That's precisely what the MUX chip is. FYI "mux" is short for "multiplexer". Both GPUs (or more) connect to the MUX device, then it has a switching mechanism to pass through a single signal to the display. Think of it like a HDMI or composite switcher box that was used back when TVs only had 1 input and you need your DVD/VCR/Playstation all connected at once and you flicked the switch on the mux.

iGPU ----- Mux ---- Display Tcon
dGPU---/

What SRSR333 is talking about, is using software to control the MUX chip. This used to be done on older switchable graphics designs where you often had to reboot, or at least restart the display server. In Linux you used to do this by restarting the X server. Whether you have to do a full reboot is entirely up to the OS and how well it handles dynamic recognition of PCIE devices. For example, Linux can be made to detect the GPU and then you only have to restart X to switch (rather than reboot the whole machine). I imagine Windows is probably capable of that as well but would need some work on drivers.

EDIT: eGPUs work with a similar predicament. Many of which can be attached/detached with a running Windows system. So you would just need to combine the GPU detection with something to flip the MUX output and you should be fine.

 

What I said is true, in the situation he describes both chips would be connected at the same time and dynamically managed, where as in the current MUX setup only one controller is connected at any time.

Some older schemes allowed restarts but not with anything running (it likely quickly set to software rendering before passing it back over to the other, so hardly seemless).

HA! i knew it! thats what i had in the back of my mind the whole time@gsync with optimus

and thx for clearing that up prema

muxed clevos, whoooo! but i guess itll only be an interim solution, until manufacturers implement adaptive sync with switchable graphics *ugh*

@Prema - you're a genius, as always. How'd you get/know about all these cool stuff? Maybe it's just Prema. There can only be one Prema.

Prema is love, Prema is life.

 

Him working on the Clevos' BIOSes help quite a bit. He has to have some sort of insider access to give BIOSes to people like Mythlogic who partner with him, etc.

 

YOU guys did that (helping to shape the direction of the new models)!

This thread was no joke, it was put up upon a 'request':

http://forum.techinferno.com/showthread.php?t=8226

The originally planned P6-refresh had no MUX, the GTX980M had 4GB and the 14" had no GTX970M...there are actually companies that listen.

 

HOW DID I NOT SEE THIS THREAD?

I'd have harassed for 120Hz 8-bit colour panels, PCH cooling (if applicable), larger single power bricks, keyboards on the quality level of the D900x era and iGPU functionality access for Quicksync acceleration for the desktop GPU models (not in a Mux format; but making use of the desktop chipset).

I blame only myself *cries in corner*

 

Just post whatever you like in there, its never too late...let's see what the future may bring.

 

Wow time goes by fast, I remember when that thread was first made and I was like oh man I have to wait almost two years for these new laptops, but here we are in 2015. Can't wait to see the P870DM

 

Does that mean Prema works for Clevo? I merely thought he was an expert hacker... Clearly I was mistaken.

Good to hear that such companies still exist in this day and age of Apple, Microsoft, EA and Bioware where they:

• Dictate what you can buy
• Control what you can do with what you buy
• Milk every last penny, pound or dollar for cheap add-ons that should cost very little
• And break support for very good products

Clevo, is in essence, the CD Projekt RED of the computer/laptop industry. I just wish HTC did the same in the smartphone industry.

 

You are telling me...I am waiting for it since it was still bearing another name...it looks really sleek & cool btw...

It'll be my first SLI, will treasure it...expect some sweet support from my end.

I mod for no-one under the "Blue Sky" except 'Your freedom & Your choice'!
Free as a Phoenix ( ͡° ͜ʖ ͡°)

 

Oh... oh boy. I need to think this over and make a list =D.

I'm gonna sleep on it and when I wake up do it. Then clean my laptop.

Maybe not in that order.

 

I like how @D2 Ultima and @Meaker have already begun recommending redditors to check out the Clevo P640RE.

Just ran a Google search on "P640RE" when I found your replies, guys.

 

I'd recommend other manufacturers to users...

But I don't see any other manufacturers.

I have this thing where I don't recommend people get gimmicky/overpriced/throttle-prone/etc laptops. With the last (current) gen, Clevo was the only choice, excepting the GT72/GT80, but at that price point, the P7xxZM and P37xSM-A models were better. So what was the purpose of MSI? ASUS has lowered their price point quite a bit, sure, but their support is worse than nonexistent, and their stigma of dying after a few months to 1 year is well warranted, as well as their incredibly high chance of being a "lemon" and then going into RMA hell. Even if the ASUS models work amazing and are cheap like the clevos, for that fact alone they automatically are disregarded in recommendations.

The only models where Clevo didn't have a presence is in the gigabyte/Aorus/Blade/GS line which is super thin, but let's be honest... those notebooks really have no place. There is NO POINT in hardware a chassis cannot handle in 99% of scenarios. I'll say that forever. Hell, the P34x manages to throttle 970Ms if you play stuff like Crysis 3. Like... HOW does one throttle a 970M? There's people who have +500MHz stable OCs in P650SEs without throttle due to thermals.

 

wow, im flabbergasted! i didnt think clevo would listen to such an extent and especially this quickly!

 

Is Clevo not choosing to implement UniDIMM slots instead of DDR4 throughout their Skylake refreshes? The latter type of RAM is still very expensive compared to DDR3.

 

isnt unidimm also pretty expensive because its so rare?

 

UniDIMM is a slot standard, so it (technically) would be cheap to make.

 

sure, but if there isnt much interest in the market and theres only a handful of suppliers, id guess that those rare sticks would be quite expensive as well...

 

As I mentioned before - UniDIMM is a slot standard that simply fits both DDR3 and DDR4. There aren't UniDIMM modules. So it should be cheaper.

 

aaaaah ok, here i thought ud also need special unidimm stick formats but how would that work? if u simply put two "gaps" instead of one into the sockets, then ud be missing the connection of some pins, no matter what kinda sticks u install...

I'm glad I decided against buying a P750DM-G right away and wait for the P870DM, hopefully it'll have a 4k G-SYNC display.

You'll love the SLI system. I really liked having the extra gpu in my alienwares.

 

now thats a biiiig extra incentive to go for a P870DM, folks! being the future prema machine itll get the magic overdrive! extended prema support

A company listening to it's customers and potential customers makes too much sense. But I'm confused that a company is actually doing it. This is not normal, unfortunately..

As I posted in the speculation thread, I hope they know when not to listen too. It seems they do, the DM didn't go backwards with the few cries for optimus/iGPU and battery at the cost of performance. It's not thinner at the cost of cooling. Clevo seems to embrace performance first. That shouldn't change. This P640RE will be the baddest 14" on the planet.

Even when we express the changes we want to see, it's important to let Clevo know they are doings things right too. I don't want them to change the great things they are doing. Continue to innovate! Intel said BGA mobile only. Clevo said more desktop CPU models. Continue to improve. The ZM was a big step from the SM. Continue to lead. They did not leave high performance. P570WM ~ no competition in it's class, P870DM ~ no competition, P7xxDM ~ no competition.
.

 

turning into a clevo love fest, me likes

 

I think Prema is the only user who has never used a SLI machine before that I don't need to send my guide to XD

 

My P570WM with 780M sli was my first dual nvidia card setup ever and I was fine

 

But I wrote my guide after you had your machine =D.

Besides you're meaker, I could probably sit here and ask you stuff all night and you'd not finish talking. If you chose to answer in the first place =D.

 

I tend to avoid talking tech too much with people, they tend to get a glazed look after a minute or two

 

There will be a P870DM-G but not sure about it supporting 4K...

Getting an SLI system doesn't equal using two GPUs...

 

Gents - we're talking about the P640RE here, a lean, mean machine like the F-22. Let's not bring in behemoths like the P870DM (Antonov An-225) to this discussion.

 

No, because the Razer/MBP chassis is part of the reason for their heat/noise levels.

I mean, I'd like the look/materials of it, but there's only so much power you can fit in a slim chassis before heat/noise become an issue. Not sure that Clevo internals/pricing would overcome a chassis that is too thin for its components (not to mention a metal chassis actually contributes to a hot surface/keyboard).

 

Well - as I mentioned in the 2015/2016 speculation thread, heat only matters as long as we continue to rely on semiconductors for computing. Moore's law is already beginning to fail, about seven years before its predicted unravelling. We haven't got much time until our nodes become so narrow that the transmission coefficient of electrons tunnelling through the barrier becomes very significant and our CPU nodes cannot get any smaller.

We then have to rely on photons, or spin states of particles to continue the law.

Hence, yes, I would certainly like Clevo internals in an MBP/Blade chassis. Hell, make it as thin as a gold MacBook if you can.

 

I'm not sure I understand your reasoning. How would Clevo internals improve the Razer/MBP situation?

 

Perhaps you failed to read my first paragraph, or I wasn't clear in linking the two together.

I mean that once we get to a state where cooler computers are possible, I don't want thickness and weight where it is superfluous.

Even with the current Razer Blade, the heatsink design is inherently terrible. A couple of tweaks to the hardware design such as a sanded or a block metal contact plate, an improved fan profile and some rearrangement of components could go a long way in decreasing temperatures (by, say, 15°C). That would bring the Blade down to W230SS temperatures, which are still fairly high also because of poor thermal design, and could be lower.

Skylake CPUs already run much cooler than their Haswell counterparts with slightly more processing power at approximately the same clock rate.

 

That makes more sense then. Your wording didn't make it clear that you were talking about after we transition to cooler computers (at least not to me).

I agree, no need for bulk if it doesn't lead to better cooling. If I could have a machine as thin as an ultrabook with heat/noise levels on par with an ASUS G751, I'd take it in a hearbeat (tip - the G751 is virtually silent even under load).

 

Oh man, hopefully it will have a 4k option otherwise dual 980's will be overkill for 1080p

I was originally going to get the P750DM-G with the 4k display but one 980 will struggle, that's where two 980s would help in a P870DM-G

Wasn't there supposed to be a 4k P770DM-G? Or will that just be a regular P770DM with a 4k panel (no G-SYNC)?

Edit: Nooooooooo 4k will not have G-SYNC but it looks like we can have only ONE GTX 980?

 

yeah, was about to say: P870DM will only sport ONE 980 at the moment. gotta wait until the regular sized MXM 980s are out, which will have a lower tdp and thus lower performance. will still smoke any 980M sli setups though if you couple them up

 

Assuming there will be MXM 3.0b 980 cards...

 

just caught prema in the other thread mentioning that clevo should be releasing those in the near future...lemme check for that particular post

edit: here you go - http://forum.notebookreview.com/thr...hoenix-has-arisen.781814/page-2#post-10096225

nothing for sure yet, but it does look promising

 

Thou underestimateth me

 

damn right, i bet D2 could make it through AT LEAST 3 minutes, if not 3.5!

 

It is planned but not ready, yet...

 

Gents - once again - small-laptop talk here. The P640RE is the spiritual successor to the W230SS, not the P770ZM or even the P650SE...

Try to stay on-topic, guys.

 

no TB3
no i7-6820HK ie. no overclocking

So close clevo

 

You want an i7-6820HK in a 14" laptop to do heavy overclocking?

You are looking for the wrong size and thickness of laptop.

 

Well said. Hell, those who've put quad-cores in their W230SSes usually under clock and undervolt. Only the GPU is OCed.

Some people want everything... Remember our good friend MK4C?

 

The GPU is only OC'd because maxwell cards are so cool and it's such a weak card.

Don't even remind me

 

*Searches for dude who overclocked 860M to stock 870M/780M level*
