If you only play games, don't own any other PCIe cards and don't get anything faster than a 1080 (not the 1080 ti) and never intend on upgrading your video card, then 16x lanes is fine. The 1080 ti does saturate 8x pcie - several videos on youtube and some other websites showing it. Not a tremendous difference but about 10% improvement using a 16x over an 8x slot depending on the game. If the 1080 ti already goes beyond 8x bandwidth then you can be sure the 2080 will need more. I also have an 8x nic and an 8x raid controller so I could use a lot more than 16x to share between them. I believe the threadripper has 64 pcie lanes however it doesn't perform as well for gaming as my old 6700k intel.

Please provide proof of 10% I’ve only seen ~3-5% depending on game and resolution. The funny thing is it doesn’t matter what card you use as you can reproduce this with a 1070 as well which means that the 1080ti is not saturating all lanes in X8. https://www.pugetsystems.com/pic_disp.php?id=40777&width=800&height=800

AMD is only 16 lanes for graphic with 4 dedicated for ONE M.2 and 4 for I/O that is 24 total. Intel has 20 total 16 for graphics 4 for their DCM3.0 (I think that’s what it’s called).

You are forgetting SATA ports and USB that is also directly connected to CPU.Each Ryzen die has 32PCIE lanes,so Ryzen 1die=32,threadripper 2die's=64, epyc 4dies=128.What is confusing you and why i said that i liked that AMD didn't lock 8lanes is the fact that AMD has taken 8lanes from Ryzen 3,5,7 Cpu's and assign them to sata and usb ports fixed ,so mobo manufactures can't assign that 8lanes to anything else they are locked to sata and usb ports.They can only expose them in motherboards according to chipset, x370 exposes all ,b350 some less and a320 least.

While I can't provide proof that it is a bandwidth saturation issue, there is a performance degradation when going from 16x to 8x. I don't really care if it is because the card can't draw enough power, bandwidth or is just feeling melancholy due to the 8x. The only thing that matters to me is that there is a performance degradation. I've seen huge variances as I've seen a number of videos but her is just a sample video - [youtube=lQGWiGfBJfo] [youtube=HchSu5peIoc] [youtube=rRyFGoDVr28]

SATA are conected to the I/O not directly to CPU. http://www.startlr.com/wp-content/uploads/2017/03/ryzen-processors-support-ecc-memory.png 24 lanes https://content.hwigroup.net/images/editorial/600/011745_intel_z370_chipset_block_diagram.jpg DMI uses 4 PCI 3.0 lanes so 20 total.

I am talking about AMD , that picture is correct for Intel but AMD has it like i describe ,sata is connected directly to cpu not chipset https://cdn1-techbang.pixfs.net/system/images/386561/original/95591d0c46dc785c56e2604f420ab508.png?1489487512 https://img.purch.com/w/755/aHR0cDovL21lZGlhLmJlc3RvZm1pY3JvLmNvbS9GL1IvNjU2MzQzL29yaWdpbmFsL2FtNF9ibG9jay5wbmc=

Son, look at the left side second row from top ,it says 2xsata and on the right side it says usb 3.1, where my source contradicts my statement, you think because there is some sata and usb ports coming from chipset that that invalidates my statement that usb and sata is directly connected to cpu?

EdInk:

AMD will just slap 2-4 more cores on the high-end CPUs thanks to infinity fabric. Intel has nothing on AMD in 2018

That doesn't seem sustainable. CPUs have long been at a level where they're powerful enough to be far away from being the system bottleneck, especially in games. Who's going to bother buy new a CPU when their old one has so much headroom while the GPU is shitting itself in semi-modern games? Most people don't have GTX x70s/x80s/Tis, and even those are the bottlenecks in games anyway if paired with any CPU that's not ancient. I've been wanting upgrade my GPU for a long time now, my CPU however, I wouldn't be surprised if I keep using my 4770K for another two years.

Find a motherboard that 100%, for certain, does what you're talking about maybe? And i'm talking about the SATA portion. And i do mean for CERTAIN. 99% of motherboards are going to use that SATA portion for 1 x4 NVMe drive. And the ones that don't, will likely not even use that portion of the SATA, since the chipset itself can provide enough SATA ports. As well your statement: "so mobo manufactures can't assign that 8lanes to anything else they are locked to sata and usb ports." Doesn't make sense. For USB, sure, but not for SATA. They can assign it all to 1 x4 NVMe drive or They can assign it to 2 SATA + 1 x2 NVME drive Or They can assign it to 2 SATA + 2x PCI-Express lanes. That is most definitely not the definition of "locked"

Sorry my bad about sata ports i completely forgot that they can be configured for something else beside sata, simply i put them with usb because they come from cpu and i totally forgot that that lanes can be used for something else. And the second thing about motherboard that supports sata ports from CPU there is bunch of them really bunch , but of top of my head here is one as you requested : ASUS TUF B350M-PLUS GAMING link : https://www.asus.com/us/Motherboards/TUF-B350M-PLUS-GAMING/specifications/ Look under storage section

Let’s not change the subject. The original statement was that Ryzen has 32 available lanes from the CPU and that is false.

Man , each Zen die has 32 lanes , it is quoted million times and it has been presented on every AMD presentation, and second my statement was about the fact that SATA and USB ports is directly connected to CPU (part of it), and third what you think from where did AMD pull 64 lanes for Threadripper and 128 for Epyc? That lanes are already there on CPU , AMD doesn't have separate mask for TR and Epyc , they just bin best dies for them

Again show me where you can use more than 16 lanes from the CPU on the motherboard outside of the M.2 slot. I don't care how many lanes TR or EPYC has. AM4 gives you access to only 16 lanes from CPU to use how you wish.

The title of this article is very odd. Intel has had octa-core Core i7s for a long time - in fact, the reason why I got a Ryzen 7 earlier this year was because I did not want to pay the premium for an octa-core Core i7 (6900K). It's much like the Coffee Lake news - Intel will release a hexa-core Core i7... as if hexa-core Core i7s had not existed before, LOL. The only newsworthy thing for the Core i7 would be a 12-core. Anything less has already been done.

It's pretty much mute point, but i'm not seeing what you're saying there under the storage section i'm seeing things like: AMD Ryzen™ Processors : 1 x M.2 Socket 3, with M key, type 2242/2260/2280 storage devices support (SATA & PCIE 3.0 x 4 mode)*3 AMD 7th Generation A-series/Athlon™ Processors : 1 x M.2 Socket 3, with M key, type 2242/2260/2280 storage devices support (SATA & PCIE 3.0 x 4 mode)*4 or 1 x M.2 Socket 3 with M Key, type 2242/2260/2280/22110 storage devices support (SATA mode & PCIE mode) But those are specifically talking about SATA mode, for M.2. Not actual sata ports. Personally, i'm not sure i understand the purpose of SATA mode, because to my knowledge, instead of using 4x PCI-Express lanes for the NVME M.2 drive, it instead runs over SATA. Theoretically, from what i've read, this frees up the 4x PCI-Express lanes(or up to 4x?), however, in these configurations, the extra 4x PCI-Express lanes can't be used for anything else? So you're freeing up the lanes to do...what with them? I could be very wrong in that, maybe they get freed up to use in PCI-Express slots....but that's not how i read it? But i'm also reading that is potentially automatic, depending on your m.2 SSD, and that some are designed for SATA mode and some are designed for PCI-Express mode, which again makes it all mute point lol

I gave you sata port and usb and provided link to mobo that utilize that feature set,what more do you want?

AMD Ryzen™/7th Generation A-series/Athlon™ Processors : 2 x SATA 6Gb/s port(s), gray, You asked for board that uses SATA ports coming from CPU because you were convinced that there are any , and i provided link to the board, now why and how Asus choose that path is up to Asus, but the fact stands there are sata ports from cpu,you can use second m.2 drive but if you are using that sata ports then you are limited to 2xPCIE lanes for m.2 . Granted if you are not using Samsung drives (fastest) you want be bottle necked by those 2xPCIE, lots of m.2(maybe even majority) want be able to utilize 4xPCIE.

Maybe there will be a miracle and we'll get PCIe 4.0 with the 9700k.
