    Only if you have z690 ddr4 board. I dont think Z790 will support it so only ddr5.

    Doesn't really seem like a worthy upgrade for anybody already using Alder Lake-S.

    but for someone who has a great b-die bin and is coming from older cpus like ryzen 3000/8-9-10th gen

    Is it just me or are CPU''s kind of boring right now? I'm looking forward to the new GPU's but CPU's I just can't get myself hyped up.

    Not only you, it is boring. If you have ryzen3000 or intel 10gen it kinda isnt worth upgrading. Im waiting for a mainstream ddr5 to build a new system.

    translating it for those who haven't seen my rants on my current Z690 and because no professionals talk about it, just like they don't talk about the ddr5 not working properly with 4 sticks, which judging by the comments on youtube will piss off a lot of people working with their computers if AMD hasn't found a fix for that

    The 16 PCIe Gen5 lanes may be divided in half (lies divided by 4 or 8 unless you only have 5.0 components) providing a PCIe Gen5 x8 (lies it's actually x8 4.0 or 3.0 depending on your gpu ex: your 4.0 rtx3090 will run at 13Gb/s aka x8 4.0 or the equivalent of x16 3.0 >< very high tech...NOT...the x8 is a fixated number then your device decides which pcie speed you get) connection for the GPU and two PCIe Gen5 x4 (lies again same thing you'll get x4 4.0 or 3.0 depending on your nvme) connections for the SSDs

    when everything was 3.0 it wasn't a real problem, 4.0 wasn't really either as we at least had 4.0 gpus and nvmes but the problem is that everytime PCIE goes faster the bandwith loss because the multiplier is fixed increases drastically

    another way to explain it currently with our max 4.0 hardware
    12900k linked to 1 gpu pcie slot + 1 m.2 slots
    - no M.2 + one GPU = x16 not 5.0 (52gb/s) but x16 4.0 (26gb/s) 26Gb/s lost into the void
    - one M.2 + one GPU = x8 4.0 (13Gb/s) x4 4.0 (6.5Gb/s) 32.5Gb/s lost into the void

    I don't know if I'm clear but currently an X570 with 4.0 gpu and 4.0 m.2 you lose zero bandwith it's shared, but since we don't have 5.0 parts and most people won't change their gpus and nvmes just for 5.0 is not an upgrade but a downgrade because all the added bandwith is unuseable, you're still paying for it tough

    It is boring. We know everything will be super expensive (specially DDR5) and new platform always spell bugs and instability.
    On the other hand, we have AMD coming with MCM GPUs like Ryzen did and Nvidia still betting on monolithic design: we want to know who's gonna win this time.

    2x16 6000mhz hynix cost the same as 2x16 3200mhz c14 b-die now :) (Kingston Fury Beast 6000)

    So is ddr5 very expensive?
    2x8GB ddr5 hynix is pretty much the same price as 2x8GB b-die.
    The TOP bin 2x16 ddr4 4000c14 has the same price as top bin ddr5 2x16. 6600c32/34

    4 sticks works fine with alderslake when you know what you're doing and what the limitations are. :rolleyes:

    everything else you said is on point though, i don't even see where this chip has more lanes.

    the DMI?

    Alder already had 16x 5.0 lanes that can operate at 4.0 and 3.0, which dropped down to 8x when you used a nvme on m.2_1
    • The only thing to take aware here is that mainboards DID NOT have the m2.2 port on the other half of the bifurbated config.
    Alder already had 4x 4.0 lanes that didn't take away from the 16 5.0 lanes
    • which just about every motherboard had connected to m.2_2
