    Everybody: This end of the year should be awesome.
    Intel , AMD, NVIDIA all are gearing up to release all new silicons.
    Me: oh great. Hoping rtx4090 to perform great so that the price of 3080ti price would go down and i finally will be able to buy a 2nd hand 2080ti/6700xt with my budget.
    Lol

    I don't see any mention regarding Raptor Lake's PCIe 5.0 lanes..?

    Zen 4 offers 24 lanes enough for a GPU and 2 NVMe SSDs.

    Same as Alder Lake.

    I just don't need a CPU upgrade, but I very much like the "Netflix" of hardware, if you know what i mean.
    So let the fight begin. :D

    I imagine the forums be like:
    Intel beats AMD CPU's by 5%, AMD is crap for games...
    AMD beats Nvidia by 5%, AMD is crap for drivers...

    so possibly Z790 will be even worse than z690 ? did they learn nothing from z690 ?
    having more 4.0 lanes seems pretty bad to me because...
    every day I read comments of people that don't get how lanes and bandwith work including supposedly pros like Linus from LTT
    switching more lanes to 4.0 is a HUGE mistake it means more bandwith will be unusable, just like 5.0 is total garbage Z690 is a one pcie slot motherboard and you cannot use the main m.2 slot unless you want to throttle your gpu with x8 4.0 or 3.0

    every day..every one of them I read comments like
    "if you use the m.2_1 you get pcie gen5 x4 on m.2 and pcie gen5 x8 on pcie slot 1" WRONG
    "if you connect two pcie cards you get x8 and x8 pcie gen5" WRONG
    I don't blame people as it's manufacturers that purposefully keep writing "pcie gen5 x" in their descriptions when they know full well it's a lie, I got royally screwed over switching from X570 to Z690 as I actually use my pcie slots ><

    the truth is that you get x4 x8 of the pcie gen your hardware is..all the remaining bandwith is LOST
    meaning it's much smarter and useful to have more older gens lanes than fewer 5.0 or 4.0 lanes, that way it can be spread on multiple nvme slots, satas, a 10gb nic etc....
    4.0 is okayish but I'm pretty sure most don't have only 4.0 nvme, only half mine are
    hopefully more people have 4.0 gpus nowadays otherwise they'll get x8 3.0 roughly 6.5Gb/s >< on their videocard if they make the mistake of using the main M.2
    my cough according to manufacturers cough main pcie slot is supposed to be "pcie gen5 x16" +- 52Gb/s if I connect only a gpu no m.2 on a 1080ti I get x16 3.0 13Gb/s and so I would lose the equivalent of 48x 3.0 or 24x 4.0...awesome :/ (I have a 4.0 gpu but still you get the idea)
    if you connect an m.2 you halve that and so lose even more it's insane that no one addresses that

    Nobody cares except you. Last time someone cared about pci-e lanes was with the start of x299, and people used SLI. Even then, difference between x8 and x16 was about 5% worst case :p

    Noone is loosing any performance in real life.

    All Zen CPU's already have 24 lanes... the problem is it's split in 16x to the GPU/s 4x to Nvme to the CPU and 4x is to the chipset. As the last 4x will always be used for the chipset is why normally it's not listed as 24 lanes but 20 lanes. As Zen 4 is based on past Zen CPU's i am betting it's the same.

    So we can use only one PCIe 5.0 NVMe for Zen 4?

    Direct to CPU yes, but other PCIe 5.0 lanes can come from the chipset i.e X670 etc.
