Featuring a top of the line 18+2+2 VRM using 105 A power stages, DDR5 support, PCIe Gen5 support, dual M.2 Gen5 sockets and loads of high-speed USB ports, the BIOSTAR X670E VALKYRIE is ready for you! Come along as we dig into this motherboard review to uncover all the secrets the new AM5 platform has to offer.
Thanks for the review. Would you be able to take another photo of the area below, to identify the chip above PI3HDX12?
PI3HDX12 seems to be a redriver for HDMI 2.1 output from iGPU. But, I am not sure. Do you know?
The chip above it might be a level shifter/mux for HDMI FRL signal, but it's not visible here.
I am asking this for two reasons.
1. AMD claims that iGPU on 7000 CPUs supports DP 2.0 (at 40 Gbps?) and HDMI FRL (allegedly up to 48 Gbps)
2. It is not clear whether support for these video outputs is baked into CPU or additional chips are needed to provide those signals?
It would be very useful to identify those chips and find out what they do. I have looked into every X670(E) and B650(E) currently on the market. No vendor has enabled DP 2.0 from iGPU so far. As for HDMI 2.1 FRL, only Asrock and MSI's MPG line claim to support FRL output at 32 Gbps (8 Gbps per lane x4).
As this is the first ever generation of motherboards to have modernised HDMI output from 2.0b (18 Gbps) to real 2.1 speeds (32 Gbps, like PS5), it would be good to know how it is done.
