can someone give me rundown/clarification about PCI lanes in regards to ports usage, motherboard slots and CPU ability
specifically, when i'm looking at the regular intel cpu, like lga1151 socket, says it has 16pcie lanes
but
a motherboard (still) comes with x1 slots -which seems confusing to me on "gaming oriented" mobos
wouldn't that just take up(/halve) your x16 gpu slot to x8? if used the x1 slots for "stuff" at same time?
or do those specific x1 slots not share lanes with the x16-8-4 "gpu slots"?
(as in could plop gpu in run at x16 or sli at 8x8 -and still pop in a couple of x1 pcie cards for other things "no problem" with no loss?)
and also m.2 "stick ssd" slots, if each takes 4 lanes, are they somehow separate lanes from the "regular" pcie/"gpu side lanes" and (intel specs just not mentioning them)?, or are motherboards coming with m.2 slots that actually reduce gpu bandwidth, making it silly to use 1 or even 2 m2 ssd slots as then it would also just cut your gpu down to x8?
basically i get confused when intel says cpu only has 16pcie lanes, but "there is all this stuff to be used"on xMotherboard; making me think in order to actually be able to use that stuff "fully"/proper one "has" to jump to a diff socked ex. lga2066 to get like 44 lanes or something???
cheers
