Wait if there is a clock regression and going back to 8core with rocket is that Intel going backwards now?

what? oki, this is what I call fanboyism xd

By the time we see an 11900k on shelves, Zen 3 will likely be out. Comparing the predicted performance of Rocket Lake to Zen 2 doesn't seem appropriate. We're not comparing the 10900k to the Ryzen 1800x...

The point is will all Z490 boards support 4.0 or going to be a blanker approach "only Z590 will support 4.0 to avoid confusion".
Not something we haven't seen from Intel over the last 3 years numerous times but I would like to see all those Z490 defenders when this happens, especially knowingly upgraded to a platform that is dead next year with the 1700 socket.

I'm really to curious to understand how the extra 4x pci express lanes will work. I m asking this myself since day 1 of this news.
Current boards have only 16 lanes connected to the socket, for the gpu. the new cpu will have 16 + 4.
Any clue?

I have said this before if you are upgrading and going Intel and want PCI e 4 wait for the new chipset because current Z490 board designs which claim support are going to have problems and if you can not wait forget PCI e 4 and go low cost with intention of upgrading when PCI e 4 and DDR5 support become available. with the new die shrink Intel CPU`s by which time you will have given up and gone AMD.

These lanes are for the M.2 NVMe slot.

Strange - I thought Intel was skipping 4.0?
kakiharaFRS
this might finally make Intel viable and better as a "gaming" plateform because enough lanes for at least one system nvme is mandatory in 2020 (if you ask me) and reducing your uber 1300$ videocard to 8x (or costing you 2 sata ports) wasn't a good look for the "best gaming plateform"
considering 4.0 already demands higher quality more expensive motherboards I was hardly seeing Intel do more than 4.0 irl

I think it will be out instead of likely. I mean AMD said Zen will be released later this year and since intel just released Comet Lake i don't see them releasing new CPUs and chipset before the very end of this year at best and honestly i don't expect them before next year. Would not be surprised if Zen 3 is 2-3 months old when Rocket Lake is released. And yeah Zen 2 is like 1 year old so comparing it to a CPU that will likely be released in 5+ months is kind of silly 😉

I do not see whats different of RL layout over Zen 2. Same 20 4.0 lanes from CPU to GPU/NVME plus same bandwidth to Southbridge. (Intel 8x 3.0, AMD 4x 4.0).
So 500 chipset, I guess Z490 dead months after it got released......

You could also say the same about the Z590 chipset or what ever they decide to call it. It will be just a one hit wonder until the next new socket comes out.
asturur
Yes, that was the only clear thing. On today z490 those m2 slots are connected to the chipset itself, because today in the current lga 1200 cpu those lanes do not exist. Will a today z490 motherobard able to use them? i suppose no.

Zen2 Ryzen (socket AM4) also includes USB 3.1 Gen 2 (10 Gbps) and reconfigurable PCIe/SATA lanes, similarily to the x570 chipset (which is based on the I/O die in Zen 2 EPYC/Threadripper that comes with a total of 64 PCIe lanes).
400-series motherboards are not designed to use these extra 4 lanes. The whole Comet Lake S / LGA 1200 platform just makes no sense for the DIY enthusiast.
