So total 16 lanes from CPU? 16, 8/8, 8/4/4?
still wondering the latency differences between the two.Yep. And 24 or so from the chipset via the shared DMI interface.

I guess time will tell when we get real optane m.2 cards and someone tests the two ports....why is this not common knowledge :/
I do miss PCIe PCH slots :/ I would put my 10Gb E card in that so my GPU gets 16x lanes :/
I would not assume that is even remotely comparable.You can just look at PLX chips to get an idea. They tend to be 130-150ns latency added.

But I agree, we are nearing a point where we need more in mainstream terms.

this is why i would not make that statement. The different in latency and IOP from PCIe to Memory is microseconds to nanoseconds. I doubt there is only a 100ns delay in the PCH and added distance from CPU. It would be a better guess to say micro seconds differences vs nano seconds. But i still wouldnt claim shit without a real source. I find nano second difference to be BS given what little we know.
your assuming the PCH is the exact same. I would not assume such a thing. I have no clue how much farther the copper is, its cycles, assume there is no other types of overhead and so on. I have no idea how much father the path from the PCH is to the CPU and whatever else is going on conversions or whatever.Why isn't it comparable? It's the exact same concept.
What are you trying to compare with what exactly?
Some 100us NAND? 10us 3DXpoint NVME or some 250ns 3DXpoint DIMMs?
For 3DXpoint NVME drives a PCIe switch adds something like 1-1.5% latency.

You seriously talk out of your ass way too much and make ridiculous assumptions on things you have no knowledge of.
SATA goes through the PCH and its latency is horrific comparably. Is that because of SATA or PCH or both. I am not going to pretend i know. You can be my guest but until someone with real knowledge does a flow chart break down with latencies I am not making guesses.
Which brings me to a tangent...why is the average latency between all aspects of a computer not mapped? I am surprises there is no common knowledge flow chart of the latencies of everything on a computer.
I remember talks in the 90s or 2000s about BTX being better and worse for latecies between different parts and talks going on about making a better layout that is better for cooling and latency for computer parts. I remember the talks going on but never heard more than that. It was an interesting debate though.
i just edited. Check it again.If you think it somehow works differently, prove it. I supplied numbers on PCIe switching latencies.

You provided something that is irrelevant and not comparable and pretend that it is comparable with no factual basis. That is how bad misconceptions are created. I forget what it was but about 5-10 years ago there was this horrible misconception that would simple not die. It was when i used to post on a laptop forum. There have beena few over the years. Wish I recalled what they were :/
Oh one of them was application of TIMs...hell I still see it on this forum today about how air bubbles are formed.
The other had to do with CPUs or something. There were quite a few but whatever.
A classic is the flicker threshold lol.
According to PC Mark 8 storage suite, connecting via the native Z170 hyper M.2 socket provides a marginally faster connection when compared to connecting the Samsung 950 Pro NVMe SSD to the main PCI3 x16 sockets. However, just like in the synthetic benchmarks, the difference in performance is so slight between the two connection methods to be unnoticeable in the real world.

only place that has tested it but all the photos are broken. Also 950 PRO is not even remotely comparable to Optane so if their are latency issues it might not be noticeable until you throw Optane into the picture since optane is magnitudes faster....time will tell I guess.

The throttling is heat...its been known. I have never had throttling on my 950 PRO because my case isn't shit and has airflow.Sorry for 2nd post follow-up.
A big consideration is importantly using multiple drives/devices just like we do in real life and especially enthusiasts or more so prosumer.
This further compounds the contention sharing, which is not necessarily captured in a lot of these tests due to focus on a a single product storage device without other variables being introduced.

Well this is it. I want to run SLI, a soundcard and M.2 drives.

Yes the sound is being fed to whatever output you have selected. Remember that your integrated audio's primary job is to be a DAC. If there is no digital/analog conversion ocurring inside the PC, the audio has no reason to go through integrated.
If the audio were going out an SPDIF integrated onto the motherboard, it would, again, not really be going through the audio section of the motherboard (the ALC1150/892/etc chip and the capacitors/opamps, etc) so much as it would just be piped directly to the SPDIF port.
The information with digital out is just that- DIGITAL. Nothing needs to be done with it. It's just data. It remains a series of 0's and 1's until a digital to analog converstion occurs in your outboard DAC/stereo/receiver/TV/soundbar/etc.
The QUALITY of the digital to analog conversion is perhaps the single most important factor in deciding how good your audio will sound. There are DACs out there costing $14000. And there are DACs costing $50. Not only will the actual audio quality out of an expensive DAC be better, but it will support a wider range of formats and sample rates as well.
An entry level DAC may only support 44.1/48/96Khz and that's it. A high end DAC will support everything up to 5+Mhz (DSD). The best DAC's out there right now, as far as most people are concerned, not counting the "ridiculously expensive" stuff are the "Chord Hugo" and "Schiit Yggrsil""

"Ahhhh....makes more sense to me now. So since I'm using the hdmi out of my video card, the audio data goes through the motherboard and out the hdmi, and the onboard audio not helping in this case. The hdmi is going through my home theater receiver which is a Yamaha V377 500W 5.1 surround setup.
Thanks alot for your help, I have one more question for yaThe best my receiver can put out from the pc is a simulated surround mode. I figured from owning gaming consoles which have supported dolby digital and dts 5.1 for some time now, certainly pc gaming would offer those formats as well. But I never see them in the audio options of the games I've tried so far, GTA V for example. Only the option to select the type of speaker setup. This might be a silly question, but , am i missing something? Or do the games not support those formats?"

"The audio is going thru the HDMI cable and out the speakers, there is no additional "audio processing" needed, by the receiver, as all the receiver is doing is taking in 6-channels of digital audio, sending it thru it's DAC feature, then amplifying it and sending it out to 6 speakers.
The game itself has already done the "audio processing"."

3) Finally, newer NVIDIA GPUs such as the GeForce G210, GeForce GT220 or GeForce GTX 480 have added an internal HD audio codec. This is like having an internal sound controller built right into the graphics card. The NVIDIA internal HD audio codec can only be used to output to an HDMI (or DisplayPort) display. It does not support analog audio. If you require analog audio (i.e. for headphones or PC speakers), you must continue to use your PC's sound controller. The NVIDIA internal HD audio codec is superior to analog audio or S/PDIF signal. While S/PDIF is limited to compressed 5.1 multi-channel, the NVIDIA HD audio codec can support additional audio channels and also support more advanced audio formats used with Blu-ray movies. If you have a graphics card with internal NVIDIA HD audio codec, simply plug the HDMI audio cable from your graphics card to your HDTV and it will carry both video and audio. No other internal or external cables are needed from your sound card for audio.
For more information on the audio codecs supports, please view the Knowledge Base Article Which HDMI audio formats do NVIDIA GPUs support?

Most modern games I play work in 5.1, by the way.

So do most older games. The problem lies in what was used and what you have in your chain. In most cases, the format is going to converted and emulated and not true to the engineered recordings of the game developer.
Like older games used Miles Sound System, EAX, OpenAL, A3D....if your soundcard does not support these formats, it will play it in 5.1 still, but it will be virtual/simulated by the decoder used. The same thing with new games and the myriad of encoding that they use.
https://forums.geforce.com/default/topic/932657/3d-vision/dolby-atmos/post/4873463/#4873463 you can see some of the different old audio formats here
Since you will watch a lot of video, you'll probably be happy with an AVR. But if your serious about gaming, you should approach it like GibsonRed and his setup.

Miles is not a hardware library, it is purely software, same as A3D and will work across HDMI just fine.
OpenAL is also a software library which has a hardware implementation only available on Creative sound cards - it can output multichannel across hdmi with no trouble.
EAX has software and hardware implementations, but developers at the time mostly just went with the hardware surround method, so to get surround from this you need both DSound to OpenAL wrapper.
You will not get multichannel audio from any game using a hardware dsound output over hdmi, unless using the xfi titanium HD which has a hdmi port for this very purpose as it can route the wrapped dsound>openal output over its own hardware.
What motherboard do you have?
Sigh, want more news :/
I even have a google alert configured for "coffee lake" to email me.
most 4790K and 6700Ks his 4.5 and all 7700Ks hit 4.5 and most 7700Ks hit 5GHz and some hit 5.2GHz.How often do current i7's hit > 4.5GHz? Anecdotally, it seems the Sandy chips could do it much more frequently than Haswell and subsequent processors. If Coffee Lake does give us a 4.5 giggle 6c/12t i7, I will be absolutely tickled.

Kaby has amazing clocks. Which is why people are hopeful cream of crop of the cannonlakes will hit 5GHz
meant coffee lake.Cannonlake is mobile only
Desktop goes Kaby Lake(14nm+)->Coffee Lake(14nm++)->Icelake(10nm+).
Higher clocks for me please. I like old software
Then you're waiting for the wrong CPU, it's 14nm++ which is mostly meaningless marketing speak.Higher clocks for me please. I like old software
i was saying 14nm+ was marketing gimmick but than intel pushed an extra 400mhz max out of highest binned CPUs (4.8GHz-5.2GHz) which surprised me! Most Kabys hit 5GHz which is much better than the average for SKL (4.5/4.6?) so I wouldnt call 14nm+ a gimmick so if history repeats we might luck out again and find some more mhz improvements.Then you're waiting for the wrong CPU, it's 14nm++ which is mostly meaningless marketing speak.
The cream of the crop 14nm period is kaby, because only 4 cores. Adding 2 more isn't going to give us more frequency, it's going to take it away.
I suspect 5ghz coffee lake will be far far rarer than 5ghz kaby lake. I'm ok with that as long as it does 4.5 -> 4.6 kind of area. It'll still thrash Ryzen at a heap more benchmarks than it already does.
Wait, what makes you think there will be no 4C variant of coffee lake for desktop use?Then you're waiting for the wrong CPU, it's 14nm++ which is mostly meaningless marketing speak.

You keep saying this, but I really don't think it's true. Unless you delid, our make liberal use of the AVX offset, it seems most 7600/7700 will top out around 4.8GHz.
How likely is a 6C/12T i7 for less than 400$?
Where the hell did you see 7700k+ z270 for 300??!How likely is a 6C/12T i7 for less than 400$? Damn, I cant wait anymore, there were so many cpu deals in the past days where i live. I already bought a Ryzen 1600x because is was 30% off. Yesterday I saw 7700k + Z270 mobo for under 300 bucks after all kinds of rebates and cashback.
