EVOC P750DM2-G or EVOC P650RS-G for image/blender video and VR dev

Hi all experts,

I'm a big Clevo fan since my precious W110er (4 years old a "XMG"), I'm going to make a new choice and already take our Evo expert seller, for the Prema bios, the display calibration and the really good mail relation from Donald.

What I want to be sure it's the new model I have to buy, a 15'' and a Gtx 1070 from Hidevolution for sure !

What I want to do is photo stuff, blender modelisation/render (so Cuda features) and Unity and/or Unreal engine VR post production, this could be done under a linux machine.

I pretty sure I've to take a 4K screen, for the photo and video editing.
1) don't really anderstand the difference between the 4K Samsung PLS LED from the P650 and the 4k from the P750, could some one give me some information ?

What I looking for, for my blender machine is to have the Intel for display and the Nvidia for Cuda render stuff
2) is it possible from the both Evoc's machines (I don't see any Intel iGPU from the 750DM2-G data sheet) ?

What I like with my W110er is the format and the power, what is missing from this WonderfullMachine is Ram capability and battery life time and a retro keyboard.

At this time, I've a sdd with Windows and a sdd with linux distro and I switch (2 minutes, open the machine, unscreww and switch)
3) Could I do this easily with both models (if I need to do this again and now under the new M.2 PCIe standard ) ?

The big differences beetween both models are :

• The upgradable capability
• The dimension
• The battery time

4) Something else I've to take in my decision ?

Thanks in advance for all returns

 

1. You will find virtually no difference between a Samsung PLS, LG IPS or AUO AHVA screens...they all use essentially the same technology. All three give you vibrant colors and work beautifully outside in direct sunlight.

2. The EVOC P750DM2-G uses the desktop processors, so it does not have an iGPU and does not use nVIDIA Optimus Technology.

3. You would not have to do this since both models have 2x M.2 slots and 2x 2.5" SSD Bays. You can have both drives in your laptop at the same time.

 

Actually, it does have an iGPU. All the mainstream desktop processors do (there's no skylake enthusiast-line processors yet, only up to Broadwell-E) but the iGPU is completely turned off and there is nothing attached to it in the PxxxDMx models, so it might as well not be there. But I mean, if you put it into a barebones desktop build, it'll have an iGPU to use, for example.

 

Thanks for this return,
so if I take a P750DM2-G with a i7-6700k let see the spec here, all the graphical features exist on a barebone desktop build ?

Then what sorte of bios (PREMA) features or/and mother board capability we have or gonna have (CPU Video spec are differents from notebook builder so) ?
Where could we get information so ?

And one the other part, if I take a P650RS-G I gonna have the possibility by the bios to have the iGPU or the dGPU, all informations on this could be cool for me too?
Like this be done by stop the dGPU's alimentation, so no more visible under the machine or more like make the video display available by the iGPU (HDMI, dp, eDP ....) so what could be done with the dGPU in this case ?

Thanks for all return, I'm trying to find what are display/video features available for the both machines.

 

Ah the old XMG A102 / 110ER ;-) Great little machine in its day, things have moved on a lot though since 2012 and you'll notice a massive difference between that and any of the current aluminium chassis 15" models.

The P650RS-G (XMG P507) has a MUX switch, so you can switch the internal display between:

- Optimus equivalent (MSHYBRID) setup, where the lapotp will use the iGPU or dGPU depending on the load and thus gives you more battery life
- Discrete mode which routes the dGPU signal straight to the internal panel. This bypasses the iGPU, gives you less battery life but it is required to run G-Sync. You can change the switch between "Discrete" and "MSHYBRID" mode in the software Control Panel that comes with every laptop or in the BIOS. You need to restart the lapotp in order to complete the change.

In this model, all the external display outputs are linked directly to the Nvidia dGPU, this is not affected when you change the MUX switch setting. You can run the internal display and 3x external 4K res displays simultaneously.

Donald touched on the panel question but there's an important difference. The Samsing 4K 15.6" ( LTN156FL02-101 ) panel is an RGBW panel, sometimes called Pentile. It is a similar type of panel used in some phones and primarily created to cut costs and reduce power consumption comared to a typical RGB panel. Compared to the Sharp 15.6" 4K panel ( LQ156D1JW04 ) the Samsung not only has the RGBW pixel matrix problem but also it performs much worse on Black Level figures and contrast ratio than the more expensive Sharp panel does. Finally the AdobeRGB coverage of the Samsung is 47% whereas the Shark is 61% AdobeRGB ( 96% sRGB)

If you're going to be using the laptop for any sort of serious image work then I would strongly advise against using the Samsung 4K. No alevel of calibration will improve the quality of the panel and on a low Gamut panel like this you will only have any sort of accuracy towards web content.

Hope this helps.

 

I would say the p650 in this case due to want of optimus and battery life. The desktop cpu models do pack a punch but the mobile ones are not worlds apart.

 

Let's be honest the 6700K is worlds apart compared to the 6700HQ

 

I highly doubt Blender uses CUDA or OpenCL for rendering. And even though it might support those for RT rendering previews, there are a lot of shaders that will not work. For proper CUDA based rendering you are better of using something like Octance render.

Now since we ruled CUDA out, rendering will benefit greatly from the 6700k. I use my system for Houdni/3DS Max daily and this processor makes hell of a difference. Obviously nothing compared to the multicore workstations, but still leaps ahead of the 6700HQ/6820HK based notebooks.

 

@bloodhawk Blender supports CUDA and OpenCL for GPU acceleration ;-) Even a 980 (compared to what the 10 series could do, I haven't seen any benchies on this yet) will half the scene render time compared to a 6700K.

 

Gotcha. I haven't used blender much for rendering. But from experience in engines like Vray / Mantra / Arnold, none of them support advanced SSS/Displacement shaders over CUDA. Real Time previews however work just fine, till the time you dont use something like the ones mentioned earlier.
