Dell XPS 15 2-in-1 9575 benchmarks + temps

I love sharp text, so not having the 4K screen will be a bummer, but for everything else I spend time on (media/games) 1080P is more than fine. I've had my MBP 1600P next to a 1080P monitor watching 4K videos from YT and it was pretty hard to tell a difference most of the time.

I actually love the idea of a 2-in-1 - but I haven't actually owned this form factor. I had the Surface Book 2 for a month - but ultimately didn't like the detachable setup (and the screen had major BLB). This setup is a quick conversion - you just flip it around. The SB2 was too much of a chore to use. Although using a 1lb 15" 4 core tablet with a 3:2 screen was pretty epic.

Glad to hear it's cool on the bottom - I don't get what the other commenter's issues are if his is "burning up" his lap. Weird.

 

Lol not spam at all, no worries. The reviews that I saw on the GS65 showed 6 hours with playback and 8 hours with regular use. I agree with getting to the internals was a pain on my GS63, although I didn't think the quality was lacking. I would own an Aero 15 if their support wasn't so terrible. Any laptop that gets a thumbs up from iunlock for cooling is probably pretty darn good.

I can tell you that the 9570 and 9575 are both going to be casual gaming laptops, nothing like the Aero or GS65 for sure. The 9575 is NOT a gaming laptop by any means, just a decent laptop that can play games as well.

The fans scream on it when you're doing cpu intensive stuff, so even with your egpu they are going to be running loud.

I do like the 2-in-1 for studying/reading however.

 

Looking at the GS65 internal shot on NBC shows they do the "flipped" motherboard setup, and I don't see any way to easily access the M.2 slot to upgrade the storage, forcing my hand to buy the 2499 config to get at least 512GB of storage. I do like that it seems to run quieter. I had the 7577 in my hands for a while, even the i5 model, but fans were still in the 47-48 dBa while gaming (this is where I don't get how Notebookcheck does their fan noise tests). The Aero15x is only using a 2 pipe cooling system, but does look like 2 VRMs are integrated into that active cooling system at least. But the fans look small, thus the need for them to be extremely loud to cool the system.

I totally get that the 9575 is not a gamer laptop; I'm fully informed there. I used to have at the Alienware 13r3 with OLED. If that screen wasn't just a bit too small, I would have stuck with it. However it was just a bit too heavy.

Maybe I'll just stick with my bootcamp, scripted up, bootloader hacked Macbook pro with eGPU - maybe I should just bite the bullet with the 15" price. I hope the 9575, which is less than 1500 with 2 year warranty though, will be better than you describe in the fan noise department. Perhaps it's just one driver update away.

 

Yeah the GS63 had the flipped motherboard as well, I did a repaste on it. It wasn't too painful, but I've taken hundreds of laptops apart. The 7577 ran much cooler and quieter than my 9560 and 9575. I do hope they fix the fan profiles. Frank said they would work on it, but he also said that the 9570 wouldn't suck and the jokes on us.

*on edit*
also I think Lisa @mobiltechreview said that the thunderbolt ports on the HP have 4 lanes.

 

Is this on her review of the new Vega chipset Spectre x360 15? I asked their support and they said it has 4 lanes as well, but I'm wary. For 1499, a 4K equipped MX150 sounds like a good deal if it can support full fat eGPU bandwidth.

 

yeah it was on her vega x360 review.

*on edit*
also running 20 minutes of far cry 5 the bottom of the laptop is still not hot. I'm not sure how netflix would heat it up unless you are absolutely cutting off all airflow.

 

So I have the 9575 in my lap playing a 4k HEVC video of Deadpool while I study on the desktop (yes the sound is off). 20 minutes in and the laptop isn't really even warm let alone hot.

 

Fans while running the 4k video?

Your commentary verifies the overall surface temp improvements that Notebookcheck measured. It looked to be cooler than my Macbook Pro ultrabook is under load, which is great.

I verified with HP chat agent - she said 4 lanes on the Vega chip, 2 lanes on the 8550U model.

SO I take it when gaming - you just plug headphones in to cut out the fan noise?

 

So the fans weren't really running. In fact the cpu really didn't have to work to decode the 4k hevc video since the cpu can do it hardware wise. Perhaps it was a poor test. I just am not sure what nextflix video content would cause so much load.

I have only played games on it to test it out for this thread. I would have to use headphones to play on it for sure with how loud the fans are.

Lame they only did 2 lanes on the 8850u model. I wonder if the x360 is limited to 45w by HP like the dell is. It would be cool if they left it at the default 65w. I really thought about picking one up but the battery life doesn't seem to be great.

 

If you really want to bypass PL1 & PL2 throttling, Uncle Webb has some good tips to get you started. There are posts with these schemes working with various Intel gen 6, 7, and 8 CPUs but YMMV. Do some careful research as this could kill your laptop if not supported or executed incorrectly...

​

 

I am using Netflix on Edge. The cpu temps are in the mid 50's but the bottom of the unit is HOT. I have the all black unit from Best Buy as opposed to the Dell silver exterior one. Maybe it conducts heat differently then the ones everyone is testing?
Im stumped.

 

Seriously doubt that the black one wouuld have different construction besids the obvious ones. What tool are you using to verify this and how?

 

Hardware monitor to verify temps. My lap and touching bottom of pc to verify this thing is hot.. i see the reports of great cooling and think - in no way would i consider this cool. or even slightly warm.

 

Well I don't have netflix to test it. How much of your CPU is being used by nextflix? That 4k file only used like 5% of my cpu and it was at 5watts. No fans and no need to have them either.

 

Well, cooling might mean different things, heat does not just disappear, cooling in a laptop is the art of making the heat go elsewhere

 

Doing some video encoding right now, spoiler: it throttles at stock settings.

Up for any other tests/games/whatever people want me to throw at it.

Also found out it gets much better Cinebench R15 scores when undervolted.

 

Throttles to what freq? I noticed in NBC's review, the i5 model would be around 2.9 Ghz in their stress test, but the i7 looks like it oscillates between 2.9 and 3.1 Ghz most of the time. IN games, the i7 seems to hold a higher freq as well, and gets into the 70s for temp.

 

Throttles around 3.1ghz from 3.4ghz in handbrake. I'm not sure which test you're referring to on NBC, but if you look at the prime95 you see they both throttle to the same thing.

 

Gee, plz give some warning before releasing such bombs

 

In the graphs for both in Prime95 it looks like the i7 likes to oscillate up to 3.1 ghz more often where as the plot for the i5 is stuck at 2.9Ghz solid. In the WItcher 3 test, the i7 is at 3.7Ghz, and i5 is at 3.4Ghz. I know the overall conclusion was they were pretty close, but it does seem like the i7 does offer somewhat of an advantage. No big deal though as it likely won't be that measurably difference, but it is there.

Also, I find it debatable to say it's "throttling" in handbrake if it is maintaining it's base clock and even reaching into it's turbo.

So bottom line man, are you going to return it or keep it? You are probably like me in that you return most of the laptops you buy.

 

Debatable to ask a cpu at this day and age to run at it's turbo? I guess we will differ in our terms there.

I haven't decided if I will keep it or not. If it had 16gb of ram I would probably keep it, but I feel like I over paid for what I got. I typically don't return many laptops, I usually use them for a couple of months or more then sell them and try something else.

 

How are the fans treating you? I was just putting my hands on one in Best Buy and decided to do one last look at what people are saying about their experiences and excessive fan noise when charging at no load was a frequent complaint?

Leaning 9575 over the GS65 (look and feel wise I just don't love it...) but fans that are mentally unstable is a deal breaker...

 

So the fans aren't too bad as long as you're not doing anything strenuous with it. I was worried because I had the crazy fans with charging but the bios update 1.1.1 fixed it for me and the couple times that I've charged it since I haven't had that issue.

For the most part the laptop is super quiet and the fan profiles are totally reasonable. When really using it they spin up like mad.

 

Interestingly enough, Dell just released 1.1.1 BIOS again with a 21 May date of release. I wonder what happened with it? I also see the BIOS mentions eGFX docks and improved performance. Wonder what that means.

Thanks for all your answers - it still sounds like mostly a winner. Cool, relatively quiet for everyday tasks (light computing), great screen (saw a YT video of the 1080P version, and the colors looked great). BUT, now that the Matebook X is launching for a steal....I'm wondering again. DAMMIT TECH WORLD

 

I only see a MX150 version of the laptop, is there something with more gpu behind it?

 

I'm not really comparing the raw CPU/GPU power of the 9575 to the Huawei, but rather just looking at an option over my current Macbook Pro 13.

As stated before, I use an external graphics dock (eGPU) with my Macbook Pro, but it's quite the hacked setup and requires full shutdown and reboot to get it functioning. Thus I've been looking at alternate windows machines that would work well with an eGPU.

I would have just picked up the older 9560, but the 2 lane TB3 port held me back. The 9575 looks like a great companion, but could be tricky because of the AMD/nVidia conflict. However, Notebookcheck got the same eGPU box as I own working with the 9575 so I should be ok (at least on an external display).

The Huawei just looks like a great price for a gorgeous MBP clone with a better screen (touch plus aspect ratio). It has a 4 lane TB3 port as well, so it could very well meet my desire, while being more compact and portable the XPS15 2-in-1.

Sorry, this is off topic though from this specific thread.

 

So I did notice that my 960 Pro runs much hotter than in my 9560 and even 7373. Turns out there is gore tex on the bottom cover where the thermal pad for the SSD makes contact (kind of defeats the purpose of having thermal pad connecting the SSD to the cover). I realize it helps the bottom temps, but at the expense of the SSD... It idles at 35C and easily gets up to 45C. In my 9560 it idled at around 25C and I don't think I ever saw temps above 35C. If I keep the laptop I'm going to have to find a replacement bottom cover to fix all the things that Dell messed up... At least the SSD is still fast, lol.

 

More stupid engineering.

 

Yeah, in all honesty I didn't even look the first time I had it apart. I figured "nah they wouldn't do something so stupid as to insulate the thing they are trying to cool with the thermalpad..."

 

Is the Gore for insulation or dissipation? I thought it was the latter.

 

Gore tex is an insulator. It's been used for a long time in high end jackets because it insulates well and also repels water. Dell is using it to keep the heat from soaking into the case/keyboard and provide a better end user experience.

 

Well sadly I think I'm going to return the 9575 to Dell. I like the system quite a bit and may get one with 16gb of ram down the road, but Dell wants $1700 bucks for it, that seems nuts. We will see if something pops up in the outlet for a reasonable price. Any benches someone wants me to run before I send it back?

 

So mainly because of the memory restriction? I am still waiting to see progress on my supposedly shipped 9575. But I have the i7/16gb model. Once ebates completes the cash back, it will have cost just under 1500, but thats with 2 year warranty.

 

Yeah mainly the 8gb. I am also pretty disappointed in the AMD drivers as well, but I could live with that I suppose. It's hard to justify the extra 300 bucks prior to coupons to get the 9575 vs the 9570...

 

Ridiculous to sell a device with 8gb of soldered max ram in 2018 for well over 1000 USD

 

Well sadly I setup a return for the 9575 and ordered a 9570. I have a feeling I will miss this keyboard more than anything, lol. I just can't justify $1799 to go with the 9575 and 16gb of ram, that's nuts. I could get a Razer 15" for that price.

 

Hello surface PRO!

 

Figure I'll bump this back up. I do miss the keyboard of the 9575, probably my favorite part about the laptop.

 

Still think this is funny:

 

You know, it's actually not bad at all. I do find it fatiguing though.

 

Hah maybe because I'm used to typing on Cherry MX Brown switches all day I never had that problem?

 

My fingers get this weird unsatisfied feeling where I really want to keep pressing lol

 

Yeah I could see that. Overall how is the laptop treating you?

 

It's decent. I bought it because I wanted to try grading with a stylus on pdfs, but ultimately it isn't nearly as accurate as a pen with xodo so my writing/comments look terrible. Not really working in that regard. Gaming performance is quite decent, runs Prey and Doom 60 fps at FHD on medium settings. Works reliably with my eGPU, so that's good. Not loud when plugged in for that, as well. Other that two cores being 10C hotter than the other cores (new heatsink coming tomorrow), it's really a great machine. I do miss type-A ports, though.
