[SOLVED] GTX 1650 GDDR6 @ PCIe 2.0

[1405]

I already know that the card will work on a PCIe 2.0 board. What I'm curious about is if the PCIe 2.0 bandwidth would be a bottleneck to the GTX 1650 GDDR6 card. Or not a concern with this low end card?

If not a concern, what about a RX-570?

either card will be fine.

Good. Thank you.
Where does PCIe 2.0 start to become a bottleneck? By that I mean what level of card begins to bottleneck at 2.0?

This is a 2080ti the 2.0 would equal 3.0 X8 speed.

Depending on your tolerance of how bad things are, an RTX 3080 only loses about 25% of its performance on PCIe 1.x x8, and about 10-15% on PCIe 1.x x16 (https://www.techpowerup.com/review/nvidia-geforce-rtx-3080-pci-express-scaling/27.html)

There's only three things a video card needs the PCIe bus for in-game (and not on loading screens)

• Receiving render commands from the CPU (higher FPS = more commands = higher bandwidth needed)
• Texture streaming
• VRAM swapping

That is the same site I had my information from the 2080ti looks like the first card to loose some performance but only 3%.
Funny how I remembered that for a couple years.

I consider <5% not significant enough. But even then, I don't consider performance loss to be practical until 15% or so.

I was just answering his question.
