[SOLVED] Do the pcie express lanes of the cpu need to match the ones of the mobo?

Hello guys today I spoke with a computer store employee and he told me the number of pcie lanes will have an impact on cpu performance and to get a b460 board instead of a h410 for my i5 10400 is this true?
If anything I thought it would affect gpu performance.

Some useful links:

https://ark.intel.com/content/www/us/en/ark/products/201842/intel-h410-chipset.html H410 Chipset

He probably saw that the H410 says 6 and the cpu 16 but why would intel release such a board if it just hampered performance like that.
Also I dont get how it could have 6 and run the gpu on 16x im guessing its completely unrelated and im just making a fool of myself.
Thanks in advance

You would be fine with 8 lanes for your GPU and the B460 has 16 available, so NVMe and whatnot would be pretty well supported. The H410 would not be optimal for a high performance use situation with far fewer PCIe lanes available.

The H410 is limited to 4 SATA 3 ports and only 2 memory slots, so it really is for a lesser use situation.

Im sorry for replying this late but I wanted to ask : is my gpu going to run at 4x because of only 6 pcie lanes?
