13" Dell XPS 9350 + HTPC (Gigabyte Z170 ud5 th) + GTX1080@32Gbps-TB3 (Razer Core) + Win10 [tintin]

Recommended Posts

I finally received the razer core and i'm pretty happy with it. It's working fine with my dell xps 13 (9350) and also with my streacom fanless htpc (gigabyte z170 ud5 th).

Just had some drivers and firmware issues but now it's perfect plud and play.

For the procedure is:

- update xps bios 1.4.4 (other dell drivers are also up to date)

- update thunderbolt firmware 1.02.06

- install older thunderbolt driver 15.3.39.250 (had some issue with the newer one)

- desactivate thunderbolt secure option in bios and enable th boot option

- install razer synapse 2.20

- install intel vga driver 4454

- lower the power output of the wifi card to 75% or 50% (may work without but seems to give more stability as it seems to interfer...)

- shutdown, plug power in razer core then attach thunderbolt cable and power up the laptop

- install nvidia drivers (21.21.13.7254) and reboot

 

I also did some bench of my geforce 1080 in the htpc (6600k) using a 16x riser and then with the core attached:

 

  6600k 16x   6600k core   dell xps 13 core   dell xps 13 igpu
screen external   external   internal   internal  
firestrike ultra 5 179 100% 5 086 98% 4 678 90% -  
firestrike extreme 10 578 100% 9 614 91% 8 078 76% -  
firestrike 22 324 100% 18 068 81% 13 124 59% 1 339 6%
time spy 7 124 100% 6 828 96% 6 032 85% -  
heaven ultra 2 646 100% 2 350 89% 1 674 63% -

 

 

As espected scaling got worse when fps are high because of thunderbolt x4 bandwith but it's acceptable at 60fps (10-15%)

Seems a perfect on the go VR solution, my rift is working fine on it. Will make some VR tests later with the xps...

Your work is perfect, thank you :)

 

I wondered if it was relevant to have an eGPU setup like the Razer Core later with my TB3 laptop (MSI GS60). 
But I was afraid there was a massive performance drop, but with your investigation, I see there is only a minimal performance drop when the GPU is pushed to the limit !

Hi! How did your VR testing go? I have an XPS 15 9550 with a GTX1060 in an Akitio TB2 enclosure. Most VR titles for the Rift and Vive work fine, but I am encountering judder in Virtual Desktop and Bigscreen (both Rift and Vive versions).  When I turn on the VR performance monitor in Virtual Desktop, I am seeing <= 10% headroom in performance.  I re-tested with a GTX 1070 FE and got similar results.

Hello

 

If i'm right the msi gs60has a quad core so you will have better scaling than me from my desktop... when i have time will complete the benchs with xps13 on external display thats make it also better.

For now i didn't try virtual desktop or bigscreen but will have a look if i found the time. I didnt see any notable difference in the demos and  the games i tried (EVE, chronos, project cars).

You mean you have problems when you are playing non vr games in stereoscopic mode?

No the problem (judder) only manifests itself in Virtual Desktop and Bigscreen, which are both VR apps
