AM5 or Alder Lake is costly due to their shift in chipsets
After 6months or 1 year everything becomes not so cheap like in sales in US but like normal in India as well.
Newer chipset along with processor change,
Newer memory interface,
Newer GPU bandwidth and PSU cables change
Newer PSU standard might be released to accommodate the newer GPUs by AMD, Nvidia and Intel.
All these above needs to settle down after they become only mainstream
Like A620 like mobos or B650 mobos with both ATX and mATX form factors.
