Hornestly. All of the low end gpu's available, specially if you are looking for a low power cards that can be powered by the pcie bus alone, Is a joke.
I mean what are there to choose?
RX 6400 is just a laptop gpu in desktop format, only running x4 on pcie lane.
GTX 1650, meh pretty old by now.
GTX 1630 was such a joke and just gave me bad taste.
Then there are the others like gt 710 still sold, gt 1030 and so on. More like a display adapter, calling them a grafich card is a joke.
And none of these cards have more than 4 gb vram at best and it as been like that since gtx 1050/ti launched.
So yes I apselutely want both amd and nvidia to make better low-end gpu's. What they offer now is either old tech or just plain boring.
I was in the same problem only a few months ago wanted to replace my GTX 1650 with gddr5 memory. But the truth is that there was no alternative to a good replacement for a gpu only powered by the bus itself. Gtx 1650 was simply even 2-3 years after launching still one if the fastest card available. This should tell how bad and how little bofh nvidia and amd care about the low end segment of gpu's
I searched Google empty for info on a replacement card. There where nothing worth to upgrade to. First when I search in nvidia professional lineup, I actually found what I was looking for. Simply a rtx 3050 look a like card with more than 4 gb vram that could be powered by the bus alone.
The solution was rtx a2000 and that's why I have a rtx a2000 today. There where simply no other card that offered everything I wanted from a little card.
