-signal processor (ISP).

The 875 may also feature Snapdragon Sensors Core Technology, a "Compute" Hexagon digital signal processor (DSP) with Hexagon Vector eXtensions and a Hexagon Tensor Accelerator. For other I/O, there may be a low-power audio subsystem with Aqstic's WCD9380 and WCD9385 audio codec

The SoC is also now said to support up to quad-channel high-speed LPDDR5 SDRAM. 91Mobile's source also mentioned both mmWave and sub-6GHz 5G support in conjunction with the upcoming 875, but failed to specify whether this needs an external modem (again) or is directly on the chipset this time.

Finally, this upcoming top-of-the-line silicon may originally have been destined for a December 2020 launch; however, current events may unavoidably push this back into next year.
