So with the rolling out of X299 details and them still using PCI-e 3.0 when do people expect to see PCI-e 4.0 to actual roll out as rumours originally put it in August or so this year.
Further to that, will we see DMI 4.0 link as that is a bottleneck even now with the storage we have via M.2 and U.2.
The X299 series with 44 PCI-e lanes rumoured would mean the ability for SLI at x16 as well as 3No. M.2 x4 all off the CPU lanes. This would then mean no DMI bottleneck but then we still have the 24 lanes from the Chipset and that is where the issue occurs. Let's assume we go with U.2 connectors via PCIe we could theoretically have 6 connected. Now each one in itself is capable of hitting the 4GB limited that DMI 3.0 has and thus RAID is not possible to offer benefits (at least in read).
The ability for DMI 4.0 would really need to offer 16GB of simultaneous data stream and that is just for storage devices we have now with PCI-e 3.0.
Further to that on-bard USB-C would be excellent and honestly I would really like to see a mobo that gets away for legacy support to put an enthusiast board on the market for the enthusiast chips.
So with that overall we are talking about;
M.2
U.2
PCI-e 4.0
DMI 4.0
With enough lanes to support RAID setups and multi-gpu's as needed.
Is there anything else significant people would like to see in newer mobo? Change in shape/size? How about general layout configurations? What about LAN chips and onboard sound.
Would a custom riser board via it's own PCI-e 4.0 circuitry improved sound compared to now with proper shielding etc?
What about power phases. A few years ago it was all the rage to have improved power circuitry with fancy ideas coming through. Now it's not mentioned for pretty much any of the new mobo releases.
Is thunderbolt needed? What does it offer compared to USB-C and would a split between the two be best in terms of current requirements.
