Dell XPS 13 2015 Skylake Infinity Display Owners Thread

I think so. And the performance difference is minimal anyway.

 

I do not think that the gpu performance difference is minimal. And I believe it might matter to a relatively large group of potential buyers.

 

I'm talking about 6200 and 6500..
300mhz of clock and 1 mb of cache are the different..
Same ram, same display..

I can not decide whether to buy i5 version or i7, FHD.

 

Same for me..

I think I'll buy i5.. To spend extra money in case and thunder adaptor...

Anyway... There is something not really clear..

You put the frequency at the same value of i7, but you see less battery life?

Inviato dal mio Nexus 4 utilizzando Tapatalk

 

It is simple. What do you prefer, a very small increase in speed in real life for i7 for two hours smaller battery compared to i5.
I decided for i5 and I am very happy with this.

 

But you can reduce the frequencies ... And use same clock of the i5..
But some users said that is not exactly the same thing .. Maybe...

@iatrou how much is long your battery life?

Inviato dal mio Nexus 4 utilizzando Tapatalk

 

for cpu is small, but for gpu isn't small increase in speed...

 

What are you talking about? Both CPUs have same 520 HD Graphics. We are not talking about Iris model here, just regular i5 vs i7.

Regarding lowering the speed, I don't think CPU was ever fully maxed out, most of the time it was idling or its usage being at couple percent so it was already running at very low speed. It has not reached speeds that cannot be reached with i5.

 

Ok... Thanks..
Ok.. I think I'll buy i5.. I've already a good desktop pc..

all new xps 13 (no outlet) i7 processors have been replaced with the model with iris, so I was talking about these...

 

if you do not care for gaming or any kind of 3d accel go with the i5, hands down.

heck even if you do, i'd still go with the i5, its not like if iris graphics made it a great gaming machine. I can play battlefield 4 on the i7 iris with everything on low and its functional (while this would not really be functional on the i5), but its not great. i'd rather have a usb-c thunderbolt dock with a real graphic card, and 2-3h more hours of battery life if i wanted to play games. even if you do 3d graphics, you'll have 2h on battery (iris full own drains the battery very fast) so its not advantageous at all.

I got the i7 iris because through work it was complicated to get exactly the model i wanted, so i gave up.

in fact, to reiterate, i'd highly recommend i5+FHD. Put the extra money in other things like disc space or accessories, or a nice dinner - better bang for your buck!

 

Yesterday i started a thread about the possibility of a thunderbolt 3 external GPU option on the XPS 13. Since then i read a couple of news about most of them claimed the need of a bios option in order to activate an external GPU system.

At the moment i have a i7/HD520 but i´m not really sure if i should go for the Iris version because of the better graphic performance and because i´m not really sure if the eGPU support will come to the XPS 13 afterwards.

 

This is exactly my choice..
Good stuff!

if you're looking for a serious gaming laptop i'd just reconsider and get a bigger laptop with a discrete gfx card anyway, or just.. not a laptop.. much better experience on desktops. other than that things work. i just played some more bf4 on mine just to be sure it doesnt throttle, and it did not. again ,thats 720p all low graphics for it to be comfortably playable (and theres graphic artefacts because the intel driver isnt up to crap but whatever)

the tb3 gpus aren't ready yet but tb3 is supposedly standardized thus things should eventually work.

 

My keyboard and touchpad works exactly as supposed. However, on the rightmost side the buttons are tilted a to the right edge (aka, there is no space between buttons and the chassis.
The touchpad is also tilted a bit, and is flush on the right side, and the left side is appr. 1 mm lower. These are small aesthetic disturbances..


I checked another xps 13 today, and it didnt have the keys/touchpad tilted at all.
But most probably I will just keep it as is, since everything works like it should. I dont have any heat issues, coilwhine (so far), minimal red tint, ports aligned and so forth.

 

I have noticed that my trackpad is also susceptible to tilting. Whatever corner I press will usually result in the trackpad tilting in that direction. It's no issue really imo. Doesn't wobble or anything.

I've been really happy with the performance and graphics on my i5/8GB/128GB. The screen still flickers from time to time during heavy network activity even with Intel's latest display drivers, but performance and battery life is great. I have a desktop at home with an i5-3570k, 16GB RAM, and GTX 980 - and yet this little ultrabook does not disappoint when I'm out and about.

Nice... Cool!

Guys, do you know some USB-c adapter, with ethernet and hdmi, not much expensive, please?

Inviato dal mio Nexus 4 utilizzando Tapatalk

 

Good luck. I've been searching for this, but I have either found only hdmi or only ethernet adapters that are affordable or adapters that contain both, but were 100+€.

 

9-10 hours with 20% brightness. This was my primary concern not the cup.

 

Cool!

It's a bad news... And dell's adapter costs less? I found a simple cable USB c - hdmi at 14/19 euro.. But for now it's more important an ethernet... Mnnn

Inviato dal mio Nexus 4 utilizzando Tapatalk

 

Dell's own adapter seems to be the best here (it has all ports that I need in fairly compact package with not huge price): http://www.amazon.com/Dell-Adapter-Type-Ethernet-470-ABQN/dp/B012DT6KW2

Problem is that I can't find a way to get it in Europe. Both Dell's official site and above linked Amazon link only ship to US and I can't find it on any EU sites.

 

Review with benchmarks of the Iris model: http://www.computershopper.com/lapt...design-core-i7-with-iris/(page)/3#review-body

Interesting that the 2016 XPS 13 runs a bit slower than its competition for CPU tasks.

 

I'm in Europe too... I didn't search yet.. Mnnn...

Inviato dal mio Nexus 4 utilizzando Tapatalk

 

In italy is available.. But very expensive...
100 euro!

They are claiming it has an HD 530....

 

From the review: "Just know that the Core i7 on the gold model may not be faster on all tasks than a Core i5, so if you play only the occasional casual game, you're better off saving $250 or so and opting for the $1,399 Core i5 model."

I think the i5 is the most balanced model.

 

My trackpad does not tilt when pressed, it is always ever so slightly tilted. Might make an service errand of it later if it starts to act strangely, right now im just satisfied everything else works as it should

 

I think that If you want to play.. You don't have looking for an ultrabook... Maybe..

Inviato dal mio Nexus 4 utilizzando Tapatalk

 

We all have different requirements, I am traveling a lot so I value a laptop that is as portable as can be and if possible - allows me to game when I feel for it.

 

Maybe you have to chose another pc if you want to play.. It's impossible have all... Unfortunately..

Just ended a 3 hour long gaming session, works for me

 

Had a 2 hour gaming session on my iris i7, QHD yesterday.

Played rocket league at 1920x1080, on max settings. Was getting high 20's to low 30's fps. Works for me too.

The QHD screen is excellent, watching 4k video on YouTube (albeit a bit downscaled), the quality is great.

 

If you want one, today would be a good day: 31.4% off.

I currently have two xps's. One with iris graphics and one with the HD520. Is it possible, and if so - how difficult would it be to swap processors between the two units?

 

Well you have to replace pretty much the entire Motherboard, this is going to be a lot of work tough. May ask why you would like to do this?

Can you compare both units in terms of noise?

 

There would be no point-- you'd have to swap the mainboard which is a lot of work. Moreover, to do that, you'd need to break it into the components completely. You might as well just swap the SSDs...

Unless... is it because your 520 has the FHD screen and you want to make a model with Iris + FHD? That's quite an interesting project, and I think if you want to attempt it the forum will aid you in your quest for knowledge .

I'd like to add a request for the temps you're getting on your IRIS model btw

 

Well it is because the battery life is very reduce on the iris graphics and I'm not really going to play any demanding games on this device. According to HWinfo, if i stay idle on both machines, the 520 draws an avarage of 2.4 w and the iris is 4.2, which is almos twice... I'm getting 8-10 hours with the iris, and 13-15 with the 520. All the other settings are identical, and so are the specs.

The temps are about 6 degrees different between the CPU's at idle

The reason is that i got the i7-6500u init and the touchpad was not working 100% - so dell sent me the new i7-6560u. The touchpad is very differerent and i really like it, but the battery is 30-40% worse. I'm not sure if this is completely due to hardware or maybe a software glitch as well. Now im not sure if i want to send back the Iris or the 520..

 

Sounds like Dell needs to release a BIOS update to better support the 6560u similar to what they previously did with the 6500u. While the 6560 should draw more power it shouldn't be anywhere close to that big a difference.

 

Does anyone else have problems with the WiFi disconnecting randomly? I have no other problems other than my connection going dead every few hours. Kills my connection for around 90 seconds, then comes right back. All other devices on my router continue with no problems, and it happens on multiple types of brands of routers.

 

I've heard the Broadwell wireless cards in the XPS 13 have these issues. People have had success moving to an Intel card.

 

I havent had any issues so far (except my slightly tilted trackpad and non-centered keys), but, two days ago I installed the beta driver for 540 iris. Surfing and light tasks went as before, but when I started to game I noticed differences.

AoE2HD - lagged, has not done it before. Brushed it of as internet issues.
CSGO - 50-60 fps instead of 100-120. Started to investigate.
Started Minecraft, 20-25 fps (pre was around 80).

Another issue found its way to my laptop. It might be possible that it is not due to the driver but just emerged now.
I was running on battery without battery saver, everything was as it should. When I reached 50% battery the battery saver started, which also gave way to buzz/coil whine when scrolling (both in chrome and edge). I played around with it a bit, but as soon as I connected the pc to a powersource the buzz disappeared.

So I rolled back to non beta drivers and now Im back to my previous performance.

Have been using battery saver mode for around 30 minutes now, and havent notized any buzzing...

 

Are you able to stop it from throttling while gaming? AFIK it will only stay at 25 w for a few minutes and then it will go down to 15, meaning the CPU/GPU can't run at full.

 

I havent checked, tell me how to check throttling and Ill do it on my next session
(that said, I have stayed at the same fps for up to 3h gaming, but its not the most demanding games in the world)

 

Run throttlestop 8.10 in the background and alt-tab occationally, or install Hwmon and check the monitoring graphs. ty

 

Guys,

I'm about to pull the trigger on one of these machines, but still debating to go for the standard 6200U/HD520 or high end 6560U/HD540. What obviously puts me away is the throttling issues and how it affects the FPS on high CPU demanding games such as CS GO.

@BallRoller
Would you mind sharing your FPS @ 1024x768 (low details) on CS GO ?

@Eason
How bad is the throttle ? If it throttles down to 15W as you mentioned, then there is no real point to have such a high setup as even the 6200U/HD520 when fully loaded would overcome this enveloppe. I'm not sure repasting helps either as this is purely power throttle, right ?

On the other hand, it seems like the SP4 from Microsoft does a better job and can sustain 20W with the i7/HD540 using an external USB fan so that's a massive difference - but battery life sucks.

Decision's time !

 

The sp4 throttles because of case temps as well. It draws more power than the adapter! The iris model still will perform better in games than the 520, that's guaranteed-- but you might need to disable turbo to avoid it going over the tdp while gaming. Rest assured I will do very extensive testing and do a write-up on the performance for ultrabookreview.
