Apparently the same A14X processor, with its integrated GPU (codenamed Tonga), will be used for the new 12in MacBook and iPad.
According to the report it's being produced using TSMC's 5nm process.
The iMac, when it gains a Silicon processor at some point in 2021, will feature a GPU know by the codename Lifuka. (Lifuka is an island that is part of the Kingdom of Tonga in Polynesia).

Integrated discrete GPU chips: Thanks to its high-performance GPU core driven by TSMC 5nm, the M1 is more powerful than the mid-range standalone GPU graphics cards. However, it is still insufficient for content creators. Therefore, Counterpoint believes Apple Silicon will integrate AP and GPU into a single chip by using advanced package"

The lack of support for external GPUs in Apple Silicon M1 Macs may only be temporary, as a connected eGPU is still detected, but doesn't do anything....
However, testing by Mac4Ever corroborated by AppleInsider's own trials, offers hope to eGPU owners. While eGPUs are not officially supported by the latest M1 MacBook Air, MacBook Pro, and Mac mini, macOS 11 still sees the enclosure, and the PCI-E card inside.
This discovery leads to the possibility that Apple may reintroduce eGPU support in the future. It would have to arrive as an update to macOS Big Sur, a new M-series chip launch, or possibly both.
