Hot on the heels of yesterday's leak revealing that the Ryzen 5 8600G Socket AM5 desktop APU features a Radeon 760M iGPU with 8 CU, we're getting to know that the top of the line Ryzen 7 8700G comes with the maxed out Radeon 780M. The 8700G is a Socket AM5 APU based on the 4 nm "Hawk Point" or "Phoenix" silicon (unclear at this point).

The Ryzen 7 8700G features an 8-core/16-thread CPU based on the "Zen 4" microarchitecture, with a base frequency of 4.20 GHz, and a maximum boost frequency of 5.10 GHz. Each of the 8 CPU cores features a 1 MB L2 cache, and they share a 16 MB L3 cache. The Radeon 780M iGPU features 12 compute units (CU), amounting to 768 stream processors. The iGPU engine clock boosts up to 2.90 GHz. While all Ryzen 7000 desktop processors come with integrated graphics, AMD does not consider them to be APUs—processors with overpowered iGPUs that can be used for entry-level gaming besides high-resolution entertainment.
 
This looks like a very fine desktop APU.
