Is there a dedicated PCIe lanes in CPU for GPU after the advertised PCIe lanes on CPU?

[NJohn5]

I have been hearing this myth for long time. Some people claims that Intel CPU have dedicated PCIe Lanes for GPU excluding the advertised PCIe Lanes. For eg, A i7-7800X cpu have 28 lanes. But it says there is 16x dedicated lane for GPU excluding this 28Lanes. Which means, CPU have 28+16 lanes in total. But most people believe that GPU use the PCIe lanes advertised by Intel on the CPU spec. I want to know if there is any truth in this mythical PCIe lane for GPU. Thank you.
