That's a pretty weak CPU for any sort of gaming -- especially if the system doesn't have a decent GPU card.

The game is processor-bound and the system really not suited to gaming at any level.

benchmark shows cpu bottlenecks gpu (-10%)

you can consider upgrade cpu to i7 or i5 (example i7-9700, i5-9400)

both cpu show no bottleneck w gpu (0%)

your i3-9100 is not good match with gpu.

i5-9400 is a good match

i7-9700 too if not too costly.

3070 can only support 9th or 8th gen cpu

@redxps630​ but i5 9400 is overpriced it is expensive than i3 12gen cpu . So can I play games with i3 9gen with GTX 1650, and will imthis give good performance but minor bottleneck?

Your original question is the answer to the same question you just posed.

Re: i5 9400 is overpriced it is expensive than i3 12gen cpu

you can get a i5-8600 less pricy affordable still better than i3-9100.

you cannot run i3-12th gen in 3070.  cpu socket, chipset, motherboard all non compatible

@redxps630​ I have seen many i3 9100f with GTX 1650 gaming benchmark videos games are running well and cpu is not heating and usage is also less then mine. What can be the reason ?

You'll need a CPU upgrade -- the one you have can't run RAM any faster than what you see, and the CPU controls the memory speed.
