Maybe its a TDP choice ?
They could do a WS board, but just 4 extra PCIe lanes is weak, and X570 are going to be expensive anyway.
An x8 link to the chipset ? (get rid of any bottlenecks, perceived or otherwise).
DmitryKo
There would be little benefit from the extra 8 PCIe lanes in the PCH, as all these 24 lanes would map to the same 4-lane CPU uplink.
Now if they could reconfigure the CPU NVMe x4 link to double as the downlink lanes to the chipset...

Can they make 8 Dimms memory board? or maybe 4ch 8 Dimms board?
Since now they are at X299 league with 3900X/3950X and it's need more memory dimms slots or quad Chanel memory.
*TR X599 will be another league, no cannibalization.

I see I'm still future proof here with my dual haswell system, got 80 pcie 3.0 lanes, both gpus get x16, many expansion cards, 10x sata 6gbps + 4x sata marvell card, and an quad nvme m.2 card with full bandwidth, and have yet free lanes to spare. such are the spoils of workstation boards. Next on my list is not upgrades, but rather get an identical motherboard to keep for any case... As the cpus are unlikely to die anytime soon.

Yes for a workstation you are probably enough future proof.
For gaming you are probably in the 60fps range for as long as you want.
I recently upgrade from a i7 990x ( first gen ) to a ryzen 2700x and i was like 30% faster after 10 years.

freely reconfigurable as SATA or PCIe on each individual lane, similarily to the CPU on-die x4 link (tough the latter is somewhat less capable with only 2 SATA lanes).
I'd expect X590 would retain such capability for some of its additional x4 PCIe PHY blocks.

The X590 chipset is supposed to have additional PCIe lanes, so the primary M.2 slot would be routed through these lanes.
On the X570 half of the PCIe lanes are Evildead666

I have a dream, I have a dream, one x590 MB with just one 10Gb ethernet port an everything filled with S-ATA III ports... A dream about a NAS/p2p server O___O
This would a really nice solution...
Reddoguk
maybe the 590X supports DDR5 memory which isn't that far off according to some websites > Release date 2019 (estimate)

The FCH/PCH has nothing to do with the supported SDRAM type, you can also disable it in some MBs...
The memory controller is integrated in the CPU package..

I hope its true, i want one.
This PCIe lanes kills me, I always need more, i cant use more then 2 nvmes and i want at least 3[x4 each], i want capture card [x4], i want sound card card [x1] and i have my 5Gb Aquantila [x1] and i want RAID card [usually x8] and i want it all in one PC and to keep my GPU at x16

More PCIe lanes are probably for semi-pro users.
But... how does this chipset cooling look like? 😀
DmitryKo
WCCFtech news report implies "much higher" number of PCIe lanes, as well as much higher price.
That would only make sense if 16(32)-core Ryzen 9 3950X replaces lower-end Ryzen ThreadRipper processors - where Socket TR4 platform offers up to 60 PCIe lanes on the CPU (of which 48 lanes are dedicated to two x16 slots and two x8 slots, and 12 lanes to three M.2 NVMe x4 slots), as well as 4-lane chipset downlink.

CPU uplink lanes are typically excluded from the PCIe specs for both Intel and AMD platforms, even though they use PCIe protocol (like DMI 3.0 does) - only the external PCIe I/O lanes count towards the grand total.
That's how things were in eary 2000s, until AMD Opteron and Intel Core included the memory controller on the CPU die.
This would be no worse than current setup, but the chipset would have a wider uplink to better distribute the bandwidth to other peripherals.
[Quote]I think more likely they had planned x490 as a version with USB4, but it was not ready so they didn't launch it
Well, USB4 is essentially ThunderBolt 3 from 2017 - that is 4-lane USB Type-C active cable where the four differential lanes are shared between 2/4 lane PCIe, 1/2/4 lane DisplayPort, or 1 lane USB 3.
Release schedule for the USB4 specification is mid-2019, which means it's still based on Titan Ridge spec - i.e. PCIe 3.0, DisplayPort 1.4 and USB 3.1 (and not PCIe 4.0, DisplayPort 2.0, or 2-lane USB 3.2 Gen2x2).
So it's entirely doable, though IMHO it only makes sense to implement PCIe part of the ThunderBolt spec on the desktop platforms, since they offer multiple dedicated DisplayPort and USB3 ports.
