Can you provide your source for this information?

A1 records 8K in 4:2:0.

Interesting 8k editing of Sony A1 footage with Apple hardware.

&t=558s

That reference shows that NVidia 2000 series and 3000 series GPU's support h.265 (HEVC) 12 bit 4:4:4.

the lack of 4:2:2 support doesn't make sense, but then afaik it's not just nvidia, amd gpu doesn't support 4:2:2 either: https://www.pugetsystems.com/labs/articles/What-H-264-and-H-265-Hardware-Decoding-is-Supported-in-DaVinci-Resolve-Studio-2122/

so it comes down to the cpu.

as much as i hate intel, the latest intel cpus have a 4:2:2 support advantage over ryzen due to quick sync, that runs on a gpu that's internal to the intel cpu: https://www.pugetsystems.com/labs/articles/DaVinci-Resolve-Studio-12th-Gen-Intel-Core-vs-AMD-Ryzen-5000-Series-2247/

in theory you could have a monitor plugged into the nvidia gpu card, play games using it etc., while the hdmi port on the motherboard(aka internal intel gpu) is not connected, but the editing app would still be able to utilize quick sync decoding/encoding support... that should be researched before spending $$$

of course it's not like ryzen zen 3 is a dog for encoding, it was walking all over intel cpu in other encoding tasks at the end of 2020: https://www.anandtech.com/show/16214/amd-zen-3-ryzen-deep-dive-review-5950x-5900x-5800x-and-5700x-tested/15

Update 3:
I added 32GB RAM to my 16GB, all B-Die G.Skills.
Results? nothing changed .. timeline initial loading is faster by 2 seconds, but when editing memory usage is still below 16GB, playback from timeline still micro stutter.

On the other side, new memory is 3600MHz 16-19-19-39, but my old memory 17-18-18-38 was able to oc to 16-16-16-36, now they have to be used as 16-19-19-39, a minor downgrade in terms of speed

Update 4:
After I watched

?t=292" target="_blank" rel="nofollow">

?t=292
I got myself a little i5 12600K.

The UHD770 was able to decode the A1 8K via IGPU hardware, playback is very smooth to OK(4:2:2) in timeline with simple Slog3 color transformation

10 bit 4:2:0 uses about 18GB RAM and about 35% of IGPU's decoder, 10% CPU, 30% on RTX3080, 9-11GB VRAM used
10 bit 4:2:2 uses about 25GB RAM (capped by my 32GB RAM) and about 60% of IGPU's decoder, 40% CPU, same GPU usage, dropping a couple frames a second as green screen, not as smooth

I have to use Resolve 18+ version. Version 17 didn't work as expected (decoding went to Nvidia)

So all you need is Intel with IGPU (ideally 11700k, 12600k level, any SKU without F (i.e. 12700F))

Getting a 24GB VRAM GPU should be the way to go

well, unfortunately it looks like nvidia still doesn't have 10-bit 4:2:2 decoding capability with the new 40-series cards:

"NV_Tim
Community Manager
[Gerardo] GeForce RTX 40 Series use the same NVIDIA Decoder as RTX 30 Series - 5th generation NVDEC. There is no support for 10-bit 4:2:2 decode."

I shoot 8k/H265/4:2:2 on the A1. Between the resolution, data rate and H265 algo which is computationally intense, this will bring many systems to their knees

A few suggestions

1. use a 4K timeline vs. 8K. Unless you have an 8K display not sure why you would need to 8K for editing
2. use Resolve's 'Optimize Media' function to create proxies that are buttery smooth during editing, then delete when you are done
3. CPU, System Memory, GPU, VRAM and NVME drive speeds & capacity are all important. The relative importance of each depends on codec, what effects you apply (color vs. fusion etc).
4. For final exporting where native H264/5 encoding/decoding is the bottleneck, ironically Intel GPUs are currently the fastest and offer the widest compatibility across formats as of Fall 2022.

Hope this helps

ANOTHER UPDATE
Upgrading to 24GB vram 3090 made 8k 10 bit 4:2:2 editing very smooth.
Vram usage jumps up to 13GB with simple lut. 16 GB 4080 might be OK.
