Looks like one to me (under the spoiler tag).

 

As @Dash Lambda already pointed out, the 24 from the chipset on X299 will be effectively limited to x4 (same as what TR offers from their chipset).  Meaning the 10+ core chips will have an effective 48 PCIe lanes (68 actual) versus 64 on TR.

Yes there is an SLI bridge but not the awesome looking ROG SLI briddge with flashy LED

My bad, I just saw "SLI bridge" and didn't realize you meant a specific version of it.

Ya but TR like Ryzen even has very little running thru the chipset. Really believe why Ryzen is a smoother playing e penitence than my 6700k.

I use two GPUs (32 lanes), might want 4 NVME (16 lanes), and I have a 10Gbe NIC (8 lanes). 32 + 16 + 8 = 56 so cutting close even on TR so if I add anything else I could exceed 60 lanes dropping some slots down, if they don't already depending on how motherboard makers assign lanes to slots based on what is populated like they do now on every Intel board because they have to.

How much of a performance hit is there going from x16 to x8 in current compute heavy workloads? Is it the full 50% or are current cards unable to maximize bandwidth usage?

Well if we keep the discussion to gaming there is no difference between PCIe 3.0 x8 and x16 for GPU performance, most cards don't push the limits of PCIe 2.0 x16 and it's only recently that x8 would have a real meaningful impact on performance.

http://www.gamersnexus.net/guides/2488-pci-e-3-x8-vs-x16-performance-impact-on-gpus

 

The issues around PCIe lanes is more to do with design choices by motherboard manufacturers with how they switch lanes between slots or disable slots depending on installed configuration by the user. The issues I have with PCIe lanes doesn't really have much to do with GPUs, I'd rather have my GPUs drop to x8 than have a slot be disabled or drop to x4 just to keep one at x16.

 

I'm still on X79 (40 lanes) and I avoid the problems by using a server to externalize my storage, X99 would have the same problems for me or slightly worse since that platform actually has M.2 NVMe and U.2 NVMe.

 

Realistically on current high end Intel motherboards there are only 4 usable PCIe slots for someone using the platform as marketed, not a glorified gaming system. I'm the type of person who actually wants to be able to expand the system after purchase by adding more devices not replacing them. If I buy a 512GB NVMe because that's what I might need now and not a 2TB because I might need that later I still want to be able to get to the 2TB by using 4 NVMe drives in a storage pool. Also price over time goes down so I would have spent less than getting the single 2TB, I'm not doing it for performance it just makes better economic sense to get what you need not what you might need.

 

Intel really has lost their way with the enthusiast platform, the idea of a single storage device just wasn't a thing back in the day or even two maximum. People would be running 4-8 WD VelociRaptors either on onbaord SATA controllers or using hardware RAID cards and they would have multiple GPUs. Why is it that we have 6-12 SATA ports and usually only 2 NVMe ports? PCIe lanes.

 

Come on Asus two M.2 slots on a riser + 1 U.2? Everyone else has 3 M.2 and ASRock even has a U.2 port for a 4th NVMe device.

 

 

 

For HPC compute type stuff TL;DR yes bandwidth always matters, depends on workload/algorithms etc etc but more is always better. That's why NVLink exists.

 

Edit:

And no, 24 lanes from the X299 chipset isn't worth shit for NVMe devices or 10Gb NICs.

The 1920X is 12 cores and revealed to cost $800. There will be a 10 core chip. And yes, with all pcie lanes intact. 

Their will be no 10 core or 14 core parts.

Is there a reference or something for this?

AMD a while ago said they will keep CCX's balanced to insure consistency across products, software and software optimization. That was in reference to Ryzen but there is no reason for that to change for Threadripper.

 

So two dies and four CCX's means the lowest configuration that fits that requirement is actually 4 cores, why you would do a 4 core I don't know. Next is 8 cores then 12 then 16.

The recent leaks only Deen showing 12 and 16 core CPUs.

The alianware PC has stated to only be using 12 and 16 core thread rippers.

Ryzen and epyc only use balanced ccx configurations, Ryzen count divisible by 2 and epyc is divisible by 8.

AMD said all Ryzen CPUs will be balanced.

So this all points to Threadripper being divisible by 4, meaning it can only be 4, 8, 12, 16 cores.

 

Their pricing also leaves no room for a 14c part

That's awesoe looking, great package of accessories too. Sweet motherboard.

those 24 lanes from chipset come out of PLX that is fed with only 4 lanes from CPU....

PLX lanes is not the same as CPU lanes...

Threadripper will also have 4 lanes going to chipset for all we know MSI, Gigabyte and ASUS might as well spit out 24 lanes from chipset

that SLI bridge also has ROG branding on it... and why would you even want an SLI bridge? XDMA all the way !!!

Shit might even be a 8C Thread Ripper!

This board will most likely going to be replacement of my X79 motherboard.

For the same reason that an 8-core Epyc is rumored?

 

Because why not

It's confirmed.

The Octocore EPYC exists for memory bandwidth and PCIe capacity when core count is largely irrelevant.

Not on the chip though. Significant differences when going through chipset. There was a great ask GN episode that covered it:

Wait tf is that Dimm.2 thing? Is it PCIE X4 speeds or greater? 

It will go up to 8x bandwidth due to the presence of 2 M.2 ports on the DIMM.2

 

DIMM.2 from Asus is basically a special card that can host two M.2 devices and slots into a special port, much like you would slot in system memory.
