Black screen troubleshooting using integrated graphics?

Hello,

1. Does [5600g with AMD RX 6500XT 4 GB - Powercolor] have the problem mentioned in the reddit thread below?

2. Does [5700g with AMD RX 6500XT 4 GB - Powercolor] have the problem mentioned in the reddit thread below?

3. [5700G with AMD RX 6500XT 4 GB - Powercolor] vs [5600X with AMD RX 6500XT 4 GB - Powercolor], which one is better/faster?

4. [5700G without dedicated graphics card] vs [5600X with AMD RX 6500XT 4 GB - Powercolor], which one is better/faster?

5. [5600G with AMD RX 6500XT 4 GB - Powercolor] vs [5600X with AMD RX 6500XT 4 GB - Powercolor], which one is better/faster?

6. Initially I was thinking about [5600X with AMD RX 6500XT 4 GB - Powercolor] but after some research I was thinking the CPU should have integrated graphics so I decided [5600G with AMD RX 6500XT 4 GB - Powercolor] or [5700G with AMD RX 6500XT 4 GB - Powercolor] because during black monitor screen problem it is much easier to troubleshoot if the dedicated graphics card is faulty since I can try removing the dedicated graphics card and use only the integrated graphics on motherboard to see if image will appear on screen again. Even if dedicated graphics card is faulty, I can continue work immediately because the integrated graphics is very unlikely to become faulty. Any comments on my thinking?

I saw this in reddit:
"The 6500xt with the 12400 or 12100 from intel 12th gen would likely be a good pairing. The problem with running the 6500xt with the 3600 is that the 3600 lacks an IGPU, which would fix a lot of the problems that exist with the 6500xt- namely the lack of streaming encoders/decoders, and lack of display outputs.
The 6500xt would have far better performance then the 5600g." Source Blocked

Additional question
7. Does 5700G have the problem mentioned in the reddit thread below? It seems like CPU with integrated graphics will make dedicated graphics card slower. My motherboard is Asus B550M-A Prime Wi-Fi II & Bluetooth (DDR4)

I saw this in reddit
"Yes but I would recommend you to sell your 5600G for a 3600 or 5600X if you get the 6500XT. The card will be gimped at PCIE 3.0 x4 when it runs out of VRAM which is pretty common in today’s games with 4GB even in low-medium settings.
The 5500XT 4GB already lost 10-20% of performance when using a PCIE 3.0 x8. I would expect the 6500XT to lose even more using a PCIE 3.0 x4.
5600G only supports PCIE 3.0 so that is the issue. Also you must have a PCIE 4.0 supported motherboard (500 series and some high end 400 series)
If not, don’t bother getting this card as it might end up performing like a RX 570 or slower unless you make sure the games you play doesn’t exceed the VRAM buffer. This card was pretty much made for PCIE 4.0 systems with just 4 lanes." Source https://www.reddit.com/r/pcmasterrace/comments/rrieu2/would_a_6500xt_be_a_good_upgrade_from_a_5600g/?rdt=61297
