Motherboard manufacturers Release AM4 BIOS With Raven Ridge APU Support
While intended for mobile, it seems that the AMD Raven Ridge APUs will reach the desktop platform as well, as motherboard manufacturers are rolling out BIOS updates supporting Raven Ridge.
That means the APuwould work and fit in the existing AM4 socket. Raven Ridge is based on four Zen cores and 10 GPU shader clusters holding 64 streaming processors each. Matched up, that's close to a comparable quad-core Ryzen 5 processor but now with, let's say a Radeon RX 550 video card. The news reaches the web through planet3dnow who noticed the BIOS updates.
ASUS, for example, is currently distributing version 3203 ( direct link to the zip file ) for the ASUS Prime B350M-A, which brings with it "AGESA! V9 RavenPI-FP5-AM4 1.0.7.1" and support for Bristol Ridge, Summit Ridge and Raven Ridge. In addition, to support for the CPU part (ie AGESA), the respective video BIOS is included (BRISTOL AM4 Generic VBIOS and Raven Generic VBIOS). The fact that BIOS updates are already being distributed suggests that the Raven Ridge family's desktop representatives will soon be making a big start.
Due to the demand here is the list of motherboards for which a corresponding BIOS update is available:
- EX-A320M-GAMING is still missing
- PRIME X370-PRO
- PRIME X370-A
- PRIME B350-PLUS
- PRIME B350M-A
- PRIME B350M-E
- PRIME B350M-K
- PRIME A320M-A
- PRIME A320M-C is still missing
- PRIME A320M-C R2.0 is still missing
- PRIME A320M-E
- PRIME A320M-K
- ROG CROSSHAIR VI HERO is still missing
- ROG CROSSHAIR VI EXTREME is still missing
- ROG STRIX X370-F GAMING
- ROG STRIX X370-I GAMING
- ROG STRIX B350-F GAMING
- ROG STRIX B350-I GAMING
So far we have not been able to find updates for motherboards from other manufacturers with Raven Ridge support.

There's no information about that - at least I haven't seen any - but I doubt it.

There is supposedly the ability to delegate in DirectX 12, but haven't heard anything since it was initially reported.

Nothing is automatically done by magic, it has to done by the application developer. Here is a sample demo: https://github.com/Microsoft/DirectX-Graphics-Samples/tree/master/Samples/Desktop/D3D12HeterogeneousMultiadapter
The same logic, though for different tasks, is used in AotS when you run the game with both AMD and NVIDIA GPUs on the same system.

In the past they could be paired up with something similar, in this case it would be a RX460, but that depends on if they can allow Vega and Polaris architectures to work together which i doubt. Maybe they can reduce power draw in that when ideal or minor graphical work use the APU GPU while the external graphics card is idle to save power consumption

Will these APUs work in mGPU config with a discrete video card?
