But why minecraft doesn't use graphics card for shaders? Since i have a amd card vulkan is performing better, so it must be issue with opengl.
I don't know, with Minecraft you have to have a balance between cpu and GPU (and RAM speed), and with older CPU do not matter which kind of GPU you have, you are going to have FPS issues nonetheless.
But 150 FPS with shaders are hard to believe - even good PCs running shaders with 60 - 90 FPS
Confirmed. My notebook has a 7th generation i7 and an high-end discrete nVidia video card and even on 1280x720 it doesn't go beyond 75 fps (it reaches 80 but immediately thermal throttling kicks-in even with an external cooling base). Also it seems that in fullHD it reaches nicely 60fps but it's very hot.
With no shaders I can exceed 120fps but then I go for a 60 fixed for thermal reasons.
Note, the results are comparable under windows and under linux, but on windows fps go up and down, I think there are windows processes that interfere, I do not know if there's some kind of “gaming mode” that has to be selected, I'm no windows expert.
Can anyone help with this problem, title says it all.
Ingame press F3 - is the RX 560 shown on top right corner?
Yes. I am currently installing new drivers maybe they will help.

You have a very old (~12 years) CPU and your system is likely running with slow DD3 memory. It can be a huge performance hog.
Try to see if FPS go up playing with a lower resolution (e.g. 720p resolution, or 1280x720), while still playing in fullscreen.
You can test older minecraft versions and different shaders
I think the gpu is to weak for some shaders
Fps doesn't change
So it's probably 100% a CPU issue. Try lighter shaders.

My friend has same amount of ram, i5 3470, same graphics card just from sapphire.
It is not an issue with RAM/VRAM - it has hardly any significant influence on your FPS
CPU and GPU are important
The RX 560 cant get more with Shaders
There are some benchmark tests with that GPU:
Via Optifine check the settings and set them to low
Search for some Light-Shaders and also check the settings
So it will be possible to get 30 FPS
Then how does my friend run same shaders at 150 fps. He has Sapphire RX 560, i5 3470 and 8gb ram. I know he has better processor.
Minecraft is a running java application - so a better processor will be increase the performance

Without Shaders and a low render distance 150 FPS should be easily possible
