and ddr4 most importantly

not true
it will on asrock z790 and h770 so it will be for the rest too

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

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.

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
